A new genus of
Metopiinae is a moderately large subfamily with over 750 described extant species distributed in 25 genera (
Most
A list of Mexican
Wing venation and morphological terms predominantly follow
1 | Face with a large shield-shaped area bounded by a sharp carina. Tergites 1 and 2 fused (clearly visible in lateral view). Laterotergite 1 broad | |
– | Face more or less convex, without a concave shield-shaped area. Tergites 1 and 2 separated by a flexible membrane | 2 |
2 | Interantennal process of face produced dorsally into a high longitudinal lamella separating the antennal sockets; this lamella with a longitudinal groove in the dorsal surface, just below the median ocellus ( |
3 |
– | Interantennal process of face not produced dorsally as a longitudinal lamella, or if a weak, short lamella present, it does not have groove in the dorsal surface | Other genera of Metopiinae |
3 | Propleuron almost cubical in profile, resembling fore coxa in shape. Mesosternal region with a pair of flattened finger-like processes projecting backwards over bases of mid coxae. Upper half of mesopleuron strongly inflated | |
– | Propleuron not cubical in profile. Mesosternal region smooth or with a weak lamella before mid coxae, without finger-like processes. Mesopleuron laterally usually not strongly inflated | 4 |
4 | Face and clypeus not especially convex in lateral view, separated by weak and broad transverse impression. Mandible with lower tooth strongly reduced, represented as a small tubercle; upper tooth large, chisel-shaped ( |
|
– | Face and clypeus moderately to very strongly convex in lateral view; clypeus not separated from face. Mandible with lower tooth shorter, subequal to or longer than upper tooth, not especially reduced, and upper tooth more or less pointed, not chisel-shaped. Propodeum with carinae not as above. Flagellomeres of antenna more or less elongate | 5 |
5 | First metasomal segment weakly to quite strongly tapered anteriorly, but always evenly so, thus the anterior 0.4 is not parallel sided; its spiracle near its anterior 0.3. Sternite 1 short, at most reaching about 0.3 of length of tergite. Mandible with lower tooth much shorter than upper tooth | |
– | First metasomal segment petiolate anteriorly, the anterior 0.4 slender and parallel sided; its spiracle near, at or behind the centre. Sternite 1 long, reaching more than 0.5 of length of tergite. Mandible with teeth subequal or with lower tooth longer than upper tooth |
The new genus contains only the type species,
The new genus belongs to the group of three genera (
Fore wing length 9.5 mm, body length about 12.6 mm. Body and legs predominantly black, flagellum yellowish brown, wings yellow with distal margin broadly infuscate (
Named after the type locality, Ojuelos de Jalisco. Gender masculine.
Female.
Male unknown.
