Angara dohrni ( Brunner von Wattenwyl, 1891) comb. nov.

( Figs 4, 5, 13E, F)

Xenica dohrni Brunner von Wattenwyl 1891: 40 . Holotype male, Brazil: Santa Catarina (MIZ, examined through photographs).

Amended diagnosis: This species can be distinguished readily from its closest related species, Angara albofasciata and Angara nigrocercata , by having the pronotum not saddle-shaped, and with colours and morphology not resembling mosses. From the remaining species of Clade B, it can be differentiated by having the costal area entirely black; legs with brindle patterns, and apex of femur III black. From Angara nunoi and Angara flavolineata it can be distinguished readily by the posterior area of the pronotum wider than the anterior area; and male tegmina not covering the second abdominal tergite. It differs from Angara superba by the lateral carinae of the pronotum not crenellated and not yellow, first abdominal tergite of same colour as general body colour, and male cerci straight.

Complementary description: Overall aspect ( Figs 4A, 5A): medium to large-sized katydids, general colour green, with a lateral coloured strip from head to abdominal tip. Head ( Figs 4B, C, 5B– D): frons and gena smooth, blackish; fastigium of frons triangular, a little higher than wide, ocelli absent. Clypeus blackish proximally, whitish at apex. Labrum white, but apex greenish; maxillary and mandibular palps greenish. Scape as long as 0.5× pedicel; inner and posterior margin of scape and pedicel yellowish, lateral and anterior margin blackish; flagellum ≥ 4× longer than body, first two flagellomeres blackish laterally, brownish medially, with some black rings at every 5 articles, after its half with some white rings too. Fastigium of vertex with a negligible elevation, one lateral ocellus near half of fastigium of vertex. Thorax ( Figs 4B–E, 5C– F): pronotal disc ( Figs 4B, 5C) glabrous, green with small black punctuations; anterior margin slightly concave; posterior margin black and distinctly elevated. Lateral carinae ( Figs 4B, C, 5C, D) bearing a sulcus near half region, which extends to lateral lobes, a tricolour band throughout its extent, with a crimson–white––crimson pattern but slightly yellow on inferior margin of posterior region. Lateral lobes ( Figs 4C, 5D) long and slender, twice as long as wide, anterior and inferior margin straight, posterior margin widely diagonalized and slightly curved, inferior region black, middle region green. Tegmina ( Figs 4D, 5E) truncated, stridulatory vein light yellow, costal margin whitish, area between R and M entirely black, medial area blackish to greenish at apex, which is pointed. Epimeron II 2× wider than episternum II; epimeron III 1.5× wider than episternum III; episternum II and III and epimeron II and III, blackish, but greenish near coxa. Legs ( Figs 4A, 5A): all coxae with a blackish spot; all legs brownish, covered with black and testaceous stains, but whitish on superior edge; tibiae black on ventral margin at apex; three first tarsomeres black on ventral margin and brown dorsally, last tarsomere brownish; femur III 6.5× longer than pronotum. Abdomen ( Figs 4A, E, F, 6A, F, G): tergites with several crimson granulations; traversed by a tricolour band (seen only laterally), reddish–white–crimson from top to bottom. Tergite X ( Figs 4E, 5F) with a deep depression on medial region. Subgenital plate ( Figs 4F, 5G) trapezoidal, 2× longer than wide; styliform processes longer than wide; median keel absent. Cerci ( Figs 4E, F, 5F, G) slightly curved, long and slender, thickness decreasing gradually towards the apical curvature to the dorsal region, with a black apical tooth at apex.

Female, first description ( Fig. 10B): Larger than males. One light yellow strip from eye towards the pronotum. Anterior margin of pronotal disc straight. Lateral carinae well defined; bicolour, white on top and reddish on bottom. Tegmina squared, greenish, veins not evident. Abdomen plain brownish coloured, with overall coloration marks as in males. Ovipositor 3.5× longer than pronotal disc, slightly curved up at base, and acuminate; serrulations beginning on the distal sixth of dorsal valves and distal fifth of ventral valves.

Remarks: As previously mentioned, this species has been recorded in Argentina and Uruguay ( Braun 2021, Greco-Spíngola and Braun 2022). The type locality of Angara dohrni is located> 1000 km from these southern locations. Furthermore, these authors observed several key morphological differences between the specimens from Argentina and Uruguay and the holotype from Santa Catarina, particularly in the shape of the male tegmina and terminalia. The holotype of Angara dohrni features trapezoidal wings extending beyond half of the first abdominal tergite, in addition to thin cerci, nearly straight with a curved apex, longer than subgenital plate. In contrast, the specimens from Argentina and Uruguay have rounded tegmina shorter than half of the first abdominal tergite, and thicker and uniformly curved cerci, shorter than the subgenital plate.
