Head not exerted or exerted above pronotal surface. In dorsal view, fastigium of vertex between eyes of variable width – either 1) narrower than or 2) equal to or 3) wider than width of compound eye; anterior margin of fastigium truncate, not surpassing anterior margin of eye; median carina of vertex visible anteriorly; fossulae slightly deep or not; lateral margins of vertex slightly raised above dorsal margin of eyes as horns or not. In frontal view, frontal costa bifurcated between compound eyes, just behind paired ocelli, scutellum (longitudinal furrow) either 1) narrower than or 2) equal to or 3) slightly wider than antennal groove (AG) diameter. In lateral view, frontal ridge concave and invisible between eyes, protruding anteriorly and broadly rounded between antennal grooves; lateral (paired) ocelli located from lowest third of compound eye height to between lower margins of eyes. Antennae long, filiform, antennal grooves (AG) inserted far below or slightly below inferior margin of compound eyes. Eyes globose. Pronotum smooth and finely granulated, in dorsal view AMP truncated, small FL 1, FM; pronotal discus subulate posteriorly and extending beyond apex of hind femora; dorsum elevated behind shoulders like a hump or flat; pronotal MC of variable shape – either 1) MC of pronotum compresso-elevated, upper margin of pronotum in profile with one to two swellings anteriad of shoulders, MM 1 like a hump and large, PM small (e. g. X. stylata, X. motuoensis, X. hunanensis, X. dromadaria and X. cliva) or 2) MC of pronotum straight (e. g. X. aruna, X. dohrni and X. ophthalmica) in profile. PML of pronotum with tegminal and ventral sinus, PML of pronotum produced outwards (e. g. X. dubia) or turned downwards (e. g. X. dromadaria), or obliquely truncate behind and right angled (VL). Tegmina long oval, apex round. Wings generally extending to apex of pronotal process. Legs. Fore and middle femora slightly compressed, margins finely serrated, with carinated and straight or undulated dorsal and ventral margins.

03C63657235C3C1DFC25EB2FFD1678EE.taxon	diagnosis	Differential diagnosis. Xistrella can be easily distinguished from other genera of the subfamily Metrodorinae by a vertex not narrowly truncate in frontal view, depressed between the eyes, vertex horn drawn out or not; antennae clearly inserted below the inferior margin of eyes and considerably long; pronotum between the shoulders strongly elevated to an obtuse gibbosity or slightly elevated in the posterior part of shoulders. Xistrella Bolívar, 1909 is morphologically similar to the genera Xistra Bolívar, 1887 and Mazarredia Bolívar, 1887, as well as to the genera Paraphyllum Hancock, 1913 and Bermania Storozhenko, 2012. In Xistra, the vertex horn is distinctly raised above the dorsal margin of eyes and the vertex is deeply depressed between eyes in frontal view; pronotum between the shoulders is not elevated to an obtuse gibbosity (in frontal view, the vertex horn slightly raised above the dorsal margin of eyes or not and the vertex slightly depressed or not depressed between eyes; pronotum between the shoulders generally strongly elevated to an obtuse gibbosity in Xistrella). In Mazarredia, head is distinctly exerted above the pronotal surface; antennae short, antennal grooves inserted between the ventral margins of the compound eyes (head not exerted or a little exerted above the pronotal surface; antennae long, antennal groove inserted below the ventral margin of eye in Xistrella). In Paraphyllum, pronotum has strongly raised median carina, usually with leaf-like depression; the anterior margin is produced over the head in profile (pronotum never evenly depressed in a leaf-like pattern, the anterior margin truncated and not produced over the posterior margin of the compound eyes in Xistrella). In Bermania, pronotum has strongly angularly projecting FM in dorsal view; FM almost reaches the anterior edge of eyes (pronotum in dorsal view with truncated anterior margin; FM is not produced over the posterior edge of eyes).	en	Xin, Lei, Deng, Weian (2019): A new species and a new record of Xistrella from China (Orthoptera: Tetrigidae).
