The present paper provides a taxonomic revision of the genus Fecenia with emphasis on the characteristics of the pre-epigynes which are integrated for the first time into an identification key. As a result, one species is revalidated, Fecenia protensa Thorell, 1891, stat. n., and two new junior synonyms for Fecenia protensa are recognised: Fecenia sumatrana Kulczyński, 1908, syn. n. and Fecenia nicobarensis (Tikader, 1977), syn. n. New records are reported: Fecenia ochracea (Doleschall, 1859)from Malaysian Borneo, Fecenia macilenta (Simon, 1885) from Sumatra, Indonesia, Fecenia protensa from Thailand and Malaysia, Fecenia travancoria Pocock, 1899 from Sri Lanka and Thailand, and Fecenia cylindrata Thorell, 1895 from Thailand and Laos. Additional information on the biology of Fecenia is provided and the validity of characters for identifying Fecenia species is discussed.

Representatives of the spider genus Fecenia are distributed from southern India to the Solomon Islands. They are not known beyond the latitudes of 25°N and 15°S. To date (
Pre-epigynes do not occur in all entelegyne spiders, but seem to be common within the families supposed to be related to Psechridae (
Part of the spider material was collected by hand during an expedition in Thailand and Laos from October-December 2009. Further material was obtained from colleagues, who collected specimens in different regions of SE Asia. Most of the material examined in the present study was borrowed from several natural history museums, which are listed below. Examinations and illustrations were made using a Leica MZ 165 C stereomicroscope with a drawing mirror. Photos of living spiders were taken with a Canon EOS 500D (equipped with a Sigma 105 macro lens and a Canon ringlite). Photos of preserved spiders and copulatory organs were taken with a Sony DSC W70 compact camera via the ocular of the stereomicroscope. The material was preserved in 70% denatured ethanol. Female copulatory organs were cleared from surrounding hairs and dissected. The opaque tissue surrounding the vulva was removed. Vulvae were cleared in 96% DL-lactic acid (C3H6O3). As the cuticle surrounding the epigyne may curl and structures may get shifted in the course of applying lactic acid, this method could not be applied to every specimen. In males, hairs along the margin of the cymbium were removed to give a clear view of the bulb structures.
All measurements are in millimetres (mm). Leg formula (from longest to shortest leg) and leg spination pattern follow those in

Terminology of structures belonging to the copulatory organs is given as follows:
The female epigyne consists of two slits, which separate the lateral lobes (LL) from the median septum. The latter is folded transversely, resulting in a transverse edge or ridge (TR) (Fig. 79). Consequently, an anterior part of the septum (AS) and a posterior part (PS) can be distinguished (Fig. 79). Anteriorly, each of the LL exhibits a more or less sclerotised margin (anterior margin of lateral lobe, AML). The entire epigyne is surrounded by an epigynal field (EF), which is a sclerotised area. It is not as intensively sclerotised as the median septum or the LL and is distinguished from the adjacent areas of the ventral opisthosoma by a darker colour. The following structures certainly do not belong to the epigyne, but they may be of additional taxonomic information, so they are illustrated and described here, too. Namely the two muscle sigilla (epigynal muscle sigilla, EM) in front of EF (sometimes they are integrated into the epigynal field) and the slit sense organs (SO) near the epigyne (Fig. 79). The vulva consists of an internal duct system (more precisely a folded slit system, cf.
Apart from structures of a male palp that are well known in arachnology, e.g. conductor, sperm duct or RTA, the Fecenia palp shows a retrolateral patellar apophysis (RPA), a ventral patellar apophysis (VPA) and a membranous process (MP) close to the embolus base (Fig. 8). In one species, Fecenia macilenta, an additional large apophysis arises dorso-retrolaterally from the tibia (dorso-retrolateral tibial apophysis, DRTA, Fig. 53). Presently it cannot be clarified whether this apophysis is just the dorsal branch of an extended RTA or an additional apophysis. In either case, the DRTA can be regarded as an autapomorphy of this species.
Symbols/styles used in the illustrations: Regular solid lines indicate edges/margins/rims of structures as recognised in the respective view; Weak solid lines indicate edges of fine structures, e.g. membranous structures, or wrinkles in the area of the epigyne; Dashed lines indicate inner walls of ducts and/or slits; Dotted lines (wide) indicate structures shining through the cuticule (e.g. parts of vulva shining through epigynal cuticula). Dotted lines (fine) indicate clear colour differences (e.g. border of epigynal field). In schematic illustrations showing the course of the internal duct system the spermathecal head area is marked with several “T” marks, the copulatory opening with a circle and the end of the fertilisation duct in the direction of the uterus externus with an arrow (see e.g. Fig. 3). When a copulatory opening comprises an elongated slit/area, the circle is put at the central position of that slit/area. Arising points and/or directions of tegular appendages in males are described as clock-positions of the left palp in ventral view. This refers also to directions of some structures of the female vulva. As a convention in this latter case: In every species only the right vulva half is considered.

Results Characteristics of pre-epigynesDistinction of pre-epigyne from adult epigyne. Pre-epigynes are considerably smaller than epigynes. If there is no adult female available to compare the size of the epigyne with that of the pre-epigyne of a subadult female the slit sense organs (SO) and epigynal muscle sigillae (EM) in front of the pre-epigyne can help. The distance between the SO from left to right side is about twice as long as the width of a pre-epigyne, but only slightly longer than the width of an adult epigyne. Furthermore, the pre-epigyne is only slightly longer than one EM. The adult epigyne, in contrast, is at least twice as long as EM. Moreover, the pre-epigyne exhibits either no epigynal field or the latter does not reach SO and/or EM.
Ontogeny of the epigyne. Pre-epigynes from four pseudo-orbweaverspecies were examined and found to exhibit apparently species-specific characteristics. Basic structures of adult epigynes can be recognised as primordial structures in the pre-epigynes. The following general ontogenetic process apparently leads from the primordial to the adult female copulatory organ: The anterior part of median septum (AS) and the anterior margins of lateral lobes (AML) extend strongly anterio-laterally.
In the subadult female of Fecenia protensa Thorell, 1891 the transverse ridge/edge of the median septum (TR) is clearly recognisable as a broad “W”-shaped edge (Fig. 69). In addition to the changes that happen from the subadult to adult stage described above, the median section of TR becomes strongly notched, together with a distinct median folding of AS. The result is the characteristic adult epigyne (Figs 55, 64, 108).
In Fecenia cylindrata Thorell, 1895, AML run at more or less a right angle anteriorly and face each other. This can be recognised overall in pre-subadult, subadult and adult females (Figs 79–82). A clearly developed TR is only present in subadult females and adults. In pre-subadult females the TR is at best only slightly indicated (dotted line in Fig. 82).
In Fecenia ochracea (Doleschall, 1859), it is easy to identify corresponding structures of subadult females and adults, because the pre-epigyne (Figs 20–21) already strongly resembles the adult one (Fig. 19). TR is present in subadult females. As on both sides TR is strongly curved anteriorly the characteristic broad-“nose-like” AS, like in adults (Fig. 19), is already recognisable. By contrast, in pre-subadult females TR is at best very weakly developed (Fig. 22).
In Fecenia travancoria Pocock, 1899, the situation is very similar to that in Fecenia protensa, although its pre-epigyne (Fig. 74) slightly differs from that of Fecenia protensa (Figs 58, 69) (see respective species descriptions).
Different developmental stages of pre-epigynes. Epigynes of adult females within the same species are similarly shaped (this is the reason why they can serve as an identification tool). In general this applies to the pre-epigynes, too. Yet, in one out of fifteen subadult females of Fecenia cylindrata the pre-epigyne was larger and somewhat differently shaped (Fig. 80) than generally (Figs 81, 94). It gives the impression that it may be further developed than the others. This phenomenon of a differing character state of the pre-epigyne does not mean that identification via the pre-epigyne is not possible. Because if the respective pre-epigyne is interpreted accurately, it is noticeable that it tends to fall along a developmental continuum together with the “regularly” shaped pre-epigynes, the pre-pre-epigynes of p.s.a. ♀♀ and the adult epigynes (Figs 79–82). The s.a. ♀ of Fecenia cylindrata illustrated in Fig. 80 is already more similar to the adult (Fig. 79). Its pre-vulva already exhibits a clear division into a transparent section of internal duct system (TSI) and a strongly sclerotised one (SSI) (Fig. 86). Hence, it is clearly recognised as Fecenia cylindrata.
In summary, pre-epigynes are easily distinguished from adult epigynes and apparently exhibit species-specific characters (note that one species pair Fecenia protensa/Fecenia travancoria is difficult to distinguish, but this is not surprising as it applies to the adults too; see respective species descriptions). In rare cases, in Fecenia cylindrata pre-epigynes of particular subadult females may differ from the general type. But by the means of an accurate interpretation of those pre-epigynes the respective subadult females can be recognised as Fecenia cylindrata, anyway. So, in Fecenia the pre-epigynes can be used as an identification tool. Here they are integrated in an identification key for the first time.
Taxonomy Psechridae Simon, 1890In combination, the following characters are diagnostic for Psechridae: cribellum and calamistrum present; claw tufts distally on the 3-clawed tarsi; rectangular calamistrum comprising at least 3 rows of setae; indirect eyes with grate shaped tapetum (
1 | AME smaller than or as large as other eyes; opisthosoma ventrally mostly with white or beige median line; clypeus at least twice as high as diameter of AME; legs II and IV almost equal in length; build horizontal, dome-shaped sheet webs | Psechrus |
– | AME larger than all other eyes; opisthosoma ventrally mostly with pair of white or beige patches, never with light median line; clypeus not or just slightly higher than diameter of AME; leg IV shorter than leg II; adults build vertical pseudo-orbwebs | Fecenia |
http://species-id.net/wiki/Fecenia
Fecenia species differ from Psechrus in the following characters: AME larger than all other eyes (in Psechrus, AME smaller or at most as large as other eyes); ventral side of opisthosoma centrally with pair of two white or beige patches, never with light median line like in Psechrus; clypeus flatter than in Psechrus, not or just slightly higher than diameter of AME, hence cephalic part of carapace rather flat; leg IV always shorter than leg II (in Psechrus, leg IV slightly longer or as long as leg II); in contrast to Psechrus, males with RTA, RPA, VPA and MA; females with clearly divided median septum of epigyne, vulva always lacking spherical spermathecal heads (in Psechrus females, median septum simple and spherical spermathecal heads generally present).
Medium sized to large Psechridae, body length in males: 7.2–13.2 mm; females: 7.7–20.2 mm. Cephalic part of carapace not distinctly narrower than broadest (thoracic) section. Anterior eye row recurved, posterior row straight (or at least almost straight). Chelicerae strong, shorter than in Psechrus, basal article at most 2.5 times longer than broad. Cheliceral furrow with three promarginal and four retromarginal teeth. Basal article of chelicerae ventrally with long field of short, transverse striae. Ventral surface of former distally with semicircular lobe with long, curved hairs (Fig. 6). Labium slightly longer than broad (Fig. 5). Gnathocoxae ca. twice as long as broad, distal section slightly broader than basal one (Fig. 5). Serrula with ca. 130–170 (size-dependant) very small, dark, apically blunt teeth, very densely arranged. Sternum slightly longer than broad, with pointed posterior ending and broad-angled (160°) anterior ending (Fig. 4). Pedipalp in females with single claw (Fig. 51) containing 8–12 teeth. Legs extremely long in males (metatarsus I ca. three times longer than carapace (Fig. 117), relatively long in females (metatarsus I ca. 1.5–2 times longer than carapace, Fig. 119). Leg formula 1243. Coxae of legs I, II broader than III, IV. Calamistrum dorso-retrolaterally on metatarsus IV consisting of 3–4 rows of setae (inner rows irregular). Spination of palp and legs: Highly variable within each species. Therefore, no species-specific and no common genus-specific spination pattern could be found. Consequently the spination will only be listed for the primary type specimen in the species descriptions. At the following positions spines are always absent: All patellae, dorsal surface of all tibiae and all metatarsi. Palpal femur spination varies from 000, 010, 110, 120, 130, which are the most common ones, to 141. Palpal patella, tibia and tarsus mostly without spines, if present, then very small, the most common patterns in this case are: patella 110, tibia 0100, tarsus 1004. Femora of legs I and II with even more variable spination, e.g. 100, 110, 210, 300, 310, 312, 320, 401, 412, 501, or 613. The most common one is 310. The same for those of legs III and IV, but here the number of spines is lower on average, most common is 010. The tibial spination pattern in Fecenia includes a characteristic aspect: Legs I and II: retrolateral spines absent; legs III and IV: prolateral ones absent. At each opposite side the number of spines varies from 0 to 4, with legs I and II mostly having one to two spines more than III and IV. Ventrally at tibiae I and II there are mostly 6, at tibiae III and IV mostly 4 spines (paired spines at all tibiae). The spination of metatarsi is more conservative: I–II 2015, III 1025 or 1015, IV 1015 (ventrally the four proximal spines are paired). But there are exceptions, too. Colouration: Chelicerae, carapace and sternum yellowish brown to dark brown. In rare cases specimens exhibiting a darker carapace margin and a median longitudinal band. Sternum unicoloured. Legs from yellowish brown or light brown to brown, may be annulated. Tibiae I and II in some cases darker than other limbs/legs. Femora at distal third often with dark, annulated patches. Opisthosoma dorsally greyish-brown with yellowish patches. Heart region with darker lanceolate patch with light centre (Fig. 119). Distal half of opisthosoma dorsally with two converging rows of dark brown spots. Lateral surface of opisthosoma is covered with 3–4 larger yellowish patches running diagonally. Opisthosoma ventrally dark brown to black, centrally with a pair of white to beige patches (Figs 116, 118), which differ intraspecifically in size and shape. In some cases those patches are fused, in extremely rare cases absent. Additionally, with white to beige transverse patch in front of spinnerets/cribellum (Fig. 116). The whole body is covered with grey hairs (Fig. 116). Spinnerets are relatively short and conical, except for median ones, which are distinctly smaller, slender and cylindrical. Bipartite character clearly visible in posterior spinnerets. Copulatory organs: Male palp with almost round tegulum (T). Embolus (E) filiform, arising in prolateral half of tegulum (T) and at least twice as long as conductor (C). The latter membranous, mostly arising centrally on upper half of T (Fig. 8) and mostly shorter than median apophysis (MA). T next to E-base (Fig. 8) with membranous process (MP). MA relatively large with general retrolateral direction (e.g. Fig. 89). Cymbium distinctly broader than palpal tibia and patella (e.g. Fig. 62). RTA differently shaped among the particular species, DRTA only present in Fecenia macilenta (Simon, 1885) (Figs 53–54). VPA often slightly bent anteriorly (e.g. Fig. 87). RPA mostly small and inconspicuous. Palpal femur modifications, e.g. ventral bulge as present in some Psechrus species, absent in all Fecenia species. Scopula dorsally on cymbium present in the same form in all Fecenia species (Figs 99–101), but less distinct than in most Psechrus species. Female epigyne generally broader than long, with folded median septum (e.g. Fig. 55). Anterior part of median septum (AS) larger than posterior part (PS). Anterior margins of lateral lobes (AML) iin some species strongly sclerotised (Fig. 108). Vulva simple, with internal duct system divided in three sections: Transversal section (TSI), strongly sclerotised section (SSI) and fertilisation duct (FD) (Fig. 83). Borderline (BL) between TSI and SSI clearly recognisable and often of taxonomic importance.
The pseudo-orbweavers are found in shrubs and trees, and also in the canopy (Deeleman, pers. comm.). Fecenia suspends its vertical pseudo-orbweb (Fig. 120) in the vegetation, mostly between twigs. The web possesses an enrolled leaf at the hub serving as a retreat. This is true for adults and later instar juveniles of all Fecenia species. Earlier instars build an elongate cone-shaped tube as a retreat, which is disguised with small prey remains and soil- and leaf-particles. The very early instars do not even build a pseudo-orbweb, but a rather conical or dome-shaped web with the retreat at the top of the cone. This web can be found in the herb layer too (
Predatory behaviour was observed in the lab using several Fecenia cylindrata and Fecenia protensa specimens. In each case the spider was transferred to a large cylindrical glass (30 cm high, diameter 20 cm) with a leaf, already partly enrolled, placed at the bottom. The next day the leaf was suspended by threads in the middle of the glass, a day later it was already fixed at the top. The pseudo-orbweb was completed another day later. After placing a house fly into the lower area of the web it took a few seconds until the spider stretched its two forelegs out of the retreat, and after ca. 1 minute it came out. The fly was grabbed with the chelicerae and immediately dragged into the retreat. A few centimetres before the leaf entrance the spider turned and crawled backwards into the retreat. In the case of larger prey items like crickets, the spider was extremely shy and careful. It took two or three attempts of coming out of the leaf and escaping back into it, sometimes interrupted by 5–15 minutes within the retreat. During the last attempt the cricket was bitten for about 7 minutes at the capturing site of the web before it was dragged to the retreat. Binding behaviour, as described in

Measurements of palp and legs. Palp 6.3 (3.5–6.7) [2.2 (1.3–2.4), 1.1 (0.5–1.1), 1.2 (0.7–1.3), 1.8 (1.0–2.0)], I 17.2–40.7 [4.6–10.8, 1.3–2.9, 4.7.7–11.3, 4.5–11.4, 2.1–4.3], II 23.5 (10.8–24.5) [6.4 (3.0–6.6), 2.2 (1.1–2.2), 6.4 (2.9–6.8), 5.9 (2.50–6.2), 2.6 (1.3–2.7)], III 13.6 (6.6–14.6) [4.0 (1.9–4.3), 1.6 (0.8–1.7), 3.3 (1.5–3.5), 3.2 (1.5–3.4), 1.5 (0.9–1.7)], IV 10.0–21.4 [5.7 (2.7–5.8), 2.0 (1.0–2.1), 2.6–5.8, 2.5–5.3, 1.2–2.4]. Leg formula: 1243. Palpal claw with 10 (8–11) teeth. Spination (holotype from Ambon [except for leg I as well as tibia and metatarsus of leg IV, which are lost in holotype: spination of SB 474 from Ambon is listed instead]). Palp: 110, 000, 0000, 0000; legs: femur I 533(423), II 313, III 213, IV 111; patella I–IV 000; tibia I 3008, II 3006, III 0025, IV 2024; metatarsus I 2025, II 2025, III 1025, IV 1026. Copulatory organ: Anterior part of median septum (AS) of epigyne broad-“nose-like”, slightly broader than its posterior part (PS). Lateral lobes massive (Fig. 1, 102). Epigynal muscle sigillae (EM) mostly integrated in epigynal field (EF). Slit sense organs (SO) mostly outside EF. Vulva with relatively short and narrow transparent section of internal duct system (TSI). Strongly sclerotised section (SSI) compact, duct with two curves (Figs 2–3), apex of first one directed posterio-medially, of second anterio-laterally. Primordial copulatory organs: Pre-epigyne: Already strongly resembling the adult epigyne (Figs 20–21, 104). All major structures present in adult epigyne are recognizable in the pre-epigyne, too (of course much smaller). Epigynal field not or only poorly developed, EM far outside epigynal field (Fig. 21). Pre-pre-epigyne (antepenultimate instar): AML far shorter than in pre-epigyne and transversal ridge/edge of median septum (TR) hardly recognisable (Fig. 22, fine dotted line). Pre-vulva: Pre-receptacula bulbous/spherical and relatively close to each other. Distance between centres of pre-receptacula less than 3 times of diameter of one pre-receptaculum (Figs 23–24). Colouration: Male and female: As described for Fecenia in general, but white to beige patch in front of spinnerets may be rather unclear (Fig. 118), smaller or even absent. In one (SB 98, from Mindiptana, Eastern Papua Province, Indonesia) out of 103 specimens the light patches ventrally on opisthosoma are absent. Variation of copulatory organs: Among male specimens examined, cymbium differing at most slightly in length (Figs 11–18). In some specimens MA may be more massive (Fig. 10) or T slightly broader (Figs 9–10) than in others. Shape of prolatero-ventral lobe variable (Figs 7–10, 96). One specimen differing slightly more from the paralectotype of Fecenia buruana (Figs 8, 12, 16) from Buru island (which is the closest male record to the type locality, Ambon) than the others. This is SB 95 from Mindiptana, Eastern Papua Province of Indonesia: MA directed to 2:30-o'clock position (Fig. 9), embolus (E) slightly longer than in the other males examined, RTA broadest distally (Fig. 9). Additionally, T protruding a bit more out of cymbium (Fig. 13) than in the other specimens. In females intraspecific variation is higher. The shape of AS (Figs 1, 19, 27–33, 102) as well as the course of AML are highly variable. Number of SO varying among specimens without geographical dependence. Vulvae of the specimens examined show less variation than epigynes. The initial part of SSI may be slightly more prominent (Fig. 38). Further on, the position of SSI seems slightly shifted in some specimens (Figs 25, 34). Pre-epigynes also differing in shape of AS and in course of AML (Figs 20–21). Based on almost 80 females examined, all the variation described so far is neither geographically fixed, nor are there distinct forms of variants which recur here and there. In some cases females from exactly the same recording site show clear differences. And on the other hand females which are recorded in different localities, partly hundreds of km away from each other, look strikingly similar. Anyway, the following ‘form of females' has to be discussed separately (see remark below).
The vulvae of the holotype of Fecenia cinerea (SB 404) (Fig. 40) and the specimens recorded from Mindiptana, Eastern Papua Province of Indonesia (SB 96–98, 442) (SB 98 illustrated in Fig. 44) differ from all other females examined. The duct of SSI is somewhat longer, especially the second curve (Figs 40, 44). Consequently, the course of the internal duct system of these specimens (Figs 41, 45) differs from the remaining Fecenia ochracea females (Figs 3, 35, 37, 39, 43, 47). However, the vulvae of the holotype of Fecenia cinerea (SB 404) and female SB 98 do not correspond completely. In SB 404 the second curve of SSI protrudes more strongly in a lateral direction. In one specimen (SB 97, not illustrated) from Mindiptana the second curve of SSI is a bit shorter than in the others from this locality. The epigynes of SB 96-98, 404 and 442 differ in shape (SB 404: Fig. 28; SB 98: Fig. 32; others not illustrated). According to the differences in the shape of the vulvae (see above) it may be justified to revalidate Fecenia cinerea Hogg, 1914. However, the difference is little (second curve of SSI slightly longer than in Fecenia ochracea) and thus does not provide evidence for a clear species delimitation; especially considering that in one specimen from Mindiptana the second curve is again slightly shorter. In addition, if the females from Mindiptana should be regarded as Fecenia cinerea, then the male (SB 95, Figs 9, 13, 17), which was recorded from exactly the same locality, should be placed here, too. However, as discussed above, the palp structures of this male only slightly differ from the ones of other Fecenia ochracea males (though these differences are worth mentioning as intraspecific variation). Moreover, no males have been recorded from the type locality of Fecenia cinerea so far. Consequently, I refrain from changing the taxonomic status of Fecenia cinerea. More material from the type locality of Fecenia cinerea, especially males may enlighten this “problematic case”.

Females distinguished from other Fecenia species except Fecenia travancoria by having anterior margins of lateral lobes (AML) anteriorly more or less converging and surrounding epigynal pit partly and the anterior part of median septum (AS) comprising a longitudinal, anteriorly pointed folding (Fig. 55); moreover, by having a notched transversal edge (TR) of median septum. Distinguished from Fecenia travancoria by borderline (BL) between strongly sclerotised section of internal duct system (SSI) and transparent section (TSI) running almost transversal (Fig. 56). In males RTA short, at most ½ the width of palpal tibia, and knobbed, almost as broad as long (Figs 62–63, 98). Median apophysis (MA) almost semicircular and shorter than width of tegulum (T) (Fig. 62, 98). In contrast to the similar male of Fecenia cylindrata embolus (E) without basal apophysis (bEA) and ventral patellar apophysis (VPA) arising proximally on patella (Figs 60–61, 99).
MALE:Body and eye measurements. Carapace length 3.1–4.4, carapace width 2.1–3.0, anterior width of carapace 1.4–1.9, opisthosoma length 4.1–6.4, opisthosoma width 1.6–2.6. Eyes: AME 0.25–0.27, ALE 0.17–0.18, PME 0.18–0.19, PLE 0.17–0.19, AME–AME 0.14–0.22, AME–ALE 0.07–0.19, PME–PME 0.18–0.25, PME–PLE 0.25–0.34, AME–PME 0.13–0.19, ALE–PLE 0.10–0.18, clypeus height at AME 0.29–0.35, at ALE 0.21–0.26.

Leg formula: 1243. Copulatory organ. Retrolateral patellar apophysis (RPA) rather inconspicuous (Figs 61–63, 98–99). Median apophysis (MA) with tip in ca. 1:00-o'clock-position (Fig. 62) and in retrolateral view almost straight (Figs 61, 99). Embolus (E) arising in ca. 7:30-o'clock-position on tegulum (T), distally thicker than in Fecenia cylindrata and at most as long as width of T. The latter almost round. Membranous process of tegulum (MP) reaches far up, mostly 10:00–10:30-o'clock-position. Conductor (C) small, size and shape similar like in Fecenia ochracea, arises medially in upper third of T.

Measurements of palp and legs. Palp 3.5–5.1 [1.2–1.7, 0.6–0.9, 0.6–1.0, 1.1–1.5], I 19.2–26.8 [4.8–7.0, 1.5–2.0, 5.4–7.8, 5.1–7.2, 2.4–2.8], II 11.3–16.5 [3.0–4.3, 1.1–1.6, 3.1–4.7, 2.7–4.0, 1.4–1.9], III 7.1–10.6 [2.1–3.1, 0.8–1.3, 1.8–2.6, 1.5–2.3, 0.9–1.3], IV 10.7–16.0 [2.8–4.4, 1.1–1.7, 3.1–4.6, 2.5–3.6, 1.2–1.7]. Leg formula: 1243. Palpal claw with 8–11 teeth. Spination (immature holotype of Fecenia protensa from Nicobar Islands in poor condition! spination of holotype of Fecenia sumatrana from Palembang, Sumatra listed instead). Palp: 110, 110, 0100, 1004 (spines on patella, tibia and tarsus with only half the size as those of femur!); legs: femur I 310, II 320, III 011, IV 020; patella I–IV 000; tibia I–II 3006, III 0023, IV 0024; metatarsus I 2025, II–III 2015, IV 1015. Copulatory organ: Epigyne in general appearance characteristically rounded-“W”-shaped (Figs 55, 64, 108). AML mostly strongly sclerotised, converging anteriorly and surrounding epigynal pit partly. AS clearly broader than PS. Epigynal muscle sigilla (EM) integrated in epigynal field or at least located very close by, same for slit sense organs (SO) (Figs 55, 64). Vulva with medium sized (longer than in Fecenia ochracea, Fecenia macilenta and Fecenia travancoria, shorter than in Fecenia cylindrata) and broad TSI (56, 65, 109). SSI more slender than in all other Fecenia species, duct with 2–3 curves (Fig. 57). Primordial copulatory organ: Pre-epigyne: “Crown”-like (Figs 58, 66, 69, 110). Primordium of AS already recognisable, broad “W”-like. Epigynal field not or only poorly developed, EM far outside epigynal field (Fig. 69). Pre-pre-epigyne: Prongs of the “crown” small (Fig. 70). Pre-vulva: Pre-receptacula bulbous/spherical (Figs 59, 67–68). Distance between centres of pre-receptacula more than three times diameter of one pre-receptaculum. Variation of copulatory organs: Cymbium length of male palp differing slightly among specimens examined (Figs 60–63, 98–99), MA may be extending further beyond retrolateral cymbium margin (Figs 63, 98). T in some specimens slightly broader (Fig. 98) than in others. RPA may be slightly larger (Fig. 63) than in general. In females the shape of AS may vary, e.g. the posterior notch is larger and the anteriorly pointed longitudinal folding is as such hardly recognisable (Fig. 64). Number of SO among specimens varying without geographical dependence. TSI varying in length (Fig. 56, 65). In dorsal view BL direction of vulva varies from 8:30 (Fig. 65) to almost 9:30-o'clock-position (Fig. 56). Pre-epigynes differing in shape of TR (Figs 58, 66). The most frequent shape seems to be the one of SB 216 (Fig. 69) and holotype SB 620 (Figs 58, 110). Number of SO varying strongly.
Pre-vulva may be slightly more structured (Fig. 67).
The reasons for revalidation of Fecenia protensa and the synonymy of Fecenia sumatrana with the former are as follows: In Thailand, Malaysia, Singapore and on Bali at several localities subadult Fecenia females were collected together with adult females respectively, which showed the characteristic rounded-“W”-shaped epigyne. The pre-epigyne of the subadult female holotype of Fecenia protensa (SB 620) matches the ones of the subadult females mentioned above. In
Reason for synonymy of Fecenia nicobarensis with Fecenia protensa: Although the types of Psechrus nicobarensis were not available on request it became obvious that

Colouration: As described for the genus Fecenia.
This species is very similar to Fecenia protensa. There are only fine differences in characters of the vulva (see diagnosis). Up to now, no intermediate forms concerning the shape of vulva have been found. Though it cannot be fully excluded, it seems rather unlikely that Fecenia travancoria is a junior synonym of Fecenia protensa. Generally, in Fecenia species the vulva shows less intraspecific variation than the epigyne. By now I consider Fecenia travancoria as valid species. But with more material from the southern Provinces of India, especially males, it may be possible to clarify this ‘difficult taxonomic case'.

The pre-pre-epigyne (antepenultimate instar), although hardly useful for species determination, may bear important information. In some Fecenia species both pre-subadult and subadult females were available for examination. A continuous developmental trend from pre-pre-epigyne (p.s.a. ♀♀) to the epigyne of adults can be traced (e.g. Figs 19–22 for Fecenia ochracea, Figs 79–82 for Fecenia cylindrata).
The present study reveals the occurrence of a different developmental stage of the pre-epigyne (penultimate instar) in the pseudo-orbweaver Fecenia cylindrata (Fig. 80). The following preliminary considerations may explain this phenomenon:
In insects a juvenile hormone (JH) regulates the development of the larva throughout the several moults up to the imago. Following
On the other hand it is known from spiders that the number of moults, and thus the number of instars, to reach maturity may differ, for example in Pisauridae (see above). In Latrodectus mactans (Fabricius, 1775) the number of instars varies from 7 to 9 depending on food supply (
In Fecenia it seems to be rare, that the pre-epigyne of a particular subadult female differs from the ones of the others belonging to the same species. But, anyway, as the example of the subadult female of Fecenia cylindrata (Fig. 80) shows, this phenomenon may appear. In such a case additional consideration concerning the identification of subadults is necessary. Does the respective subadult female fit into a conceivable developmental continuum for the species in question? This is, of course, much easier if several “regularly” developed s.a. ♀♀ and/or p.s.a. ♀♀ are available. As the pre-epigyne of a “further developed” s.a. ♀ most likely resembles more an adult epigyne than a “regularly developed” one does, it should not be too difficult to identify it. Thus, in Fecenia the pre-epigynal characters apparently are species-specific (pre-epigynes, take notice; this must not inevitably mean that this applies also to the pre-pre-epigynes or other primordial epigynes of instars below subadult females!). Following the studies of (
Somatic characters are not useful for species determination in Fecenia. Colouration and spination, for example, are highly variable intraspecifically. Figures 69 and 82 in
In the description of the genus Fecenia above a characteristic aspect of the spination pattern on the tibiae is mentioned. This may be explained by the life style of the pseudo-orbweavers. Fecenia is the only spider genus in which all representatives spend at least 95% of their lifetime in a very narrow enrolled-leaf retreat or cone retreat in early juveniles. In Araneidae there are several genera including species, that have similar lifestyles, e.g. Acusilas, Cyclosa, Neoscona, Araneus, Cyrtophora, also in Theridiidae, e.g. Parasteatoda simulans (Thorell, 1875). In any case, there is no genus in which all representatives use enrolled leaves as a retreat. Furthermore, in representatives of the families mentioned above the leaf-retreat is never as narrow (in relation to body size) as in Fecenia. A pseudo-orbweaver enters its retreat always with its opisthosoma first. The patellae and tibiae have the most intensive contact with the inner walls of the leaf retreat. As the legs are prograde with leg pairs I–II held anteriorly and III–IV posteriorly it becomes obvious that in the first two leg pairs the retrolateral and in the last two leg pairs the prolateral spines on the tibiae would be an impediment while moving inside the retreat. Perhaps in the course of the evolution of this genus, specimens with shorter spines or even no more spines at these respective positions were preferred? Like in Psechrus the patellae completely lack spines (
