Lathrolestes lucidulus ( Holmgren, 1857)

70–73.

Perilissus lucidulus Holmgren, 1857: 127 . Lectotype ♀, NHRS [examined, NHRS-HEVA000002030]. Type locality: Sweden (Anneberg, Småland).

Material. 1♂, FINLAND, Turku, Paattinen, 627.24, 16.ix.1968, leg. R.Jussila, ZMUT; 2♀, 2♂, SWEDEN, Norrbotten, Luleå, NHRS; 1♀, SWEDEN, Norrbotten, Pajala kommun, Vasikkavuoma, N67°13.778’, E23°11.200’ (=TrapID 49) 22.viii–14.ix.2003 (=coll. event ID 709), leg. SMTP, NHRS.

Diagnosis. This species differs from other species of the genus by the following character states: 1) face strongly convex, 2) clypeus strongly projecting, concave, 3) occipital carina incomplete dorsally, 4) epomiae present, 5) claws not pectinate 6) metasomal tergites with very narrow yellow margin, 7) hypopigium trangle, black, with hind margin more or less broadly yellow, 8) ovipositor very short, 9) parameres narrow.

Distribution. Finland, Germany, Poland, Russia (Chita Oblast, Khabarovsky Kray, Ussuriysky Kray), Sweden, Turkey.

Comments. This species is described by females only as diagnosing males is difficult. Examined material suggests that the proposed males of this species are similar to L. saliceti ( Fig. 106, 107 ), but the latter has a rhombic and open areolet. In females L. lucidulus is rather similar with L. occultor Aubert, 1991 described from France. But L. occultor has no defined yellow stripes on hind margin of tergites and last sternite (photo of type specimen of L. occultor Aubert, 1991 can be accessed from https://drive.google.com/folderview?id=0BxXMktnC3Ub2SWlHVUl kSkhvQ0U&usp=sharing).
