sp. nov.

Dyschiriodes (Eudyschirius) kadleci   sp. nov.

( Figs. 4 View Figs , 10 View Figs , 16 View Figs )

Type locality. India, W Maharashtra state, Bushi Dam env., 4 km S of Lonavala, 500 m a.s.l.

Type material. HOLOTYPE: ♁, ‘INDIA W MAHARASHTRA / st., Bushi Dam env. / 4 km S of Lonavala / 500 m, 12.–15.x.2005 // Dyschiriodes   / ( Eudyschirius   ) / sp. n. / det. D. Fedorenko 2006’ ( NMPC). PARATYPE: INDIA: MAHARASHTRA: ♀, ‘INDIA W MAHARASHTRA / st., Mulshi env. / 40 km W of Pune / 7.–11.x.2005 ’ ( PBPC).

Description. Habitus as in Fig. 4 View Figs ; HT and PT 3.45 mm long. Coloration dark fuliginous, surface with green-bronze lustre; head anteriorly and elytral base slightly lighter, latero-apical area of each elytron with yellowish macula; legs rusty red, antennomere 1 and mouth-parts lighter.

Head. Anterior margin of clypeus with sharp, distinctly protruded lateral lobes, between them almost straight with two very blunt, barely recognisable projections; clypeofrontal area with moderately impressed, short transverse furrow at the level of anterior margin of eyes and with additional irregular and very fine, barely recognisable transverse furrow at the level of posterior half of eye length; facial furrows deep and broad, regularly divergent posteriorly; distance between them narrower than eye length. Surface vaulted, even, smooth, with very fine and sparse micropunctures. Eyes moderately large, strongly convex. Antennae submoniliform.

Pronotum. Strongly convex, outline regularly rounded, not attenuated anteriorly; in HT 1.11 times and in PT 1.05 times as wide as long, in HT 1.34 times and in PT 1.35 times as wide as head; widest in anterior two thirds of its length. Anterior angles very blunt, posterior ones moderately broadly rounded. Anterior transverse impression deep, roughly and sparsely punctate, without cross striae; median line moderately deep apically, much finer on disc; lateral channel moderately broad, reflexed lateral margin extended markedly beyond posterior setiferous puncture. Surface mirror-like, shiny, with very fine micropunctures.

Elytra. Convex, slightly ovate, in HT 1.70 times and in PT 1.67 times as long as wide, in both HT and PT 1.25 times as wide as pronotum; humeri moderately protruded without humeral teeth; base moderately sloping; outline regularly broadened on sides, broadest slightly behind anterior third; suture not depressed at base. Base without basal border and tubercles; BSP large, deeply connected with stria 1 and indistinctly with stria 2. Striae 1–7 deep along entire length, densely and finely punctate in anterior part; punctation gradually disappearing latero-apically, stria 8 much finer, consisting of 3–5 fine punctures in second third. Intervals distinctly vaulted. Three PHSP, three DSP (in middle of interval 3) and two ASP (in deep apical stria).

Protibia.Apical spine slightly curved downwards but not inwards, as long as apical spur; the latter thin, almost direct; distal marginal tooth large, sharp, proximal one small, very blunt.

Aedeagus. Length 0.61 mm in HT, lower margin of median lobe almost straight ( Figs. 10 View Figs and 16 View Figs ). Apical lamella long, narrow, asymmetric ( Fig. 16 View Figs ). Paramere with one seta.

Differential diagnosis. Dyschiriodes kadleci   sp. nov. belongs to the D. orientalis   group (sensu FEDORENKO 1996, 1997b). It can be distinguished from the most similar D. (Eudyschirius) nitens (Putzeys, 1878)   , to date the only known species of the group with elytral striae not shortened apically, by its much larger size (3.45 mm in D. kadleci   sp. nov., 2.40–2.80 mm in D. nitens   ), less infuscate apices of the antennae, more sloping elytral base, finer elytral striae with interval 5 slightly broader than punctures (interval distinctly narrower in D. nitens   ), very fine stria 8 (very deep in D. nitens   ) and different shape of the median lobe of the aedeagus (compare Figs. 2.3 and 3.1 View Figs in FEDORENKO (1997b) for D. nitens   ). It is easily distinguished from the remaining members of the D. orientalis   group by the equally impressed elytral striae, which become shallower apically in the other species.

Etymology. Named in commemoration of my late friend Stanislav Kadlec, a specialist in Cerambycidae   , who passed away recently in 2008.

Distribution. India (western Maharashtra).
