NOTES. Studying the type material from Strobl´s collection, Morge and Negrobov [1981] placed Gymnopternus (Hypophyllus) quadrifilatus Strobl, 1899 in synonymy with Hercostomus parvilamellatus . Nevertheless, figures provid- ed by the authors and our material examined (see below) have shown that the name G. quadrifilatus is a synonym of Hercostomus parvulus Parent, 1927 . The latter species is very close to H. parvilamellatus , but well differing in characters provided by Parent [1938]. The morphology of both species corresponds entirely with the generic concept of Sybistroma as described by Brooks [2005]. Their males are lacking modified antennae, but can be distinguished by the possession of greatly elongated and setose apicoventral epandrial lobes; the antenna has enlarged scape, reduced pedicel; the wing has weak sinuous anterior bend before middle; the hypopygium has basiventral epandrial lobes elongate and digitiform, shifted ventrally and lying beside hypandrium. Parent [1938] included “ Russia ” into the area of the species. However, we do not know papers with original material from this country. S. parvilamellata was reported from Belgium, France, Germany, Italy, Spain and UK.
DIAGNOSIS. S. parvilamellata and S. parvula are close to S. lorifera (Mik, 1878) , differing from the latter in non-thickened antennal stylus and relatively short apicoventral epandrial lobe. S. parvilamellata differs from S. parvula in antennal stylus with basal segment slightly shorter than apical segment; cercus elbowed, yellow, with long apical setae; phallus expanded distally (see key below).
