Diagnosis.

This species can be distinguished from Porongurup clarkei sp. nov. by the smaller size of the male genitalia ( Fig. 2 View Figure 2 ), the subquadrate antennomere III ( Fig. 4A, B View Figure 4 ), and the length of abdominal segment VI is approximately twice as long as V. This species is also separated from Porongurup tenuis sp. nov. by the length of abdominal segment VI being twice as long as V ( Fig. 1 View Figure 1 ), and the parameres of the male genitalia approximately are twice as wide as those of the other species ( Fig. 2 View Figure 2 ).

Description.

Length 1.7-1.9 mm ( Fig. 1A, D View Figure 1 ). Head. Head in dorsal view with deep frontal sulcus and vertexal foveae ( Fig. 4G View Figure 4 ). Antennomeres II longer than wide, III subquadrate, smallest of the antennomeres, IV and V longer than wide, VI and VIII as long as wide, IX and X transverse ( Fig. 4A, B View Figure 4 ). Abdomen. Length of abdominal segment VI twice as long as V in both sexes ( Fig. 1A, D View Figure 1 ). Aedeagus. Median lobe of male genitalia elongated triangular, lacking articulated extension at tip of apex. Phallobase rounded in dorsal view. Parameres as wide as at middle of median lobe ( Fig. 2A View Figure 2 ).

Etymology.

This species name refers to the sub-apically angulate parameres of the male genitalia.

Distribution.

Western Australia ( Fig. 5 View Figure 5 , circles).

Habitat.

Specimens of this species were collected using flight intercept traps, or were taken by sifting leaf, bark, log, or fungus in Eucalyptus forests.
