Description

Females

Size: Body length 4.72 mm; intertegular span 0.97–1.07 mm; head width 1.16 mm.

Relative head measurements: HW 50; HL 40.4; UID 28.4; LID 30.8; WOC 8.5; OOD 6.5; IAD 14.1; SL 13; FL 254.3.

Structure: Face slightly wider than long; antennae low on face, located approximately two-thirds from the vertex (Fig. 1a); scape reaching just below the bottom of the facial fovea, approximately one-third from the vertex; pedicel longer and wider than any flagellomere; mandibles simple; eye inner margins convergent both below and above; supraclypeus raised and defined by suture; clypeus only weakly transversely convex; black facial fovea extending one third down eye, and converging mesad at the vertex to nearly meet the lateral ocelli; basitibial plates well-defined, dark (Fig. 1c).

Colouration: Eyes in live specimens blue; head yellow with black border separating the clypeus from supraclypeus and paraocular area; scape yellow, flagellum honey-brown; mandibles pale yellow and darkening at the tip (Fig. 1a); scutum bright yellow with honey-gold markings along the scutum-scutellum border and extending laterally up to the level of the pronotal lobes, parapsidal lines black (Fig. 1e); scutellum and axillae bright yellow, metanotum yellow bordered by black, propodeum black with yellow ellipse dorsally (Fig. 1e); sides of the thorax, legs, and tegula bright yellow (Fig. 1c); sternites cream, tergites yellow with thick bands dark brown on anterior of tergite, with lighter dark brown bands on the posterior of the tergite (Fig. 1e).

Sculpture: Body and head largely impunctate, with small, sparse punctures on anterior scutum and at base of hairs around vertex and on legs (Fig. 1a, c, e); horizontal part of propodeum longer than vertical part, propodeal triangle unsculpured and without a carina, but demarcated by being black rather than yellow (Fig. 1e).

Pubescence: Sparse, simple, relatively long hairs along bottom of the clypeus, genal region, forecoxa (Fig.1a), hind metatarsi, and the lateral and ventral region of the last tergite (Fig. 1c, e); shorter, sparse hairs along other parts of the legs, head, sides of the thorax, and anterior scutum (Fig. 1a, c, e).

Males

Size: Body length 4.00 mm; intertegular span 1.20 mm; head width 1.40 mm.

Relative head measurements: HW 50; HL 30.0; UID 17.0; LID 25.5; WOC 11.5; OOD 3.0; IAD 11.0; SL 11.0; FL 19.1.

Structure: Face wider than long, and concaved (Fig. 1b); antennae low on face, located approximately two-thirds from the vertex; eyes large and bulbous, converging above and below, slightly more above, the orbits arches outwards; scape reaches just below the bottom of the facial fovea, approximately one-third from the vertex; mandibles simple; clypeus only weakly transversely convex.

Colouration: Eyes in life black; head black-brown; scape dark brown at base, changing to yellow near pedicel; basal flagellomeres yellow; distal flagellomeres brown; mandibles pale yellow and darkening at the tip (Fig. 1b); scutum black, with yellow pronotal collar, pronotum and pronotal lobes; yellow markings from pronotum extending just outside of the notauli to adjacent with start of tegulae, concave in the middle (Fig. 1f); tegulae, mesepisternum, axillae and scutellum yellow (Fig. 1d); wing veins yellow; legs yellow; abdomen yellow (Fig. 1d), in some specimens darkening on posterior tergites and sternites.

Sculpture: Body and head largely impunctate, with small, sparse punctures on anterior scutum; larger punctures on legs; propodeal triangle unsculpured and without a carina.

Pubescence: Sparse, simple, short hairs dorsally on thorax and ventrally on abdomen, on clypeus, and medially on frons (Fig. 1b,d,f); propodeum bare; relatively longer, denser hairs along bottom of the clypeus, genal region, forecoxa, hind metatarsi, and along sides of propodeum and pronotum (Fig. 1b, d, f). Shorter, sparse hairs along other parts of the legs, head, sides of the thorax, and anterior scutum (Fig. 1b, d, f).
