Es wird das isolierte Vorkommen einer Acalles micros-Population in einem Buchenwald des Niederbergischen Landes ("Vogelsangbachtal": Deutschland / Kreis Mettmann, NRW) beschrieben. Die Nordgrenze dieser vor allem aus dem nördlichen Mittelmeeraum bekannten, wärmeliebenden Art lag bisher 300 km weiter südlich (Rheinland-Pfalz, Taben-Rodt). Neben einer Differentialdiagnose der Arten Acalles micros, Acalles lemur und Acalles commutatus werden alle Funddaten und eine westpaläarktische Verbreitungskarte von Acalles micros vorgestellt. [Fig. 1] Das nördlichste, isolierte Reliktvorkommen von Acalles micros, das aufgrund der Nähe zum Rhein "fluvial" und wahrscheinlich "postglazial" (warmzeitlich) entstanden ist, war ursprünglich zweifellos bedeutend größer. Vor allem infolge flächenintensiver Rodungen in historischer Zeit wurde der Lebensraum dieser Buchenwaldart erheblich eingeschränkt.
The new genus Neotrichaphodioides and the new species N. woytkowskii from Peru are described. Aphodius caracanus Balthasar, A. ecuadoriensis Petrovitz, A. forsterianus Balthasar, and A. volxemi Harold are redescribed and figured, and transferred into Neotrichaphodioides, all becoming new combinations. New synonymies of Aphodius martinsi Petrovitz with N. caracanus (Balthasar) and Aphodius squamifer Petrovitz with N. volxemi (Harold) are presented. The lectotype of A. volxemi is here designated.
Besides the two species at present known belonging to the genus Trichonotuloides Balthasar (T. glyptus (Bates) and T. latecrenatus (Bates)), two new Mexican species, T. alfonsinae and T. hansferyi, are herein described (Coleoptera: Scarabaeidae: Aphodiinae). The complete set of fi gures is supplied for all taxa herein dealt with.
Twelve new species are assigned to the genus Otitoma Jousseaume, 1898 in the family Pseudomelatomidae Morrison, 1966 and herein described: O. hadra sp. nov., O. neocaledonica sp. nov., O. rubiginostoma sp. nov and O. tropispira sp. nov. from New Caledonia; O. boucheti sp. nov., O. nereidum sp. nov. and O. sororcula sp. nov. from the Fiji Islands; O. xantholineata sp. nov. from the Solomon to the Fiji Islands; O. crassivaricosa sp. nov. from Fiji to Hiva Oa Island (Marquesas Archipelago); O. philpoppei sp. nov. from the Philippines but also reported from the Fiji Islands; O. elegans sp. nov. from the Fiji Islands and O. philippinensis sp. nov. from the Philippines. New data on O. carnicolor (Hervier, 1896) are provided. Otitoma mitra (Kilburn, 1986), from Southern Mozambique, is here considered a synonym of O. cyclophora (Deshayes, 1863). Drillia batjanensis Schepman, 1913, previously assigned to the genus Maoritomella Powell, 1942 in the family Borsoniidae Bellardi, 1875, is here assigned to the genus Otitoma. Photographs of the holotype of Drillia batjanensis are provided for the first time. In addition, color photographs of the type specimens of the following species are provided: Drillia kwandangensis Schepman, 1913, D. timorensis Schepman, 1913 and Mitrellatoma mitra Kilburn, 1986.
