Yotvata (Yotvata) farsiana sp. nov.

( Figs. 28A , 24A–J )

Type material. HOLOTYPE: J, IRAN: FARS: Fasa, Mianjangal , 17.–18.vi.2008 . PARATYPES: IRAN: FARS: J, Fasa , Mianjangal, 17.–18.vi.2008 ; J, Maharlu, 17.–18.vi.2002. The types will be deposited at the National Museums and Galleries of Wales (Cardiff, United Kingdom) .

Description. Length 2.75–3.0 mm (J).

Colouration. Whitish grey with relatively sparse and faint dark dotting ( Fig. 28A ). Tylus with a few dots, lateral margins of vertex with transverse red stripes, base of vertex with red spot close to eyes; eyes greyish brown. Antennae whitish yellow, reddish apical spot on antennomere 1 and subbasal and subapical spots on antennomere 2 faint. Rostrum yellowish, apically darkened. Pronotum with a few dark spots. Base of scutellum black with narrow pale median stripe, apical part with a few minute dark dots. Hemelytra pale, clavus and corium with only a few minute dark dots, lateral margins of corium with some minute red dots, interoapical angle of corium with a black spot; cuneus immaculate, only middle of inner margin with a small black dot; membranes dark greyish brown. Ventral body surface largely greyish. Thorax with brown or red dots. Lateral margins of venter also with reddish stripes. Legs whitish yellow, margins of femora with round black spots, black bristles of tibiae arising from small black dots; tarsi somewhat darkened.

Structure. Body about 3× as long as basal width of pronotum. Upper surface with long white pubescence. Head 0.65–0.72× as broad as basal width of pronotum; ocular index 1.17–1.43. Antennae long and gracile, length ratios of antennomeres 6: 24: 12: 10, antennomere 2 1.44–1.61× as long as diatone and 1.04–1.07× as long as basal width of pronotum. Rostrum extending to base of venter. Pronotum 2.3–2.5× as broad as long. Hind tibia about 1.75× as long as basal width of pronotum. Male genitalia as in Fig. 24A–J .

Differential diagnosis. Yotvata farsiana sp. nov. is related to Y. picticornis (Horváth, 1913) . Yotvata picticornis ( Fig. 28B ) differs from the new species in the following characters: more abundant red pattern on the dorsal surface; antennomeres 1 and 2 with clear red spots; basal part of scutellum red; clavus, corium and cuneus with red spots, middle of corium sometimes with a larger red spot; eyes larger, ocular index 0.8–0.9 (J), 1.33–1.90 (♀); antennae shorter, antennomere 2 0.8–0.9× as long as basal width of pronotum; male genitalia as in Fig. 25F–J. A key to the genus Yotvata Linnavuori, 1964 was published by LINNAVUORI (1993: 197–206).

Habitat. In gardens on the shore of a salt lake.

Etymology. Named after the Fars province.

Distribution. So far known only from two localities in the Fars province in Iran.
