Abstract

A second species of the rogadine braconid wasp genus, Batothecoides Watanabe, 1958 is described from Thailand, the genus having been known only from the type species for the past 66 years. The new species, Batothecoides sirindhornae Ranjith, Butcher & Quicke, sp. nov., is distinguished from the type species of the genus, B. yakushimensis (Watanabe, 1938), by morphology, color and DNA sequence data. The type species is redescribed based on images of the holotype. A molecular phylogeny of all members of the subtribe Spinariina for which barcode data are available is presented.

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.

Etymology. The genus name derived from a combination of a generic name from the family Braconidae, ‘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.
