Redescription.

Length: 1.8-2.0 mm. Body oval, elongated and convex. Either yellowish or reddish grey-brown in its entirety; some specimens have only their head and pronotum reddish grey-brown. Pubescence simple, slightly thick and short (L = 0.019-0.022 mm). Metathoracic wings fully developed.

Head transverse (WL = 1.8-1.9). Punctation well-marked, however not dense; distance between punctures greater than puncture diameter ( Ø = 0.010-0.012 mm). Eyes normal, sub-hemispherical, moderately protruding (E = 0.9) with facets ( Ø = 0.011-0.012 mm) as large as head punctures. Long antennae (Fig. 10) (L = 0.594 mm) reaching the base of the pronotum. 1st segment thick; 2nd ovoid, almost identical to 1st and 0.9 times larger than 3rd; 4th, 6th and 7th identical and 0.6 times shorter than 3rd; 9th and 10th transverse.

Pronotum (Figs 9, 11) convex and moderately transverse (WL = 1.8). Anterior margin curved. Lateral margins, from callosity to last third, more or less parallel and converging from here to the base. Large callosity (1/3 of side length) not surpassing the lateral margin of the pronotum. Callosity face visible from above. Gland pore visible, forming an obtuse angle rearwards and a 30°-31°angle with the body axis. Posterior angles obtuse. Basal groove visible. Basal foveae hardly visible. Punctation well-marked and dense; distance between punctures less than puncture diameter ( Ø = 0.011-0.012 mm).

Elytra three times as long as pronotum. Elytra with finer and more scattered punctation than that of the pronotum. Distance between punctures greater than puncture diameter ( Ø = 0.011-0.012 mm).

Aedeagus (Fig. 13) (L = 0.138 mm) apically extended. Lateral margin with a small protuberance on the basal third. Endophallic orifice not visible. Parameres very elongated, triangular (Fig. 12) (L = 0.080-0.090 mm). One or two apical setae (L = 39.28 µm). Scarce pores either with or without setae.

Biology.
