Eunatalis integra (Blackburn, 1899)

( Figures 23–24 , 56 A)

Natalis integra Blackburn, 1899: 29 , 30.

Specimens examined: Holotype: Natalis integra, Blackb. ; Australia, Blackburn Coll., B.M. 1910 – 236; 6393 Euc. T. (TYPE) (BMNH).

Comment on the type specimen: Blackburn (1899: 31) mentioned two specimens; one he referred to as "the type " plus a "second specimen taken near Adelaide", to which he did not allocate any type status. The type locality given after Blackburn's description is "S.Q. Australia (Eucla)". On one of the labels of the 'type' in the Natural Histoy Museum, London (BMNH) "6393 Euc. T." is written; 'Euc' referring to the locality Eucla and 'T' referring to it being the type. As Blackburn referred to the Eucla specimen as "the type " within the original description, that specimen can therefore be considered the holotype, fixed by original designation (ICZN 1999, Article 73.1.1).

Diagnosis: E. integra is characterized by its relatively large eyes (the interocular space being smaller than one eye width) and the isolated transverse wrinkles along the longitudinal pronotal groove. The phallic tip is triangular with a small hook-like structure and the tegmen is very short.

Length: (52 specimens measured) Total length: 10–14 mm.

Head: Black, with isolated pilosity; with dense punctation and wrinkles; epistomal suture distinct; eyes relatively large; interocular space smaller than one eye width.

Thorax: Pronotal length to width ratio 1.08:1; pronotum dark brown to black, with isolated pilosity, weak punctation and laterally with distinct wrinkles, isolated transverse wrinkles along the longitudinal groove; grooves of sub-basal collar separated by a wide bar. Scutellum dark brown to black.

Elytra: Elytral length to width ratio 2.76:1; elytra dark brown to black, with isolated pilosity; elytral base slightly wider than pronotum, broader behind middle, dorsally sinuate, apex rounded; punctations in basal half as wide as interstices, becoming smaller towards apex; elytral punctation with three nodules (laterally distinct, basally very weak); punctations of tenth stria distinct up to shortly behind middle; punctations of ninth stria vestigial, sometimes distinct; interstices very weakly ridged, with distinct microsculpture; humeri distinct.

Lower surface: Dark brown, with isolated pilosity; procoxal cavities opened posteriorly; prosternal process lighter; metaventrite with weak wrinkles; posterior part of mesepisternum smooth.

Legs: Black, with isolated pilosity and weak wrinkles; mesotibiae bent.

Abdomen: Tegmen closed ventrally; phallic tip triangular, with hook-like structure; spicular fork fused halfway; pygidial processes conspicuously extended.

Distribution: Australia, Tasmania.

Seasonal occurrence: Collected from August to May.
