Yalvaciana unal sp. nov

Fig: (A–T)

Description. Male: Medium to large sized, dark down; tegmina not crossing the half of abdomen, apical part with distinct longitudinal veins and more or less apically pointed, hind wing insignificant ( Fig. A–B ); antenna long as long as body; ( Figs. A–D ); fastigium broad and surpassing the first antennal segment ( Fig. E ); eyes large more or less spherical and bulging outwards; pronotum depressed dorsally, compressed laterally, paranota more or less rounded with a distinct light band, both anterior and posterior ends rounded, shoulder excision indistinct, metazona with distinct median keel or carina ( Fig. C–E ); prosternum without spine; mesosternum with two long conical lobes and metasternum wide basally with small triangular incision apically (Fig. 6); fore tibia with three dorsal spines outside, two rows of evenly distributed six spines ventrally; mid tibia with two rows of evenly distributed six spines ventrally and two spines dorsally; hind tibia with spines on both sides (Figs. 13–14); hind tibia with four apical spurs ventrally, inner two much shorter than outer, two sub apical spurs also present ( Fig. F ); fore tibia with three spines dorsally, two rows of evenly distributed six spines ventrally, mid tibia with two rows of evenly distributed six spines ventrally, hind tibia with spines on both sides ( Fig. O–Q ); male subgenital plate broad basally lateral margin dark black in colour with median depression and a small V shaped incision apically, style small and cylindrical slightly tapering towards apex ( Fig. H ): 10 th abdominal tergite with two long processes, incised medially ( Fig. J ), cerci broad tapering apically with a spine at apex, tooth all most at middle ( Fig. L ); titillators have teeth on all surfaces.

Morphometry: (length in mm); whole body 16.11–16.25, tegmin 5.69–6.78, pronotum 6.06–6.11, pronotum width 3.83–3.86, fastigium width 2.42–2.45, fore femur 3.80–3.87, fore tibia 4.60–4.71, mid femur 6.0–6.11, mid tibia 5.05–5.12, hind femur 17.19–17.25, hind tibia 17.51–17.60.

Female: Subgenital plate as long as longer as broad with U shaped incision ( Fig. G ); 10 th abdominal tergite with a shallow rounded incision ( Fig. I ); sixth and seventh abdominal sternite unmodified; cerci long and cylindrical tapering at apex with blunt end ( Fig. M ); ovipositor long dark black with brownish base and regularly curved ( Fig. O ).

Morphometry: (length in mm); whole body 19.91–20.36, tegmin 6.32–6.41, pronotum 6.17–6.19, pronotum width 3.83–3.87, fastigium width 2.48–2.51, fore femur 4.80–4.90, fore tibia 4.93–5.08, mid femur 6.34–6.41, mid tibia 5.21–5.29, hind femur 18.91–19.05, hind tibia 18.80–18.94, ovipositor 9.81–9.90.

Remarks: The new species differs from other two species in various morphological characters: The new species differs from Yalvaciana yalvaci in the shape of tegmin, a subgenital plate of both male and female, the new species is also different from Yalvaciana allowpora in the shape of stridulatory file both stridulatory are shown in ( Fig. S & T ) and are quite different in both species, the spines on the titillators of Yalvaciana allowpora are present on apical surface where as in new species, spines are present on whole surface (Fig: K); the subgenital plate of female of Yalvaciana allowpora is as broad as long, apex with obtusely rounded incision while in new species the female subgenital plate is longer than broad with apically small U shaped incision ( Fig. G ).

Etymology: The name of the species is given after Mustafa Unal from Turkey who has major contribution on katydids and has reported a number of species.

Material examined: Holotype: Female. India: Jammu and Kashmir; Baramulla, Shranz fall (34.0784° N, 74.3925° E), 01 female, 18.08.2021, on grass, (coll. Muzamil Syed Shah).

Paratype: Female 02, male 02: Same as holotype.
