DISTRIBUTION AND BIONOMICS: Corethrella lutea is known from Brunei and Sarawak , Malaysia from 30–200 m ( Fig. 15A ). Habitats include lowland peat swamps (including standing water and very slow moving streams) and steep terrain in mature mixed dipterocarp forest ( Figs. 1 A, D, E). They are relatively common in frog-call traps in Brunei ( Grafe et al . 2008 , as morphotype 2) and have been collected feeding on calling males of three species of frogs (Table 7). TAXONOMIC DISCUSSION: The seven females noted by Borkent (2008) in the taxonomic discussion of C. nippon , collected from a tributary of Sungai Belalong, Temburong district, Brunei , are paratypes of C. lutea here. Six females collected from the headquarters of Gunung Mulu National Park, Sarawak , Malaysia ( 113° 55'E , 4° 23'N ) on 14-XI-2009 with a frog-call trap differed from other C. lutea in having only a single sensilla coeloconicum on each of flagellomeres 10–12 and relatively shorter flagellomeres 2–3 (only one slide-mounted). For the present we consider these as variants of C. lutea . The females of C. lutea are very similar to those of C. nippon but the latter have relatively thicker midfemora. Although the male of C. lutea is unknown, and therefore we do not know if this species shares the only synapomorphy for the group (unequal male midclaws), we consider it a member of the drakensbergensis species group ( Fig. 19 ). It has synapomorphy 25 but lacks 26 and 27 (hence, an unresolved lineage along with C. nippon and C. harrisoni Freeman (Borkent, 2008)) .

DERIVATION OF SPECIFIC EPITHET: The name lutea (yellow) refers to the overall yellowish appearance of the females of this species.
