description: Eunatalis semicostata (Blackburn, 1889)
(Figures 45–46, 57 F)
Natalis semicostata Blackburn, 1889: 1427; Blackburn 1899: 29, 31.
Euatalis alternicostata (Kuwert, 1893): 484; Blackburn 1899: 29, n. syn. Eunatalis lata (Waterhouse,1894): 287; Blackburn 1899: 29, n. syn.
Specimens examined: Natalis semicostata: Lectotype (designated here): Natalis semicostata, Blackb., Australia., Blackburn Coll., B.M. 1910-236., 2421 T.; Type (BMNH).
Natalis alternicostata: Lectotype (designated here): Natalis alternicostatus Kuw., New Holland,? TYPE; (TYPE Alternicostatus) (MNHM).
Natalis lata: Lectotype (designated here): Moreton Bay; Natalis latus, (Type) Waterh. (Type) (BMNH).
Comment on the type specimens: Natalis semicostata: In stating "the examples before me", Blackburn (1889: 1428) indicated that the nominal species-group taxon, Natalis debilis, was based on more than one specimen. As there is nothing in his paper indicating which specimen Blackburn considered the 'type', the specimen located in the Natural History Museum, London (BMNH) is therefore considered a syntype (ICZN 1999: Article 73.2) and available for lectotype designation (ICZN 1999: Article 74.1).
Natalis alternicostata: As Kuwert (1893) made no reference to specimens in his description it cannot be assumed that the nominal species-group name, Natalis alternicostata, was based on a single specimen. The 'type' specimen located in the Muséum National d’Histoire Naturelle, Paris (MNHN) must therefore be considered a syntype (ICZN 1999: Article 73.2) and available for lectotype designation (ICZN 1999: Article 74.1).
Natalis lata: As Waterhouse (1894) made no reference to specimens in his description it cannot be assumed that the nominal species-group name, Natalis lata, was based on a single specimen. 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: In combination, the narrow interocular space and the almost straight mesotibiae are the best characters for recognizing E. semicostata. The phallic tip is triangular and slightly emarginate; the spicular fork is only fused basally.
Length: (83 specimens measured) Total length: 16–25mm.
Head: Black, with isolated pilosity; with dense punctation and fine wrinkles; eyes strongly convex; interocular space about one eye width (or slightly more).
Thorax: Pronotal length to width ratio 1.10:1; pronotum light brown to dark brown, with more or less distinct pilosity; pronotum with distinct punctation, sides with conspicuously protruding wrinkles; grooves of sub-basal collar distinct, separated by a wide, flattened bar or almost fused. Scutellum dark brown, with weak punctation.
Elytra: Elytral length to width ratio 2.16:1; elytra light brown to dark brown, sometimes with a dark fascia in the middle; with isolated pilosity; elytral base slightly wider than pronotum, conspicuously broader behind middle, apex broadly rounded, lower lateral margin conspicuously protruding behind middle; diameter of punctations in basal half double as wide as interstices, first to fourth row of punctations abruptly decreasing behind middle, becoming extinct towards apex, fourth to eighth row of punctations only slightly decreasing behind middle; punctations of tenth stria distinct towards middle; punctations of ninth stria vestigial; elytral punctation with three nodules, basal nodule less distinct; interstices flattened in basal half, interstices 4, 6 and 8 conspicuously ridged shortly before middle, the others more or less flattened.
Lower surface: Light brown to dark brown, with dense pilosity, procoxal cavities opened posteriorly; mesoventrite weakly punctate, metaventrite slightly punctate and wrinkled, posterior part of mesepisternum impunctate; second and third abdominal ventrite with dense pilosity in the middle.
Legs: Dark brown, with isolated pilosity, fine punctation; mesotibiae almost straight.
Abdomen: Tegmen ventrally and laterally broadly closed; phallic tip triangular and slightly emarginate; spicular fork fused only basally.
Distribution: Mainly coastal regions and inlands of East and South Australia, isolated localities in Northern Territory and Western Australia.
Seasonal occurrence: Collected from October to March.
Remarks: The type specimens of E. alternicostata, E. lata and E. semicostata did not show any differences in aedeagus, pygidium and sixth abdominal ventrite, therefore the species E. alternicostata and E. lata were synonymized with E. semicostata. The detailed descriptions of Blackburn (1889, 1890) for E. semicostata agree with our description above, except the typical shape of the first antennal segment.
