Revision of the Anaulacaspis species of the Palaearctic region (Coleoptera: Staphylinidae: Aleocharinae).

Abstract

Types and additional material of the falagriine genus Anaulacaspis Ganglbauer, 1895 are revised. Disregarding one name of doubtful identity, 31 species are recognized in the Palaearctic region, twelve of them new: Anaulacaspis convexa spec. nov. (Turkey); A. cristata spec. nov. (North Pakistan); A. eminens spec. nov. (South Iran, Afghanistan); A. excisa spec. nov. (South Iran); A. flavomarginata spec. nov. (Albania, Greece); A. gilva spec. nov. (North Pakistan); A. iberica spec. nov. (Spain); A. pectinata spec. nov. (China: Yunnan); A. pseudonigra spec. nov. (Turkey); A. reticulata spec. nov. (Turkey); A. sinuata spec. nov. (Iran); A. truncata spec. nov. (Iran). One species, A. inexpectata (Fagel, 1969), is of doubtful generic assignment. The genus and the individual species are (re-)described and illustrated. Twelve synonymies are proposed: Anaulacaspis formosa (Rosenhauer, 1856) = A. cirrosa (Fauvel, 1902), syn. n., = A. algirica (Fagel, 1969), syn. n., = A. elkantarensis (Fagel, 1969), syn. n., = A. macra (Fagel, 1969), syn. n., = A. biskrensis (Fagel, 1969), syn. n., = A. andalusiaca (Fagel, 1969), syn. n.; A. gratilla (Erichson, 1839) = A. lutzi (Reitter, 1909), syn. n.; A. naevula (Erichson, 1839) = A. elegans (Cameron, 1944), syn. n., = A. elegansides Newton, 2015, syn. n.; A. nigra (Gravenhorst, 1802) = A. jonica (Bernhauer, 1910), syn. n., = A. anatolica (Fagel, 1969), syn. n., = A. corcyrana (Fagel, 1969), syn. n. Lectotypes are designated for Aleochara nigra Gravenhorst, 1802, A. picea Gravenhorst, 1802, Falagriola lutzi Reitter, 1909, Falagria laeviuscula Eppelsheim, 1880, F. nigerrima Bernhauer, 1908, and F. beesoni Cameron, 1939. Based on morphological characters, the species are assigned to six species groups. Available data on the zoogeography and natural history of the Anaulacaspis species recorded from the Palaearctic region are compiled. The distributions of the genus as a whole and of the individual species are mapped. A catalogue and a key to species are provided.
