Acrotaphus franklini Gauld, 1991

( Figs 82–90 )

Acrotaphus franklini Gauld, 1991: 329 . Holotype ♀, 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 0.6–0.7× length of eye in dorsal view; 3) posterior ocelli separated from eyes by 0.4–0.7× its diameter in dorsal view; 4) mesosoma black, except scutellum orange or mesosoma orange with propleuron, pronotum, mesoscutum and anterior and ventral region of mesopleuron black; 5) metasoma orange, with tergites V+ black; 6) ovipositor robust, 1.3–1.6× as long as hind tibia.

Comments. Additional characters to the original description (♀) are as follows: body [12.5] 12.0–17.0 mm; mar- gin of gena behind eyes flat in dorsal view; margin of gena [0.4] 0.6–1.0× length of eye in dorsal view; tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe. Male. ( Figs 85–86 ). Similar to female in structure and coloration, except margin of gena 0.6–0.7× length of eye in dorsal view; posterior ocelli separated from eyes by 0.6× its diameter in dorsal view; sternite IX ( Fig 88 ) longer than high, with lateral and anterior margins strongly sclerotised, lateral margin slightly concave and posterior margin concave, with few bristles widely spaced posteriorly. Genital capsule ( Figs 89–90 ): 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 four to five bristles in anterolateral region, just below the base of the digitus; cuspis robust with about four to five teeth aligned in the mid part until apex and with three to four few bristles spaced in 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 on apex and its apex slightly curved downward in lateral view.

Distribution. Brazil *, Colombia **, Costa Rica, Ecuador ** and Peru * ( Fig 91 ).

Biological notes. One male was collected from the nest of the Trypoxylon (Trypargilum) lactitarse Saussure, 1867 (Crabronidae) . This record is similar to the strange case documented by Palacio (1999), who found a species of the Acrotaphus from the nest of the Trigonopsis violascens (Dalla Torre, 1897) (Sphecidae) . Palacio (1991) suggested this was an accidental case, where the solitary wasp captures and imprisons an already parasitized spider (with egg/larva of the Acrotaphus ). This is the first record of the genus Acrotaphus in nest of Crabronidae .
