Papp, J.: First synopsis of the species of obscurator species-group, genus Bracon, subgenus Glabrobracon (Hymenoptera: Braconidae, Braconinae)

as follows: Asiabracon TOBIAS, Bracon FABRICIUS s. str. (=Striobracon FAHRINGER), Cyanopterobracon TOBIAS, Foveobracon TOBIAS, Glabrobracon (FAHRINGER) TOBIAS, Lucobracon (FAHRINGER) TOBIAS, Orthobracon (FAHRINGER) TOBIAS, Pilibracon TOBIAS, Rostrobracon TOBIAS and Sculptobracon TOBIAS. The subgenus Glabrobracon (FAHRINGER, 1927) TOBIAS, 1957 was first divided in species-groups by TOBIAS (1958), who separated thirteen groups comprising the species distributed in the former USSR: ahngeri, angustiventris, anthracinus, colpophorus, discoideus, fumipennis, jaroshevskyi, larvicida, nigripilosus, picticornis, planinotus, tekkensis and variator species-groups. In the key to the Bracon species of the European part of the former USSR TOBIAS (1986: 114-149) has not separate his species-groups within the subgenera. To the Glabrobracon species of the Carpathian Basin (or historical Hungary) PAPP (1966) selected the following eight species-groups: anthracinus, discoideus, dolichurus, obscurator, piger, terebella, tshitsherini and variator species-groups. The ninth group, i.e. urinator-group, was raised to subgeneric rank under the name Cyanopterobracon by TOBIAS back in 1957. Recently BEYARSLAN & FISCHER (1990) retained seven species-groups to the Palaearctic species of the subgenus Glabrobracon: abscissor, anthracinus, caudatus, conjugellae, jaroshevskyi, osculator and piger species-groups. Motivated by taxonomic practice and applicability it seems necessary to sustain the obscurator species-group within the subgenus Glabrobracon. Fifteen Bracon species are ranged in this group: B. admotus sp. n., B. arcuatus THOMSON, B. claripennis THOMSON, B. colpophorus WESMAEL, B. instabilis MARSHALL, B. kopelkei sp. n., B. longulus THOMSON, B. marshalli SZÉPLIGETI, B. momphae PAPP, B. obscurator NEES, B. pachyceri QUINTARET, B. pallicarpus THOMSON, B. parvicornis THOMSON, B. parvulus WESMAEL and B. pauris BEYARSLAN. Five of these species were included in BEYARSLAN & FISCHER'S species-groups, they are as follows (the respective species-groups are given in parenthesis): B. claripennis THOMSON (abscissor-gronp), B. longulus THOMSON and B. obscurator NEES (conjugellae-gvoup), B. pachyceri QUINTARET and B. parvicornis THOMSON (piger-gvonp). The species of the obscurator-group are characterized by the following features: 1.) Ground colour of body is black or brownish black, legs are usually dark coloured; less usually with more or less light (brownish, brownish yellow, yellow) colour; body exceptionally with light colour pattern. 2.) Number of antennomeres 15-28-30(-33), flagellomeres longer than broad. 3.) Ovipositor sheath usually about as long as hind tibia or hind tibia + basitarsus combined, sometimes shorter, exceptionally (distinctly) longer.
