ID info:
Keying to Genus in Subtribe Gastrosericina:
1. - The large and light-green colored eyes, small eye-gap and short antennae length, fails for the genus Larropsis.
2. - The short, blunt abdominal apex with a wide pygidium, very small eye-gap and thick legs, are features that fail for the genus Tachysphex. Also, the two ocellar scars are club-shaped with long tails, but they are very hard to see.
3. - The overall body shapes, proportions, and the wing vein patterns suggest the genus Tachytes. (incorrect, see comments below)

Moved
Moved from Tachytes. The long rake setae of the female fore tarsus and the shape of the anterior ocelli clearly rule out Tachytes (despite all that is said above).
