Diagnosis. Males of H. insularis sp. n. are mostly similar to those of H. claviventris (also from the Lesser Antilles) but can be recognized by the larger yellow, integumental spot on the clypeus that covers its anterior half, and the presence of a circumocular carina (Fig. 1h); the base of the propodeum granulate medially (Fig. 1g) (striate in H. claviventris ), and the metafemur and metatibia dark brown (yellow in H. claviventris ). Females of H. insularis sp. n. resemble females of H. bimaculatu s in the overall coloration of the metasomal integument but differ from it by not having any spots or bands on the terga (Fig. 1c).

Description. Female. Total body length 4.35 mm; forewing length 3.43 mm. Head slightly wider than long. Scape longer than combined length of F1–F6; F10 as long as F9; F2 subequal in length to F1. Clypeus with upper margin above lower tangent of compound eyes, paraocular lobe, 160°. Scutum wider than long; metanotum 0.4× scutellar length. Mid tibial spur serrate, half length of basitarsus; inner hind tibial spur with four teeth (including apex); 1m-cu confluent with second submarginal crossvein; 2m-cu basad to 2rs-m by 3× vein width; first submarginal cell as long as combined lengths of second and third submarginal cells; second submarginal cell with anterior margin shorter than anterior margin of third submarginal cell; hamuli spaced 1-1-1-2. Basal area of propodeum as long as combined length of scutum and scutellum. Metasoma more or less flat and semi-petiolate.

Mandible with weak acetabular groove. Labrum flat without sulcus or central process. Clypeus, supraclypeal, and paraocular areas minutely but strongly granular, punctures present on lower third of clypeus, close together; remainder of face and vertex strongly granulate; gena and postgena imbricate. Scape imbricate, with
