(Figs. 92–97)

Type material. Holotype: ♂, 33.25S 151.00E NSW The Lodge, Kosc. NP, 1800m 30 Dec. 1989 C.Reid, Phebalium ovatifolium ( ANIC). Paratypes: 1♂, same data as holotype. VIC: 1♂, VIC, Prettey Valley unter Mt. McKay, 7.1.1973, P.Zwick (genitalia on glass slide, PZ). 2♂, VIC, 4 K SE Falls Creek, 8/1/06 on Prostanthera flws, CHS.Watts ( SAMA).

Habitus. BL 2.4 mm, BL/BW 2.0. Flat, very slender, elytra parallel-sided. Uniformly dark brown, only legs a bit lighter. Flagellar segments twice as long as wide, slightly conical.

Male. Ventrocaudal edges of T9 forming sclerotized plump cones. Plate soft, caudally narrowed, truncate, edge irregularly serrate in middle, smooth on sides. S9 an elongate medially gently constricted plate with several setae next to the base of a long sclerotized flat spine with narrow base and acute tip.

Penis slender, pala almost parallel, longer than the slightly narrower caudal half which is tongue-shaped. It has a porous appearance, its sides are armed with distinct tooth-shaped asperities. The narrow tip of trigonium projects beneath the claw-like centema, resulting in a curious double tip.

The spine-like parameres fork out of a squarish base. Each paramere is flanged, appearing much wider in side view than in dorso-ventral view.

Female. Unknown.

Etymology. From the Latin stylatus —provided with a style.
