Description: Male : Total length 1.98; carapace length 0.91, width 0.68. MAP. 24. Localities of Agyneta crista n. sp. , Agyneta catalina n. sp. CEPHALOTHORAX: Carapace orange, shiny, finely reticulate; lightly suffused with gray along margin. Sternum suffused with dark gray. Clypeus height 2. Chelicerae light orange, excavated; ~ 25 seta-tipped tubercles present; promargin four denticles, retromargin two tiny denticles. Cheliceral stridulatory organ visible ~56 striae, narrowly spaced throughout. ABDOMEN: Uniformly light to dark gray. LEGS: Light yellow; leg I total length: 3.41; leg III total length: 2.35; Tm I: 0.26, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis long, tip recurved slightly serrated lip; dorsal tibial apophysis wide, smooth; two retrolateral trichobothria and one dorsal ( Fig. 361 ). Cymbium triangular; glabrous depression present ( Fig. 361 ); dorsal cymbial tubercle with rounded tip and carinated; ventral cymbial tubercle long, smooth with rounded tip; prolateral notch shallow ( Fig. 362 ). Paracymbium apical pocket medium, anterior pocket long making a large cover, posterior pocket absent ( Fig. 361 ). Embolus tip wide and pointed, with wide and dentate prong; ventrally rugose; Fickert’s gland absent; ventral lamella transparent, spiny; thumb reaching embolus proper ( Fig. 363 ). Embolus proper set apically, dorsal part slightly larger ( Fig. 363 ). Anterior terminal apophysis very wide with numerous protrusions; posterior terminal apophysis with narrow pointed tip and one spur-like process basally ( Fig. 364 arrow); lamella characteristica wide, well sclerotized with pointed tip ( Fig. 364 ). Female : Total length 1.74; carapace length 0.75, width 0.57. CEPHALOTHORAX: Coloration as male. Clypeus height 2. Chelicerae orange, promargin five teeth, retromargin five denticles. Cheliceral stridulatory organ visible ~52 striae, narrowly spaced throughout. ABDOMEN: Same as male. LEGS: Same as in male; palpal segment slightly suffused with gray, tarsal claw absent; leg I total length: 2.87; leg III total length: 2.03; Tm I: 0.29, Tm IV: absent. GENITALIA: Epigynum with wide proximal part of scape, slightly enlarging; epigynal slits narrow and triangular; pit hook depression indistinguishable ( Fig. 365 ); lateral lobes short; stretcher short; pit deep ( Fig. 366 ). Median part of scape long and narrow, wrinkled; genital pores situated at lateral lobes pockets ( Fig. 367 ). Internal genitalia with large pear-shaped receptacula ( Figs 366, 367 ).
