Material examined

COSTA RICA • 1 ♀; Puntarenas, Osa Peninsula, 4 km NW of Rincon; 11 Aug. 2001; A. Borkent leg.; CNCI • 1 ♀; same collection data as for preceding; Rio Agujas; 10–20 Aug. 1996; A. Azofeifa leg.; Malaise trap; CNCI.

Description

Female

MEASUREMENTS (n = 2). Head width 256–306; flagellomeres 31–34, 21, 23–24, 23, 26, 24–26, 27–28, 29–31, 42–44, 46, 47–50, 43–51, 58–62; AR 1.14–1.21; FR 1.5–1.75; wing length 946–1016; wing width 371–397; costal ratio 0.63; spermathecal length 50–55; spermathecal width 46–56; spermathecal neck 8–11; spermatheca/neck ratio 0.16–0.2.

THORAX. Legs with femora and tibiae brown.

GENITALIA (Fig. 12f). 9 th sternite anterior branch apex broadly rounded, apices nearly touching medially; posterior branch acutely tapering at base, basal half directed posteriorly, apical half curving posteromedially, apex with small hook. 2 major spermathecae.

Distribution

Puntarenas (Costa Rica) (Fig. 13).

Remarks

Ceratoculicoides sp. F 3 can be distinguished from other Ceratoculicoides by the combination of major spermathecae being <70μm, concave posterior margin of the 9 th sternite with the posterior branch tapering in the basal half and ending in an acute point (Fig. 12f), and its flagellum ratio being>1.5. Ceratoculicoidesborkenti sp. nov. is very similar, but its flagellum ratio is <1.5.
