Type species
Rhytidaphora thailandica Reshchikov & Quicke gen. et sp. nov. by present designation.
Diagnosis
Rhytidaphora gen. nov. can be distinguished from other genera of Euryproctini by the following combination of character states: lower mandibular tooth much longer than upper (Fig. 1B); occipital carina broadly incomplete dorsally, joining hypostomal carina shortly before base of mandible; occiput with distinct concavity; fore wing without areolet (Fig. 2A); tarsal claws distinctly pectinate (Fig. 2B); T1 dorsal carinae well-developed, continuing as dorsal carinae of T2 (Fig. 2F); S1 very short (0.3 times as long as T1); T2 and T3 immovably fused (Fig. 2D); T1‒5 with deep basal and subapical transverse striate impressions (Fig. 2D, F); ovipositor rather short, straight, with subapical, dorsal notch (Fig. 2D).
Etymology
The generic name Rhytidaphora derives from Greek “ρυτίδα” – “wrinkle” and “φέρω” – “bear”, referring to the sculpture of the metasoma. The gender is feminine.
Description
MEASUREMENTS. Fore wing length 6.0 mm.
HEAD. Clypeus flat in lateral view (Fig. 2E), its lower margin blunt in its middle and slightly sharp laterally, bulging apically (Fig. 1B). Face rather sparsely setose (Figs 1B, 2E). Anterior tentorial pit rather large (Fig. 1B). Eyes bare (Fig. 2C). Lower mandibular tooth much longer than upper (Fig. 1B). Occipital carina broadly incomplete dorsally, joining hypostomal carina shortly before base of mandible. Occiput with distinct concavity.
MESOSOMA. Epomia absent. Notauli shallow and indistinct (Fig. 2C). Mesopleuron sparsely setose, not punctate (Fig. 2C). Epicnemial carina joining anterior margin of mesopleuron (Fig. 2C). Propodeum in lateral profile convexly rounded (Fig. 2E), with carinae complete except for area apicalis, which is absent (fused with area superomedia) (Fig. 1C). Fore wing without areolet (Fig. 2A). Pterostigma receiving vein Rs+2r at its basal 0.35. Vein 2m-cu with a single bulla (Fig. 2A). Hind wing with cu-a receiving Cu1 well below middle. Tarsal claws distinctly pectinate (Fig. 2A). Fore tibia with apical tooth (Fig. 2G–H).
METASOMA. Without obvious punctures but densely finely setose (Fig. 2D, F). T1 as long as broad with strong dorsal longitudinal carina continuing in dorsal carinae of T2 (Fig. 2F). Glymma absent (Fig. 2D). S1 rather short, 0.3 times as long as T1. T2 and T3 immovably fused (Fig. 2D). T1‒5 with distinct basal and subapical transverse impressions distinctly striate. Ovipositor very short, straight, with a long, shallow, subapical dorsal notch (Fig. 2D).
Species included
The genus is described as monotypic.
