Apomecyna balochicus sp. nov.

( Fig.2 )

Type locality. Pakistan, Balochistan Province, Bela , District. Lasbela

Type specimen.: Holotype male, pinned, Original label: “ Pakistan, Balochistan Province, Bela, District Lasbela, 12.vi.2022, Collector, Zubair Ahmed”, “ HOLOTYPE / Apomecyna balochicus / Ahmed and Barševskis” [handwritten label] ( FUUZM). 26° 13' 37.56" N, 66° 18' 39.96

Description. Measurement: body length12.00 mm.

Coloration: Body black, covered with grey to light grey patches and pubescence.

Body elongate, subcylindrical, slightly flattened, grey. Head depressed between eyes with a median line, clypeus with sinuate anterior margin. Antennal tubercles projected. Basal antennomere narrow proximally, gradually broadened distally, antennomere 2 small, slender, antennomere

68 & Basak 1992). Additionally, both species have sister relationship like elytra dark brown; antennae hardly extending up to middle of elytra but separated by elytra with pale reddish brown hairs, elytra obliquely truncated apically; 3 rd and 4 th antennal segments apically and rest of the segments dark brown, 3 rd and 4 th segments combined length longer than 5 th and rest of segments combined pronotum with basal gray small patch in A. histrio while elytra with greyish hairs, elytra conically and rounded apex; all antennal segments dark brown, 3 rd and 4 th segments combined shorter than 5 th and rest of segments combined and pronotum with all margins with grey narrow patch in A. minor sp.n.

Etymology. Apomecyna minor – The name of the new species alludes to the small body.

3 slightly curved, longer (1.3mm) than 4 th segment (1.0mm), apical antennomere small, bent at upper side, conically narrowed.

Pronotum with anterior margin narrower than posterior margin, feeble explanate apically, lateral margin oblique anterior, then rounded, deflected at base, posteriolateral margins angulate at both sides, disc convex, covered with dense hairs, coarse punctations, median line white, scutellum triangularly rounded with two bunch of pale white hairs lobately oblique.

Elytra with shoulders straight, apico-lateral margin feebly explanate, strial margins with coarse punctures, sparsely dense covered by dingy brown pubescence, each elytron with two pairs gray patches mediolateral, premedian patch oblique, cylindrical, postmedian patch with distinct three broad dot like patch, apices conically produced. Mesosternal process broad, elongate, sinuate at base. Metasternum divided at base, with groove. 1st ventrite broadly triangular, elongate, ventrites black, dense, with sparse setation, lateral margins with series of white dense patches of hairs, with some coarse punctures. Legs with fore femora shorter than meso- and metafemora, tibiae short, slender, broadened at apex.

Male genitalia: Fig. 2 (c – g).

69 Differential diagnosis: Apomecyna balochicus sp.nov. is similar to A. fallaciosa Breuning by the body appearance, but the entire body punctation is not deep and coarse than that in A. fallaciosa . Additionally, pronotum with a median white patch line; scutellum with buch of pale pubescence; elytral patches mediolateral and away from sutural margin; aedeagus with parameres shorter than median lobe, position of median hanging band-like sclerites is right angle, connected; basal plate quadrate shaped, as long as broad; lateral margin of ventrites with pale yellow spotted marked in A. balochicus sp.n while pronotum without a median patch line; scutellum have not such pubescence; elytral patches dorso-lateral and near to sutural margin; aedeagus with parameres slightly longer than median lobe, basal plate wider than long, position of median hanging band-like sclerites curved, separate; lateral margins of ventrites without such spotted mark in A. fallaciosa .

Etymology: The species name is derived from the name of the province of Baluchistan where it was found.
