The type specimens of Subboriomyia fusca Steinmann, 1967 and Wesmaelius ignoratus Steinmann, 1967 (Planipennia: Hemerobiidae) By Gy. Sziráki (Received August 15, 1991) The type specimens of Subboriomyia fusca Steinmann, 1967 and Wesmaelius ignoratus Steinmann, 1967 (Planipennia, Hemerobiidae). - Examinations carried out showed that the holotype of Subboriomyia fusca Steinmann, 1967 is a female exemplar of Wesmaelius subnebulosus (Stephens, 1836). Consequently, the monotypical genus Subboriomyia Steinmann, 1967 is a junior synonym of Wesmaelius Krüger, 1922. The holotype of Wesmaelius ignoratus Sleinmann, 1967 is a female exemplar of Hemerobius kitescens Fabricius, 1793. The hemerobiid genus Subboriomyia together with the species Subboriomyia fusca and Wesmaelius ignoratus was described by H Steinmann from Hungary (Steinmann, 1967). In the European monograph of Neuroptera (Aspöck, Aspöck et Holzel, 1980) S. fusca and W. ignoratus was treated as species "described erroneously for Europe", because as it was stated - "According to author's verbal communication [both species] was described from memory; type material does not exist". On the other hand, in a recent world catalogue of Hemerobiidae (Monserrat, 1990) both above-mentioned species, as well as the genus Subboriomyia are listed as valid taxa. In the course of the revision of Neuroptera collection of the Hungarian Natural History Museum, Budapest holotypes of Subboriomyia fusca and Wesmaelius ignoratus were found. It was made clear that none of them represents a distinct species. The female exemplar - labelled as: "Subboriomyia gen. et sp. nov., det. Dr. H. Steinmann - holotype - Budapest, Budatétény, 16. 8. 1962, light trap" - is a specimen of Wesmaelius subnebulosus (Stephens) with typical subgenitale and gonapophyses posteriores (Fig. 1). Fore wing only with 2 side branches arising from the stem of RURs (while usually with 3), but this alteration is not extremely rare. (However, on the left fore wing there is a rare asymmetrical aberration: the basal cross-vein between MA and MP is absent.) The female exemplar - labelled as: "Wesmaelius ignoratus sp. nov., det. Dr. R Steinmann, 1964 - holotype - Sopron, Fáber-rét, 25. 8. 1963, light trap" - is a specimen of Hemerobius lutescens Fabricius, with a typical wing pattern. However, on the fore wings 4 side branches arise from the stem of Rl + Rs (Fig. 2), i.e. R4 and R5 in this case do not merge into each other. (Terminology of the wing venation has been adopted from Kevan et Klimaszewski (1987).
