MATERIAL. Holotype – ♂, Vietnam: Kon Tum Prov., Kon Plong Distr. , 14

km N of Kon Plong Town, 14º43ʹ20ʹʹN, 108º18ʹ58ʹʹE, 1030 m, 9–23.IV 2015, A.

Abramov. Paratype – ♀, same data .

DESCRIPTION. Male. Body structure also rather similar to that of both previous congeners ( X. mada and X. shcherbakovi ), but coloration somewhat different: sparse small spots on antennal flagellum, posterior area on pronotal disc, distal part of tegminal stridulatory apparatus and a pair of apical dots on apex of hind femur brown to dark brown; two pairs of narrow lateral stripes on pronotal disc more or less brownish

(a pair of stripes located on anterior part of disc rather light; a pair of stripes located on posterior half of disc slightly darker and fused with dark posterior area of this disc); area on membrane of each tympanum, stripe on each tegmen along its anal edge (except for stridulatory apparatus) and several very small spots on distal half of lateral tegminal field light brown; apical area on all tibiae and subapical segment of all tarsi slightly darkened. Shape of last tergite more similar to that of X. shcherbakovi than to that of X. mada , but its posteromedian process distinguished from that of both these species by smaller or apically rounded distal part having very small and asymmetrical (but not hooked) ventroapical lobule, by presence of deep cavity between this process and small lobule-like epiproct, by asymmetrically concave ventral surface of latter process, and by small spinule-like tubercle located on right dorsolateral part of base of this process ( Figs 45, 46 ); cerci with proximal part complicated (having additional dorsomedial both rounded lobule and small fold near it), and with distal part of right cercus widened and lamellar as well as corrugated and having deep notch and a few small projections (left cercus with distal part probably damaged during nymphal stage) ( Fig. 45 ); genital plate without any projection between styles ( Fig. 48 ).

Female. General appearance as in male but with smaller and sparser spots on antennal flagellum, almost without pattern on pronotum as well as darkened parts on dorsal tegminal field and along anal edge of lateral tegminal field, with somewhat lighter dots on both apical lobules of hind femur, without tegminal stridulatory apparatus, and with last tergite and epiproct as well as cerci unspecialized; genital plate with small and acute tubercle on basal part (this tubercle very similar to that of female of X. beybienkoi , X. mada and X. bituberculata Ebner, 1939 ; Figs 47 , 70 );

ovipositor as in Fig. 70 .

MEASUREMENTS. Length (in mm). Body: ♂ 12.5, ♀ 13; body with wings: ♂

24.5, ♀ 25.5; pronotum: ♂ 2.2, ♀ 3.8; tegmina: ♂ 19, ♀ 21; hind femora: ♂ 10.5, ♀

11.5; ovipositor 10.

COMPARISON. The new species differs from all the other species of this subgenus in the presence of distinct darkened marks on the antennae and pronotum (at least in male) and the above-mentioned characters of posteromedian process of male last tergite as well as more complicated structure of proximal and distal parts in the male cercus.

ETYMOLOGY. Name of this species is the Latin word “ornata” (ornated) due to its coloration.
