Key to Costa Rican species of Anicetus

(Females)

1. Pedicel (Fig. 1262) almost symmetrical in profile, subtriangular without a conspicuous, elongate ventral projection; hind tibia pale yellow with a pair of conspicuous dark brown rings ........................................................... annulatus Timberlake (p. 506)

- Pedicel (Figs 1268, 1274-1279, 1295, 1300) strongly asymmetric in profile with dorsal margin straight and ventral margin conspicuously elongate; hind tibia orange to dark brown, occasionally orange with a pair of broad dark brown rings ............ 2

2 (1) Frontovertex (Fig. 1269) throughout with distinct punctate-reticulate sculpture of cell size slightly smaller than diameter of eye facet; funicle (Fig. 1268) not longer than first segment of clava (measured dorsally) .......................................................... 3

- Frontovertex mostly smooth and shiny, with very shallow sculpture only in ocellar area; funicle (Figs 1274-1279, 1295, 1300) longer than first segment of clava ............4

3 (2) Ovipositor clearly exserted (Hab. 186), exserted part about 1.3X as long as mid tibial spur ..................................................................................... arche sp.nov. (p. 508)

- Ovipositor hardly exserted, the exserted part not more than half as long as mid tibial spur ..................................................................................... oroso sp.nov. (p. 510)

4 (2) Ovipositor not exserted or hardly so with exserted part not more than 0.7X as long as mid tibial spur (Hab. 187, 188) ............................................... lysithea sp.nov. (p. 511)

- Ovipositor strongly exserted (Hab. 189), the exserted part at least as long as mid tibial spur ....................................................................................................................... 5

5 (3) Scape (Fig. 1295) relatively broad, at most 1.4X as long as broad [length measured from base to distal margin of ventral lamina; width from dorsal margin in distal half of scape to ventral margin of lamina]; clava less than 2X as long as broad ............... .......................................................................................... cheras sp.nov. (p. 515)

- Scape narrow, at least about 1.6X as long as broad; clava more than 2X as long as broad ................................................................................. apatos sp.nov. (p. 517)
