( Figs 191–199View FIGURES 191–200)

Epimecis tibialis Cameron, 1886: 217  . Lectotype ♀, Mexico (BNHM), designated by Townes & Townes, 1966: 19 [exam- ined].

Acrotaphus tibialis (Cameron)  , Townes & Townes, 1960: 256

Diagnosis. This species can be distinguished from all other species of Acrotaphus  by the combination of the following characters: 1) margin of gena flat behind eyes in dorsal view; 2) posterior ocelli separated from eyes by 0.1× (0.1–0.3× in male) its diameter in dorsal view; 3) hind leg orange, with distal 0.3–0.4 of tibia and tarsus blackish; 4) ovipositor 1,5–1.7× as long as hind tibia.

Comments. Additional characters to the original description (♀) are as follows: body [22.0] 15.0–22.0 mm; lower face [0.9] 0.7–1.0× as broad as high (from supraclypeal suture to base of antenna); margin of gena behind eyes flat in dorsal view; margin of gena [0.4] 0.4–0.5× length of eye in dorsal view; posterior ocelli separated from eyes by [0.1]× its diameter in dorsal view; distance from tegula to head greater than [0.5] 0.5–0.6× distance from tegula to hind margin of propodeum; epicnemial carina present ventrally, extending until reaching the level of the lower corner of pronotum laterally; fore wing [17.0] 9.0–17.0 mm; cu-a opposite to the base of Rs&M; 2 rs-m [0.7] 0.7–0.9× as long as abscissa of M between 2 rs-m and 2 m-cu; hind wing with abscissa of Cu 1 between M and cu-a [1.15] 0.9–1.2× length of cu- a; tarsal claw with basal lobe quadrangular, with claw apex slightly overtaking the posterior margin of lobe; tergite I [1.8] 1.7–1.9× as long as posteriorly broad; tergite II [1.8] 1.5–1.8× as long as posteriorly broad; tergite III [1.3] 1.3–1.5× as long as posteriorly broad; tergites IV–V [1.3] 1.1–1.5× as long as pos- teriorly broad; ovipositor robust, [1.5] 1.5–1.7× as long as hind tibia; lower valve with swelling in the mid region.

Male. ( Figs 194–195View FIGURES 191–200). Similar to female in structure and coloration, except margin of gena 0.5× length of eye in dorsal view; posterior ocelli separated from eyes by 0.1–0.3× its diameter in dorsal view; sternite IX ( Fig 197View FIGURES 191–200) longer than high, with lateral and anterior margins strongly sclerotised, lateral margin flat and posterior margin slightly concave, with few bristles widely spaced posteriorly. Genital capsule ( Figs 198–199View FIGURES 191–200): 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 about three to six bristles in anterolateral region, just below the base of the digitus; cuspis robust with about four to six teeth aligned in the mid part until apex and with four to eight few bristles spaced on apical region; digitus with teeth in 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. Colombia **, Costa Rica, Guatemala, Mexico *, Panama, USA, Venezuela ** ( Fig 200View FIGURES 191–200).
