Eunatalis mastersii (MacLeay, 1873)

( Figures 31–32 , 56 E)

Natalis mastersii MacLeay, 1873: 269 .

Specimens examined: Lectotype (designated here): Natalis mastersi fab., Gaynda, K34049 , K 209225; TYPE (♂, AM).

Comment on the type specimen: As Macleay (1873: 269) made no reference to specimens in his description it cannot be assumed that the nominal species-group name, Natalis mastersii , is based on a single specimen. Despite being labelled 'holotype' (a recent, not original, label) the 'type' located in the Australian Museum, Sydney (AM) must be considered a syntype (ICZN 1999: Article 73.2) and is therefore available for lectotype designation (ICZN 1999: Article 74.1).

Diagnosis: The pronotum of E. mastersii is longer than wide, conspicuously sinuate and convergent towards apex. The tegmen is conspicuously narrower in the middle than basally and apically.

Length: (49 specimens measured) Total length: 12–23 mm.

Head: Black, with isolated pilosity; with dense punctation and fine wrinkles; epistomal suture distinct; interocular space about one eye width.

Thorax: Pronotal length to width ratio 1.15:1; pronotum dark brown to black, with isolated pilosity and dense punctation, conspicuously sinuate, wrinkled (but not deeply) laterally; convergent towards apex; longer than broad; grooves of sub-basal collar separated by a wide, distinct bar. Scutellum black, with isolated pilosity and punctation.

Elytra: Elytral length to width ratio 2.58:1; elytra dark brown to black, partly shining reddish in basal half, with isolated pilosity; elytral base less broad than pronotum, slightly wider behind the middle; diameter of punctations slightly broader than interstices, punctations of striae 1 to 4 conspicuously decreasing from the middle, diameter of striae 5 to 8 conspicuously decreasing just before apex; punctations of tenth stria distinct up to shortly behind middle; punctations of ninth stria vestigial; elytral punctation with three nodules; interstices 6 and 8 weakly ridged from shortly behind the middle; interstices with weak microsculpture.

Lower surface: Dark brown to black, with isolated pilosity and punctation; procoxal cavities closed posteriorly.

Legs: Dark brown, with isolated pilosity and fine punctation; pro- and mesotibiae conspicuously bent.

Abdomen: Tegmen in the middle conspicuously narrower than basally and apically; closed ventrally; spicular fork fused up to middle.

Distribution: Mainly in the southern parts of Australia.

Seasonal occurrence: Collected from August to April.
