Pterorthochaetes storeyi Ballerio 2013

Size: HL = 0.70 mm; HW = 1.44 mm; PL = 1.50 mm; PW = 2.40 mm; EL = 2.66 mm; EW = 2.29 mm. Overall morphology as in generic description. Black, shiny, setation yellowish, sternum, tarsi and antennae reddish-brown. Head: completely and uniformly covered by impressed coarse punctation, punctures transverse, comma shaped on disc, horseshoe-shaped (with opening towards internal side) at sides of disc and on frons. Anterior portion of clypeus with irregular transverse anastomosing lines. Interocular distance about 11 times the maximum width of dorsal ocular area. Pronotum: margins completely bordered, lateral margins with a row of erect thick yellowish simple setae, longer than their distance. Pronotal setation made of thick medium sized clavate yellowish setae. Punctation as follows: disc covered by impressed transverse comma shaped punctures, with posterior openings and having a small fine setigerous pore near inferior side, sides of disc with a few ocellate punctures and sides of pronotum with larger horseshoe-shaped punctures with opening directed laterad. Anterior angles having six longitudinal irregular lines. Distance between punctures subequal to their diameter. Scutellum: basally with two longitudinal irregular rows of horseshoe-shaped punctures, uniting towards apex. Elytra: humeral callus poorly pronounced, sutural stria occupying the medial and distal third. Elytral punctation as follows: mixed simple fine punctures and longitudinal comma-shaped punctures with opening laterad, becoming horseshoe-shaped at apical third and at sides of elytra. Each comma-shaped and horseshoe-shaped puncture bearing bearing a clavate yellowish seta. Apical third of elytra with a few ocellate punctures. Interpunctural distance on elytra being larger than the diameter of punctures. Aedeagus: basal piece about two times as long as parameres. Parameres slightly asymmetrical, internal sac with distally some irregular weak sclerotisations (Fig. 12B, Fig. 13G–I). Male genital segment: as in Fig. 11A. Bursal sclerites: strongly asymmetrical, as in Fig. 14A, E, F and subject to strong variability.

Known from the Queensland Wet Tropics (sensu Adam 1992), where it occurs in lowland rainforest areas. Adults were collected mainly with flight intercept traps or at light. The Pterorthochaetes simplex quoted by Grove (2000) are actually specimens of Pterorthochaeres storeyi sp. n.
