Zanchius gurbandicus sp. nov.

( Figs. 2A–E , 28C )

Zanchius breviceps (misidentification): LINNAVUORI (2004: 93), LINNAVUORI (2009: 27) .

Type material. HOLOTYPE: J, IRAN: HORMOZGAN: Gurband , 26.iii.–2.iv.2001 . PARATYPES: IRAN: HORMOZGAN: Gurband, 2JJ 2♀♀, 26.iii.–2.iv.2001 . KHUZESTAN: Behbahan, 1J, 27.–28.iv.2007 ; Shadegan, 1♀, 9.–10.vi.2008; Zeydoon, 1J, 26.–28.iv.2007. The types will be deposited at the National Museums and Galleries of Wales (Cardiff, United Kingdom) .

Description. Length 3.25–3.5 mm (J ♀).

Colouration. Whitish yellow ( Fig. 28C ). Eyes greyish brown. Antennae yellow, base and apex of antennomere 1 and extreme apex of antennomere 2 often with faint small red spot. Rostrum pale. Pronotum with faint reddish stripes along lateral margins and at middle. Hemelytra either pale yellowish or pale greenish with pale base; membranes pale with somewhat greenish cells. Legs pale yellow, tarsomeres 3 of all pairs darkened.

Structure. Body 4.3–4.5× as long as basal width of pronotum. Upper surface with pale pubescence. Head 0.7–0.82× as broad as base of pronotum. Ocular index 1.30–1.48 (J), 1.52–1.65 (♀). Antennae gracile, with short adpressed pubescence, length ratios of antennomeres 20: 90: 63: missing (J), 17: 72: 52: 50 (♀), antennomere 1 0.55× (J) or 0.45× (♀) as long as diatone, antennomere 2 2.1–2.25× (J) or 1.92× (♀) as long as diatone and 1.71–1.73× (J) or 1.6× (♀) as long as basal width of pronotum. Rostrum extending to hind coxae. Pronotum 1.9–2.9× (J) or 1.73–1.9× (♀) as broad as long at middle. Male genitalia as in Fig. 2A–E . Left side of pygophore with a long gracile process.

Differential diagnosis. The new species resembles Z. breviceps (Wagner, 1951) (= Z. iranicus Zheng & Liu, 1993 , synonymized by LINNAVUORI (2007)) but is easily distinguished from it and the other species of the genus by the long lateral process of the pygophore. Other genitalic characters are also different.

Habitat. Collected at light in date-palm gardens with rich undergrowth.

Etymology. Named after the type locality.

Distribution. Apparently endemic to the coastal region of the Persian Gulf in Iran. The previous records of Z. breviceps ( LINNAVUORI 2004: 93, 2009: 27) belong to this species. The true Z. breviceps seems to occur only in inner Iran and includes specimens recorded as Z. breviceps from the Fars province ( LINNAVUORI 2004: 93).
