Chen, Guang-Yu, Xu, Yue, Liao, Wang & He, Zhu-Qing, 2019, A new genus with one new species of Phaloriinae from western Yunnan, China (Orthoptera: Phalangopsidae: Phaloriinae), Zootaxa 4565 (3), pp. 443-446 : 445-446

Neophaloria dianxiensis He sp. nov.

Holotype: male, CHINA, Yunnan, Dehong, Yingjiang, Nabang , 24-iv-2018, nymph, coll. He Zhu-Qing, emergence in v- 2018.

Paratypes: 1 female, same data as holotype ; 1 male & 1 female, CHINA, Yunnan, Dehong, Ruili, Moli , 26-iv-2018, nymph, coll. He Zhu-Qing, emergence in v-2018 .

Description. Male. Head: small, frontal rostrum obviously forward convex, three ocelli oval and same in size, arranged as a triangle, maxillary palpi normal with 3rd–5th joints long. Pronotum: transverse and pubescent, anterior margin straight, posterior margin nearly straight (middle arced and lateral parts angled), forewing with five oblique veins, mirror large with two dividing veins, the upper one straight and lower one curved, apical field nearly as long as mirror in vertical, lateral field wide and inwards folded, hind wings almost as long as forewing; legs long, tympanum on both sides of tibiae with outer one little smaller, 4 pairs of dorsal spurs on hind tibiae, three inner apical spurs long (upper one longest) and three outer spurs short (middle one longest), length of the first tarsal segment as long as the second and the third tarsal segment. Abdomen: small and totally covered by forewing, cerci long and straight. Genitalia: see the description of the genus character.

Female. Similar to male, veins on dorsal field of forewing parallel, with cross vein equably distributed, ovipositor straight, longer than forewing, and little upwards curved, teeth on ventral side of apical part.

Coloration. Body brown, head and pronotum black, femur brownish, tibiae black and white alternated, cerci yellow ( Fig. 2 B–D).

Variation. The males from Moli are little different in the dividing vein. The lower dividing vein is nearly straight, but that of holotype is curved ( Fig. 2 BC).

Etymology. dianxiensis means western Yunnan in Chinese language.

Measurements (in mm). Male: body length (to forewing) 16.90–18.42, pronotum length 2.76–2.85, forewing length 13.47–14.69, hind femur length 10.59–11.54.

Female: body length (to forewing) 15.09–15.57, pronotum length 2.42–2.74, forewing length 11.27–11.69, hind femur length 10.98–12.34, ovipositor length 5.45–5.51.

Songs. Holotype (from Nabang), 26 o C. The song is continuous with 0.0756± 0.0002s cycle repeatedly (=13.24 pulses/sec) as in Fig. 4 A .

Paratype (from Moli), 25 o C. The song is little faster with 0.0613± 0.0002s cycle repeatedly (=16.32 pulses/sec) as in Fig. 4 B .

DNA barcode. COI genes of four individuals are sequenced including Holotype. Only 2 SNPs were detected in 658bp of COI fragments. Thus, we consider these are same species from Nabang and Moli, though the dividing vein is different.
