The case of Holopyga gogorzae Trautmann, 1926 and revision of the H. miranda group (Hymenoptera, Chrysididae) Author Rosa, Paolo Author Pavesi, Maurizio text Natural History Sciences 2020 2020-11-18 7 2 39 56 http://dx.doi.org/10.4081/nhs.2020.474 journal article 300325 10.4081/nhs.2020.474 a3367a5d-a311-4469-a945-88f3e37b3ae1 2385-0922 12753933 HOLOPYGA MIRANDA SPECIES GROUP Diagnosis. The Holopyga miranda group, including relatively small-sized species, is characterised by: tarsal claws apically bifid, with a very small submedian tooth, and a second, almost vestigial denticle, the latter bearing a long seta ( Fig. 14 F-H); body dorsally entirely metallic red, at most ( H. lucens ) with weak greenish reflections, yet never with well delimited green to blue areas; mesosoma ventrally non-metallic black, at most with weak bronze reflections, in West Mediterranean species, bright metallic only in the East Mediterranean H. enslini Linsenmaier, 1959 and the Central Asian H. lucens Rosa, 2018 ; punctation on metasoma dense, with small punctures; male genitalia as usual in the genus, drop-like, basally rounded, and with sharply pointed gonocoxae, unlike those, unmodified (i.e. Hedychridium -like), of the otherwise similar H. fervida group (see e.g. H. gogorzae , Fig. 2C ); wings darkened. The peculiar, apically bifid tarsal claws and the ventrally black mesosoma are features shared with H. fervida group; yet the mesoscutellar punctation and the shape of genitalia for the moment allow a separation, possibly artificial, from each other. The importance of tarsal claws in the systematics of Chrysididae has long been recognized, and emphasized by Kimsey & Bohart (1991) . However, at least H. fervida was found not to genetically differ from other European Holopyga ( Pauli et al ., 2019 ) , therefore not to be included in a separate genus. Species included. Holopyga calida Linsenmaier, 1951 ; H. enslini Linsenmaier, 1959 ; H. lucens Rosa, 2018 ; H. mattheyi Linsenmaier, 1959 ; H. miranda Abeille de Perrin, 1878 ; H. naefi Linsenmaier, 1959 ; H. tussaci Linsenmaier, 1999 .
