clypeus

For example, the male has a yellow clypeus and the first antennal flagellomere is longer than the second, as in the bachue species group.

Female clypeus mostly orangish brown, apex forming an angle of about 120[degrees].

Anterior angles of clypeus not visible in dorsal view.

- Paraclypei distinctly shorter than clypeus; 2nd antennal segment equal or subequal to 3rd; paramere sinuated at apex, forming concave margin, with apices acutely produced, inner spine of blade very prominent a little bent, beak-like, with distinct ridge .............................................serigera (Westwood, 1837)

Metope width (L:W at widest point 1.23 [+ or -] 0.05, n = 10), sharply enlarged above clypeus (near level of antennae in frontal view), with distinct median carina running from fastigium to level of antennae, but obsolete ventrad of antennae.

--Scutellum with disperse setae; forewing with 3RSb vein 3.14 to 3.47 times longer than 3RSa vein; face 1.38 to 1.47 wider than longer; clypeus dark yellow (female) or yellow (male) T.

A recently described species of Disceratus was first placed into the new subgenus Tettohenicus Gorochov 2012 within the genus Gnathoclita Haan 1843, the latter being distinguished by strongly elongated mandibles and clypeus in males, and belonging to the tribe Eucocconotini (Beier 1960).

Eye interdistances: AME-AME 0.20, AME-ALE 0.21, PME-PME 0.40, PME-PLE 0.53, AME-PME 0.23, ALE-PLE 0.30, clypeus height at AME 0.11, clypeus height at ALE 0.10.

Clypeus yellow; developed and protruded, in lateral view, exceeding the face level (Fig.

Eye much more strongly swollen laterally than in female; inner eye margins about 1.5 X [about 1.4 X] further apart from each other at vertex than at clypeus. Gena narrow [more or less wide], in lateral view about 0.3 X [slightly less than 0.5 X] as wide as eye.

The genus is characterized by the narrowed, convex, and medially raised clypeus. The mandibles are triangular or narrowed with 6-9 teeth.

corythus because its cephalic carina is positioned near middle distance of the head; thus the frontal region of head (frons) is longer than the clypeus (Figure 2a); in C.

Clypeus short and steeply inclined with few stout erect bristes.
