This species differs from all described Anisopleura species by the presence of two long processes on the posterior lobe of prothorax, both in male ( Fig. 1a ) and female ( Fig. 1d, f, g ). The female is described here for the first time. Description of female. Posterior lobe of prothorax with two processes as in the male ( Fig. 1d, f, g ). The color pattern of head, thorax and legs is as in the male ( Fig. 1d, e ), apart from the antehumeral stripe, the anterior end of which has an oval shape with a dark core and which tapers off earlier towards the posterior end of mesepisternum ( Fig. 1d ). Wings ( Fig. 1h ) are hyaline with black venation. The number of Ax is 18–19 in both wings. Abdomen ( Fig. 1d ) is black with pale yellowish lateral markings on abdominal segments as follows: S1–2 have a large oblong marking; S3–7 have an oval anterior marking, and a thin stripe running along the lateral suture, becoming thinner towards their posterior ends; S8 is black with a small oval spot near posterior margin; and S9–10 are wholly black. Ovipositor black, thick and robust as in Fig. 1d . Measurement (in mm). HW 32; abdomen (incl. appendages) 29. Distribution. Vietnam ( Thua Thien-Hue , Quang Nam , Quang Tri , Lam Dong and Khanh Hoa Provinces).
