Teleogryllus (Teleogryllus) albipalpus He sp. nov.

Holotype: male, CHINA, Yunnan, Baoshan, Mangkuan town , 28-iv-2018, coll. He Zhu-Qing.

Paratypes: 1 male & 1 female, same data as holotype .

Description. Male. Typical Gryllinae cricket appearance. Head: frontal rostrum as three times wide as the 1st antennal joint, median ocellus flat, and located little lower than lateral ocelli, maxillary palpi normal with 3 rd –5 th joints long; thorax: pronotum almost square in disc and as wide as head, disc with pubescence, anterior and posterior margin almost straight, rounded borders between disc and lateral lobes, tympanum on outside only, forewing with short apical field, the length of mirror equal to width, hindwing little longer than forewing. Hind tibia with 6–7 pairs of dorsal spines. Genitalia: Epiphallus elongate with flat apical part (similar to Macroteleogryllus spp.), ectoparamere narrow (similar to Brachyteleogryllus spp.) and totally covered by epiphallus as in Fig. 3 A–C.

Female. Similar to male, ovipositor elongate and straight.

Coloration. Body color overall darkness. 1 st –3 rd joints of maxillary palp almost black, 4 th –5 th joints white.

Variation. Macropterous form individuals appeared occasionally in lab cultures ( Fig. 2 GH).

Nymph. ( Fig. 2 C–F)

First instar: Overall body color black. Anterior half of metathorax brown, posterior half whitish. Basal portion of cerci white ( Fig. 2C ).

Second instar: Appearance of body and metathorax as the first instar. Hind femur yellowish with black longitudinal striae ( Fig. 2D ).

Penultimate instar: Body color overall brown. Posterior margin of metathorax white. Hind femur brown. Length of ovipositor in dorsal view as long as one abdominal segment ( Fig. 2E ).

Ultimate instar: Body color darkness. Metathorax almost black. Anterior margin of first abdominal segment white. Length of ovipositor in dorsal view as long as four abdominal segments ( Fig. 2F ).

Etymology. albipalpus is used to describe its 4th–5th joints of maxillary palps as white.

Measurements (in mm). Male: body 18.04–18.42, pronotum length 3.91–4.42, forewing length 10.61–10.70, hindwing length 13.10–13.72, hind femur length 13.01–13.56; Female: body 17.54, pronotum length 3.97, forewing length 8.80, hindwing length 9.15, hind femur length 12.29, ovipositor length 13.55.

Distribution. China (Yunnan). Song. Calling song with simple chirps. One chirp is about 0.298± 0.013s, and pause about 2.025± 0.258s. Each chirp includes 5 pulses with the first pulse very weak ( Fig. 3 DE).
