Angara albofasciata Brunner von Wattenwyl, 1891

( Figs 2, 13A, B)

Angara albofasciata Brunner von Wattenwyl 1891: 38 . Holotype male, Brazil: Santa Catarina, Águas Mornas (‘Theresopolis’) (NHM, examined).

Amended diagnosis: Angara albofasciata can be distinguished from species of Angara of Clade A by the aforementioned characters; from species of Clade B it can be distinguished readily by the combination of: head larger than pronotum; anterior and posterior margins of pronotum elevated giving and saddle-like aspect; tegmina shorter than pronotum; larger tibial spines; and styliform processes of male subgenital plate much wider than large. From its closest species, Angara nigromarginata , it can be distinguished by the shorter tegmina, yellowish and thinner cerci, tibial spines shorter and fewer black spots on body.

Complementary description: Holotype male ( Fig. 2): Overall aspect ( Figs 2A, 13A, B): small-sized katydids, tibiae with several conspicuous spines. Head ( Fig. 2B, C): frons smooth; a medial black line from fastigium reaching clypeus, a lateral black line from lateral edges of fastigium towards clypeus but not reaching it, superior margin entirely black, covering half of frons; gena smoth, plain colour; fastigium of frons triangular, much higher than wide, ocelli present, yellowish. Clypeus, labrum, maxillary and mandibular palps whitish. Pedicel as long as 0.7× of scape; inner and posterior margins of scape and pedicel yellow, anterior and lateral margins brownish; flagellum ≥ 3× longer than body, brownish black with white rings. Fastigium of vertex elevated; entirely white; a lateral ocellus near half of fastigium of vertex; a medial whitish line from fastigium of vertex towards pronotum. Thorax ( Fig. 2B–D): pronotal disc ( Fig. 2B, C) saddle-shaped, anterior and posterior margins elevated; smaller than head; glabrous; anterior margin slightly concave, posterior margin concave; a thin whitish line on medial region; black spots on anterior and posterior margins. Lateral carinae ( Fig. 2B, C) bearing a sulcus before half region that extends diagonally to anterior region of lateral lobes, a whitish band throughout its extent. Lateral lobes ( Fig.2C) long, 1.3×longerthanhigh;anteriormarginsinuous; inferior margin straight; posterior margin straight; blackish brown with black and whitish punctuations. Tegmina ( Fig. 2D) truncated; stridulatory vein yellow; costal margin brownish; medial area blackish to yellowish at apex, which is pointed. Episternum II 1.5× wider than epimeron II; episternum III 1.2× wider than epimeron III; all epimera and episterna brownish with blackish and whitish stains. Legs ( Fig. 2A): coxa I entirely white; coxae II and III yellowish–brownish; all trochanter brownish. Midleg brownish, covered with testaceous stains. Abdomen ( Fig. 2A, E, F): tergites with several black punctations, denser on the anterior region; tergites VII–X with punctations only near medial region, dorsolateral region with no punctuation; pleura entirely white. Tergite X ( Fig. 2E) with a deep margination on medial region. Subgenital plate ( Fig. 2F) trapezoidal, longer than wide; styliform processes much wider than long; posterior margin slightly concave; median keel absent; shorter than cerci; entirely white, but black punctuations at base. Cerci ( Fig. 2E, F) straight; longer than subgenital plate; apex strongly curved to the medial region; thickness decreasing gradually towards apex, where it decreases abruptly, with a black apical tooth at apex; ventral edge black, dorsal edge brownish black.

Female: Unknown.

Measurements (in millimetres): Holotype male: BL, 10.2; TegL, 1.9; HW, 2.1; HH, 2.4; PrL, 1.5; PLL, 1.3; PrH, 1.1; SPL, 0.9; CL, 1.2. Additional examined male: BL, 10.3; TegL, 2.1; HW, 2.3; HH, 2.5; PrL, 1.6; PLL, 1.5; PrH, 1.2; FLiii, 16.8; TLiii, 22.4; SPL, 0.9; CL, 1.3.

Type material: Holotype male, labelled ‘Coll. Br. v. W. \ Theresopolis [handwritten] \ [Fruhstorfer]’ ‘det. Br.v.W. \ Ag. albofasciata [handwritten]’, ‘ Holotype [red label]’. Deposited at NHM.

Additional examined material: One male, ‘ Brasil, PR, São José dos \ Pinhais 22-27.III.2022 \ J. Henke’ ‘MFM095 ’.

Remarks: The holotype was examined directly by the first author during his stay at NHM in 2022. It is in relatively good condition, except for missing fore- and hindlegs and having broken antennae, but damaged when compared with the illustration in the original description, shown with all legs and antennae ( Brunner von Wattenwyl 1891: fig. 1, p. 197). The type locality of Angara albofasciata , indicated as ‘Theresopolis’ in the original description, is considered by the Orthoptera Species File as Teresópolis, Rio de Janeiro State, in southeastern Brazil. However, we had access to two correspondences by H. Fruhstorfer, the collector of the type material, to C. Brunner von Wattenwyl (1887 and 1888), in which he clearly states ‘Theresopolis’ to be a village in Santa Catarina State, southern Brazil. This locality now corresponds to the municipality of Águas Mornas, located about 27°45′S, 48°57′W.

Angara brauni ( Fianco, Engelking & Faria, 2020) comb. nov. Xenicola brauni Fianco et al. 2020: 585 . Holotype male, Brazil: São Paulo, Biritiba Mirim , 23.71150°S 46.05839°W (DZUP, examined).

Amended diagnosis: Angara brauni can be distinguished from its known congeners by the combination of the following characters: antennae with light and dark bands only after the fifth antennomere; black area on tegmina restricted to the costal margin; femur III> 6× longer than pronotum; proximal portion of tibia III and distal portion of femur III pallid, whitish, contrasting with nearby regions; posterior margin of male subgenital plate as wide as half of width of subgenital plate.

Additional examined material: One male ‘ Brasil, PR, Piraquara, \ Mananciais da Serra \ 25.4965°S, 48.9823°W, \ 05.XI.2021, coleta ativa \ noturna. M. Fianco’, ‘MFM053’, and ‘ Xenicola \ brauni \ det. M. Fianco v.2022 ’; one female, ‘ Brasil, PR, Piraquara, \ Mananciais da Serra \ 25.4965°S, 48.9823°W, \ 05.XI.2021, coleta ativa \ noturna. M. Fianco’, and ‘ Xenicola \ brauni \ det. M. Fianco v.2022 ’; and one female ‘ Brasil, PR, Piraquara, \ Mananciais da Serra \ 25.4965°S, 48.9823°W, \ 21.VIII.2021, coleta ativa \ noturna. M. Fianco’, ‘MFM \ 054’, and ‘ Xenicola \ brauni \ det. M. Fianco v.2022 ’.

Remarks: This is the first record of this species for the Paraná State, previously recorded only for São Paulo State, southeastern Brazil. Besides not presenting colour polymorphism, the male sampled herein presents its lateral lobes of pronotum and all epimeron and episternum black, as occurs in Angara dohrni .
