Nothocyphon banksiae

n. sp.

Nothocyphon banksiae   , n. sp.

( Figs. 21−24 View FIGURES 17 – 24 )

Type material: 1 ♂ holotype: NSW New England NP Banksia Point   22 / 11 /06 CHS.Watts / 597 ( SAMA).

Habitus. Oval, stout, BL 2.6mm, BL/BW ~ 1.55. Light brown, shining. Centre of head, a narrow strip along front margin of elytra including humeri and scutellum yellowish brown. Sutural interval lighter than rest of elytra. The granular punctures on the head are very fine and dense, those on pronotum little larger. The normal punctures on the elytra again larger but still relatively fine, over 2 diameters apart. The pilosity is light brown to yellowish. Antenna short and stout, flagellar segments only about 1.5 times longer than wide at apex.

Male ( Figs. 21−24 View FIGURES 17 – 24 ). The base of S 9 is not visible, caudally S 9 is indistinctly bilobed, slightly scooped out, the apical setae are unusually small. In the centre rises a sharp caudally pointing hollow tooth. Penis with long anteriorly rounded pala that narrows gradually caudad. The transverse bridge in the distal third of penis supports a U-shaped trigonium. Each of its two lobes is caudally rounded and caudo-medially densely beset with a pelt of spines that are directed medio-caudad. The parameroids are narrow transparent unsclerotized fingers a little longer than the trigonium (left one in Fig. 24 View FIGURES 17 – 24 twisted, an artifact). The tegmen is a thread-like sclerite that widens continuously on the sides and supports the parameres. Each paramere is a slender strut with several spines, the subapical spine is largest.

Female. Unknown.

Note. The hollow spine on S 9 ( Fig. 19 View FIGURES 17 – 24 ) shows that N. banksiae   belongs in the N. lindensis   species group. The shape of the trigonium and parameres differ much from all other species. The only ♂ was taken together with N. auritus   n. sp.

Etymology. Named after the type locality which is itself named after the plant genus, Banksia   .
