Diagnosis
Guillermo is distinguished from all known Australian genera by its broadly separated pro- and mesocoxae, prosternum with broad prominent plate covering much of the head from below and peculiar long, geniculate maxillary palps.

Description
Length 1.2-1.6 mm. Body elongate-oval moderately convex; winged; dorsum uniformly hairy. head exposed. Dorsum brown sometimes with distinct darker markings on elytra. Head transverse with eyes somewhat coarsely facetted and distinctly emarginate, broadly separated. Antenna 11-segmented; slightly shorter than head capsule with scape normal; antennal club narrow 3-segmented. Maxillary palps geniculate, terminal palpomere weakly expanded apically. Pronotal disc evenly convex with complete lateral borders. Prothoracic hypomeron without fovea near anterior angles; prosternum very long in front of coxae, strongly prominent and arcuate medially forming broad plate; prosternal process very broad with carinae at basal half. Anterior margin of mesoventrite straight, mesoventrite distinctly broader than coxa. Elytral epipleuron narrow, incomplete at apex, not foveate. Protibia not angulated externally. Tarsi 4-segmented; claws simple. Tibial spurs absent. Abdominal postcoxal line recurved and complete. Male terminalia. Parameres and phallobase symmetrical; penis guide symmetrical. Parameres reduced and articulated with phallobase. Penis stout, consisting of single sclerite; basal capsule distinct and T-shaped. Apodeme of male sternum 9 very narrow and rod-like. Female terminalia. Coxities distinctly elongate, triangular; styli strongly reduced and hardly visible; infundibulum tube-like, enclosing the sperm duct; sperm duct simple, uniform in diameter. Spermatheca worm-like, without clear ramus or nodulus; spermathecal accessory gland absent.

Distribution and Biology
Endemic to Northern Queensland. Adults have been extracted from forest litter or collected in flight intercept traps in rainforest habitats.
