Anisocentropus (Anisocentropus) brevipennis , new diagnostic species cluster

This diagnostic species-cluster belongs to the Anisocentropus latifascia diagnostic species-group in the subgenus Anisocentropus (Anisocentropus) . The discrimination of the A. brevipennis diagnostic species-cluster is based on the presence of an intermediate shape of the gonocoxites and the lateral flank on the posterior margins of segment IX. The short body of the gonocoxites has a slender, digitate process on its apicodorsal corner in lateral view. This elongated process is longer and more complex in the Oriental member of the subgenus. The posterior margins of segment IX have a lateral flank usually being less developed in species in this diagnostic species-cluster than in other species. The members in the diagnostic species-cluster have a shortened additional flank, while there has been a loss of the flank in other species of the subgenus, also lacking in other subgenera. In the Anisocentropus latifasciata diagnostic species-group many species have an elongate apicodorsal corner forming a digitate process, like in A. fulgidus and A. io; and more advanced in A. maclachlani and A. mjoebergi . These species have a completely developed lateral flank. In the A. brevipennis diagnostic species-cluster, the digitate process is elongated, and the lateral flank short and partly reduced. Several species in the diagnostic species-cluster form intermediate forms. The species are recorded from the Afrotropical, Oriental and Australian Regions, and comprise the following species: A. brevipennis Ulmer, 1906 (Borneo) , A. hoisat , new species ( Laos), A. maralus , new species ( Malaysia), A. semiflavus Banks, 1939 ( Australia) , A. thinlin , new species ( Laos), A. valgus Neboiss, 1980 ( Australia) and A. voeltzkowi Ulmer, 1909 ( Madagascar) .
