description: Eunatalis titana (Thomson, 1860)
(Figures 51–52, 58 C)
Natalis titana Thomson, 1860: 56; Blackburn 1899: 29; Schenkling, 1903: t3, f3.
Specimens examined: Holotype: Titana, Thoms. Mus.Sci. II 60.56, Typus, Nov. Hollan.; ex Museo James Thomson; Type (MNHN).
Comment on the type specimen: In stating "Spec. unie. in mus. nostro", (i.e. one specimen in my collection) Thomson (1860: 56) indicated that the nominal species-group taxon, Natalis titana, was based a single specimen. The 'type' located in the Muséum National d’Histoire Naturelle, Paris (MNHN) is therefore considered the holotype, fixed by monotypy (ICZN 1999: Article 73.1.2).

Diagnosis: E. titana is a larger species. The pronotal disc is characterized by isolated fine punctation, the pronotum is coarsely wrinkled laterally and the procoxal cavities are mostly open. The phallus is triangular, with a rounded tip.
Length: (94 specimens measured) Total length: 24–46mm.
Head: Black, with isolated pilosity and weak punctation, with fine wrinkles; epistomal suture distinct; interocular space about one eye width (or smaller).
Thorax: Pronotal length to width ratio 1.00:1; pronotum black, with isolated pilosity and weak punctation, sides with strongly protruding wrinkles (some specimens also dorsally, behind the middle, strongly wrinkled); strongly convergent towards apex; longitudinal groove weak; grooves of sub-basal collar indistinct, fused. Scutellum dark brown to black, with weak punctation.
Elytra: Elytral length to width ratio 2.53:1; elytra dark brown to black, basal half darker than apical half (one specimen with a light transverse fascia in the middle), with isolated pilosity; elytra subparallel to broader behind middle, apex partly conspicuously bevelled to slightly emarginate; elytral punctation strongly oblong, in basal half as wide as interstices, decreasing behind the middle, punctations of tenth stria conspicuous behind middle; punctations of ninth stria vestigial; elytral punctation with two laterally conspicuously protruding nodules; interstices 2, 4 and 6 slightly ridged, the other interstices flattened, with distinct microsculpture.
Lower surface: Dark brown to black, with dense pilosity, mesoventrite with distinct transverse convexity; metaventrite with dense pilosity and wrinkles; posterior part of mesepisternum not depressed; procoxal cavities slightly opened posteriorly.
Legs: Black, especially tibiae and inner edges of femora with dense pilosity, with dense punctation and wrinkles; mesotibiae bent.
Abdomen: Aedeagus, spicular fork, pygidium and sixth ventrite relatively large and deeply emarginate triangularly; tegmen ventrally closed, dorsally only base closed; phallus triangular with rounded tip; spicular fork fused to one-third.
Distribution: Mainly in eastern part of Australia and South Australia.
Seasonal occurrence: Collected from November to April.
