Diagnosis. Labrum entire. All black. Elytron with regular interneurs, 2, 4, and 6 with series of moderately impressed setigerous punctures, adjacent intervals catenate; interneurs with regularly spaced and moderately cribriform punctulae; apex with more or less similar­sized lateral and sutural acute dentiform projections.

Description. Color and luster: Black. Tips of mandibles, sides of antennomeres 4­11, and in some specimens, sides of abdominal sterna rufopiceous. Surface very shiny. Form: Labrum entire. Head ( Fig. 14a ) behind eye elongate, taper­rounded in both sexes. Prothorax subtubular, short, robust, sutures effaced, dorsal surface convex and densely punctate and transversely rugose, punctures very small. Elytron with apex ( Fig. 14 b) moderately oblique, with more or less similar lateral and sutural acute dentiform projections, margin between dentiform projections moderately lobed; interneurs with regularly spaced and moderately cribriform punctulae and 2, 4, and 6 with series of moderately impressed setigerous punctures. Metasternum with scattered setae; abdominal sterna III­VI of male with patches of discal setae. Sternum VI ( Fig. 14 c) moderately v­notched in both sexes. Aedeagus ( Fig. 14 d) with ostium elongate, apex a double scimitar, the distal with rounded sides, parameres glabrous. Size: medium, 14.5 to 18.0mm in length, 4.28 to 4.70mm in width.

Specific epithet. The specific epithet, dable , is part of the Spanish word, agradable, meaning “pleasing.”

Notes. Adults of this species are remarkably similar to those of Agra solisi (below) except for leg color and obliqueness of the elytral apex. An illustration of famula­group stylomere 2 is on the Agra fortuna web page.
