1 ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus The Scientific Results of the Hungarian Soil Zoological Expedition to the Brazzaville-Congo 45. Pygostenini and Euaesthetinae (Coleoptera: Staphylinidae) by D. H. KISTNER & H. R. JACOBSON, Chico, California* The purpose of this paper is to report the species of Pygostenini and Euaesthetinae collected in the Congo (Brazzaville) by the Hungarian Soil Zoological Expedition. Also included are descriptions of 2 new species, genus Typhloponemys REY. All of the species reported here belong to groups which have been revised recently. The Pygostenini were revised by KISTNER, (1958); the genus Stenaesthetus by KISTNER (1962a), TURELLUS by KISTNER (1961 and 1962a), Edaphus by KISTNER (1962b), Octavius of Africa by KISTNER (1960), and Schatzmayrina by KISTNER (1961). No further bibliographic: citation will be given if the species cited are included in these revisions. Measurements are herein given in mm and are taken as described by KISTNER (1958). We wish to thank Dr. KASZAB, General Director of the Hungarian Natural Histoiy Museum (NHM), for the privilege of studying these interesting specimens. Holotypes of new species and unique specimens are all deposited in the above museum. If more than 1 specimen was available for study, duplicates have been placed in the collection of the senior author. We thank WILLIAM BLACKBURN, DANIELA DAVISON, JAN FISCHER, DAVID HARWOOD, ELAINE MCNICHOLS, JANIS SHELHORN, and ANGELA VENDSEL, all Shinner Assistants, Chico State College, for help on this study.

2 172 D. H. K I S T N E R & H. R. JACOBSON Typhloponemys kaszabi sp. n. (Fig. 1, 2) The absence of the 2 middle macrochaetaxy of abdominal tergite I I I, indicates a close relationship to T. rufotestaceus (fauveli group). I t is distinguished from t h a t species and all others by the shape of spermatheea and the male genitalia. Colour yellowish brown throughout. Dorsal surface of elytra, pronotum, and head smooth and shiny. Elytra covered w i t h yellow setae. Pronotum more sparsely covered. Macrochaetotaxy of abdominal tergites I I - V I I I : 2, 2, 4, 4, 4, 4, 0. Macro chaetotaxy of abdominal tergite I X as follows : dorsal lateral part, 6, anterior chaetae small and yellow; median dorsolateral part, 4; ventrolateral part, 4; median lobe, 7. Spermatheea shaped as in Fig. 2. Median lobe of male genitalia shaped as i n Fig. 1.

Typhloponemys endroedyi sp. n. (Fig. 3, 4) Distinguished from all other species, including T. leleupi K I S T N E R (megalophthalmus group) to which i t is most closely related, by the shape of the spermatheea. Colour yellowish brown, head slightly darker. Dorsal surface of head, prono tum, and elytra smooth and shiny. Macrochaetotaxy of abdominal tergites I I - V I I I : 2, 4, 4, 4, 4, 4, 0. Middle chaetae of tergites I I I and I V very small.

Note: The male genitalia of this species show a great similarity to that of T. leleupi. The reduced size of the middle chaetae of tergites I I I and I V also supports this relationship.
