FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LV 1994 p. 321-334 A revision of the West Palaearctic species of Schroederella Enderlein (Diptera: Heleomyzidae) L. Papp and M. Carles-Tolrá A revision of the West Palaearctic species of Schroederella Enderlein (Diptera: Heleomyzidae). Four new species of Schroederella Enderlein, 1920 are described: 5. bifida sp. n. (Spain), S. hispanica sp. n. (Spain), S. hungarica sp. n. and S. minuta sp. n. (Hungary) with notes on the type-species S. iners (Meigen); a redescription of the genus is given with a key for the West Palaearctic species. With 27 original figures. Schroederella Enderlein, 1920 is a genus of the Holarctic heleomyzids: one Nearctic species (S. fuscopicea Gill, 1962) and five East Palaearctic species (see below) have hitherto been known, as well as S. iners (Meigen, 1830), the type-species of the genus, which is widely distributed in the Holarctic (Gill 1962, Gorodkov 1984). In the course of studies on the European species of Heleomyzidae authors found species of Schroederella new to science and so a co-authored paper was decided. The type-specimens of the species described below are deposited in the collection of the Department of Zoology, Hungarian Natural History Museum, Budapest, in Mr Javier Blasco-Zumeta's collection in Pina de Ebro and in Dr Miguel Carles-Tolrá'

s collection in Barcelona. Schroederella Enderlein, 1920 Enderlein, 1920: 298. Type-species: Helomyza iners Meigen, 1830: 37 (aut.). Schroederia Enderlein, 1914: 314, a junior homonym of Schroederia Schmidt, 1911. Type-species: Helomyza iners Meigen, 1830: 37 (mon.). Diagnosis: in general as described by Czerny (1924), keyed by Gorodkov (1970) and Papp (1981) and specifically: flagellomere rounded but not elongate; 2 pairs of ors, anterior pair re- and exclinate, comparatively long, longer than half length of posterior ors, oc, vte, vti, poc all long; arista longer than height of head; 1 pair of very long vibrissa, peristomal hairs comparatively short, no prosternais, \h,2 np, 1 prsut, 1 + 3 de, 1 sa, 2 pa, 1 prsc ac, 2 sc pairs of characteristic setae. 2 pairs of katepisternals (sternopleurals), no microchaetae on anepisternum; mid tibia apicoventrally with at least 2 setae; male hind femur ventrally with 2 complete rows of spiniform setae; costa of wing with long setae; male genitalia with well-developed édita and surstyli, editum bilobed in some species; female cerci with hairs and bristles only. Gorodkov (1962) while describing S. robustella named the cranial process of epandrium as "the process of 9th tergite", later (Gorodkov 1970) as surstylus.
