Trichomyia biloba Quate, 1999: 413 View in CoL , figs. 1A-D.
Material examined: 1 paratype ♂ ( BMNH) Panama, San Blas Nusagandi Reserve, 09°20′N, 79°00′W, 19-26.III.1994, J. Pickering leg.
Diagnosis: Palpus with four segments, first two partially fused. Male terminalia present hypandrium fused with gonocoxites, gonostylus little sclerotized, and aedeagus bifurcated with a membranous sheath. Cercus cuneiform and hypoproct with bilobed apex.
Supplementary description: Male: Head subcircular in frontal view, rounded eyes. Supraocular bristles in a single row. Antennal socket subtriangular, with a short distance between them,less than ⅓ the length of the antennal socket ( Fig. 1A View Figures 1 ). Occipital bristles present in almost the entire occipital plate. Palpus with four segments, the first two partially fused, first and second segments with sensilla grouped in a pit, on the basal portion in the first and on the apical portion in the second; palpus formula 1.0:1.0:1.5:1.3 ( Fig. 1B View Figures 1 ). Antenna incomplete in examined specimen, scape subcylindrical and subspherical pedicel, first flagellomere of the same length as the second flagellomere; first flagellomere subcylindrical, other flagellomeres piriform, asymmetrical; ascoids approximately twice the length of flagellomere, filiform, and sinuous ( Fig. 1C View Figures 1 ). Wing: Sc ending in C, sclerotized and without microtrichia;r-m present,radial fork and medial fork clos- er to the base of wing than the apex of the CuA₂; R₄ ₊ ₅ complete at base ( Fig. 1D View Figures 1 ). Male terminalia: hypandrium fused with gonocoxites forming a wide plate that covers the genitalia, with lateroposterior pilose arms directed to the external lateral and with three spinous setae. Gonostylus little sclerotized, with acuminated apex, basally fused and divergent apically. Aedeagus bifurcat- ed and convergent with a membranous sheath, ejaculatory apodeme short, 0.5 times the length of parameres ( Figs. 1E, 1F View Figures 1 ). Cercus cuneiform in ventral view with bristles randomly distributed throughout its length. Hypoproct with micropilosity and bilobed apex. Epandrium rectangular with apical micropilosity and without alveoli ( Fig. 1G View Figures 1 ).
