MEXICO • ♂; Veracruz, Puente Nacional, 15. vi. 1964, F. S. Blanton leg., USNM .

Diagnosis.

Xiphocentron julus is particularly similar to X. tampati sp. nov. by the posterior margin of sternum IX mostly straight with very small mesal lobes; and can be differentiated from this and other species mainly by the uniform width of the preanal appendage, the posterior margin of sternum IX mostly straight with very small mesal lobes, and the paraproct apex oblique.

Synopsis.

Male. Forewing length 4.0 mm. Color overall brown, forewing uniformly dark brown. Genitalia (Fig. 10 A – C). Tergum IX in lateral view, wide basally, narrower apically (Fig. 10 A); in dorsal view, posterior margin with two ogival shaped lobes and small lateral flanges (Fig. 10 B). Sternum IX, in ventral view, posterior margin abruptly truncated, straight at its ventro-apical margin, forming two low lobes, barely produced (Fig. 10 C). Paraproct, in lateral view, slender tapering to a pointed apex (Fig. 10 A); in dorsal view, apex round and forming two apical lobes (Fig. 10 B). Preanal appendage in lateral view, regularly narrow and pointed at apex (Fig. 10 A). Inferior appendage, in lateral view, about 2.5 × as long as tergum IX, coxopodite and harpago completely fused to each article, inner face with longitudinal area of dense, long spine-like setae, and row of regular setae from midlenght to apex (Fig. 10 A); basal region (coxopodite) wide, mesal sclerite region indistinct; apical region (harpago) narrow, digitate 2 × as long as basal region, curved dorsad (Fig. 10 A); in dorsal view, strongly curved mesad, apex twisted posterad (Fig. 10 B). Phallus tubular, very long and narrow, reaching segment V, basally conical, subapically annulate, weakly sclerotized, apex enlarged.

Distribution.

Mexico, Panama.
