Cryptoserphus hamiferus Brues, 1940: 261 (female).

Description. Head weakly convex. Genae 0.23 times as high as eye width, with deep vertical groove. Clypeus 0.7 time as wide as face, with depressed border along anterior margin. Labrum triangular, 2.4 times as long as wide. Malar sulcus present. Mandibles with blunt point. Face, clypeus and labrum with noticeable rough punctures. Antennae 1.6 times as long as head height, 13-segmented. Antennomeres almost quadrate; ratio of antennomere lengths as following: 2.4:1.1:2.8:1.5:1.5:1.6:1.6:1.8:1.7:1.8:2.0:2.0:3.7. Epomia uninterrupted. Depression below humeral tubercles with vertical wrinkles, which run over centre of pronotum as a strip of weak reticulation. Notauli as long as tegulae. Mesopleural perforated suture complete. Horizontal mesopleural groove complete. Metapleuron with large smooth area, being slightly rough in its lower half. Upper 1/5 of this area shiny and separated by shallow groove. Propodeum short, with smooth reticulation. Radial vein joining costa at 38°. Radial cell 0.8 times as long as depth of pterostigma. Costa not developed beyond radial cell. Ovipositor sheath 4.6 times as long as wide, 0.6 times as long as hind tibia, curved apically, with few small setae.

Holotype. Female, MCZC no. 8267. The metasoma is split laterally, with heavily swollen base.
