2. Bianigryllacris Cadena-Castañeda, 2019 View in CoL (边氏蟋•属)
Bianigryllacris: Cadena-Castañeda. 2019 . Zootaxa, 4605(1): 38.
Type species: Apotrechus trilobus Bian & Shi, 2014
Diagnosis. Body small to medium, form robust, apterous. Middle ocellus absent, lateral ocelli absent or inconspicuous, with poorly defined. In male, ninth abdominal tergite enlarged, cuculli-form, posterior area obviously divided into 2 spine-shaped lobes, distinctly curved ventrad, emargination between them deep and triangular; subgenital plate without styli, posterior margin with a deep and wide concavity and with apices digitate laterally; cerci short. In female, subgenital plate broad and long.
Discussion. Liu & Yin (2002) were firstly reported the Apotrechus to the Chinese fauna, and the latter authors ( Liu & Bi, 2008; Liu & al., 2010 a; Liu & Shi, 2012; Guo & Shi, 2012; Bian & al., 2014; Liu et al., 2015a) described 7 Chinese species under Apotrechus . Cadena-Castañeda (2019) erected the Bianigryllacris including all the Chinese species of Apotrechus . The genus have obviously difference from Apotrechus in: posterior margin of male ninth abdominal tergite divided into 2 spine-shape lobes, which directing ventrad, between them triangular concave; posterior margin of male subgenital plate with a deep concavity, the lateral lobes digitate apically; female subgenital plate obviously sclerotised without membranous area. In Apotrechus , male ninth abdominal tergite bulbate, apex weakly divided, posterior margin of male subgenital plate projected in the middle, the lateral lobes with or without tubercles apically; female subgenital plate very soft, median area with a soft area.
Species included. The genus is endemic to China with 8 known species.
