Neosilba orbata View in CoL sp. nov.
( Figs. 6 View FIGURE 6 A-D)
Type data: Holotype ♂. COLOMBIA, Tolima, Ibagué. 04°27’215”N, 75°13’271”O, 1259 m, 18.I.2006, R.
Castañeda & A. Osorio. In Passiflora vitifolia Kunth ( MEN-UT).
Etymology: The name of the species is an adjective that means circular (from Latin orbis = circle and suffix -aceus = similar) in reference to the circular shape of the base of the aedeagus.
Diagnosis: Neosilba orbata could be recognized by the epandrium as long as wide in lateral view ( Fig. 6B View FIGURE 6 ) and very thin in ventral view ( Fig. 6A View FIGURE 6 ); the special character in the new species is the basal part of the aedeagus, which is circle-like shaped ( Fig. 6B View FIGURE 6 ), more than the common C-like shape in the other species; the tip of the filament slightly S-like and apex is slightly wider, surstylus with 10 prensisetae at each side ( Figs. 6B, C View FIGURE 6 ). The other two described species with those similar characters is N. zadolicha ( Figs. 6 View FIGURE 6 E-H) and N. pseudozadolicha . N. zadolicha has the epandrium 5 times longer than wide ( Fig. 6E View FIGURE 6 ). N. pseudozadolicha differs by the number of prensisetae of the surstylus, 5 at each side.
Description: Body length 4.48 mm long, 1.85 mm wide in dorsal view at pteropleuras. Head: 1.77 mm wide, 1.51 mm high, 0.81 mm long; front 0.384 mm wide at the lunule, 0.512 mm wide lower ocelar triangle; frontal lunule with 8 setulae; postpedicel 0.96 mm long, 0.32 mm wide in lateral view; arista 1.00 mm long, middle setulae longest, 0.011 mm long; subvibrissal area with 5 setulae. Thorax: 1.44 mm wide at pteropleura, 1.66 mm long; anaepisternum with 4 anterodorsal and 6 posterior bristles; scutellum with 6 setae between lateral bristles; fringes of calypteres with 6 brown setae; wing 5.62 mm long, 2.03 mm wide, hyaline. Abdomen: 2.00 mm long. Male terminalia: 0.88 mm long, 0.66 mm wide (1.16 times as long as wide); epandrium 1.15 mm long, 0.98 mm wide; medium surstylus covered by epandrium in ventral view, but 0.089 mm long distally finger-like exposed; surstylus with 10 prensisetae at each side; paramere triangle-like shape in ventral view and finger-like in lateral view; aedeagus smooth; the basal section and the filament is the same thickness, the basal section (commonly C-shaped), circular-shaped; filament 1.413 mm long, 0.089 mm the wider part, apex S-like in lateral view, tip slightly widened; cerci 0.120 mm long, 0.105 mm wide.
Host: N. orbata was collected from fruits of Passiflora vitifolia Kunth.
