Diagnosis. This species can be distinguished from the other species of the major species-group by the following combination of characters: body length 2.4–2.6 mm; eye one-half length of temple; ventral temple of male head with depressed and projecting temporal lobe and surface flattened; shape of antennomeres and genitalia unique to species; only known from Three Kings Islands.
