(Fig.1 A −C, Figs. 2−4)

Neolygus bui Lu & Zheng, 2004: 387, 739 (n. sp.).

Diagnosis. Readily recognized by the comparatively small size; yellowish-brown to pale castaneous basic coloration; dark mid-ventral stripe on antennal segment I (Fig. 2); variable dark maculae or stripes on mesoscutum, scutellum, corium and clavus (Fig. 1 A–C); always darkened apex of cuneus; widely darkened apical half of metafemur (its darkened part often reducing to ring-like bands in Ƥ as in Fig. 1 C); and widely castaneous abdomen. The dorsal surface is more or less tinged with olive when alive. Male genitalia (Figs. 3, 4): Left paramere sensory lobe expanded apically, with a conical protuberance; right paramere with hooked, sharply pointed hypophysis (Fig. 3). Endosoma with C-shaped spiculum and narrow ventral sclerite (Fig. 4). Female genitalia: Not examined; most available female specimens are teneral.

Measurements. 3/ Ƥ: Total body length 4.2–5.4/ 4.3–4.9; head width across eyes 0.88–1.12/ 0.94–0.95; vertex width 0.22–0.29/ 0.32–0.35; lengths of antennal segments I–IV 0.43–0.48, 1.44–1.68, 0.70–0.86, 0.51–0.55/ 0.42–0.46, 1.36–1.41, 0.70–0.76, 0.51–0.53; labial length 1.46–1.52/ 1.50–1.52; basal pronotal width 1.44–1.71/ 1.66–1.70; width across hemelytra 1.67–2.00/ 1.88–1.98; lengths of metafemur, tibia, and tarsus 1.52–1.71, 2.28–2.53, 0.57–0.63/ 1.61–1.64, 2.28–2.40, 0.53–0.57.

Distribution. China (Shaanxi and Sichuan Provinces.), N. India, Nepal (from subboreal deciduous forests to warm temperate zone), Taiwan.

Biology. Collected mainly from inflorescences of Citrus sp. ( Rutaceae), Quercus spp. ( Fagaceae), and some unidentified broadleaves; however, immature forms are yet to be confirmed from these plants. The adults are occasionally attracted to light. A bivoltine life cycle is assumed for this mirid.
