Neosilba cornuphallus
N cornaphallus n sp. belongs to the complex of N longicerata (Hennig) and can be easily separated from other species
examining the portion of aedeagus after the "C" shaped base and the concavity of epandrium.
Description: Holotype: Male reared from Mafarandubinha \Mamlkara salzmanmi, . Head Round in front view, frons broad with parallel sides, not narrowing toward lunule, with a
cluster of 4 inter-frontal setae slightly prominent at each side, right above lunule, other inter-frontal setae small and sparse; 2 prominent supra-orbital bristles, 2 ocellar bristles. Inner orbital bristles slightly larger than external orbitals. Lunule with a cluster of 5 setulae at each side. Antenna: scape and pedicel usual to genus; first flagellomere long, reaching palpus Palpus large and broad with one more piominent apical sub-marginal seta Thorax: Anepisternum with 5 prominent, evenly spaced posterior bristles aligned dorso-ventrally and 3 smaller anterior bristles aligned dorsoventrally Katepisternum with 2 prominent bristles and 3 setae; epimeron and episternum with 1 bristle each. Scutellum with a pair of prominent apical marginal bristles and 2 anterior submarginal bristles, with a cluster of 3 setae at each side between anterior submarginal bristles and apical bristles; and 2 setae between apical marginal bristles. Presternum bare. Abdomen with a tuft of very prominent bristles at each side of last abdominal segment, it resembles the situation found in N galbernma, although more stout in N cornuphallus n. sp.
Male terminalia: Paramere ligulate, pilose in inner margin (Fig. 6), aedeagus vvith variable diameter along its extension, apex of aedeagus large and ending in a smooth "S" shaped (Fig. 7, 8 and 9), ending close to cerci, base of aedeagus slender, right after the "C" shaped base the aedeagus is very slender and becomes large abruptly giving the impression, in lateral view, to enter a sclerotic structure (Fig. 8), this is the most remarkable autapomorphic character of this species Cerci small, lamellate, having the shape of a folded membrane (Fig. 9) with long setae in lateral view. Surstylus with long ventral posterior marginal setae (Fig. 7), the fiist 3 anterior marginal setae more spaced than others; posterior lobe of surstylus with 2 prensisetae perpendicular to aedeagus; and 14 prensisetae aligned parallel to aedeagus; of these the 3 anterior more spaced andthe 2 following setae grouped. Epandrium with long setae covering surstylus in lateral view The anterior doisal portion of epandrium concave, very curved (Fig. 9).
Adults reared from Inga spp., Inga edulis mart., Citharexylum myrianthum, Eriobotyra japonoca , Citrus sinensis, Guateria discolor, Ampelocera edentula,, Coffea arabica, Anacardium occidentale and Manilkara salzmannii.
