Material examined.

1 ♂ (holotype), Greece, Crete, Biro, Canea, 1906/11 (Hungarian Natural History Museum, Budapest); 2 ♀ and 4 ♂, Iran, Zabol (31°02'28"N, 61°32'02"E, 482 m A.S.L.), 26.iv.2013, sweeping on Cyperus rotundus (Z. Rahmani leg.) (ENV, ZISP); 7 ♀ and 20 ♂, same locality, 22-24, 26 and 27.iv.2013 (Z. Rahmani leg.) (FAUOZ).

Diagnosis.

This species resembles Indiopius fischeri Samiuddin et Ahmad from India and Indiopius turcmenicus Tobias from Turkmenistan. Indiopius cretensis differs from Indiopius fischeri in has the maxillary palpi as long as head height (0.5 times in Indiopius fischeri ), the first flagellar segment of female 2.55-2.65 times as long as its width (2.1 times in Indiopius fischeri ), and the middle flagellar segments of female 2.25-2.65 times as long as their width (1.5 times in Indiopius fischeri ). Also, Indiopius cretensis differs from Indiopius turcmenicus in having the first flagellar segment of female 2.55-2.65 times as long as its width (3.0 times in Indiopius turcmenicus ), the middle flagellar segments of female 2.25-2.65 times as long as their width (2.0 times in Indiopius turcmenicus ), the first metasomal tergite 1.0-1.1 times as long as its apical width (0.8 times in Indiopius turcmenicus ), and vein 1cu-a postfurcal (interstitial in Indiopius turcmenicus ).

Description.

Female (first record). Body length 1.0-1.1 mm; fore wing length 1.4-1.5 mm.

Head. In dorsal view, 2.0 times as wide as median length, 1.4 times as wide as mesoscutum, smooth, with rounded temples behind eyes. Eye in lateral view 1.35 times as high as wide and twice as wide as temple in middle. POL 2.6 times OD; OOL 3.45 times OD. Face 1.25 times as wide as high; inner margins of eyes subparallel. Clypeus 3.35 times as wide as high, slightly curved ventrally. Mandible narrow, weakly and evenly widened towards base; upper tooth longer than lower tooth. Maxillary palpi as long as head height. Antenna thick, 18-segmented. Scape 1.40-1.45 times as long as maximum width, about twice as long as pedicel. First flagellar segment 2.55-2.65 times as long as its apical width, 1.15-1.20 times as long as second segment; second segment 2.6-2.7 times as long as its maximum width. Third to ninth flagellar segments 2.55-2.65 times and tenth to sixteenth segments 2.25-2.30 times as long as their maximum width.

Mesosoma. In lateral view, 1.05 times as long as high. Mesoscutum 0.75-0.80 times as long as its maximum width. Notauli mainly absent, finely developed on vertical anterior part. Mesoscutal pit absent. Prescutellar depression with numerous carinae. Precoxal suture present, very shallow, not reaching anterior and posterior margins of mesopleuron. Posterior mesopleural furrow smooth. Propodeum completely smooth. Propodeal spiracles relatively small.

Legs. Hind femur 3.60-3.65 times as long as its maximum width. Hind tibia weakly widened towards apex, about 10.0 times as long as its maximum subapical width, 1.1 times as long as hind tarsus. First segment of hind tarsus 1.3 times as long as second segment.

Wings. Length of fore wing 2.5 times its maximum width. Pterostigma almost triangular. Vein 1-R1 not reaching wing apex and as long as pterostigma. Veins r, 3-SR and SR1 not differentiated; 1-M straight; cu-a postfurcal, 1-CU1 widened. First subdiscal cell open. CU1b absent. M+CU1 only apically sclerotized. Hind wing 6.5 times as long as its maximum width; vein cu-a absent.

Metasoma. Distinctly depressed dorso-ventrally, apical segments rather distinctly protruding behind third tergite. First tergite weakly widened towards apex, 1.1 times as long as its apical width, finely rugose but basally smooth. Second tergite largely finely granulate. Third and following tergites smooth. Ovipositor 1.05 times as long as first tergite, 0.65 times as long as hind femur.

Colour. Body and legs uniformly brown to dark brown, second tergite yellowish brown. Wings hyaline. Pterostigma brown.

Male. Body length 1.4-1.5 mm; fore wing length 1.5 mm. First flagellar segment 2.7-2.8 times and second segment 2.5 times as long as their width accordingly. Third to sixteenth flagellar segments 2.20-2.75 times as long as their width. Otherwise similar to female.
