Brevialavenosa temperata ( Walker, 1858b) new combination

Cicada temperata Walker, 1858b: 24 (Ega).

Cicada blandula Walker, 1858b: 24 (Ega).

REMARKS. Abroma temperata ( Fig. 3 , type specimen BMNH, specimen NHMUK010392118) and its junior synonym Cicada blandula ( Fig. 4 , type specimen BMNH, specimen NHMUK010392122) possess partially fused fore wing cubitus posterior and anal vein 1, division of fore wing vein cubitus anterior 1 with the proximal portion shorter than the distal portion, hindwing cubital cell 1 width twice the width of distal cubital cell 2, hindwing radius posterior and median veins fused at their bases, partially visible dorsal metanotum, male opercula not strongly S-shaped and lacking a deeply concave lateral margin, lack of timbal covers, undeveloped pygofer distal shoulder, pygofer upper lobe is present, and claspers that restrain the aedeagus that place the species in the Cicadettinae ( Marshall et al. 2018; Simon et al. 2019; Sanborn et al. 2020a). This combination of characters eliminates all remaining subfamilies as an option for the placement of the species.

In addition, Abroma temperata can be classified in the Taphurini Distant, 1905a based on the lack of timbal covers, the small opercula that curve towards the midline but remain well separated medially and do not cover the tympanal cavity completely, the undeveloped pygofer distal shoulder, the small upper pygofer lobes, the large, the lack of an uncus, the lateral lobes on the anal tube, and the presence of claspers. Within the Taphurini, the species is similar to species of Brevisalavenosa and Malloryalna Sanborn, 2016b . Comparing the species to the known species of these genera, the shape of the medial cell, ulnar cell 2 being about three quarters the length of ulnar cell 1 instead of being about the same length, the radial and radiomedial crossveins not being parallel, the pattern of infuscation on the distal fore wing and radial and radiomedial crossveins, the thickness of the costal margin, the curve in the hindwing margin at cubital cell 1, the angle of the timbals to the long body axis, the laterally lobed anal tube, and the tubular aedeagus suggest the species belongs to Brevialavenosa rather than Malloryalna . As a result, Abroma temperata ( Walker, 1858b) is reassigned to the genus Brevialavenosa Sanborn, 2021b to become Brevialavenosa temperata ( Walker, 1858b) n. comb. The transfer of both Brazilian species previously assigned to Abroma means there are no members of Lamotialnini remaining in Brazil or South America confirming the tribal distribution as outlined in Marshall et al. (2018).

DISTRIBUTION. The species is known only from Brazil ( Metcalf 1963c).
