This species belongs to Closterocerus s.str., but it is difficult to establish its species identity because the head, including the antennae, are missing. Especially the antennae are very important for the identification of Closterocerus species, but to a certain extent also the head, e.g. the sculpture on, and size of vertex, are used to separate species. Therefore it cannot be included in the key.

The holotype female ( Fig. 199 View Figs 195–199 ) lacks a carina along anterior margin of pronotum. Mesoscutum and mesoscutellum have quite strong reticulation; mesoscutum is metallic purple and mesoscutellum metallic purple with median part golden-green; midlobe of mesoscutum has short setae of an uncertain number. Legs: coxae difficult to see; fore and mid femora predominantly white, hind femur dark brown with apex white; tibiae white; tarsi white. Fore wing hyaline with parts below stigmal vein and along apical margin infuscate; speculum is closed. This combination of features does not match any of the included species and I therefore keep C. purpureus as a valid species of Closterocerus .

Hosts. Unknown.

Distribution. Grenada ( Howard 1897).

Material examined. Type material. Holotype ♀ of N. purpureus (B.M.Type Hym. No. 5.1299).
