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.
