Lesteva haarlovi Shavrin , sp.n.

( Figs. 3-4 )

Type material. Holotype: male, Central Afghanistan, Koh-i-Baba mountains, Puistagoli, 02.08.1948, N. Haarlov / “3. Centralasiatiske Exp., Coleoptera , im.147. Puistagoli, from the very wet hillside, 2.8.48, N. Haarlov leg.” / Lesteva sp. det. Zanetti 2010 ( ZMUC). Additional label provided.

Description. Measurements: WH: 0.6; LH: 0.44; LA: 1.0; LE: 0.18; LT: 0.12; LP: 0.9; WPmax: 0.78; WPmin: 0.6; LES: 1.16; WE: 1.2; WA: 0.96 (VI tergite); LAE: 0.64. Body length: 3.0.

Body small, reddish yellow; apical margins of abdomen darker, brown; antennae, mouthparts,

ocelli yellow. Body covered by relatively long white setae, shorter on abdomen.

Head visible smaller than pronotum, 1.3 times wider than long; temples relatively long, weakly rounded to neck constriction. Eyes large, weakly convex, 1.5 times longer than temples.Anteocellar depressions weekly deep. Punctation irregular, dense and fine, interstices 1-2 times as broad as diameter of punctures, without microsculpture, glossy; surface between anteocellar depressions and ocelli without punctures. Ocelli relatively small, distance between ocelli 1.1 times the distance between ocellus and posterior margin of eye. Antennae relatively long, reaching anterior third of elytra, with small setae on all segments; antennomere I 2.5 times longer than wide, 1.6 times as long as II, antennomeres II-III, IV-V and VI-VIII with similar proportions. Length/ width of antennomeres are: I: 0.2 × 0.08; II–III: 0.12 × 0.06; IV–V: 0.1 × 0.06; VI–VIII: 0.12 × 0.06; IX: 0.12 × 0.08; X: 0.14 × 0.08; XI: 0.24 × 0.09.

Pronotum short, heart-shaped, weakly convex, 1.15 times longer than wide; sides of pronotum at minimal width parallel-sided; posterior angles weakly rounded. Pronotum midlined by impunctate stripe; punctation denser and coarser than that on head; interstices between punctures 1-2 times as broad as diameter of punctures, without microsculpture, glossy.

Scutellum small, triangular, without punctation and microsculpture.

Elytra flattened, wide, dilated posteriorly and obtusely rounded to apex, long, covered first five tergites, approximately as long as wide, 1.2 times longer than pronotum. Punctation regular, deeper and larger than those of pronotum; interstices between punctures 1–1.5 times as broad as diameter of a puncture, without microsculpture, glossy. Wings fully developed.

Abdomen convex, weakly tapering towards apex, 1.8 times narrower than width of elytra [elytraplural, elytron – singular], without punctation on all tergites, with distinct large isodiametric microsculpture, visible on low magnification.

Male. Aedeagus ( Fig. 6 ) oblong, narrow; median lobe strongly sclerotized, parallel sided in median half, strongly narrowed anteriorly, rounded apically; lateral parts of aedeagus tapering toward apex and not exceeding apex of median lobe. Paramerae very short. Apex of aedeagus laterally as in Fig. 7 . Sternite VIII with semicircular apical emargination.

Female unknown.

Comparative notes. Based on the type of aedeagus, the new species is closely related to L. barsevskisi Shavrin sp.n., from which it differs by smaller and less prominent body, coloration, by transverse pronotum, by larger puncturation, by the shape of aedeagus and endophallus.

Remarks. First record of the genus for the fauna of Afghanistan.

Etymology. The new species is named in honour of Mr. Niels Haarløv, Danish entomologist, who collect the type specimen in Afghanistan during 3 rd Danish Centralasiatic Expedition.
