Rédei, D.: A new species of Stirogaster from Iran (Heteroptera: Reduviidae: Stenopodainae)

keel running from base of abdomen to apex of sternite VI. Genital capsule (Figs 8-9) relatively short, wide, superoposterior border wide, flattened, with an anteromedial elevation. Parameres (Figs 13-16) symmetrical, short, stout, curved, apical part with a short anterodorsal tooth. Phallus (Figs 10-12) directed dorsad within genital capsule (Figs 8-9), basal plates greatly fused forming a long, rod-like structure, dorsal connectives enclose a sharp angle, ponticulus basilaris narrow, basal foramen elongated, basal plate struts accompanying dorsal surface of phallosoma, endosoma with 1+1 bladder-shaped, posteriorly narrowing expansions. Etymology - Specific name from Farsi; Ahriman is the name of the supreme spirit of darkness and evil in the ancient Persian mythology. Comparative notes - Stirogaster ahriman sp. n. differs very sharply from most species of Stirogaster by its size and/or the almost uniformly stramineous pronotum (see LlNNAVUORl 1986; MOULET in press). It runs out to couplet 7(8) and 8(7) in the identification key presented by MOULET (in press) for all known Stirogaster, at this point, the user is confronted with the problem that none of the alternative choices fits the specimen. The new species is most similar to S. uvarovi by its general appearance and colouration. However, important differences can be observed between the two species. Based on the original description and figures of S. uvarovi, the most apparent distinctive characters are given in tabular form (Table 1). Table 1. Distinctive characters for Stirogaster ahriman sp. n. and S. uvarovi CHINA, 1934. S. ahriman sp. n., male S. uvarovi CHINA, 1934, male 1. Body smaller (length of holotype 10.3 mm). Body somewhat larger (about 14 mm). 2.
