Gerstmeier, Roland & Seitner, Martin, 2013, Revision of the checkered beetle genus Eunatalis Schenkling, 1909 (Coleoptera: Cleridae: Clerinae), Zootaxa 3698 (1), pp. 1-77 : 32-36

Eunatalis lugubris (Blackburn, 1890)

( Figures 29–30 , 56 D)

Natalis lugubris Blackburn, 1890: 123 ; Blackburn 1899: 29, 31.

Eunatalis blackburni (Waterhouse, 1894) : 286; Blackburn 1899: 29 n. syn.

Specimens examined: Natalis lugubris : Holotype: Type, Australia, Blackburn Coll., B.M. 1910-236; Natalis lugubris Blackb. (BMNH).

Natalis blackburni : Lectotype (designated here): Swan River, 75.12, Natalis Blackburni , (Type) Waterh., (TYPE) (♂, BMNH).

Comment on the type specimens: In stating "the example before me" in the original description, Blackburn (1890: 124) implied that the nominal species-group taxon, Natalis lugubris , 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). Waterhouse (1894), on the other hand, made no reference to specimens in his description of Natalis blackburni , so the 'type' specimen located in the Natural History Museum, London (BMNH) must therefore be considered a syntype (ICZN 1999: Article 73.2) and available for lectotype designation (ICZN 1999: Article 74.1).

Diagnosis: The pronotum of E. lugubris is as long as wide, not conspicuously sinuate and only slightly wrinkled laterally; the apex is characterized by an oblique fovea at each side. The tegmen is, in comparison to phallus, very short and the phallic tip is slightly Z-shaped. The spicular fork is fused to four-fifths its length.

Length: (109 specimens measured) Total length: 18–33 mm.

Head: Black, with isolated pilosity; with dense, small punctation and isolated large punctures; epistomal suture distinct; interocular space about one eye width or only slightly more.

Thorax: Pronotal length to width ratio 1.0:1; pronotum dark brown to black, with isolated pilosity and punctation, wrinkled laterally; slightly convergent towards apex; apex with an oblique fovea at each side; grooves of sub-basal collar fused or separated. Scutellum dark brown to black, with weak punctation.

Elytra: Elytral length to width ratio 2.42:1; elytra dark brown to black, with isolated pilosity; base of elytra slightly broader than pronotum, subparallel or broader behind the middle; elytral punctation oblong in basal half, diameter of punctations as wide as interstices, abruptely decreasing behind the middle, towards apex almost becoming extinct; punctations of tenth stria distinct up to middle; punctations of ninth stria vestigial; elytral punctation with three nodules; interstices 2 and 4 ridged shortly behind base, interstices 6 and 8 weakly ridged behind the middle, interstices with conspicuous microsculpture.

Lower surface: Dark brown to black, with dense pilosity; metaventrite with dense punctation, weakly wrinkled; abdominal ventrites 2 and 3 with dense, light pilosity in the middle; procoxal cavities slightly opened to closed posteriorly.

Legs: Black, with dense pilosity and with dense punctation, with fine wrinkles; mesotibiae conspicuously bent.

Abdomen: Tegmen slightly opened ventrally, tegmen in comparison to phallus very short; phallic tip slightly bent Z-shaped, open; spicular fork fused to four-fifth.

Distribution: Mainly in Queensland, with further single locations in Western Australia, Northern territory, South Australia, New South Wales and Tasmania.

Seasonal occurrence: Collected in November and December.

Remarks: E. lugubris shows no morphological differences to E. blackburni and therefore E. blackburni was synonymized with E. lugubris . There is a hook-like structure at the ventral sides of the tegmen of E. blackburni , but this seems to be in the shape of variation.
