Diagnosis

Anapistula delrosalae sp. nov. can be distinguished from the females of other species in the genus by the following combination of characters: robust conical denticles in cheliceral furrow ( Fig. 2 View FIGURE 2–5 ), a serrated fang ridge ( Fig. 2 View FIGURE 2–5 ), one dorsal trichobothrium on the tibia ( Fig. 3 View FIGURE 2–5 ), a distal lyriform organ on the dorsal side of the metatarsi ( Fig. 4 View FIGURE 2–5 ), a triangular-shaped epigynal atrium over the ducts area, and an internal copulatory organ with a bowling pin-shaped median duct MD, two tiny LD, and two larger circular spermathecae ( Fig. 5 View FIGURE 2–5 ). The other species present in Europe, A. ataecina , is different to the new species because it has a smooth fang ridge ( Cardoso & Scharff 2009: Figs. 3A–B View FIGURE 2–5 ), one trichobothrium on the patella, and a copulatory area with an elongated and columnar MD, two short LD with similar wide of MD, and proportionally small or medium-sized spermathecae ( Cardoso & Scharff 2009: Figs. 7 View FIGURE 6–15 ). The size differs between the two species, the new species is larger and more translucent than A. ataecina ( Cardoso & Scharff 2009: Figs. 2 A, D–F View FIGURE 2–5 ), which is brown when it is alive ( Fig. 6 View FIGURE 6–15 ).

Etymology: This species is named in honour of Yolanda del Rosal, biologist in the Cave of Nerja Research Institute.

Description

Female

General appearance.Alive specimens pale yellow with prosoma and legs translucid and 2 darker stripes with chevron shape on the posterior side of opisthosoma ( Figs. 6 and 13 View FIGURE 6–15 ). Body and legs of white colour when preserved ( Fig. 7 View FIGURE 6–15 ).

Prosoma. Clypeus high with five–six spiny setae. Four eyes in two groups disposed on each side of frontal area of carapace, one seta in each eye group ( Fig. 8 View FIGURE 6–15 ). Cheliceral furrow with two conical denticles ( Fig. 9 View FIGURE 6–15 ), fang ridge serrated. Maxillae longer than wide with serrula of 14–18 denticles on prolateral side ( Fig.10 View FIGURE 6–15 ). Labium short, widened, curved in its distal zone. Sternum shield-shaped, covered with long setae, posterior area truncated ( Fig. 11 View FIGURE 6–15 ). Legs with one retrolateral rugose area on all femora ( Fig. 12 View FIGURE 6–15 ), one dorsal strong macroseta, one dorsal trichobothrium on tibia, and one dorsal lyriform organ in metatarsi of all legs. Legs formula: Leg I> Leg IV> Leg II> Leg III.

Opisthosoma globular, poorly covered by tiny setae with one chevron of darker colour on its posterior area ( Fig. 6, 7 and 13 View FIGURE 6–15 ). Epigynal area with wide triangle shaped atrium ( Fig. 14 View FIGURE 6–15 ), MD short, wider in the beginning and closer in its distal zone with two short and tiny LD and proportionally big circular sclerotized spermathecae ( Fig. 15 View FIGURE 6–15 ).

Male unknown.
