Lambkin, Kevin J., 2015, Revision of the Dysmorphoptilidae with emarginate tegmina (Hemiptera: Auchenorryncha: Cicadomorpha: Prosboloidea) of the Queensland Triassic, Zootaxa 3936 (3), pp. 357-374 : 365

Carsburgia knezouri sp. nov.

(Figs 7,11,12)

Material. Holotype left tegmen QM F57795 , Dinmore, collected by Allan Carsburg. Three paratype tegmina, all Dinmore: ACC I.118; RKC: QM F57796 +, QM F57797 +.

Description. Tegmen 5.4–6.5 mm long (holotype 5.4), 2.4–2.7 mm wide (holotype 2.4), length/width 2.3–2.7; hind margin of clavus with 3 irregularly spaced very small swellings ( Fig. 7 ); R with 1 or 2 costal veinlets; RA stem costal veinlet in holotype with a marginal fork; coloration as preserved comprising a pattern of dark and light areas as indicated in Fig. 11 , with a large basal spot between R and the claval suture, a spot at the apex of CuA, and two spots on RP.

Notes. There is some variation in the length of the RA1 stem, the separation of RA from RP and of RP from M, and the depth and separation of the branches of M and CuA (compare Figs 7 and 11 ). The species is named in honour of Robert Knezour who collected two of the four specimens known.
