description
MALE (Holotype): Total length 11; Carapace, long 5; wide 5.87. Carapace anterior part tapering. Eyes. Anterior row slightly procurved, posterior row recurved (Fig. 193 B). Many short bristles between AME-clypeus and one long bristle ALE – PLE. Many short bristles between posterior-fovea and some between lateral eyes-edge of carapace. Sternum with eight sigilla fused medially, two distal sigilla more demarcated than others (Fig. 193 C).

Patellae III and IV with spines on prolaterodorsal face (Fig. 194 A, C). Tibia IV without spines on dorsal surface (Fig. 194 D). Without ventral pseudoscopulae on tarsus I, ventral pseudoscopulae occupying 10 % of length of tarsi I, 30 % of II and 100 % of III and IV. Pseudoscopula of tarsi I and II with setae spaced, forming diffuse group of bristles, on tarsi III and IV, compact.

diagnosis
Diagnosis. Males of Actinopus concinnus resemble those of A. tarsalis (Fig. 9 A – C), A. castelo (Fig. 12 A – C) and A. jamari (Fig. 198 A – C) by the absence of BTA, and those of the group cucutaensis by having an apical tegular process (ATP). They differ from those of all species in the genus by the ATP being inserted obliquely in relation to the embolus, with many cusps covering the ATP surface (Fig. 195 A – C).
distribution
Distribution. VENEZUELA. Bolivar; and Caracas: San Jose del Avila (Map 11).
etymology
Etymology. The specific name is a Latin adjective meaning bizarre, referring to the odd apical tegular process in this species, protruding from the tegulum in a unique way.
