Calleida terminata

Casale, Achille & Shi, Hongliang, 2018, Revision of the Oriental species of Calleida Latreille (sensu lato). Part 1: Introduction, groups of species, and species of six species groups (Coleoptera: Carabidae: Lebiini), Zootaxa 4442 (1) : 23

5. Calleida terminata species group

Diagnostic characters: With the character states of Calleida (in the widest sense, see above), restricted or amplified as follows: medium sized species (L: 8.5–11.0 mm). Pronotum and ventral side metallic green, or brown with marked metallic reflection, vertex with reddish patch; elytra metallic green or cupreous, with golden cupreous or purple hue at shoulders and/or near apex. Elytral outer apical angles markedly widened, forming distinctly sharp, acute angles. Abdominal sternum VII in male markedly notched at middle, with one seta on each side in males, two setae in females. Median lobe of aedeagus in lateral aspect with a distinct, very prominent ventral lobe.

Taxonomic note: Three species are attributed to this group, distributed in the Malay Peninsula, Sumatra, Borneo and southern Vietnam ( map 4 ). Species of this group are rare in collections, known so far from a few specimens from SE Asia.

The monophyly of this species group seems to be clear, for the following synapomorphic characters: elytral outer apical angles sharp, acute; male abdominal sternum VII markedly notched; median lobe of aedeagus with a distinct lobe on the ventral side.
