General diagnosis. length: 2.3–2.5 mm, width: 1.5–1.6 mm, dorsal surface dark bronze, shiny. Body egg-shaped, eyes flat. Females with dentate anal ventrite.
Description of Holotype. Measurements: total length: 2.40 mm; width: 1.52 mm.
Head bronze; eyes flat, nearly concave; inner margins of eyes parallel; widely spaced punctation on very fine, shiny microsculptured frons; glabrous.
Antennae 11-jointed; antennomeres 1, 2 enlarged; broadened from the antennomere 7. Pronotum bronze; base three times broader than length, in body axis; lateral margins regularly arcuate, converging anteriorly; anterior margin simply rounded; very fine, shiny microsculptured; without punctation, only some irregularly arranged smooth spots; glabrous.
Scutellum like head and pronotum, very fine, shiny, but regularly microsculptured; triangular; two times as broad as long; glabrous.
Elytra bronze-coloured; surface smooth, without any microsculpture; broadest in anterior third, longitudinal puncture rows clearly visible; hardly noticeable single setae arise from these pores; between puncture-rows slightly wrinkled; apicolateral half more rugose; humeral bulb and posthumeral depression distinct; lateral margin feebly serrate in apical third.
Ventral side blackish; very fine microsculptured, like pronotum; anal ventrite simple, only with transverse apical furrow.
Legs with typical strongly flattened tibiae, same colour as ventral surface. Male genitalia claviform (Fig 4).
Etymology: The species is named in reference to its bronze, shiny colouring.
Distribution: Venezuela (Anzoátegui, Guarico).
Differential diagnosis
Hylaeogena aeneonitens in general shape, and especially the flattened eyes, is closely related to H. lecerfi Obenberger, 1932 from Panama and H. nana (Kirsch, 1866) from Peru. However, the scutellum of H. nana is nearly equilateral and the general surface more shiny, with a slight greenish tinge on the pronotum, while H. aeneonitens is unicoloured. H. aeneonitens can be distinguished from the blackish H. lecerfi by the colour, the elytral pilosity and the distinct pronounced posthumeral depression.
The holotype and paratypes will be deposited in the ZMHB. Paratypes will be deposited in the MIZA, NMPC, BMNH, SGCB and MHCB.
