sp. nov.

Dyschiriodes (Dyschiriodes) jelineki   sp. nov.

( Figs. 6 View Figs , 12 View Figs )

Type locality. Southern Iran, 15 km NE of Bandar Lengeh.  

Type material. HOLOTYPE: ♁, ‘S. IRAN, 15 km NE / Bandar Lengeh   / 25.–26.iv.1977 // Loc. No. 313 / Exped. Nat. Mus. / Praha // Dyschiriodes   / sp. n. / det. D Fedorenko 2006’ ( NMPC). PARATYPE: IRAN: 1 spec. with the same locality data as HT ( PBPC).

Description. Habitus as in Fig. 6 View Figs ; both HT and PT 3.70 mm long; HT moderately immature, fuliginous, anterior part of head, elytral base and apex lighter; surface of head and pronotum with distinct bronze lustre, surface of elytra with slight bronze lustre; legs rusty red, antennae and mouth-parts slightly lighter; PT very immature, rusty brown, head and pronotum with indistinct bronze lustre.

Head. Anterior margin of clypeus with sharp, moderately protruded lateral lobes, between them straight, clypeofrontal area with 4–6 dense and irregular transverse furrows; facial furrows deep, long, parallel in anterior half, moderately divergent posteriorly; distance between them shorter than eye length. Surface vaulted, smooth, with fine and sparse micropunctures. Eyes large and moderately convex. Antennae submoniliform.

Pronotum. Moderately convex; outline moderately and evenly rounded in posterior half, slightly rounded in anterior half; attenuated anteriorly; in HT 1.03 times and in PT 1.04 times as wide as long, in HT 1.44 times and in PT 1.41 times as wide as head; widest in posterior fourth.Anterior angles blunt, not rounded, posterior ones broadly rounded.Anterior transverse impression deep, without punctures and cross striae; median line deep, narrow; lateral channel distinct, reflexed lateral margin extended slightly below posterior setiferous puncture. Surface mirror-like, shiny, with very fine micropunctures.

Elytra. Laterally slightly flattened, ovate; HT 1.64 (HT) to 1.65 (PT) times as long as wide, 1.24 times as wide as pronotum; humeri strongly protruded, each elytron with blunt humeral tooth; base slightly sloping; outline slightly and regularly broadened on sides, broadest just before midlength; suture slightly depressed at base. Base without basal border and tubercles; BSP small, deeply connected with stria 1. Striae 1–7 very deep in basal three fourth (inner ones) or basal two thirds (outer ones), slightly weakened apically; striae densely and moderately roughly punctate anteriorly; punctures gradually disappearing apically, striae in latero-apical area impunctate; stria 7 deeper before apex; stria 8 very fine, consisting of a row of minute punctures in second third of length, just recognisable in posterior third before apical stria; intervals strongly vaulted in basal two thirds, slightly flattened latero-apically. Three PHSP, three DSP (anterior one in interval 3, middle and posterior ones near stria 3) and two ASP (in deep apical stria).

Protibia.Apical spine thin, moderately curved downwards and slightly inwards, as long as apical spur; the latter slightly curved; distal marginal tooth large, sharp, proximal one much smaller, blunt.

Aedeagus. Crumpled due to immaturity, ca. 0.58 mm long in HT. Apical lamella narrowed apically in lateral view ( Fig. 12 View Figs ). Paramere asetose.

Differential diagnosis. Dyschiriodes jelineki   sp. nov. belongs to the D. chalybeus   group sensu FEDORENKO (2000) (= D. bengalensis   group sensu FEDORENKO (1994, 1996)). It can be distinguished from the most similar D. (D.) mortchaensis ( Bruneau de Miré, 1952)   , known from Tchad and Arabian Peninsula, by several transverse, more or less parallel furrows on the head (indistinct oblique furrow and irregular rugosity below it in D. mortchaensis   ), absence of cross-striated or roughly punctate anterior transverse impression on the pronotum and especially by the much shorter elytra (length/width ratio equal to 1.64–1.65 in D. jelineki   sp. nov. and 1.73–1.82 in D. mortchaensis   ) with deeper and much more roughly punctate striae. The structure of head and stria 8 is similar to D. (D.) chalybeus resli ( Bulirsch, 1996)   , known from the Eastern Mediterranean. Dyschiriodes jelineki   sp. nov. can be distinguished from the latter subspecies by much larger body (3.70 mm in D. jelineki   sp. nov., 2.65–3.45 mm in D. chalybeus resli   ); no cross striae in the anterior transverse impression of the pronotum, laterally more flattened elytra without basal tubercle and more densely and roughly punctate elytral striae. Finally, D. jelineki   sp. nov. can be distinguished from most of the Afrotropical and Oriental species of the D. chalybeus   group sensu FEDORENKO (2000) (= D. bengalensis   group sensu FEDORENKO (1994, 1996)) by having stria 8 strongly weakened at elytral apex.

Distribution. Southern Iran.
