Andromma aethiopicum Simon, 1893: 390 View in CoL , figs 346–348 (description ♂ ♀).

Diagnosis

Andromma aethiopicum differs from all other known species of Andromma by the complete absence of posterior median eyes in both males and females, by the RTA which is close to that of A. albinovani sp. nov. but differs from it by being bifid in ventral view and hooked in retrolateral view, and by the widely separated transversely oval copulatory openings.

Material examined

Lectotype (here designated)

ETHIOPIA • ♂; Agaos ; M.A. Raffray leg.; MNHN AR1678 About MNHN .

Paralectotype

ETHIOPIA • 1 ♀; same collection data as for lectotype; MNHN AR1678 About MNHN .

Note

Precise date and locality unknown.

Description

The specimens are completely bleached and the description is therefore restricted to some essential details; limits of secondary eyes, chilum, spines and clypeal setae are invisible. The translation of the original Latin description of Simon (1893) and his drawings are provided.

Translation of original description

Cephalothorax yellowish orange, smooth and hairless. Anterior median eyes black, with black margin. Abdomen short, ovate, dorsum pale grey, with many yellowish dots, venter pale with epigastric area yellow, slightly coriaceous. Sternum, mouthparts and legs bright yellow, labium darker. Palp pale yellow with extremities somewhat darker; femur fairly long, narrow and almost straight; patella almost twice as long as wide; tibia slightly shorter than patella, somewhat tapering, provided with a minute distal prolateral tooth and a retrolateral dark, very sharp apophysis, which is hooked at the tip. Ventrally a subspherical apophysis, which is anteriorly concave and ridged. Tarsus longer than tibia plus patella, rounded at base, with tapered, fairly long tip, widely surpassing bulbus.

Female similar to male, but dorsum of abdomen darker. Palp fairly long, tibia much longer than patella, tarsus slightly longer and thicker than tibia. Epigyne a fairly large, transversely oval, reddish and shiny area, on either side with large subcircular shallow depression. Original Latin text: Simon (1893: 390).
