251B7147FE78FFB4FF1FFA24FBE599FB.taxon	diagnosis	Diagnosis. This species is externally similar to H. orbiculosa Inoue, 1978 and H. simplex Warren, 1899, but can be distinguished by transversal lines tinged with red on veins; by the discal spot smaller, dark green rather than presenting as a white ring (variable in size) in H. orbiculosa. In male 8 th abdominal sternite, it can be separated by posterior margin truncate (Fig. 38) rather than with lunate incision toward anterior part in H. simplex (Fig. 39) or with two lateral, sclerotized processes in H. orbiculosa (Fig. 40). In genitalia, it can be distinguished by harpe strongly sclerotized with apex straight and acute rather than less sclerotized, short with apex blunt in H. simplex and strongly sclerotized with apex hook-like in H. orbiculosa; by three spinose patched arising from vesica rather than two in H. simplex and absent in H. orbiculosa; by lamella postvaginalis fan-shaped rather than separated as two plates in H. orbiculosa and curved band-like in H. simplex; by corpus bursae short pear-like, strongly sclerotized rather than spindle-like and strongly wrinkled in H. simplex and short sac-like and membranous in H. orbiculosa.	en	Chang, Wei-Chun, Wu, Shipher (2013): Review of the genus Hemistola Warren, 1893 in Taiwan with notes on an unusual conifer-feeding larva and descriptions of three new species (Lepidoptera, Geometridae, Geometrinae).

This species was recorded in Japan, Korea, SE Russia and Taiwan (Han & Xue 2009; 2011; Nakajima, 2011). The record from Taiwan was given by Inoue (1978) based on examination of a single male specimen from “ Jen-ai-hsian ”, Nantou, vi – vii. 1958 (ex M. Okano). However, no specimen was illustrated in that report and presently no additional material was acquired during our specimen sampling of Hemistola from Taiwan. We here regard that specimen as a misidentification of an externally similar species, H. orbiculosa, and omit H. tenuilinea from the Taiwanese fauna until further voucher specimens can be obtained. We also illustrate the Japanese H. tenuilinea for comparison. In external appearance, H. tenuilinea (Fig 15, 16) differs from H. orbiculosa by the yellowish transversal lines and discal ring-like spot on its wings. The male genitalia (Figs 33, 34), male 8 th sternite (Fig. 42) and female genitalia (Fig. 49) of H. tenuilinea also present distinct differences from that of Taiwanese species.

251B7147FE77FFB9FF1FFDADFC369DA2.taxon	distribution	Distribution and bionomics. This species occurs in low to mid-elevation primary broad-leaved forests of northern and central Taiwan. The adults occur from mid May to July, and are possibly univoltine. Its sibling species H. dijuncta feeds on Ligustrum tschonoskii (Oleaceae) (Parsons et al. 1999). The Ligustrum plants occurring in the distribution range of the new species include L. pricei and L. morrisonense.	en	Chang, Wei-Chun, Wu, Shipher (2013): Review of the genus Hemistola Warren, 1893 in Taiwan with notes on an unusual conifer-feeding larva and descriptions of three new species (Lepidoptera, Geometridae, Geometrinae).
