Recognition
Vizcayinae’s phylogenetic position is intermediate between the basal Asiracinae and the derived subfamilies (Eudelphacinae).
Description of the genus from Muir, 1917: 351:
Head narrower than thorax; vertex longer than broad (1.70 to 1), base slightly wider than apex, mediolateral carinae meeting well before the apex, Y-shaped carina obsolete, length of face nearly two and one-half times the width at apex (1 to 2.4), apex wider than base, sides nearly straight, lateral carinae distinct, a single median carina faint on apical half and obsolete on basal half, a distinct carina across gena from base of antenna to the lateral corner of base of clypeus; clypeus shorter than face, tricarinate; head in profile rounded at junction of vertex and face. Antennae nearly twice the length of head and pro- and mesothorax together, second joint more than one half longer than first (1.6 to 1), first joint flattened, wide, thin, second joint terete, evenly covered with raised sense organs and short spines. Hind margin of pronotum slightly and evenly emarginate, carinae obsolete; mesonotum with three very fine carinae. Legs long and slender, hind tibiae with one basal, one medioapical, and five apical spines; hind tarsi not quite half the length of tibia, basal joint longer than the other two together (1 to 0.70), spur not as long as the basal joint, cultrate, convex on both sides, seven teeth on hind margin and one at the apex.
Tegmen long, narrow, median vein not touching the radius.
This is a very distinct genus belonging to the Alohini and coming nearest to Proterosydne. It has some affinity, at least superficially, to Lanaphora of the Tropidocephalini.

At this time, Genbank has sepence data for Vizcaya piccola (18S, 28S from Urban et al. (2010). Bold does not have any molecular resources for this subfamily.
