Papp, J.: Two new Biosteres Först. species from the Carpathian Basin (Central Europe) (Hymenoptera, Braconidae: Opiinae)
Fore wing somewhat longer than body. Stigma (Fig. 9) 5.5 times as long as wide, emitting radial vein somewhat proximally from its middle, rl half as long as width of stigma, rl slightly longer than cuqul, r3 somewhat more than twice as long as rl and reaches tip of wing. n. rec. interstitial, distinctly shorter than d. Abdomen almost as long as head and thorax together, more or less broader than thorax. First tergite one-third longer than wide at hind (36 : 26, X 100, Fig. 5), from base to spiracle more broadening than behind spiracle, with two converging keels merging behind into the rather longitudinal rugorugulosity. Further tergites polished. Ovipositor sheath (in lateral view) nearly as long as abdomen. Body black. Clypeus, mandible (except its black apex), tegula and legs brownish yellow. Palpi rather dirty brownish yellow. Sternites rusty brown. Antenna black, scape and pedicel below brownish yellow. Wings hyaline, veins opaque brown. çf and host unknown. Localities: 1. Hungary, Nagykovácsi, Remetehegy, 25 April 1957, 2 $ (1 9 holotype, 1 9 paratype), leg. MIHÁLYI. — 2. Yugoslavia, Voyvodina, Fruska Gora, Sremska Kamenica, 300 m, 1-2 May 1971, 1 9 (paratype), leg. PAPP and HORVATOVICH (NO. 1). Holotype and paratypes deposited in the Hungarian Natural History Museum, Budapest; Hym. Typ. No. 2811 (holotype), 2812 and 2815 (paratypes). Remark — 1. Holotype being not in a perfect conditions: its left flagellum broken. Paratype also slightly damaged: distal end of its fore right wing shortly torn, and distal quarter of its fore and hind right wings somewhat creased. — 2. The paratype from Yugoslavia (Sremska Kamenica) was named by me in 1972 as B. blandus HAL. (PAPP 1973). Though rl is somewhat longer tha cuqul, the specimen, considering its habitus, should be referred to the genus Biosteres. Furthermore, its recurrent vein (n. rec.) is postfurcal, and perhaps this form of vein-junction represents the normal form? Though the new species extremely resembles Biosteres (Chilotrichia) blandus (HALIDAY, 1837) (Palaearctic Region), it is easy to separate them on the basis of clear-cut specific features given below in a tabular form : B. advectus sp. n. B. blandus (HAL.) 1. Head (in dorsal view) somewhat less trans- 1. Head somewhat more transverse, behind eye verse, behind eye outline of temple less con- outline of temple more constricted (Fig. 6). stricted (Fig. 1). 2. Clypeus semicircular, twice wider than high. 2. Clypeus thrice wider than high. 3. Temple (in lateral view) somewhat broader 3. Temple less broad than width of eye (15-14:18 than width of eye (18 : 15, Fig. 3). Fig. 7). 4. Radial vein issuing close before middle of 4. Radial vein issuing from middle of stigma stigma and reaching tip of wing, n. rec. inter- and rather approaching tip of wing, n. rec. stitial (Fig. 9). postfurcal (Fig. 10). Fig. 9.
