Worldwide species of the genus Spathius Nees with reduced wings are reviewed. A new micropterous species, Spathius himalayicus Ranjith et Belokobylskij, sp. nov. from Northeast India is described and illustrated. A key to all known brachypterous, micropterous and apterous Spathius species is provided. Images of seven species not previously imaged, viz., S. apotanus Wilkinson, 1931, S. canariensis Hedqvist, 1976, S. critolaus Nixon, 1939, S. cursor Wilkinson, 1931, S. maderi Fahringer, 1930, S. pedestris Wesmael, 1838 and S. turneri Nixon, 1943, are provided.
Two new species of the subfamily Dorylinae Leach, 1815 namely Parasyscia ganeshaiahisp. nov. and Syscia indicasp. nov. are described and illustrated based on the worker caste. These species were collected in the Eaglenest Wildlife Sanctuary, Arunachal Pradesh, Northeast India. Keys to Parasyscia of India and Syscia of Asia are provided based on the worker caste.
Protanilla gengma Xu, 2012 is recorded for the first time from the Indian subcontinent. This rarely collected ant species was previously known only from Yunnan Province, China. Two workers of P. gengma were collected from the Lengteng Wildlife Sanctuary, Mizoram, Northeast India, using the Winkler extraction method. This find also represents the first record of the subfamily Leptanillinae from Northeast India and the third species of the genus Protanilla Taylor, 1990 from India. We present an updated distribution map for the genus and comment on morphological variation of the worker caste of P. gengma.
Two new species of the ant genus Myrmecina Curtis, 1829, M. bawai sp. nov. and M. reticulata sp. nov., are described and illustrated based on the worker caste from Mizoram, Northeast India. The genus is reported for the first time from Mizoram, the Indian state with the highest percentage of forest cover. A key to the Indian fauna of Myrmecina is also provided based on the worker caste.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
