Arachnospila satyrus ( HAUPT, 1930) ( figs 1-9 ) M a t e r i a l e x a m i n e d: 6♀♀ 05.vii.2018 Ziarat, plateau (Golestan), 1♂ 03.vii.2018 Razan

(Mazandaran).

D i s t r i b u t i o n i n I r a n: ENAYATNIA et al. (2018).

R e m a r k: The species was described under Psammochares satyrus HAUPT, 1930: 590, from Mazandaran province and was never collected later. A. satyrus lacks in the revision of Arachnospila s.str. by LELEJ & LOKTIONOV (2011) as well as the closely related A. ionica (WOLF, 1965), described from Greece. The male was unknown and is described here for the first time.

D i a g n o s i s: The female of A. satyrus is unique in the A. rufa species group (subgenus Arachnospila KINCAID sensu LELEJ & LOKTIONOV (2011)) by the following character combination: Foretarsomere with 4 spines, apical spine longer than second tarsal segment, apical clypeal margin straight, abdomen all black. For a more detailed description see HAUPT (1930). A. ionica shares the long foretarsal spines and the straight apical clypeal margin with A. satyrus , and has tergites I and II red. AS 3 is shorter in A. ionica (0.7x as long as ocular distance near ocelli), compared to A. satyrus (0.8x as long as ocular distance near ocelli). The females of A. satyrus measure 14-16 mm.

The male is characterized by a short propodeum and by an all black abdomen. Medial keel of S8 is relatively flat compared with related species, and bears some erect setae.

D e s c r i p t i o n m a l e: Body length 14.0 mm. All black species including setae. Basal half of mandible, clypeus laterally and lower half of face with silver, appressed pubescence. Wings greyish infumate with darker apical zone. Head, forecoxa, most parts of mesosoma and T1 basally and laterally with long pilosity. Longest setae of frons as long as scape, remaining pilosity somewhat shorter. AS 3 somewhat longer than AS 1. Propodeum short, similar to A. sogdianoides . S6 apcially deeply U-shaped emarginated. Keel of S8 flat, with some short erect setae. Genital see fig. 7 , SGP see fig. 8 and 9.

H a b i t a t: Most specimens were collected in a mountain steppe with flowering Euphorbia spec. (see fig. 19).
