Stick insects of Sulawesi, Peleng and the Sula Islands, Indonesia- a review including checklists of species and descriptions of new taxa (Insecta: Phasmatodea) Author Hennemann, Frank H. text Zootaxa 2021 2021-12-06 5073 1 1 189 journal article 10.11646/zootaxa.5073.1.1 1175-5326 5760636 AA3269D1-CA2F-4528-BC9D-3A4C75D05BD9 5. Leprocaulinus mammatus (Rehn, 1904: 44) [ Carausius ]. HT, ♀ : Obi Island, Moluccas ; Carausius mammatus Rehn , Type No. 5143; Carausius mammatus Rehn [ANSP]. rev. stat., n. comb. Comments: Examination of the HT clearly places this species in Leprocaulinus and proves it to be not a synonym of L. vipera bituber (Sharp, 1898) , a taxon described from New Britain . Instead, L. mammatus appears to be closely related to L. vipera vipera ( Kaup, 1871 ) and L. obiensis (Rehn, 1904) and is here re-established as a valid species. Characters that distinguish it from the latter have been presented by Rehn (1904: 46) and a proper distinction from the nominate form of L. vipera ( Kaup, 1871 ) , originally described from ♂♂ from Sulawesi , would need material of both sexes.The subspecies and numerous synonymies currently attributed to Kaup’s vipera are very doubtful and require critical evaluation. Distribution: Maluku Islands , Obi [ANSP].
