Morocco – Rif Region • 2♂♂, 6♀♀; Faculté des Sciences; 14–28/II/2022; A. Akarid leg; reared from fungus Cyclocybe aegerita; UAE-FST R22/2441.

This species belongs to the Exechia parva Lundström, 1909 group, which was revised by Lindemann et al. (2021). The Moroccan males are similar in structure of their terminalia (Figs 2, 3) to E. repandoides, which is widespread in central and northern Europe and is also recorded from Corsica. These Moroccan males differ in coloration from European specimens, which have the abdomen dark coloured apart from the yellow terminalia. The Moroccan males have the abdomen brown dorsally, but broadly yellow laterally on tergites 2 and 3; sternites 1–3 are yellow, while tergites and sternites 4–6 are brown. The female has not been previously associated for E. repandoides. The Moroccan females are more brightly coloured than European females of this group; the abdomen (Fig. 4) is broadly yellow laterally, with brown dorsal markings on tergites 2–6 often not quite reaching fore margins, while tergite 7, the ovipositor, and all sternites are yellow. New to North Africa.

Genus Rymosia Winnertz, 1864

Holotype. Morocco – Rif Region • ♂ (mounted in DMHF); Forêt Jbel Lekraa; 12/VI/2013; M.J. Ebejer leg; collected using sweep net; NHMUK. Paratypes. Morocco – Rif Region • 1♂; Oued Majjou; 5/II/2019; B. Belqat and O. Driauach leg; collected using sweep net; UAE-FST R19/2425 • 3♂♂; Tissemlal; 3/II/2020; B. Belqat and O. Driauach leg; collected using sweep net; UAE-FST R20/2426 • 1♂; Bab Rouida; 13/II/2020; B. Belqat and O. Driauach leg; collected using sweep net; UAE-FST R202427.

The species has been found mostly in the PNTLS, at high altitudes, in the large expanse of a cedar forest, in the environment of the Majjou River and in/and around the depression in a rock, resembling a small cave in the Bab Rouida site.

This belongs among those Rymosia species without any spinules on the male fore tarsi. It is very distinct from other species in the structure of its male terminalia. The produced apical margin of the gonocoxites, bearing strong apical setae, is an especially unusual feature. This and the gonostylus concealed within the gonocoxites in ventral view distinguish it from the other three Rymosia species recorded from Morocco, R. affinis Winnertz, 1864, R. beaucournui Matile, 1963, and R. pseudocretensis Burghele-Balacesco, 1966 (Banamar et al. 2020).

Male. Wing length 4–4,5 mm. Coloration. Head brown, with face yellowish. Antenna with basal segments and base of first flagellomere yellow, flagellum otherwise brownish. Palpus yellow. Thorax yellowish brown; mesonotum with three more or less fused

brown stripes, leaving humeral area and sides yellowish. Legs all yellow. Wing clear yellowish. Abdomen yellow with apical half of tergites 2–5 brown, each of these markings extended forwards as a dorsal triangle almost reaching fore margin and as a rounded extension laterally on each side; tergite 6 all brown. Terminalia yellow. Head. Antenna longer than head and thorax together, with flagellomeres progressively longer, from 3–4× to 6× as long as broad. Palpus elongate. Thorax. Mesonotum with long, dark setae in dorsocentral rows, near the side margins, and on pronotum; one long dark proepisternal seta; anepisternum covered with short setae; laterotergite with several long setae medially. Legs. Without any modification of tarsi (found in some species of this genus); hind tibial spurs about a third as long as hind tarsomere 1; tibial setae short, not longer than width of tibia. Wing. Vein Sc short, ending free. Crossvein r-m 2–3× as long as stem of median fork. Base of posterior fork at or before level of base of median stem; false vein extends to level of about half length of posterior fork, vein CuP reaches to level of about a third of fork. Terminalia (Figs 5–7). Gonocoxites produced medially with a group of 4 or 5 short but strong spines on each side of a small median emargination, and a row of strong setae on the apical margin external to the spines; gonostylus with ventral lobe short, not extending beyond margin of gonocoxites, rounded and densely setose apically; median and dorsal lobes with long setae basally and an apically bare sclerotised portion adjacent to ventral lobe, dorsal lobe with long basal extension bare except for preapical spine.

This species was collected mostly in environments of aquatic ecosystems such as springs (Aïn) and ponds (Daya), but also in forest environments.

The most obvious differences in the male terminalia from L. bimaculata (Figs 10, 13, 16) are that the apical part of the gonostylus is shorter and thicker, and the adjacent ventral lobe of the gonocoxites is broader basally (arrowed in Fig. 15 of L. arcana and in Fig. 16 of L. bimaculata for comparison). In these respects, L. arcana resembles these structures in the figures of L. montanosilvatica Zaitzev, 1994, described from Kyrgyzstan (Zaitzev 1994). However, L. montanosilvatica is said to have unmarked wings, so L. arcana is considered a distinct species pending further revision of this genus.

Leia beckeri is similar in colour to L. arcana; in examined specimens of L. beckeri, the dark-brown thoracic stripes are more sharply contrasted with the yellow sides and humeral area of the mesonotum than in L. arcana, and the pleura and abdomen are all dark brown. The marking over r-m may sometimes be faint in L. beckeri, but it differs in the preapical wing marking being situated closer to the tip of vein R₁ than in the other Moroccan species and well before the tip of cell r₁. The male terminalia of L. beckeri (Figs 11, 14, 17) are also similar to this group of the genus; the gonostylus is constructed similar to L. bimaculata and L. arcana, with the apical part intermediate in thickness between these species, but there is a slender tapered process ventral and external to the gonostylus (arrowed in Fig. 17), and the ventral lobe of the gonocoxites is broadly rounded and not apically produced as in these other species.

The females of these three species are similar in the structure of the ovipositor (Figs 18–20), but they evidently differ in the form in lateral view of the upper margin of sternite 8, which is more rounded in L. bimaculata, straighter and slightly emarginate in L. arcana, and with a more distinct emargination in L. beckeri.

Male. Wing length 4–4.5 mm. Coloration. Mainly shining black or dark brown with yellow markings. Head black; antenna with scape and pedicel yellow, flagellum dark brown. Mesonotum bearing three almost fused shining dark brown stripes (separated by narrow yellow dorsocentral stripes), leaving the humeral area and sides yellow; scutellum dark brown dorsally, sometimes more or less yellowish at sides; propleura brownish yellow; pleura otherwise and mediotergite all dark brown. Legs yellow except for narrow dark tips to coxae and trochanters and apical eighth of hind femur. Wing clear yellowish except for brown preapical patch that extends from fore margin (including tip of cell r₁) over the median fork. Haltere yellowish white. Abdomen dark brown with hind margins of tergites 2–4 and fore margins (basal third) of tergites 3–5 narrowly yellow; sternites similarly coloured or with more yellow. Terminalia yellow. Head. Antenna about 1.5× as long as head and thorax, with flagellomeres more than 2× as long as broad. Thorax. Mesonotum and scutellum with long yellow setae; laterotergite setose. Legs. Tibiae 2 and 3 with long yellow apical spurs, more than half as long as tarsomere 1; setulae on femora pale, on rest of legs dark; dark tibial setae, mostly longer than width of tibia: mid tibia with 2–3 d, 1 a-d, 3 a, and 2 a-v setae; hind tibia with 3–4 d and 3–4 a-d setae. Wing. Vein Sc ends in costa near to level of base of posterior fork, with crossvein sc-r at about its apical third. Vein R₁ a third to half the length of crossvein r-m, which is longer than the stem of median fork. Median fork complete. Posterior fork arises before level of base of stem of median fork, its anterior branch (M₄) narrowly interrupted at its extreme base. CuP stops short beyond level of base of posterior fork. A short dark streak at base of fork of axillary veins (as in L. bimaculata). Terminalia (Figs 8, 9, 12, 15). Gonostylus comprising a single lobe, curved medially and with a small preapical incision; gonocoxites with a setose ventral lobe basal to each gonostylus that is tapered to a bluntly rounded tip (arrowed in Fig. 15).

From Latin arcanus, meaning secret as the separation of this species was previously hidden.

The male from Aïn El Ma Bared and the female from Azrou were listed under L. bimaculata by Banamar et al. (2020). The female (Fig. 18) is considered conspecific with L. arcana on basis of its coloration.

Genus Megophthalmidia Dziedzicki, 1889

This genus was recognised to have a greater diversity in southern Europe than previously appreciated when six species, five of them newly described, were recorded from Greece by Chandler et al. (2006). Two of these species were recorded from Sardinia by Chandler (2009) and one of them, M. illyrica Chandler, Bechev & Caspers, 2006 is newly recorded here from Gibraltar (Governor’s lookout, Upper Rock, 1♂, 28/II/2010, coll. K. Bensusan and R. Gwillem). As there is also a species of this genus, M. decora (Santos Abreu, 1920), in the Canary Islands and Madeira the occurrence of the genus in Morocco was expected.

Found in environments of protected areas (National Park of Talassemtane and Bouhachem Natural Park Project), around aquatic systems (rivers and ponds) but also in developed as well as inhabited areas.

This species is similar in coloration to M. illyrica, and the male tergite 9 is also similar in form to that species. The structure of the terminalia is otherwise quite distinct with the gonocoxites more deeply excavated ventrally and the gonostylus differing in form, broader basally and more angular apically. Specimens examined vary in the extent to which the gonostylus is extended in situ, giving a differing appearance which might suggest that more than one species is involved but their structural details are in common as described below. To take this apparent variation in form into account three specimens have contributed to the figures as indicated.

Male. Wing about 2 mm. Coloration. Body nearly all black, with yellowish apical margins to tergites 2–4, interrupted dorsally, and there may also be very narrow yellow basal margins to tergites 3–5; sternites 2–4 all yellow. Antenna black. Palpus black at base, otherwise yellow. Legs with mid and hind coxae brownish externally, otherwise all yellow. Wing clear yellowish. Terminalia dark coloured. Head. Antenna a little longer than head and thorax together, with flagellomeres at least as long as broad: flagellomeres 1 and 2 quadrate, other flagellomeres a little longer than broad. Legs. [Only one fore leg, femur, and part of tibia of one mid leg, and both hind legs are present in the holotype; paratypes are all missing one or more legs]. Mid tibia and hind tibia with rows of anterior and dorsal setae, all shorter than tibial width, the dorsal setae on hind tibia denser and occupying most of its length. Tibial spurs 1: 2: 2, yellow, the longer spurs on each about two-thirds length of first tarsomere. Wing. Radial veins and crossvein r-m with setulae, fork veins and their stems bare. Vein R₁ a little longer than r-m, median stem about twice length of r-m. Base of posterior fork level with or just beyond base of stem of median fork, its branches widely divergent from base. Costa extends about 0.6 distance from R₄₊₅ to M₁. Terminalia (Figs 21–26). Small. Tergite 9 comprising apically pointed lateral lobes, connected by a narrow bridge to a prominent bilobed median process bearing cerci; each cercus with a ventrally directed tapered lobe with a row of long setae; gonocoxites with broad and deep medial excavation ventrally, dorsally produced medially on each side into a bifid process (arrowed in Figs 24, 26) with each lobe with a short terminal spine. Gonostylus (arrowed in Figs 25, 26) broad and bare basally, sharply narrowed to an angular apical part bearing some long setae and a short terminal tooth-like spine.

Named for the locality Daya Amsemlil, where both Megophthalmidia species recorded here and the new species of Mycomya described below were collected.

This is evidently a widespread species in Morocco.

This species was described from Greece (Chandler et al. 2006), later recorded from Sardinia (Chandler 2009), and has most recently been identified from Corsica. It is similar in coloration and most structural characters to M. amsemlili and M. illyrica. The terminalia (Figs 27–29) are, however, quite distinct in structure. The antenna is shorter than in M. amsemlili and M. illyrica; the flagellomeres, except the terminal one, are distinctly shorter than broad, and this character also enables females to be separated from those of M. amsemlili and M. illyrica. New to North Africa.

This species inhabits the diverse landscape of the Bouhachem Natural Parc Project, particularly including wetlands, which present a typology from sphagnum peat bogs to temporary ponds to springs, spring streams, and headwaters of three river systems, as well as in forests.

This species belongs to the subgenus Mycomya sensu stricto and differs from other species in the following combination of male characters: legs simple except for short mid-coxal spur; tergite 9 with neither a medial process nor lateral appendages, medially emarginate and with short internal spinose setae subapically. It runs to couplet 75 in the key by Väisänen (1984), where it is between the two options in that the base of the posterior fork is usually level with the base of the stem of the median fork. It fits the first option in the structure of tergite 9 and in couplet 76 it agrees with the western Nearctic M. fuscipalpis van Duzee, 1928 in the form of the gonostylus. Thus, it could be assigned to the species group of which M. fuscipalpis was the only member. The most obvious difference from M. fuscipalpis is that there are separate submedian appendages of the gonocoxites, while in M. fuscipalpis these are fused medially.

Male. Wing length 4–4.5 mm. Coloration. Body entirely dark greyish brown. Head and antennae uniformly dark; palpi yellowish. Coxae brown, legs otherwise entirely yellow. Terminalia dark grey. Head. Antenna slender, about 3 mm long, longer than abdomen, with flagellomeres about 6× as long as broad. Legs. Long and slender. Fore coxa unmodified; mid coxa with anteriorly directed slender spur, straight for most of its length, then slightly curved apically, relatively short, about half length of coxa. Fore tarsomere 1 a little shorter than its tibia. Vein Sc ending in R at middle of radial cell, often with anterior spur, more or less extended to costa (may vary between the wings of a specimen). Base of posterior fork at or just beyond level of base of stem of median fork. Terminalia (Figs 34, 35). Short. Tergite 9 with a median emargination between broad rounded setose lobes, with a pair of internal submedian lobes each bearing a slender curved spine laterally and a row of 5–7 short blunt spines (cones of Väisänen 1984) apically. Gonocoxites with short broad submedian appendages that are bluntly rounded apically. Gonostylus reflexed within gonocoxites, thick and angular basally and sharply narrowed to a slender curved and pointed apical part which has a small blunt tooth at its base.

This is a Holarctic species, which is widespread in Europe. New to North Africa.

Genus Phthinia Winnertz, 1864

This is a small genus, but with a diversity of structure of the male terminalia. Zaitzev (1994) included 10 Palaearctic species, of which four occur in Europe, one (P. hyrcanica Zaitzev, 1984) occurs in Azerbaijan, and the rest live in the Eastern Palaearctic. Three more European species have since been described (Plassmann 1984, 1990; Zaitzev 2001). A male and a female, collected at the same locality in Morocco, have been examined; both specimens are in poor condition, but the structure of the male terminalia is distinct from any previously known species of the genus.

Holotype. Morocco – Rif Region • ♂ (mounted in DMHF, terminalia on slide); Khandek Melouka; 10/IV/2021; B. Belqat and O. Driauach leg; collected using sweep net; NHMUK. Paratype. ♀; same data as for holotype; UAE-FST R21/2424.

The type locality is in the environment (forest and cultivated fields) of Aïn Lahcen, a rural commune whose name (Aïn) is taken from a spring that flows through it.

This is a slender bodied species with small male terminalia, similar in this respect to P. winnertzi Mik, 1869 and allied species. Among Palaearctic species, it most closely resembles P. hyrcanica in the apically bilobed gonostylus situated within the broadly rounded gonocoxites. It differs from that species in the lobes of the gonostylus being short and blunt and in the dense short setae on the margins of the gonocoxites.

Male. Body 7 mm, of which about 6 mm is length of abdomen. Coloration. Head brown. Antenna with short basal segments and base of first flagellomere yellow, remainder brown. Palpi yellow. Thorax yellowish brown, darker brown on disc of mesonotum and scutellum. Legs yellow. Wings clear grey, presumed to be unmarked as in female. Haltere brown. Abdomen entirely dark brown. Terminalia yellow. Head. Both antennae incomplete (11 and 5 flagellomeres present). Legs. Missing apart from one fore femur and one hind leg. Wing. Both wings are represented only by short stubs. Abdomen. Long, slender. Terminalia (Figs 37, 38). Small. Gonocoxites rounded laterally, with deep medial excavation bordered by short, dense setae; gonostylus enclosed by gonocoxites, short and with two short, blunt apical lobes.

Female. Body 6 mm, of which around 5 mm is length of abdomen. Coloration. As in male; wings clear greyish. Ovipositor brownish yellow. Legs. Fore legs missing but mid and hind legs complete, long, slender, about 9 mm long. Wing. Both wings are represented only by stubs, but more of the right wing is present, including the bases of fork veins. Vein Sc ends in costa before level of base of Rs. Crossvein r-m about 3× as long as stem of median fork. Base of posterior fork beyond that of median fork, with posterior branch (vein CuA) downturned; false vein also downturned, parallel with it. Vein CuP stops short before level of base of posterior fork. Abdomen. Slender, relatively shorter than in male. Ovipositor short and small, with cerci short ovoid and covered with short setae.

The name commemorates Snibby Pins, erstwhile companion of Benjamin Bottom, after whom the Sardinian gnat Sciophila benjaminbottomi Chandler, 2009 was named.

This is the first record of this genus from North Africa, and this species is evidently rare. Phthinia species are usually found around rotten wood, and they develop in encrusting fungi.
