Doryloxenus songzhigaoi View in CoL sp. n. Fig. 3

Type material.

Holotype: China: ♂, labeled 'CHINA: Yunnan, Tengchong City, Mingguang Town (明光乡), Zizhi Vill. (自治村), Donghe (东河), alt. 2400m, 25°42'57"N, 98°35'42"E, 30-IV-2013, X.-B. Song leg., from a colony of Dorylus orientalis / HOLOTYPE [red], Doryloxenus songzhigaoi sp. n., Song & Li det. 2014, SNUC’. Paratype: China: 3♂, same data as holotype, bearing the following label: 'PARATYPE [yellow], Doryloxenus songzhigaoi sp. n., Song & Li det. 2014'. (SNUC).

Comparative notes.

Doryloxenus songzhigaoi is most similar to Doryloxenus nepalensis Naomi in general appearance, but can be easily separated from it by the different macrochaetotaxy of abdominal tergites II–VIII. The new species can be distinguished from the other congener known from the Gaoligong Shan, Doryloxenus yunnanus , by the slender tergite VIII, rounded apex of sternite VIII, and different shape of the aedeagal median lobe.

Description.

Body (Figs 3A, 4D) smooth, glabrous. Coloration: Light reddish-yellow overall.

Forebody shaped as in Fig. 3A, with sparse punctation. Head shaped as in Fig. 3B. Pronotum (Fig. 3A) about 1.71 times as wide as long. Elytra (Fig. 3A, C) about 2.55 times as wide as long. Abdomen wedge-shaped; posterior margins of tergite II–VI with a row of very long yellowish setae; abdominal tergite VII (Fig. 3D) truncate at apex, with 2 pairs macrochaetae at middle and 3 pairs near apex; tergite VIII (Fig. 3E) slightly truncate at apex, with 1 pair of lateral macrochaetae and 2 pairs near apex; sternite VIII shaped as in Fig. 3F. Macrochaetotaxy of abdominal tergites II–VIII: 4, 2, 4, 4, 4, 10, 6.
