Diagnosis.

Morphologically, Corticarina oscargloriorum is very similar to other Corticarina in many external features, but can be distinguished by the configuration of the male genital apparatus and the features in the key below.

Description.

Length: 1.1 mm. Body oval, convex and little bright (Figure 1). Yellowish grey-brown; antennae (except for the two first articles) and tibiae dark grey-brown; two first articles of antennae and legs yellowish grey-brown. Metathoracic wings fully developed.

Head (Figure 1) slightly transverse (WL = 1.8-1.9). Labrum arcuate at anterior margin. Eyes large (L = 0.073 mm) and little protruding (E = 0.5-0.6); eye facets as large as head punctures. Puncturation very fine ( Ø = 0.006-0.007 mm) and sparse, barely distinct. Temples indistinct. Antennae (Figure 2) long (L = 0.398 mm). First antennomere spherical, almost as wide as long; second slightly shorter and half as thin as first; from fourth to seventh almost identical and half as short as second; eighth as wide as long; ninth sub-conical, longer than wide and 1.2 times as long as tenth; tenth 1.1 times longer than wide; eleventh twice as long.

Pronotum (Figure 1) moderately convex and little transverse (WL = 1.2-1.3); greatest width at anterior third. Lateral margins regularly rounded and denticulate. Postmedial circular depression present; lateral impressions somewhat distinct. Pubescence whitish, short (L = 0.019-0.020 mm) and recumbent. Punctation fine ( Ø = 0.011-0.012 mm) and sparse.

Elytra 1.5 times as long as wide. Callosity humeralwell-marked and posteriorly prolonged until becoming slightly carenated in the humeral region. Pubescence short (L = 0.016-0.018 mm) and recumbent. Punctation fine ( Ø = 0.014 mm) and sparse. Six abdominal sternites visible. Male pro-tibiae with a tooth on internal apical third.
