A new species of leaf insect, Phyllium (Phyllium) letiranti Cumming and Teemsma, new species (Phasmida: Phylliidae), is described from a series of males, females, and eggs from Peleng Island, Indonesia. This new species is the first record of the family Phylliidae on the island and is here differentiated from congeners. Keys to males, females, and eggs of the Phyllium species of Sulawesi and Peleng islands are included within.
Four new species of Lobolibethra Hennemann & Conle, 2007 (Diapheromerinae: Diapheromerini: “Clonistria-group”) are described and illustrated. Lobolibethra carbonelli sp. nov. and L. pozuzoae sp. nov. from eastern Peru are described from both sexes and the eggs, L. tricarinata sp. nov. from southeast Ecuador is described from the female and male, and L. verruculosa sp. nov. from eastern Peru is described from the male. The previously unknown males of the Peruvian L. mainerii (Giglio-Tos, 1910) and L. mutica Hennemann & Conle, 2007 are described and illustrated. Dyme iconnicoffi Caudell, 1918 is shown to represent the previously unknown male of L. mainerii (Giglio-Tos, 1910) and is synonymised (syn. nov.). An updated key is presented for the eleven known species of Lobolibethra.
The genus Otraleus Günther, 1935 is recorded from the Philippines for the first time. Four new species, Otraleus bellemansae sp. nov., O. applai sp. nov., O. christianae sp. nov. and O. elizabethae sp. nov., are described from the highlands of Northwestern Luzon. The characters allowing separation from O. hypsimelathrus Günther, 1935 and O. labanrataensis Soew-Choen, 2016, are given. A new genus closely related to Otraleus, Capuyanus gen. nov., is described with a single species, C. magwilangi sp. nov., as type-species. An identification key and distribution maps are provided for all species.
The new genus Lobofemora gen. nov. is described from Vietnam to accommodate three new species: L. bachmaensis sp. nov. (Bach Ma National Park, central Vietnam), L. bidoupensis sp. nov. (Bidoup-Nui Ba National Park, central Vietnam) and L. scheirei sp. nov., the type species (Cat Tien National Park and Dong Nai Biosphere Reserve, south Vietnam). It is provisionally placed in the tribe Clitumnini Brunner von Wattenwyl, 1893. The genus is the only known Clitumnini which shows tegmina and sometimes alae in the males. Females show conspicuous foliaceous lobes on the median femora. Males and females of all species and the eggs of L. scheirei sp. nov. and L. bidoupensis sp. nov. are described and illustrated. An identification key to the species and a distribution map are provided. The definition of the tribe Clitumnini sensu Hennemann & Conle (2008) is slightly adapted to include the new genus and the tribal placement is discussed. The male of L. scheirei sp. nov. is able to stridulate by rubbing the outer margins of the tegmina against the subcostal and radial veins of the alae.
