Monteitheolus fijiensis Howden & Storey, 2000: 182 . Type locality: Fiji, Vanua Levu, Mount Delaikoro.

Diagnosis. Hadrorhyparus fijiensis is distinguished by its length 2.6 mm and width 1.3 mm ( Figs. 10–12 ). Clypeal margin with weak fringe of setae; surface with deep peridiscal groove and pits ( Fig. 15 ). Pronotal lateral margin with deep emarginations, with two distinct lobes ( Fig. 13 ); submarginal costa lobe like, not reaching posterior angle. Elytron with dorsal intercostal surfaces medially smooth, glabrous and glossy, setae only near costae; submarginal costa distinct posteriorly, distinctly curving upward into small but distinct caudal bulb; trichome not visible in groove between discomedian costa and caudal bulb ( Fig. 14 ). Metaventrite short, distance between mesocoxa and metacoxa less than or equal to width (long axis) of metacoxal; median groove is a rounded depression. Metafemur with posterior margin sinuate, with strong posterior marginal face entire length. Metatibia enlarged, dorsal (posterior margin) sinuate, not lobed, appearing simply twisted ( Figs. 10–11 ).

Distribution. Fiji (Vanua Levu).

Material examined. Holotype female ( QMA, photo examined, Fig. 10–15 , gender based on mesotibia lacking apical tooth): “ FIJI: VANUA LEVU: / Mt Delaikoro / 21 July 1987 / G. Monteith // Q.M. Berlesate No. 785 / 16.35’S. 179.20’E. / Rainforest 700m / Sieved litter // [red paper] HOLOTYPE / [handwritten] Monteitheolus / fijiensis / Howden + Storey // [yellow paper] QM Reg. No. / T46169 // [handwritten] Illustrated / G. Thompson / March, 1997 // [lavender paper] Photographed / Specimen” ( Fig. 16 ).

Comments. Of the three species here considered be Hadrorhyparus , H. fijiensis is most similar to Termitodiellus in body shape, with a broad pronotum having large pronotal lateral marginal lobes, and with metatibia slightly enlarged and only twisted (not lobed).
