Neosilba bella
Description of holotype:
Male body size: 6.7 mm
Head: Frons: narrowed toward lunule, 1.8 mm long and 1.4 mm wide; length/width ratio:1.28. Lunule with 8-9 setulae. Ocellar plate with 8 strong bristles, 2 inter ocellar bristles under ocellar plate and 2 others above ocellar plate. Antenna, 1.8 mm long, with one prominent bristle on the pedicel. First flagellomere 0.846 mm long and 0.34 mm wide; length/width ratio: 2.48. Arista 0.9 mm long and plumose. Palpus large and broad.
Thorax: thorax 2.0 mm in long dorsal view and setulose. Scutellum bare, with 2 strong marginal basal bristles with 3 setae between it and 2 strong marginal apical bristles, and 3 setae between marginal
apical bristle and marginal basal bristle at each side of scutellum. Anepisternum with a cluster of 5 strong posterior bristles, with one setae below, and a cluster of 4 strong anterior bristles, weaker than posterior bristles. Wings: hyaline, 5.2 mm long and 2.3 mm wide; length/width ratio: 2.26; hyaline with brownish veins and microtrichia, calypteres white with white fringes and with about 12 long blackish setae at fold.
Male terminalia: Total length: 0.93 mm; epandrium short, 0.46 mm long, but longer than wide; 0.38 mm wide, length/width ratio: 1.21 and with long hairs, longer at end of epandrium (figs. 1 and 2). Aedeagus with filament fine and slender after “C” shaped base until apex, ending slightly beyond prensisetae. Surstylus with 10 strong prensisetae distally. Cerci with scarce but long setae; easily seen in ventral and lateral views. Paramere with a conspicuous shape, more or less triangular
