Trichomyia intricata Quate, 1996: 10-11 , fig. a.

Material examined: 1 paratype ♂ ( USNM) Costa Rica, Limon, Puerto Viejo de Talamanca, 20-23.VII.1993, sea level. L.W. Quate, leg.

Diagnosis: Palpus with three segments. Ascoids are digitiform and C-shaped. Male terminalia with gonocoxites, cylindrical arm of gonocoxite, strongly sclerotized gonostylus, and bifurcated aedeagus. Cercus cuneiform, epandrium trapezoidal and pilose with concentrated alveoli at the apex of the lateral regions.

Supplementary description: Male: Head oval, wider than long in frontal view,rounded eyes.Supraocular bristles in a single row. Antennal socket subtriangular, with a short distance between them, almost together ( Fig. 3A ). Occipital bristles in a row restricted to the posterior margin of the eye. Palpus with three segments, first segment with sensilla grouped in a pit, palpus formula 1.0:1.0:0.6 ( Fig. 3C ). Antenna incomplete, scape subcylindrical and subspherical pedicel, flagellomeres piriform and asymmetrical, first flagellomere of the same length as the second flagellomere. Ascoids digitiform and almost C-shaped, with 1.4 times the length of the flagellomere ( Fig. 3B ). Male terminalia: hypandrium fused with gonocoxites. Arm of gonocoxite cylindrical, projected diagonally, at an angle of 45°, pilose, with a row of setae on the inner margin. Gonostylus strongly sclerotized and digitiform, with a short subapical identation at the apex, articulated with the ventral region of gonocoxite. Aedeagus bifurcated, one pair of subtriangular parameres with slightly curved apices, ejaculatory apodeme short, 0.6 times the length of parameres ( Figs. 3D, 3E ). Cercus cuneiform in ventral view with bristles randomly distribut- ed throughout its length. Hypoproct with micropilosity and rounded apex. Epandrium pilose and with a concave posterior margin, with alveoli distributed and concentrated at the apex of the two lateral ( Fig. 3F ).
