2.7 Atlanticus (Sinpacificus) fallax He View in CoL sp. nov.
Holotype: 1 male, CHINA, Zhejiang Prov., Taishun, Wuyanling , 14-vii-2017, coll. He Zhu-Qing.
Paratypes: 1 male, nymph, CHINA, Zhejiang Prov., Jingning, Wangdongyang , 15-vii-2017, coll. He Zhu- Qing ; 1 female, nymph, CHINA, Zhejiang Prov., Jingning, Wangdongyang , 15-vii-2017, coll. He Zhu-Qing .
Description. Pronotum saddle-shaped, disc rectangle in 1/3, and widened gradually with the posterior margin arc, lateral lobes of pronotum deepest in middle, posterior margin oblique with central concavity, tegmen as long as pronotum and extending to the 7th or 8th abdominal tergum. Leg spination, fore femora with 2 interior ventral spines on left and 1 on right, middle femur with 1 external ventral spines, hind femur with 3 interior spines on outer ventral margin and 4 on inner ventral margin, fore tibiae with 3 dorsal spines on outer exterior margin, and 1 spine on the inner exterior margin, 6 spines on both ventral margins, middle tibiae with 3 dorsal spines on outer exterior margin, and 2 spine on the inner exterior margin, 6 ventral spines on both margins, hind tibiae with 21 exterior and 17 interior spines on dorsal margins, 7 and 9 spines on ventral margins. Tenth abdominal tergum with a small U shape notch on central, cerci curved with a small tooth in the middle ( Fig. 3D View FIGURE 3 ).
Female Nymph, similar to male, no tegmen, ovipositor nearly straight.
Coloration. Brown, upper side of lateral lobes of pronotum black, head and hind femur yellow.
Variation. Neither two nymphs has spine on the inner exterior margin on fore tibiae. It is unclear whether it will appear as it matures.
Etymology. The name fallax is used to emphasize its similarity to A. (S.) fengyangensis Liu, 2013 .
Measurements (in mm) male: body length 31.2, pronotum length 11.9, tegmen length 13.6, hind femur length 32.9; female (nymph): body length 23.3, pronotum length 10.5, hind femur length 29.8, ovipositor length 22.5.
Distribution. China (Zhejiang)
Song. The song of this species is similar to that of A. (S.) magnificus with 0.25s chirp cycle duration. But in every chirp, 6 or 8 pulses are clearly present.
Note. This new species is very similar to A. (S.) fengyangensis Liu, 2013 ( Fig. 2 View FIGURE 2 CD), but the new species has one more row of spines on the fore tibia. There are also differences in song and the shape of the cerci ( Table 2, Fig. View FIGURE 3
3CD). The ventral surface of the abdomen is red when alive, while that of fengyangensisi is yellow or lime. This species is distributed in the southernmost part of Zhejiang, and there seems to be geographic isolation on two species ( Fig. 4 View FIGURE 4 ).
