Papp, L.: Notes on some Becker's types (Diptera, Carnidae and Risidae fam. n.)

186 L. PAPP and long, the surstylus of glaberrima emitting more bristles, scarcely widening in the middle and its medially bending subapical bristle is shorter and thin. Body length of lectotype: 1.48 mm, length of wing 1.35 mm, width of wing 0.53 mm. Lectotype male: „Korsika, 55570. VI" (Becker's hand-writing), below on fading red label, printed „Typus", under this a label in Becker's hand-writing:

,,glaberrima BECK." — Paralectotype female : „Korsika 55570" (Becker's hand-writing), below on fading red label, printed „Typus". No other label on paralectotype-specimen. Thus, it is concluded that Meoneura glaberrima BECKER, 1910 is an independent, valid species, its closest relatives are M

. neglecta COLLIN and an undescribed species from Tunisia (Gafsa, BÍRÓ, 1903, 3 ex. in the collection of the Hungarian Natural History Museum, Budapest). Meoneura prima (BECKER, 1903) sp. val. Psalidotus primus BECKER, 1903 Mitt. zool. Mus. Berlin, 2: 192, Taf. 4 e, Fig. 89-91. Lectotype male. A somewhat immature specimen, legs crumpled, otherwise entirely intact, except left basal scutcllar bristle which is broken off and the 2 apical scutellar bristles broken in half. Fore 1 /3 of frons reddish yellow, frontal triangle short, but reaching over middle of frons, 3 pairs of bristle in genal angle approximately of same length. Thorax black, covered in moderately strong brownish grey j^ruinosity. 3 pairs of dorsocentral bristles present. Front femur bearing only 1 strong posteroventral bristle. Legs wholly black, tarsi, especially metatarsi very long and thin, thus, tarsi always longer than tibiae. Wing displays no specific characteristic. 1 made a preparation of the abdomen on a small celluloid plate embedded in Canada-balsam, covered with another piece of celluloid plate. The genitalia well corresponds with the figures given by COLLIN (1937: Fig. l)andSABROSKY (1959, Ann. Ent. Soc. Amer., 52: 18, 22, fig. 5) to depict seducta Coll. : genital vault large, surstyli long, slender, slightly spatulate, lamella wide and comparatively short with many long, curved, whitish transparent hairs, visible even when genitalia retracted. Body length: lectotype male: 1.6 mm, paralectotype Ç Ç : 1.92, 1.60 mm. Wing length of lectotype 1.37 mm, width 0.56 mm. Lectotype male: "Kairo, 44388, XL" (Becker's hand-writing), below on fading red label, printed "Typus". Paralectotypes

: 1 9 : "Kairo, III., 44728", "Typus", "•Psalidotus primus BECK." det. BECK.; 1 9 : "Kairo, IL, 44388", "Typus". In his description BECKER wrote "Mehrere Exemplare aus Kairo, Fayûm. November und März." However, his collection included no specimens from Fayûm which I examined. Other specimens (not types) of his collection: 11 ex.: "Athen IV, 49919". BECKER described it as a new genus and species in 1903 (1. c. p. 191). In the same year HENDEL synonymized the genus (Wien. Ent. Ztschr., 22: 251). Somewhat later BECKER (1905, Kat. pal. Dipt., 4: 239) listed his primus as a synonym of Meoneura obscurella (FALLÉN, 1823). COLLIN followed in BECKER'S footsteps without studying the type, accepting the original author's own synonymization. HENNIG (1937) also considered primus as a synonym of obscurella, though he had an opportunity to study the types. But he accepted the obscurella species on a much broader platform than it is the case today. In his work under Textfig. 68.B. he gave the drawing of male surstylus of primus on the basis of specimens originating from Corsica, and he said: "subspec. von Korsika, "Wahrscheinlich handelt es sich bei diesen Tieren um eine schwach differenzierte korsikanische Rasse." Finally, COLLIN (1937) in England (Grasholm Is., Pembrokeshire) also found some specimens of this species and described them under the name of Meoneura seducta. Consequently, Meoneura seducta COLLIN, 1937 is a new junior synonym of Meoneura prima (BECKER, 1903).
