Description.

Male. Fore wing length 6.7-7.9 mm in ♂. Antenna with 33 (1 specimen)-36 (2 specimens) flagellomeres; all flagellomeres longer than wide and about equal width; antennal flagellum 1.2 × length of fore wing (Fig. 1 ); scape 2.3 × pedicel; distance between eyes ventrally c.0.8 × distance dorsally (Fig. 3a ); mandible more weakly twisted than in H. ashmolei sp. n., upper tooth 2.0 × lower tooth. Head and mesosoma covered in closely spaced, silvery setae, but sparser than in H. ashmolei sp. n. (Fig. 4a ); metasoma, beyond first tergite, covered in slightly sparser setae; notauli strongly impressed and narrow medially but faint on anterior slope and posteriorly disappearing in rugosity (Fig. 4a ). Head rugose, matt, pronotum rugose-punctate laterally, dorsally punctate, mesoscutum punctate, rugose posteriorly, mesopleuron punctate, transversely striate dorsally, mesosoma with shiny interspaces between obvious punctures. Hind trochanter dorsally 3.0 × as long as trochantellus, ventrally 1.0 ×; hind tarsal claws abruptly curved, fully pectinate (Fig. 5a ). First sternite without convexity sub-basally. Fore wing (Fig. 9a ) with cu-a slightly distal to Rs&M; hind wing with 9-10 hamuli on vein R 1; distal abscissa of Cu 1 with distal section reaching wing membrane, proximally distant from cu-a + basal section of Cu 1 (nervellus). Petiolar index 2.68; fore wing indices: CI 0.82; BI 1.09; DBI 0.49; ICI 1.23; MI 1.60; hind wing index: RI 1.25.

Colour. Red, paler than in H. ashmolei sp. n.; face, inner orbits, underside of scape bright yellow; frons and antennal flagellum black; mesosoma red with black on middle of median lobes of mesoscutum, mesoscutum posteriorly, mesopleuron dorsally, ventrally, mesosternum, propodeum dorsally, metasternum, upper division of metapleuron, postscutellum. Scutellum (mesoscutellum) black anteriorly, medially, ivory or yellow posteriorly and laterally. Following parts ivory: palps, pronotum dorso-posteriorly, ventro-posteriorly, propleural lobe, subalar prominence, fore and mid coxae and trochanters, fore trochantellus, mid trochantellus ventrally, hind trochanter and trochantellus ventrally. Hind coxa apically, dorsally, trochanter and trochantellus, femur basally, tibia and tarsus dark brown/black. First and second metasomal tergites black, remainder of metasoma and legs red.

Female: unknown.
