Choeras tiro (Reinhard, 1880)

(Figs 7 a–g)

Material: Guilan province: Ghazichak (36°45′52.62″ N, 50°20′01.08″ E, 1787m a.s.l.) , 14.vi.2010, 2♀ (TMUC), 2♀ (CNC); 22.vi.2010, 2♀ (TMUC); 28.vi.2010, 7♀ (TMUC); Qazvin province: Zereshk Road (36°25′23.88″ N, 50°06′37.68″ E, 1926m a.s.l.) , 06.vii.2011, 1♀ (TMUC) .

Diagnosis: Pterostigma with conspicuous yellow spot basally (Fig. 7f); T1 and T2 parallel- or sub parallelsided and black; T3/T2 length: 1.50–1.60 (Fig. 7g); anterodorsal corner of mesopleuron black; metacoxa black, sometimes apically yellow; metafemur with combination of black and yellow marks (Fig. 7d). Body length without ovipositor: 3.40 mm.

Notes: Some specimens of our collection differ by having smaller size (body length: 2.60 mm) and propodeum with larger smooth area between median and lateral rugosity; vein 3SR in fore wing not distinct. In other specimens, all characters with the exception of colouration is similar to tiro (i.e., T1 and T2 brown; anterodorsal corner of mesopleuron reddish brown to brown; metacoxa reddish yellow to yellow; metafemur yellow or reddishyellow, sometimes apically with dark spot). We consider these differences as intrapopulation variations of C. tiro .
