New species of Habronattus and Pellenes jumping spiders (Araneae, Salticidae, Harmochirina)

Abstract The harmochirine jumping spiders include the New World Habronattus, notable for their complex courtship displays, and Pellenes, found throughout the Old World and North America. Five new species of Habronattus and one new species of Pellenes are here described from North America: Habronattus aestus, sp. n., Habronattus chamela sp. n., Habronattus empyrus sp. n., Habronattus luminosus sp. n., Habronattus roberti sp. n., and Pellenes canadensis sp. n. For each of the new species, photographs of living specimens are given, as well as notes on habitat. The new subgenus Pellenattus is described for the subgroup of Pellenes restricted to North America, with type species Pellenes peninsularis Emerton, 1925. Species placed in Pellenes (Pellenattus) are Pellenes apacheus Lowrie & Gertsch, 1955, Pellenes canadensis sp. n., Pellenes crandalli Lowrie & Gertsch, 1955, Pellenes dorsalis (Banks, 1898b), Pellenes grammaticus Chamberlin 1925, Pellenes levii Lowrie & Gertsch, 1955, Pellenes limatus Peckham & Peckham, 1901, Pellenes longimanus Emerton, 1913, Pellenes peninsularis Emerton, 1925, Pellenes shoshonensis Gertsch, 1934, and Pellenes washonus Lowrie & Gertsch, 1955. Pellenes wrighti Lowrie & Gertsch, 1955 is synonymized with Pellenes peninsularis. Attention is drawn to an undescribed species of Habronattus from Canada whose only known specimen is apparently lost.


Introduction
The two jumping spider genera Habronattus F.O. Pickard-Cambridge, 1901 andPellenes Simon, 1876 are closely related within the subtribe Harmochirina (Maddison and Hedin 2003a, b;Maddison 2015). While Habronattus species are confined to the Americas (Griswold 1987) and known for their complex courtship ornamentation and behaviour (Peckham and Peckham 1890;Griswold 1987;Elias et al. 2003Elias et al. , 2012, Pellenes are distributed throughout the Old World, along with North America, and show considerably less sexual dimorphism and courtship complexity. The phylogeny of Habronattus has been studied by both morphological (Griswold 1987) and molecular data (Maddison and Hedin 2003b), but many ambiguities remain -thus, an ongoing phylogenetic study seeks to use genomic data. To offer names for 6 taxa used in that phylogenomic study, five new species of Habronattus and one new species of Pellenes are described from North America. In addition, a new subgenus is erected to house the North American group of Pellenes.

Methods
Specimens are deposited in the Spencer Entomological Museum of the University of British Columbia (UBC-SEM), the Colección Nacional de Arácnidos, Instituto de Biología, Universidad Nacional Autónoma de México (CNAN-IBUNAM), the Museum of Comparative Zoology, Harvard University (MCZ), or the American Museum of Natural History (AMNH).
Preserved specimens were examined under both dissecting microscopes and a compound microscope with reflected light. Drawings (except that of Pellenes peninsularis habitus and palpi from Ontario) were made with a drawing tube on a Nikon ME600L compound microscope.
Terminology is standard for Araneae. The descriptions were written with primary reference to the focal specimen indicated, which was used for measurements and carefully checked for details, but they apply as far as known to the other specimens examined. All measurements are given in millimeters. Carapace length was measured from the base of the anterior median eyes not including the lenses to the rear margin of the carapace medially; abdomen length to the end of the anal tubercle. Rotation of the bulb of the palp expressed in degrees counterclockwise from distal. Thus, 0° is distal (12:00 on an analog clock face); 90° is prolateral (9:00); 180° is proximal (6:00); 270° is retrolateral (3:00). The following abbreviations are used: AME, anterior median eyes; ALE, anterior lateral eyes; PLE, posterior lateral eyes; PME, posterior median eyes (the "small eyes"); RTA, retrolateral tibial apophysis. The apophysis accompanying the embolus of the male palp was called the conductor by Lowrie and Gertsch (1955), the tegular apophysis by Griswold (1987), and the compound terminal apophysis by Logunov et al. (1999). It is here called the "terminal apophysis", abbreviated "TmA", following Edwards (2015).

Genus Habronattus F. O. Pickard-Cambridge, 1901
Type species. Habrocestum mexicanum Peckham & Peckham, 1896 Notes. Most of the approximately 100 species (Griswold, 1987) of Habronattus are found in Mexico and the United States, extending into arctic Canada and to southern South America. Habronattus as a whole is easily recognized by the 90° bend ("elbow") on the long thin TmA of the palp, though the elbow is lost secondarily in the H. coecatus species group. Several clades of species are recognized as species groups (Griswold 1987;Maddison and Hedin 2003b), some referred to here in the descriptions.
Two of the new species were studied by Maddison and Hedin (2003b): H. chamela, called "H. sp. (CHMLA)" by Maddison & Hedin, and H. roberti, called "H. sp. (ROBRT)". For the other new species we used informal names in field and lab notebooks: H. aestus as "peñasco" or "ESTU", H. empyrus as "blondie" or "BLNDI", H. luminosus as "sunglow" or "SUNGL", and P. canadensis as "P. cf. levii". Images and mentions of H. luminosus have appeared on news reports in connection with Zurek et al.'s (2015) study of colour vision, under the name "Habronattus sunglow". Etymology. From the Latin, in reference to the tides and the heat of its habitat. Diagnosis. This species can be placed in the americanus group by male ornamentation (shelf of projecting setae under the AME, Fig. 7; darkened first tarsus, Fig. 6) and the relatively short and pointed terminal apophysis (TmA) arising at about 120°. However, unlike other members of the group (Griswold 1987, figures 184-186), the TmA of H. aestus is thin at the base (Fig. 1), more or less lacking the elbow typical of Habronattus. The male's scantiness of ornamentation is also distinctive -the first males found were not recognized as adult initially -as is the habitat of saline negative estuaries. Both male and female have the first tibia reddish brown, contrasting against a darker patella (Figs 6 and 9).

Habronattus aestus
Description. Male (focal specimen: holotype). Carapace length 1.9; abdomen length 1.8. Palp (Figs 1-2 TmA thin and with only a hint of an elbow. RTA triangular. First leg with tarsus and metatarsus thicker than usual. Colour: Chelicerae pale, covered with erect white setae. Palp femur, patella, tibia with partially erect white setae, especially long prolaterally. Distal 3/4 of cymbium with fine dark hairs. Legs light to medium brown in alcohol, though darker in life. First leg metatarsus and tarsus dark, with extended dark scopula. Clypeus covered with cream coloured scales, with prominent row of long cream-coloured setae extending forward, forming a shelf (Fig. 7). Carapace dark brown with bronze scales. Abdomen similar to that of the juvenile in Fig. 12, reddish brown with broad paler basal band, two distinctive cream triangles centrally, and lateral cream bands made of paired crescents.
Female (focal specimen: paratype, specimen from Estero Cerro Prieto, Figs 3-4). Carapace length 2.3; abdomen length 3.0. Epigynum with semicircular atria; central pocket broad posteriorly (Fig. 3). Colour: Chelicerae medium brown. Legs medium to pale brown, the first pair darkest. Clypeus covered with white scales, with (as in male) shelf of long white setae projecting forward (Fig. 10). Carapace and abdomen covered with cream-coloured scales except for orange-tan patches on abdomen. Central pale triangles (chevrons) on dorsum connected to lateral bands, as in Figs 8 and 10.
Additional material examined. Two juveniles and 3 females from the type locality. Natural history. Found only in the negative tidal estuaries of Sonora, México. These unusual habitats have salt-tolerant plants (such as Salicornia) on soil that is constantly wet with salt water, as the tides enter then drain to cut stream-like channels . Fresh water is rarely available in this harsh desert. Although H. aestus was found at Estero Morúa, in 2013 it was considerably more common at Estero Cerro Prieta. There, it was found either in retreats in the larger salt-tolerant plants along the edges of the channels, about 20-40 cm above the substrate, or on the mud/sand of the slopes of these channels after shaking the overhanging salt-tolerant plants. The courtship involves behaviours similar to those seen in other americanus-group members, though of weak amplitude. A video of the courtship of male AZS13-7854 is available at https://youtu.be/JUkULLdOZ0w.  Fig. 19 in UBC-SEM, 1♀ in MCZ).

Habronattus chamela
Etymology. The name of the type locality is placed as a noun in apposition.
Diagnosis. This little-ornamented species appears to be close to H. nahuatlanus Griswold 1987. The male's white clypeus is divided by one or two central dark bands beneath and between the AME (Figs 18,19,21), separating it from most other Habronattus except H. nahuatlanus and H. banksi (Peckham & Peckham, 1901), from which it differs in having a much less rotated bulb of the palp. In some specimens of H. chamela, the dividing bands are absent (Fig. 20). The bulb of the palp is unusually little rotated (Fig. 13), with the base of the TmA pointing prolaterally (to 90°) as in H. paratus, H. moratus, and the americanus group, from which H. chamela differs in many aspects of markings and form.
Description. Male (focal specimen: holotype). Carapace length 2.0; abdomen length 1.8. Palp with bulb little rotated, with embolus arising at 150° and the base of TmA directed prolaterally (Fig. 13). RTA long with fingerlike projection (Fig. 14). Colour : Chelicerae dark with a patch of white scales . Palp femur and patella pale yellow, contrasting against dark tibia and cymbium. Femora of legs pale centrally, with black annulae proximally and distally. Other segments medium brown (with cream scales) with black annulae distally. Prolateral side of first tibia and metatarsus black. Clypeus covered with white scales except for two vertical black lines near the midline. Extending from clypeus is a broad marginal band of white scales, reaching to the back of the carapace where it contacts the narrow longitudinal bands descending from just inside the PME. Carapace otherwise mostly black or dark brown, except for faint inverted "V" between PME and two small spots in the middle of the ocular area (Fig. 17). Abdomen dark above with a cream sword-shaped longitudinal band along the midline, and with lateral cream lines. The dark areas are black in the anterior third, but reddish in the posterior two-thirds.
Female (focal specimen: paratype, specimen JAL14-9844, Fig. 23). Carapace length 2.1; abdomen length 2.7. Epigynum with central pocket long (Fig. 15); atria separate, not joined anteriorly. Colour: Chelicerae dark with a few white scales on basal half. Legs medium brown but with distinctly paler area centrally on femora. Clypeus dark except for white scales along the margin, extending upward at the midline. Carapace and abdomen as in the male but with lower contrast. The central longitudinal band of the abdominal dorsum is usually broken into two cream-coloured spots.
Geographical variation. Males from the area of El Tuito, north of the type locality, have a continuous red patch in the centre of the clypeus (Fig. 21), instead of two vertical lines. Natural history. Known from the tropical deciduous forests along the southern coast of Jalisco, México (Fig. 101), typically found on leaf litter or sticks on the ground that receives sun but is somewhat shaded (Fig. 99) -in contrast to the more open sunny ground on which H. roberti lives nearby. The courtship involves the male standing at a distance from the female with first legs spread; he walks in bursts toward the female, sidling somewhat. On each burst forward, the front legs are flicked upward and the palps lowered to expose the face. A video of male courtship is available at https:// youtu.be/mgXhB61u0mA. Etymology. From the Greek empyros, burning, referring to the male's flaming colors: a brilliant red face against a pale yellow-orange body and legs. Also, to the author's synesthesia, the dominant letters of the name match the colours of males perfectly: "e" for the green first legs, "r" for the red face, and "y" and "s" for the pale yellow-orange of the body and legs.

Habronattus empyrus
Diagnosis. A member of the coecatus group distinctive for its pale colours. The male's red face and form of the third legs 33,34) distinguish it from all other members of the coecatus group except H. pyrrithrix, from which it differs in having a much paler body, the green first legs paler in life, and the red facial band narrower. The third leg is much like that of H. pyrrithrix, H. carpus and H. mexicanus, with an orange tuft on the dorsal distal side of the femur and a dark patella with pale speckles, a bright white dorsal-basal tuft, and a moderate but thin thumb-like dorsaldistal apophysis (Figs 29-31; compare to Griswold 1987 figures 84-85). However, the femur of H. empyrus has an additional black streak just ventral to the prominent macroseta on the prolateral distal face of the femur (Fig. 29). Typical H. pyrrithrix were found only 6 km away from the type locality, lessening concerns that H. empyrus might be a only a geographical variant.
Description. Male (focal specimen: holotype). Carapace length 2.2; abdomen length 2.1. Palp typical for coecatus group, with sickle-shaped TmA. Embolus arises at 180° (Fig. 26). Colour and ornaments in alcohol: Chelicerae dark at base, paler at tips. Palp femur and tibia pale except dark patch prolaterally and ventrally. Cymbium pale yellow-brown with long white hairs. Legs pale yellowish except for dorsal black stripe on first femur and markings of third leg. First leg with fringes and modified spatulate setae typical of coecatus group. Third femur with longitudinal black lines on dorsal and ventral edges of prolateral face, up to the expanded distal area which bears two black spots and a dorsal tuft of orange setae (Figs 29,30). Third patella with a typical expanded triangular ridge above and a thumb-like apophysis distally. Clypeus red, transitioning abruptly to black between the AME and ALE. The black is a fairly narrow region beneath the ALE. Otherwise, the carapace is covered fairly uniformly with cream to light yellowish-brown scales, with the usual coecatus-group markings indistinct. Abdomen with standard coecatus-group markings of a central pale chevroned longitudinal band with a transverse band cutting across it, but less distinct than usual, because the background is light brown rather than black. In life (Figs 30-34), the palp femur is light brown, not red as in H. pyrrithrix. The integument of the first leg is light green. The third tibia is also green.
Female ( Etymology. Latin, "full of light", in reference to the pale coloring of the body, especially in the yellow-white juveniles, as well as to the name of the locality of the first known specimen, Sunglow, Arizona. Diagnosis. A large-bodied species, covered extensively with pale scales in both males and females. The male is distinctive for the red face with a blue central patch (Figs 43, 46), though in alcohol the blue patch appears as metallic green. The tibial apophysis of the palp has a distinct bump projecting retrolaterally, proximal from the tip (Figs 38, 39). The epigynum is distinctive, with the central pocket for the RTA very small, on a mound in front of which the openings are adpressed (Fig. 40).
Description. Male (focal specimen: holotype, Figs 41-43). Carapace length 3.1; abdomen length 3.2. Palp (Figs 38-39): bulb moderately rotated, with embolus arising at about 290°. RTA with a notable bump dorsally near the tip. Legs: unornamented, as in the female. Carapace: At the back of the carapace is a small stridulatory file, as is seen in various Habronattus species (Maddison and Stratton 1988). The file is similar in form to that of the H. agilis species group, but much narrower. Colour in alcohol: Chelicerae brown with fine glistening hairs. Palp femur light brown with some white scales; tibia with white scales; cymbium brown with a few pale setae. Legs without distinct markings, light to medium brown, with pale scales. Clypeus brown, with a central patch just over the chelicerae of metallic green setae -this contrasts with the appearance in life of a rust-coloured clypeus with a central blue patch (Figs 43, 46). Carapace dark brown with patches of cream-coloured scales in the ocular area, below the PLE, and on the thorax (Figs 41-42, 44). Abdomen dark brown above with a longitudinal band of cream scales medially, wider at front. Sides also covered in cream scales. Venter medium gray-brown.
Female (focal specimen: paratype, specimen . This is the most intact female, as specimen AZS13-7081 (= genetic voucher GLR218) was mostly consumed for RNA extraction. However, an acrocerid fly from ASZ13-7108 emerged about 7 weeks after capture, and thus the abdomen is collapsed. While acrocerid parasitism can affect development, the epigynum of the parasitized specimen (Fig. 40) is apparently natural, as it matches closely to that of AZS13-7081. Carapace length 3.1. Epigynum (Fig. 40) with very small central pocket (the guide for the RTA) embedded within a sclerotized mound. Openings just in front of this mound, almost hidden by it. Colour: Markings indistinct; appendages and body pale yellowish to medium brown, darkest in the ocular area, covered with cream-coloured scales. Abdomen with hint of markings of male (Fig. 48). Clypeus (Fig. 47)  Natural history. After this species was first found by Barbara and Vince Roth in the Chiricahua Mountains in 1977, it went uncollected for many years, despite my many attempts to find it in southern Arizona when I resided there for 13 years. It was then rediscovered in 2012 by Madeline Girard in the high desert scrub/grassland just below the oak woodlands in the Santa Rita Mountains. Subsequent collecting has revealed an unusual habitat: it is found hidden in tall clumps of grass in the desert scrub near the lower edge of the oak woodlands (Figs 102-103). It can be found by lifting up the overhanging grass of the clump, or pushing apart the clump to reveal specimens hidden near its core. Although we did not find many adults in August, small yellowish juveniles with prominent black spots (Fig. 49) were reasonably common. A few were raised for several moults, and by their change in markings, they do appear to be H. luminosus, supported also by the fact that they cannot be assigned to any other known Habronattus in the relatively well-known fauna of southern Arizona. Given the known localities and grassy habitat, its range might be expected to extend into the Chihuahan Desert grasslands. Etymology. Named after my late father, Robert John Maddison, who introduced me to the small things in nature through fishing bait and saturniid cocoons. When my brother and I developed interests in beetles and spiders, he offered to take the family on long collecting trips. His gentle encouragement let me find my own love for the riches of biodiversity.

Habronattus roberti
Diagnosis. Belonging within the clade whose males have modified first and third legs (coecatus, viridipes and clypeatus groups), but not clearly belonging to any of the subgroups. Shows similarities to the viridipes species group (a ridge of raised scales between the PLE; courtship behaviour) but also to the clypeatus group (red-purple third patella; checkered or striped pattern visible in male AMEs). Unlike relatives with green legs, the yellow-green of the first leg of northern populations is weakly green and is restricted to the underside of the femur. Modifications of the third patella are small, in that respect resembling several species of the viridipes and clypeatus groups, but differing from those in having two small bumps dorsally on the patella (Figs 59-60, 67-68). Like H. moratus (Gertsch & Mulaik, 1936), the raised ridge of scales between the PME appears from in front as a tuft over the PME (white arrow Fig. 66) and a broader raised ridge that is bimodal (lower at the midline; black arrow Fig. 66). Unlike H. moratus, the palp's bulb is reasonably well rotated (H. moratus, TmA base pointing to 90°; H. roberti, TmA base pointing to 190°).
Description. Male (focal specimen: holotype). Carapace length 2.3; abdomen length 2.3. Palp's bulb well rotated, with embolus arising at 310° (Fig. 50). Tip of RTA in ventral view curves toward the prolateral, forming a hook, like that seen in H. arcalorus Maddison & Maddison, 2016 and other clypeatus-group members. In retrolateral view, the RTA is more robust than usually seen in the viridipes group. Colour: Chelicerae light brown with a glabrous black patch in basal prolateral portion (Fig. 58). Palp femur pale brown with white setae distally; patella covered with white setae; tibia darker but with long white setae retrolaterally; cymbium covered with white setae. First leg with long fringe of white setae on ventral-retrolateral edge, longest distally; weak fringe ventrally and retrolaterally on patella and tibia; no prolateral fringe. One prolateral macroseta on tibia longer than usual, and only very slightly flattened. First leg black above, brown otherwise, palest beneath the femur where it is covered with white setae expanded at the tip (Figs 57-58). (In life, the integument of the femur shows no obvious green.) Other legs medium to dark brown with cream coloured scales. Second leg with prolateral side distinctly darker. Third femur with faint transverse bands of cream scales as in viridipes and clypeatus group (Fig. 56). Patella with a black spot on the prolateral side, and two protuberances dorsally, red-purple in life (Figs 59-60). (In some speci- mens, the proximal half of the patella is yellowish-green, Fig. 69.) The prolateral face of the tibia has a narrow strongly white band proximally, then a black region, then a rising band of cream scales. Clypeus and sides of carapace brown. Ocular area dark, covered in grey-brown scales that grade to black between the PME. On the thorax, broad bands of cream scales extend from beneath PME and PLE to the posterior margin; these two bands are contiguous with the inverted V of cream scales between the PME. The integument underlying these thoracic bands is pale. Abdomen black to dark brown above with a broad cream basal band, and a central longitudinal band that is widest at front, sometimes contacting the basal band (Fig. 54). Venter with three longitudinal dark bands.
Female (focal specimen: paratype, specimen JAL14-9239, Figs 61, 62). Carapace length 2.3; abdomen length 2.4. Epigynum (Fig. 52) with central pocket parallelsided, as typical for clypeatus and viridipes groups. Atrium small, crescent shaped, in front of a central pocket that has more or less parallel sides. Colour (Figs 61-62) pale except for dark patches on chelicerae in the same places as male. In alcohol there is a faint hint of the abdominal markings of the male.
Geographical variation. Males from the coast of Jalisco, including the type locality and El Tuito, have brown faces (Fig. 58) and a third patella with a red-purple protuberance (Fig. 59). Males from north of the coastal mountain range, near El Grullo, have white hairs on the chelicerae and the border of the clypeus (Fig. 63), a third patella with no black spot and reduced protuberances that lack the red-purple colour (Fig  68), and a first femur that is more obviously greenish (Fig. 63). Males from further north, in Nayarit, have an extensively white clypeus, a greenish first femur (Fig. 64), and a third patella with the black spot and protuberances that are black rather than red-purple. No difference was noted in the palpi, nor were striking differences noted in Natural history. Collected in the tropical deciduous forests in Jalisco and Nayarit, México. It occurs on leaf litter (Fig. 100) along trails and small clearings (Fig 101), exposed to the sun but with shade nearby. Courtship resembles that of the viridipes group, with an early stage in which the palps are waved in small circles and the first leg tips pointed at the female, followed by two transitional waves of the front leg, followed by a long period of asymmetrical flickers of the first legs. Coastal and Nayarit populations have similar displays (Coastal: ♂w259 https://youtu.be/rL24mLEkUxE, ♂w257 https://youtu.be/ty6p7NioFnU; Nayarit: ♂w261 https://youtu.be/i79aw5ju1EA, ♂w262 https://youtu.be/JV8AjMAgO58).
The pattern of light and dark spots or bands visible inside the male's AME (Fig. 69) is an intriguing feature of H. roberti and members of the clypeatus group. Maddison and Maddison (2016) discussed such visible patterns in the male eye as characteristic of the clypeatus group ( Fig. 70; see also https://www.youtube.com/watch?v=Dq5ky7vjPYo). As one looks into the AME of most living salticids with translucent carapaces, one sees the colour changing from honey to black smoothly as the eye moves inside the prosoma and our line of sight moves from the side walls of the eye to the retina itself. The pattern of dark spots in H. roberti and the clypeatus group is therefore unusual. It is unclear whether other Habronattus have such a pattern; the eye simply appears dark.
In H. roberti, as in the clypeatus group, the integument underlying the thoracic bands is unusually pale, which may permit light to enter the prosoma thus revealing the pattern. Given that this pattern is at the same focal plane as the ornamented third legs (Figs 69, 70), it is conceivable that the visibility of the eye pattern itself is a courtship ornament, enabled by the depigmented thorax. Fig. 71 Note. At the Royal Ontario Museum in 1978 I saw a male specimen of Habronattus from Lake Temagami, Ontario, from whose label I recorded the collecting data "Ontario: Temagami. Island 1027. 24 June 1939. #5669", although the museum reference notes indicated the date as 27 June 1937. It was notable for the brush of longer setae on the dorsal distal surface of the cymbium, and the twisted and tufted tarsus of the first leg. In both of these features it resembled the two described species H. carolinensis (Peckham & Peckham, 1901) (from the southeastern U.S.) and H. venatoris Griswold, 1987 (from the southern Rocky Mountains of Wyoming, Colorado, and New Mexico), both of which are notable for the twisted and tufted tarsus and metatarsus of the first leg (Chamberlin and Ivie 1944, figure 210). I drew the palp (Fig. 71), which differs distinctly in rotation of the bulb from those two species (embolus arising at 225°, compared to 270° for H. venatoris and 290° for H. carolinensis), and thus represents a new species. I did not draw the cymbial brush or the first leg, and my memory does not retain their details except that there was a clear resemblance to H. carolinensis in these ornaments. Recent attempts to locate the specimen at the museum have failed, and it may have been loaned for a project on Pellenes (which was never completed) and not returned. In 1995 I travelled to the exact island in Lake Temagami on the label, but no specimens were found. However, the island was rock of perhaps 5 meters by 2 meters, unlikely to sustain any permanent population, and so either the specimen bal- looned in, or the label was incorrect. We are thus left with a biogeographically puzzling new species with no specimen on which to describe it. Two possible habitats might be productively searched: the rock outcrops of the Canadian Shield, or exposed sand of glacial deposits in Northern Ontario and Québec.

Genus Pellenes Simon, 1876
Type species. Aranea tripunctata Walckenaer, 1802 Notes. Currently 84 species are assigned to Pellenes (World Spider Catalog, 2016). There are five subgenera: the nominate, three described by described by Logunov et al. (1999) and one by Prószyński (2016). These are: Pellenes Simon 1876. Logunov et al. (1999) included three species in the nominate subgenus. The TmA is massive, much larger than the embolus. Logunov et al (1999) diagnosed Pellenes s. str. by "a raised epigynal median septum in females ... and the tibial apophysis appressed in the cymbial groove in males".
Pelpaucus Logunov, Marusik & Rakov, 1999(type species Pellenes limbatus Kulczyński, 1895. Six species are assigned to Pelpaucus. Their TmA is a more or less straight flat blade, wide especially at the tip, parallel to the embolus and as long as it. Logunov et al (1999) diagnosed Pelpaucus by the RTA very short or absent, an apical spine on the TmA, a recessed epigynal atrium, and a one-chambered spermatheca.
Pelmultus Logunov, Marusik & Rakov, 1999(type species Attus geniculatus Simon, 1868. Twenty-three species are assigned to Pelmultus. They are compact-bodied (not elongate), with contrasting markings and a somewhat-ornamented male first leg, resembling in habitus to some extent the Habronattus dorotheae species group. The TmA is as long as the embolus but wider, with a complex pointed tip. Logunov et al (1999) diagnosed Pelmultus by the heavily sclerotized epigynal flaps and the subparallel tips of the embolus and the TmA.
Pelmirus Logunov, Marusik & Rakov, 1999(type species Pellenes dilutus Logunov, 1995. Four species are assigned to Pelmirus, having a large complex TmA that curls distally at the tip, like a tongue. Logunov et al. (1999) diagnosed Pelmirus by the embolus and TmA perpendicularly orientated to each other and the peculiar elevated central pocket of the epigynum.
Pellap Prószyński, 2016 (type species implied to be Pellenes lapponicus Sundevall 1833). P. lapponicus has a long embolus and TmA, the latter much wider. Prószyński (2016) characterizes Pellap by the long needle-like embolus sheathed in the thick TmA, trapezoidal RTA, medial groove behind the central pocket of the epigynum, and spiral spermathecae.
In all of these subgenera, the TmA is distinctly larger than the embolus. Many other species of Pellenes are not yet assigned to a subgenus, including many African species whose TmAs are small or (apparently) absent.
Although two Holarctic species are known from the Americas, P. (Pellap) lapponicus and P. (Pelpaucus) ignifrons (Grube, 1861), the remaining species of New World Pellenes form a distinctive group not known to occur in the Old World. The subgenus Pellenattus is here described to contain them.
Pellenattus subgen. n. http://zoobank.org/18078E5C-998D-4498-8D42-86536F0D6FF7 Figs 72-94 Type species. Pellenes peninsularis Emerton, 1925 Diagnosis. Differs from the other described subgenera of Pellenes in having the TmA smaller than the embolus. The TmA of Pellenattus is often reduced to a small protuberance (Figs 72,73,75,77,P. peninsularis), or if as long as the embolus, then it is narrower than it (Fig. 86, P. canadensis). In Old World species placed in described subgenera, the TmA is distinctly broader and larger than the embolus proper. The breadth of their TmA could be considered a synapomorphy of the four described subgenera, thereby excluding Pellenattus. Alternatively, the narrowness of the TmA in Pellenattus could be considered a synapomorphy with Habronattus. Those Old World species with a small TmA are primarily African (e.g., P. bulawayoensis Wesołowska, 1999) and as yet unplaced to subgenus. Pellenattus species have a relatively narrow body and a simple medial longitudinal band, often divided into chevrons, on the abdomen (Figs 82-85), in contrast to Pelmultus and the African Pellenes which are more compact-bodied and have more contrasting markings. Strong transverse or oblique pale abdominal bands as seen in many Old World species (e.g., P. tripunctatus, P. bulawayoensis, P. nigociliatus (Simon, 1875)) are absent from the American species. Molecular data currently being prepared for publication also support the distinctiveness of the American Pellenes.
Most of the described species of Pellenes (Pellenattus) were figured by Lowrie and Gertsch (1955). I have examined the holotypes of those species marked with ! in the list above. Although Griswold (1987) considered P. dorsalis to be a nomen dubium, Banks's figure of the palp almost certainly shows a Pellenes near P. washonus, given the context of the Sonoran fauna. The figure of P. cinctipes Banks, 1898 suggests it belongs here as well. Logunov et al. (1999) placed one of these species within one of the Old World subgenera, P. limatus into Pelmultus, but P. limatus is a typical American species, differing from Pelmultus by the characters mentioned above.

Pellenes peninsularis Emerton, 1925 ] sp. nov. ♂ ♀ ♀ from Ind. Porter Co., Tremont. 8 June 1929". The second (contradictory) locality label matches that expected for the female allotype of P. wrighti, and may have been inserted or retained in error. Lowrie and Gertsch (1955) compared P. wrighti to P. apacheus but made no comment about its differences from P. peninsularis, despite the P. wrighti holotype having been originally identified as P. peninsularis. The holotypes of P. peninsularis and P. wrighti and other specimens from throughout the range bear no known features that would justify distinguishing two species. The bodies of specimens from Ontario and Nova Scotia are primarily black; those from the prairies of Minnesota, Montana and South Dakota are dusted with tan to orange scales, corresponding to their different substrates (dark rock outcrops in the eastern Canadian populations; prairies further west). There may be a small genitalic difference, in the size of the dorsal lobe of the cymbium, which appears to be larger in eastern than western populations (Figs 76, 78 versus Fig. 74). However, any difference would be slight, within the usual variability of a single species, and there is no indication of an abrupt transition in form in specimens arrayed from Nova Scotia through Montana. Otherwise, the male palp is consistent Natural history. Collected at fairly high elevation on open ground with scattered small rocks, sticks and sparse vegetation (Fig. 98).
