Etymology. The specific name is a noun in apposition taken from the Kichwa language meaning “pointed”.
Diagnosis. Males and females can be distinguished by their pointed abdomen (Figs 35, 54, 55). Furthermore, males are easily distinguished from all species by their long embolus (Fig. 30); from Anapis chiriboga males are distinguished by their shorter embolus (± 2x the length of palpal bulb) and with one basal loop (Fig. 30, 54), whereas the embolus is ḵ 2x the length of the palpal bulb and with two loops in A. chiriboga (Platnick & Shadab, 1978; fig. 24; Fig. 58). Females can be distinguished from A. calima with similar triangular abdomen, by their wide and transparent copulatory ducts with two loops (Fig. 36), narrow and with one loop in the latter species (Platnick & Shadab, 1978; fig. 52).
Description. Male (holotype): Total length: 1.46; carapace length: 0.51; carapace width: 0.46; abdomen length: 0.95; abdomen width: 0.78; clypeus height: 0 19. Cephalothorax: Carapace orange; pars cephalica punctated with gray markings on dorsal surface and about the eye; cephalic groove punctated; pars thoracica punctated laterally, granulated dorsally (Fig. 54). Sternum orange-brown, suffused with dark gray, deeply punctated, longer than wide, covered with setae. Labral spur present. Clypeus orange-brown and punctated. Chelicerae orangebrown, punctated, excavated medially with one basal, one apical tooth and denticulate plate apically (Fig. 32). Eyes: 6 eyes, rounded; AME absent, ALE contiguous, ALE-PLE contiguous, LE-PME contiguous, PME contiguous. Abdomen: Pointed apically with orange dorsal scutum; dorsal soft portion with small, rounded setose sclerites; laterally suffused with 5–6 stripes of dark gray, alternating with rows of elongated non-setose sclerites (Fig. 54); spinneret scutum complete. Legs: Orange; metatarsus I without cusps, tarsus I with one prolateral cusp (Fig. 33); metatarsus II and tarsus II without cusp (Fig. 34). Genitalia: Palpal patella with small ventrally curved retrolateral apophysis; tibia without trichobothrium, elongated, pointed retrolateral apophysis (Fig. 30). Cymbium cup-shaped, excavated prolaterally (Fig. 31). Embolus and conductor long and sinuous with one basal loop, conductor very faintly ridged apically (Figs 30, 31, 31a).
Female (paratype): Total length: 1.86; carapace length: 0.65; carapace width: 0.55; abdomen length: 1.21; abdomen width: 0.92; clypeus height: 0.11. Cephalothorax: Same coloration and pattern of punctation as male (Figs 35, 55). Chelicerae and sternum as male. Labral spur present. Eyes: 6 eyes, rounded; AME absent, ALE separated by 1/4 their diameter, ALE-PLE contiguous, LE-PME separated by their diameter, PME contiguous. Abdomen: Pointed apically, uniformly light to dark gray without scutum, with white mark dorsally; numerous setose sclerites dorsally; laterally with rows of non-setose sclerites (Figs 35, 55); spinneret scutum complete. Legs: Orange; metatarsus and tarsus I with one cusp; metatarsus and tarsus II without cusps. Genitalia: Ventral scutum bright orange, visible through the scutum: a pair of rounded spermathecae and rounded copulatory openings separated by their diameter (Fig. 36). Internal genitalia with large and transparent copulatory ducts, narrowing gradually, ending with two loops; spermathecae rounded; fertilization ducts long, directed basally (Fig. 37).
Distribution. Ecuador: Cotopaxi and Santo Domingo de los Tsáchilas Provinces.
Natural history. Most specimens were collected by pitfall trap between 1,209–1,800m, from May to August.
