lachataoensis Garcia Aldrete & Casasola (2012), in that the distal processes of the male hypandrium
are much more slender posteriorly, each process bearing a sclerotized, small acuminate projection proximally on inner side, and in having a transverse, strongly sclerotized area at the bottom of the median concavity.
It belongs to the Siphonella genus group (Kanmiya 1983), with the following characters: head much wider than long; face concave, with a linear median carina; gena narrow; frons speckled, thickly clothed with short setulae, and sparsely microtomentose universally or in reticular-form; scutum as long as wide, convex, minutely or weakly shagreened, glossy or entirely microtomentose in both sexes; male surstylus highly specialized, incrassate and semi-globose, larger than epandrium in lateral view; gonites not well demarcated; hypandrium
closed (Sabrosky 1980; Kanmiya 1983; Merz 2008).
small, membranous, joined laterally to each clasper; phallosome apodeme long, slender, distally divided in two arms, each ending in an elliptic membranous area (Fig.
simple, of two parts, the posterior one generally with a median posterior concavity, and side fields of long setae on postero-lateral corners.
small, fused on the sides to claspers; proximal halves of these, robust, setose, distal halves slender, elongate, straight, preapically dilated, terminally acuminate (Fig.
Right lobe of hypandrium

First flagellomere shorter than scape 3 and pedicel combined; hypandrium
