The Oriental genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Purusha Distant, 1906 is reviewed and a key to the genera of Eurybrachini is given. Two new species, P. bellissima sp. nov. and P. vietnamica sp. nov. are described from Myanmar and North Vietnam, respectively. Purusha rubromaculata Distant, 1906 is proposed as a junior synonym of P. reversa (Hope, 1843). All species are illustrated, including all type specimens and the male genitalia for the first time. Distribution maps, identification key to species and biological data are provided. The sexual dimorphism in the genus is discussed. Five species are currently placed in Purusha.
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.
We revise the Southeast Asian Pholcus bicornutus group in which males are characterized by a unique pair of horns on their ocular area, each of which carries at its tip a brush of hairs. In two species, the two hair brushes are ‘glued’ or ‘waxed’ together by an unidentified substance into a very consistently curved and pointed single median tip. In the other five species known, the hairs are unglued. We present a first revision of ocular modifications in Pholcidae and identify twenty supposedly independent origins. Most cases are in Pholcinae, and all but one case are limited to the male, suggesting sexual selection as the main driving force in the evolution of ocular modifications in Pholcidae. Previously, the Pholcus bicornutus group consisted of four species limited to the Philippines. We describe four new species, including three species from the Philippines (P. olangapo Huber, sp. nov.; P. kawit Huber, sp. nov.; P. baguio Huber, sp. nov.) and the first representative from outside the Philippines (P. mulu Huber, sp. nov. from Sarawak, NE Borneo) and provide new records and SEM data for three previously described species.
Adesmus martinsi (Coleoptera, Cerambycidae, Lamiinae, Hemilophini), a new species from Bolivia, is described, illustrated, and included in a previous key. The new species displays gender dimorphism in the pubescent pattern and in anatomical structure. Thus, Adesmus becomes the second genus recorded in the Hemilophini to have visual chromatic dimorphism.
