Description. Body shiny, yellowish-brown, maxillary palpi, antennae and legs slightly lighter, length 1.20 mm, maximal body width 0.47 mm, maximal width of elytra as wide as maximal width of abdomen, whole body with ¿ne, short, decently dense pubescence.

Head about 1.47 times as wide as long, surface smooth, rostrum prominent, triangular, frons with ¿ne frontal depression, frontal fovea absent, vertexal foveae well-de¿ned situated at the level of anterior part of eyes, antennal tubercles weakly de¿ned, eyes large, slightly prominent laterally, about as long as strongly posteriorly convergent temples. Ventral anterior side of head with few long setae.

Antennae short, about 0.40 mm long, scape cylindrical, about 1.50 times as long as wide, pedicel about twice as long as wide, expanded apically, antennomere III elongate, antennomeres IV–IX about same length, IV–VII about as long as wide, VIII slightly wider than long, IX 1.5 times as wide as long, antennomere X twice as wide as long, terminal antennomere 1.70 times as long as wide, roundly pointed, antennal club from 2–3 antennomeres, not clearly separated from funicule. Relative length of antennomeres: 2.00 / 2.50 / 1.25 / 1.00 / 1.00 / 1.00 / 1.00 / 1.00 / 1.00 / 1.50 / 6.00.

Pronotum about 1.2 times as long as wide and twice as long as head, with V-shaped transverse sulcus located in basal third of pronotum length, foveae absent.

Venter smooth, with sparse pubescence, metaventrite about twice as long as mesoventrite in middle, mesocoxae not separated, metaventrite convex, metacoxae almost contiguous, apical metaventral process slightly de¿ned, roundly pointed, metaventrite in front of metaventral process with depression.

Elytra about 1.25 times as wide as long, smooth, with two minuscule but well-de¿ned antebasal foveae, sutural stria almost reaching apex of elytra, discal stria shorter, reaching basal two thirds of elytral length.

Abdomen large, surface of all tergites smooth, about as long as elytra and of same maximal width, ¿rst (IV) visible tergite longest, longer than second and third (V–VI) visible tergites combined, lacking foveae, depressions or carinae, paratergites IV–VI well-developed.

Legs simple, without any modi¿cation.

Aedeagus ( Figs 1–2 ) with basal bulb rounded, lacking dorsal diaphragm, left paramere well-developed, with three setae, right paramere short, large at apex, not visible dorsally, endophalus with one long internal apophysis.

Sexual dimorphism. Female unknown.

Differential diagnosis. Three species of the genus Aphiliops have been described so far, A. aubei (Reitter, 1881) , A. annae Poggi, 1992 and A. baccettii Poggi, 1992 . All are known only from Corsica or Sardinia (POGGI 1992, LÖBL & BESUCHET 2004). The new species differs from all of them by larger body (1.20 mm versus 0.94–1.16 mm), by elongate pronotum twice as long as wide, by absence of carinae on ¿rst visible tergite (IV), and by different shape of the aedeagus.

Etymology. The speci¿c name refers to the Asian continent; adjective.

Biology. Both specimens were collected by sifting of leaf litter in well-preserved mature poplar alley.

Distribution. So far known only from the type locality in Kazakhstan.
