Description. Body black, covered with fine and very dense silver-grey and yellowish pubescence. Length: 8.6-12.0 mm, maximal width: 2.5-3.2 mm.

Head flattened, transverse, with slightly convex eyes. Dorsal surface with very dense pubescence, irregular coarse punctation, middle portion between antennal bases with visible longitudinal and very thin impressed line. Antennal bases wide, extended, with visible forward-facing sharp tooth apically. Labrum pubescent, covered with numerous long setae. Clypeus dark-brown or black, transverse, covered with long yellowish setae of forehead. Head oriented ventrally, so that forehead and mandibles not visible from dorsal surface. Cheeks convex, with very dense yellowish pubescence. Antennae dark-brown, covered with sparse pubescence; basal antennomere short, with dense pubescence; antennomere 2 relatively short, wide, with rough surface, yellowish pubescence and sparse, coarse spots; antennomere 3 short, from basal portion narrowed apically, with yellowish pubescence; remaining antennomeres dark, paler on basal portions and with paler pubescence.

Pronotum black, subcylindrical, with very dense silver-grey and yellowish pubescence, and with very coarse and deep impressed punctation and wrinkles. Basal angles of pronotum indistinct. Apical margin of pronotum widely impressed; basal margin slightly concave behind basal angles, with very narrow transverse impression. Dorsal disc of pronotum with five massive longitudinal keels; basal sides of central keel white. Length of pronotum: 1.9-2.9 mm. Width of pronotum: 1.7-2.2 mm. Scutellum small, transverse, widely rounded or slightly concave apically, with dense pubescence.

Elytra parallel-sided, with uneven surface: impressed behind scutellum and before middle; black, slightly flattened dorsally, with visible humps behind shoulders, with keel-shaped, narrow, flattened apical elevation along suture, and with very coarse punctation and small, elongate, dark bumps. Elytra covered with very dense yellowish pubescence. Apical portions of each elytron with pale dorsolateral spot, behind them forming several light lines, some of which divided. Apex of elytra concave. Surface of elytra covered by irregular, short and white setae. Length of elytra: 6.1-8.2 mm, width of elytra: 2.5- 3.0 mm.

Ventral surface of body shiny, covered with dense, silver-grey and yellowish pubescence, except of dark-brown neck, smooth heart-shaped area in front of the hind legs and a round area in the anal portion of the abdomen; laterally on the sides with longer sets. Legs covered with dense yellowish pubescence.Tarsomeres black or dark-brown, covered with silver-grey pubescence.

Differential diagnosis. Regarding the shape of the habitus, the new species is somewhat similar to the Bornean Z. borneoticum (Breuning, 1969) , from which it differs by the paler coloration of the elytra, and larger, wider, less curved, sloping dorsolateral preapical spot. Dorsal disc of pronotum of a new species with five more developed massive longitudinal keels than that in Z. borneoticum . White portion of the central longitudinal keel of the pronotum is longer than that in Z. borneoticum The scutellum of a new species is covered with pubescence of the same coloration as the basal part of the elytra, but scutellum of Z. borneoticum is covered with more paler pubescence.

Etymology. This species is named after my colleague, well-known Russian entomologist Andrei A. Legalov (Novosibirsk) in appreciation of cooperation, and in gratitude for his great contributions to the knowledge of Curculionidae and Attelabidae of the world.
