description: Eunatalis debilis (Blackburn, 1900)
(Figures 13–14, 55 B)
Natalis debilis Blackburn, 1900: 120.
Specimens examined: Holotype: Natalis debilis, Blackb.; Australia, Blackburn Coll. B.M. 1910 – 236.; 6725 T, Lyndhurst. (TYPE) (BMNH).
Comment on the type specimen: In stating "the specimen before me", Blackburn (1900: 121) implied that the nominal species-group taxon, Natalis debilis, was based on a single specimen. The 'type' located in the Natural History Museum, London (BMNH) is therefore considered the holotype, fixed by monotypy (ICZN 1999: Article 73.1.2).

Diagnosis: E. debilis is clearly recognizable by the extended pronotum and elytra, similar those of E. porcata and E. schopfi n. sp. E. debilis differs from all other species by the strongly punctate posterior part of the mesepisternum.
Length: (73 specimens measured) Total length: 14–17 mm.
Head: Black, with isolated pilosity; with dense punctation; epistomal suture inconspicuous; interocular space more than 1.5 eye width.
Thorax: Pronotal length to width ratio 1.17:1; pronotum black, dorsally and laterally with dense punctation; conspicuously longer than wide, more or less sinuate behind the base, wrinkles weak; grooves of sub-basal collar conspicuously separated by a wide, distinct bar. Scutellum dark brown to black.
Elytra: Elytral length to width ratio 3.06:1; elytra dark brown to black, in part with a transverse reddish fascia; elytral base as wide as or wider than pronotum, lateral margins subparallel; diameter of punctations as wide as interstices, punctation of equal diameter in basal and apical half; punctations of tenth stria conspicuous almost towards apex; elytral punctation with three nodules; interstice 4, 5 and 6 weakly ridged, interstices with conspicuous microsculpture.
Lower surface: Dark brown to black, with dense pilosity; procoxal cavities almost closed; posterior part of mesepisternum punctate; metaventrite with dense punctation and weak wrinkles.
Legs: Black, with isolated pilosity, with dense punctation and fine wrinkles; mesotibiae bent.
Abdomen: Tegmen opened ventrally, phallobasic apodeme terminating straight; spicular fork fused to twothird, dilated triangularly.
Distribution: Australia, mainly northern and south-eastern parts. Seasonal occurrence: Collected from July to April.
