Description.

Length: 1.6-2.1 mm. Body oval, elongated and little convex. Either yellowish grey-brown or dark grey-brown; head and pronotum reddish grey-brown; appendages yellowish grey-brown. Pubescence simple, flattened and short (L = 0.040-0.060 mm). Metathoracic wings fully developed.

Transverse head (WL = 1.9-2.0). Punctation well-marked and dense; distance between punctures less than puncture diameter ( Ø = 0.012-0.016 mm). Normal eyes (L = 0.115 mm), sub-hemispherical and protruding (E = 0.95-1.0). Eye facets ( Ø = 0.008-0.010 mm) smaller than head punctures. Long antennae (Fig. 15) (L = 0.690 mm) reaching the posterior margin of the pronotum. 1st antennomere spherical and wide; 3rd as long as 2nd however narrower; 4th and 8th identical and 1.8 times shorter than 3rd; 5th, 7th and 9th almost identical and 1.4 times shorter than 3rd.

Pronotum (Figs 14, 16) slightly transverse (WL = 1.7). Anterior margin curved. Large callosity (1/3 of side length), barely protruding from the lateral margin of the pronotum. Callosity face “flattened” on the pronotum and clearly visible dorsally. Gland pore visible; forming an obtuse angle rearwards and a 27°-28°angle with the body axis. Lateral margins parallel until middle area and from there, converging to the base. Posterior angles obtuse. Basal foveae present. Punctation pronounced, dense but less apparent than on the head; distance between punctures less than puncture diameter ( Ø = 0.014-0.018 mm).

Elytra 3.5 times as long as pronotum. Punctation finer and more scattered than that on the pronotum; distance between punctures greater than puncture diameter ( Ø = 0.016-0.018 mm).

Aedeagus (Fig. 18) (L = 0.155 mm and A = 86.29 µm) apically extended. Preputial sac with a thin membrane. Basal third of lateral margins with a small protuberance. Endophallic orifice visible, located on the base of the aedeagus and apically truncated. Endophallic armour made up of small spines. Parameres (Fig. 17) (L = 64.67 µm and A = 23.27 µm). Numerous pores either with or without setae. Two long apical setae (L = 54.44-85.18 µm).
