Description.

(Female) Head (Figs 7-8) 1.53-1.56 × wider than long, covered with long erect setae and short decumbent white setae; frons transversely rugose; surface around ocellar triangle rugose with rows of punctures behind anterior ocellus and outside of posterior ocelli, but lateral row indistinct among other sculptures; vertex reticulate rugose; eye margined posteriorly by foveate groove and single post-ocular orbital carina; gena smooth with irregular carinae under orbital carina; occipital carina dorso-laterally with a small depression; clypeus smooth.

Mesosoma (Fig. 9) entirely covered with short decumbent setae, but long erect setae also present on mesonotum; mesoscutum smooth; lateral carina present on anterior surface; dorsal surface not swollen; axilla and scutellum smooth; metanotum setose; propodeum (Fig. 14) with pair of median, submedian and lateral carinae; median propodeal region narrower centrally, with a few transverse carinae in holotype, carinae indistinct in a paratype; posterior margin dorsally producing; submedian region smooth excluding posterior areola, parallel-sided; lateral region with at most four transverse carinae but keels sometimes indistinct.

Fore wing (Fig. 7) bearing three transverse dark bands with clear spot around Rs+M; vein M 1.6-1.7 × basal part of RS; erect setae on C 2.0 × those on Sc+R, 1.2 × those on A.

Distribution.

Kalimantan Barat, Borneo.

Etymology.

The species name is dedicated to the collector of the types, Chris Reid, a coleopterist working at the Australian Museum, Sydney.

Remarks.

The specimens were collected as part of the Insects of Indonesia Project, a collaboration of the ROM with the MZB. This species is similar to Ettchellsia nigripes Mita & Shaw, sp. n. About identification of the two species, see the remarks of Ettchellsia nigripes .
