Variation. Mystacal macrosetae with 4 lateral dark brown macrosetae; orbital setae black; ocellar tubercle with 1 pair of setae; scape with ventral black setae mixed with other whitish setae; subvibrissal setae black; palpal setae dark brown to black; some dark brown occipital setae mixed with the whitish setae; postocular setae with inner macrosetae dark brown; scutellum with short, black discal setae; legs dark reddish; abdomen dark brown and grey pruinose; hypandrium with 5–6 black macrosetae at posterior margin laterally to mid-posterior projection; midposterior hypandrial projection with black setae mixed with white setae at posterior margin.
Etymology. platylobus , from Greek: platys: meaning broad, wide or flat; and lobos: elongate projection or protuberance, capsule or pod. The name makes an allusion to the rounded, laterally compressed lobe projecting at the ventral base of the second article of the stylus.
