(Figs 38–46)

Acrotaphus chedelae Gauld, 1991: 327 . Holotype ♀ [#CRI001 101687], Costa Rica (MNCR) [examined by digital image].

Diagnosis. This species can be distinguished from all other species of Acrotaphus by the combination of the following characters: 1) margin of gena behind eyes flat in dorsal view; 2) margin of gena 0.75–0.95× length of eye in dorsal view; 3) posterior ocelli separated from eyes by 0.4–0.7× its diameter in dorsal view; 4) metasoma entirely orange or orange with tergite V blackish centrally, tergites VI+ black; 5) hind leg usually orange, with apex of femur and tibia and all tarsus blackish; 6) ovipositor robust, 1.4–1.7× as long as hind tibia.

Comments. Additional characters to the original description (♀) are as follows: body [?] 11.0–19.0 mm; mar- gin of gena behind eyes flat in dorsal view; margin of gena [?] 0.75–0.95× length of eye in dorsal view; tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe.

Male. (Figs 41–42). Similar to female in structure and coloration, except margin of gena 0.6–0.9× length of eye in dorsal view; posterior ocelli separated from eyes by 0.4–0.8× its diameter in dorsal view; sternite IX (Fig 44) longer than high, with lateral and anterior margins strongly sclerotised and slightly concave, with few bristles widely spaced posteriorly. Genital capsule (Figs 45–46): Paramere truncated apically, slightly narrower than the parameral lamina, with bristles except in posterior margin; volsellar lamina with bristles anteroapically spaced in anterior margin and with a set of three bristles in anterolateral region, just below the base of the digitus; cuspis robust with about five teeth aligned in the mid part until apex and with three few bristles spaced on apical region; digitus with teeth on apex, rounded distally and angular ventrally, with the margins of the apical region narrower than base; aedeagus with few teeth in apex and its apex slightly curved downward in lateral view.

Distribution. Argentina *, Brazil, Colombia **, Costa Rica, Panama, Paraguay ** and Trinidad and Tobago ** (Fig 47).

Biological notes. Parasitoid of the Argiope argentata (Fabricius, 1775) and Metazygia sp. [mentioned as Leucage mariana (Taczanowski, 1881) by Gauld (1991)] (Gonzaga & Sobczak, 2011).
