🔓 • 2025 :: hanssoni • A New Genus (Hymenoptera: : Tetrastichinae) from : the first eulophid with a metasomal carapace

DOI: doi.org/10.3897/jhr.98.144864 🔓

Abstract :: Chelonastichus Ranjith & Quicke, gen. nov., is described based on a new species, C. hanssoni Ranjith & Quicke, sp. nov., from Thailand. Whereas most Eulophidae exhibit a delicate, collapsible body, the new genus, is the first known case within the family that possesses a coarsely-sculptured metasomal carapace formed by Gt5, with Gt2–4 short. The possible affinities of the new genus are discussed and it is tentatively placed in the Tetrastichinae.

Chelonastichus Ranjith & Quicke, gen. nov.
Chelonastichus hanssoni Ranjith & Quicke, sp. nov.

Etymology. The genus name derived from a combination of a generic name from the family , ‘Chelonus’ because of the first instance of carapace-like metasoma in the family Eulophidae and ‘astichus’ from the subfamily name Tetrastichinae where this genus is provisionally included.

Most people don’t realise the ecological value of solitary bees. This nice article explains why they are important to biodiversity and food security.

Also, it leans on some solitary bee research that we published, namely a study on solitary bee flight ranges available here https://doi.org/10.3897/jhr.77.51182

Solitary bees are a diverse group of wild bees that nest alone rather than in hives or colonies like honeybees or bumblebees
