Taxonomic Notes on the Hover Wasp Genus Eustenogaster (Vespidae, Stenogastrinae), With Description of Two New Species From Sumatra Island, Indonesia

Abstract

Wasps of the genus Eustenogaster van der Vecht, 1969, with 17 species currently recognized, are distributed from the Indian subcontinent in the west to the Philippines, Sulawesi Island and Java Island in the east. Two new species of hover wasp genus Eustenogaster (E. multifolia sp. nov., E. sumatraensis sp. nov.) are described from specimens collected in Sumatra Island. The female of E. vietnamensis occurring in Vietnam are described for the first time. The lectotypes of Paravespa eva Bell, 1936 and Ischnogaster ornatifrons Cameron, 1902 are designated. The new taxonomic status is proposed for Stenogaster eximioides Dover and Rao, 1922 as a good (=valid) species of Eustenogaster. The synonymy of Ischnogaster ornatifrons Cameron, 1902 with Eustenogaster micans (de Saussure, 1852) has been confirmed. A revised key to species and a taxonomic and distributional checklist of all the species of Eustenogaster are provided.

Herpetofauna diversity in Tengah Waterfall (Coban Tengah), Krajan, Pandensari village, Pujon district, Malang regency, Indonesia

“…Indonesia has 2000 species of reptiles out of a total of more than 7000 species of reptiles in the world and around 350 amphibians can be found in Indonesia out of a total of 4,950 amphibians in the world [4]. The Amphibia class is divided into 2 groups, namely Anura (338 species of frogs and toads) and Apoda or Gymnophiona (12 species of legless Amphibia) [5].…”

“…with a lack of further surveys. Previous data only showed 39 amphibian species (mostly dominated by the Anura amphibian species, and 3 Gymnophiona species) [5]. on the island of Java, most of the data came from the West Java region, especially the Gunung Gede Pangrango National Park and the Gunung Halimun-Salak National Park [12][13][14], and several areas in Central Java Province, especially in the Mount Slamet Region [15].…”
