Eunatalis foveata Gerstmeier & Seitner 2013 , n. sp.

( Figures 9 , 19–20 , 55 E)

Specimens examined: Holotype: Qld: 26.24Sx 150.817E, Barakula SF, site 8, 424m, 1–15 Dec 2009, Malaise, Monteith & Turco 19187 (QM).

Paratypes: Yurraman, A.R.B., 11.47; O-166569, 4 ex. (QDPC). N. Galles, du Sud, Richmond River, 2 ex. (MNHN/RGCM). Milmerran, Q., MacQueen (ANIC). May. 13; Nov. Holl., Queensld. (MNHN). N.S. Wales (MNHN). Queensland 85.44 (BMNH). Swans Rd., Bruxner Pk, Flora RES., N.E. NSW, 30°14'S 150°8'E, 14 Nov 1983, ABRS, AM/AM. RF. (QM).

Diagnosis: Besides E. titana , this is the only species with only two lateral nodules in elytral punctation. Other than its larger size, E. titana differs from E. foveata n. sp. by the distinct transverse convexity of the mesoventrite.

Length: (15 specimens measured) Total length: 19–26 mm.

Head: Black, with isolated pilosity; spaciously covered with small and large punctures, with extremely fine microsculpture; epistomal suture distinct; interocular space about one eye width.

Thorax: Pronotal length to width ratio 1.08:1; pronotum black, with isolated pilosity, impunctate, sides of pronotum strongly and deeply wrinkled; grooves of sub-basal collar distinct, fused. Scutellum dark brown to black, with weak punctation.

Elytra: Elytral length to width ratio 2.33:1; elytra dark brown to black, with isolated pilosity; elytral base as wide as pronotum, broader behind the middle; elytral punctation not reaching apex; punctations in basal half as wide as interstices, abruptely smaller behind middle and decreasing, punctations of striae 7 and 8 partly decreasing just before apex, punctations of tenth striae distinct almost up to middle; punctations of ninth striae vestigial; elytral punctation with two conspicuously protruding lateral nodules (without basal nodules); interstice 4 weakly ridged just behind base, interstices 6 and 8 weakly ridged behind middle, interstices with extremely fine microsculpture.

Lower surface: Dark brown to black, with isolated pilosity; procoxal cavities distinctly closed behind; metaventrite with weak punctation and wrinkles.

Legs: Black, with dense pilosity, especially at inner edge; with dense punctation and fine wrinkles; mesotibiae bent.

Abdomen: Tegmen closed ventrally and conspicuously dilated; spicular fork fused to one-third.

Distribution: In the south-eastern part of Queensland and the most northern part of New South Wales.

Seasonal occurrence: Collected in May, November and December.

Etymology: The specific epithet, foveata , a Latin adjective refers to the strong wrinkles at pronotal sides.
