Euplectrus insularis (Howard)

Pachyscapha insularis Howard, 1897: 159. Lectotype ♂ (BMNH), examined.

Euplectrus insularis (Howard), Peck (1951: 453).

Material.

Type material: ♂ lectotype of Pachyscapha insularis (BMNH).

Diagnosis.

Very similar to the male of Euplectrus alvarowillei , i.e. with a black and strongly swollen scape (Fig. 59), pedicel and flagellomeres 1-2 yellowish-white and flagellomere 3 dark brown. Differs in having lower face medially reddish-brown (black in Euplectrus alvarowillei ); petiole transverse (0.8 × as long as wide) (1.0 × as long as wide in Euplectrus alvarowillei ); hind legs with coxae and femora yellowish-brown (darker in Euplectrus alvarowillei ).

Description.

Male. Length of body 1.6 mm. Antenna with scape black, strongly swollen, not possible to measure as both scapes have collapsed; pedicel and flagellomeres 1-2 yellowish-white, flagellomere 3 black with peduncle yellowish-white (flagellomeres 4-6 missing). Mandibles and palpi yellowish-brown. Head black and shiny, lower face medially reddish-brown. Vertex smooth and shiny. Occipital margin rounded.

Mesosoma black and shiny. Mesoscutum with sidelobes with several setae. Scutellum convex; 1.1 × as long as wide; with very weak reticulation, posterior and lateral margins smooth. Dorsellum along anterior margin with a very narrow groove. Propodeum smooth and shiny; anteromedially with a triangular cup; propodeal callus with seven setae. Legs yellowish-brown.

Gaster with anterior ½ yellowish-white with lateral margins dark brown, posterior ½ dark brown.

Ratios. HE/MS/WM = 1.4/1.3/1.0; POL/OOL/POO = 1.7/1.0/nm; OOL/DO = nm; WE/WF/WH/HH = 1.0/2.8/4.6/3.0; WH/WT = 1.2; PM/ST = nm; TS1/TS2/LT/LT1/LT2/LT3/LT4 = 4.0/2.0/7.2/2.6/1.4/1.0/1.8; LP/WP = 0.8; MM/LG = 1.4.

Hosts and biology.

Unknown.

Distribution.

The West Indies (Grenada) ( Howard 1897).

Remarks.

Bouček (1977) synonymized Euplectrus insularis with Euplectrus furnius . Euplectrus insularis is known only from males and Euplectrus furnius only from females. The biology is not known for either species. Until the host is known for either and the sexes can be associated it is best to keep these two species separate.
