(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.
