Agyneta darrelli Dupérré, 2013, new species

Agyneta darrelli new species Figs 185–194, map 11 Type material: Male holotype from Washington, Friday Harbor, W123.01: N48.28, June-July 1928, Shackleford (AMNH). EXAMINED. Etymology: The specific name is a patronym in honor of Darrell Ubick, curatorial assistant at the California Academy of Sciences, great arachnologist and dear friend. Diagnosis: Males are distinguished from all other Agyneta species by the long hook-shaped lamella characteristica (Fig. 185). Females are distinguished from most species by their abdominal patterns (Fig. 190). From A. fillmorana see diagnosis of the latter and from A. bucklei by the oblique sides of the proximal part of scape (Fig. 191), straignt in the latter (Fig. 206). Description: Male: Total length 2.23; carapace length 0.93, width 0.79. CEPHALOTHORAX: Carapace orange-brown, shiny, finely reticulate; suffused with dark gray along radiating lines and pars cephalica. Clypeus height 3. Sternum completely suffused with dark gray. Chelicerae orange-brown, not excavated; seta-tipped tubercles absent; promargin three denticles, retromargin one small apical denticle. Cheliceral stridulatory organ visible ~14 striae, well spaced followed by 28 closely spaced striae. ABDOMEN: Coloration highly variable; uniformly dark gray or dark gray with some off-white specks or else with dark median band and dark lateral sides (Fig. 189). LEGS: Light yellow-orange; leg I total length: 4.31; leg III total length: 2.87; Tm I: 0.30, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis small, triangular; dorsal tibial apophysis smooth; two retrolateral trichobothria and a dorsal one (Fig. 185). Cymbium with retrolateral fold; glabrous depression present (Fig. 185); dorsal and ventral cymbial tubercles reduced, slightly rugose; prolateral notch absent (Fig. 186). Paracymbium with apical pocket only (Fig. 185). Embolus tip pointed, with a few apical spines; Fickert’s gland absent; ventral lamella spiny apically, serrated basally; thumb going beyond the embolus proper (Fig. 187). Embolus proper set apically, serrated, crest-like extending to the tip of embolus (Fig. 187). Anterior terminal apophysis long and pointed with curved protrusions; posterior terminal apophysis short, with spines basally; lamella characteristica hook-shaped (Fig. 188). Female: Total length 2.31; carapace length 1.06, width 0.81. MAP. 11. Localities of Agyneta darrelli n. sp. and of Agyneta miniata n. sp. CEPHALOTHORAX: Coloration same as male. Chelicerae orange-brown, promargin five denticles, retromargin three apical denticles. Cheliceral stridulatory organ visible ~14 striae, well spaced followed by ~37 striae closely spaced. ABDOMEN: Coloration highly variable; uniformly dark gray or with dark median band and dark sides or else dark gray apically and laterally (Fig. 190). LEGS: Same as male; palpal tarsal claw absent; leg I total length: 4.40; leg III total length: 3.14; Tm I: 0.30, Tm IV: absent. GENITALIA: Epigynum with wide proximal part of scape with slightly oblique sides; epigynal slits oval; pit hook depression shallow (Fig. 191); lateral lobes short and wide; stretcher and pit medium (Fig. 192). Median part of scape elongated and narrow (Fig. 193); genital pores located at base of lateral lobes pockets (Fig. 194). Internal genitalia with rounded receptacula ventrally and a small triangular receptacula dorsally (Figs 192, 193).
