The Bhutan Pine Aphid Pseudessigella brachychaeta Hille RisLambers (Hemiptera: Aphididae: Lachninae) From India Reveals the Hitherto UnknownOviparous Female and Dwarfish Male

摘要

Here we describethe presence of the monotypic and poorly known aphid genus Hille Ris Lambers (Hemiptera: Aphididae: Lachninae) in India. So far, the genushas only been known from Punjab, Pakistan. Representatives of Hille Ris Lambers were collected from A.B.Jacks. in the Yousmarg region of the state of Jammu and Kashmir in India. Hitherto unknownoviparous females and dwarfish males, the latter reported in Eulachnini for the first time,are described and illustrated. The male’s antennal sensilla and genitalic morphology areadditionally studied and presented using Scanning Electron Microscopy. Notes on thebiology, distribution, and previously overlooked generic features are given. We providemorphological identi cation keys to the genera of the tribe Eulachnini and to the speciesof aphid living on .
