( Figs. 1–8 )

Holotype: ♂, paratypes 5♂, 4 ♀, China, Heilongjiang, Mohe, Arctic Village, edge of a pine forest. 53° 27' 57. 28" N – 122° 21' 41. 92" E. 22-VII-2012, collected by Jun-Jian Li & Bing-Zhong Ren.

Male. Medium size (body length 16 mm) ( Fig.1 ). longipennate. Head in dorsal view, slightly shorter than pronotum ( Fig. 2 ). Fastigium of the vertex with dorsal median carinula; right triangle apex. Lateral foveola obvious and quadrangular; length more than 3.0 times width ( Fig. 3 ). Frontal costa oblique in profile view; with shallow longitudinal sulcus from median ocellus to clypeus. Interocular space wide, 1.4 times width of frontal costa between antennae. Eyes oval, vertical diameter 1.5 times horizontal diameter and 1.5 times length of subocular furrow ( Fig. 3 ). Antennae stilbiform with 23 joints, longer than the head and pronotum together. Anterior margin of pronotum straightand posterior margin arc-shaped; both median carina and lateral carina were obvious, and lateral carina arc-shaped at prozona, the widest distance between two lateral carinae 2.0 times the narrowest distance; prozona slightly shorter than metazoan ( Fig. 2 ). Prosternum flat, mesosternal space subsquare and metasternal lobes distant. Tegmina and hind wings developed, tegmina obviously surpassing the apex of hind femur; the base of protoloma expand, the tip of precosta area extending beyond half of the tegmen; width of costal area about 1.5 times width of subcostal area, and media area about 1.2 times cubital area ( Fig. 4 ). Fore tibia not enlarged and with sparse villus. Tympanum developed, vertical diameter 4.0 times horizontal diameter. Epiproct subtriangular. Subgenital plate short-conical. Cerci long and slender, its length about 4.5 times width. Phallic complex and epiphallus showing in ( Figs. 6–8 ).

Female. Larger in size (body length 19 mm) ( Fig. 5 ). Antennae shorter than in males, approximate to head and pronotum together. Tegmina shorter, not surpassing the apex of hind femur. Ovipositor valves short and thick, their margins without tooth, the apex of valves hooked slightly.

Coloration. Body yellow brown. The enlargement of antenna black, and the top white. Head and pronotum lightcolored, the lateral dark-colored. The front of tegmen rosy, the end yellowish-brown. The end of the abdomen red.

Measurements (mm): Length of body: ♂ 14.5–16.1, ♀ 17.7–19.6. Length of pronotum ♂ 3.1-3.6, ♀ 3.6–4.4. Length of hind femur: ♂ 9.7–10.3, ♀ 10.7–12.9. Length of tegmina: ♂ 12.8–14.2, ♀ 13.9–15.3.

Diagnosis. The new species is allied to Gomphocerippus rufus (Linnaeus, 1758) . The major differences are listed in Table 1.

Habitat. The habitat of the localities is in the bushes of artificial pine forest understory within the southern parts of the Greater Khingan range in Mohe, China.

Etymology. The species is named from Latin, longus (“long”) + penna (“wing”), referring to the new species with long wings.
