Ultragryllacris alboclypeata alboclypeata Gorochov et Dawwrueng, 2015 stat. nov. Figs. 1, 6–8, 29, 38, 47, 56, 64, 72, 81–82

Ultragryllacris pulchra alboclypeata Gorochov et Dawwrueng in Gorochov et al., 2015; Ingrisch, 2018; Cadena-Castañeda, 2019

Materials examined: 4 males (AUP-02015–AUP-02018), 1 female (AUP-02019); Thailand, Nakhon Sawan Prov., Mae Wong District, Than Mayom, 400–450 m, 20–21.IX.2020, coll. P. Dawwrueng and P. Pawangkhanant (AUP) .

Description of male (nov.). General appearance (including armament of legs) similar to that of holotype (female) (Figs. 1, 6), but one male distinguished from all other known specimens in absence of black transverse band above median ocellus (Fig. 7). Large unpaired process of 9th abdominal tergite distinctly narrowing toward apex, elongately triangulated in dorsal view but truncated at apex (Fig. 29), almost straight (slightly sinuate) in profile (Fig. 38), dorsally and ventrally setose, ventrally also with median furrow and deep transverse fold at base (this fold having a pair of short sclerotized ridges with small teeth along its posterior edge; Fig. 47); epiproct with a pair of small lobules nearly middle part which connected to the inner side of each paraprocts (Fig. 47); subgenital plate very short, broad, with posterior part rounded and having shallow median notch, and with short styli placed at lateral parts of posterior edge (Fig. 56).

Comparison. Differences of this taxon from all the other congeners on the basis of its males and females are given in the above-mentioned key to species and subspecies of this genus.

Discussion. This taxon was described after one female (holotype) as a subspecies of U. pulchra from Kamphaeng Phet Prov. on the base of its general appearance similar to that of female of nominotypical subspecies but distinguished by more developed black ornament on epicranium and whitish clypeus (Gorochov et al., 2015). Later we collected additional males and female in the area near type locality of U. p. alboclypeata; the female is in accordance to the description of this taxon, but the males show more significant differences from male of U. p. pulchra . Therefore, here we raised this subspecies to species status, as U. alboclypeata Gorochov & Dawwrueng, 2015, stat. nov.
