Diagnosis.

This species is similar to P. obfuscalis in appearance, but can be distinguished by the larger size (forewing length 13.0–19.0 mm, wingspan 33.0–35.0 mm), antenna with ventral cilia approximately as long as flagellomere diameter in male, postmedial line of fore and hind wings punctiform between M 2 and CuA 2 (Fig. 7 View Figures 6–11 ); uncus nearly triangular (Fig. 14 View Figures 12–16 ), gnathos thick, finger-like (Fig. 14 a View Figures 12–16 ), costa of valva without a cluster of setae medially, fibula densely covered with setae (Fig. 14 b View Figures 12–16 ), phallus posteriorly with a nail head-like protruding sclerite (Fig. 14 c View Figures 12–16 ) in male genitalia (Fig. 14 View Figures 12–16 ); ductus bursae ~ 4 × length of corpus bursae, signum absent in female genitalia. In P. obfuscalis , the forewing length is 8.0–15.0 mm and wingspan is 25.0–33.0 mm, the ventral cilia of antenna is ~ 1 / 3 length of flagellomere diameter in male, the postmedial lines of the fore and hind wings are dentate between M 2 and CuA 2 (Fig. 6 View Figures 6–11 ). In male genitalia, the uncus of P. obfuscalis is semicircular (Fig. 12 View Figures 12–16 ), the gnathos is reduced to a narrow band (Fig. 12 a View Figures 12–16 ), the costa of valva bears a cluster of long setae medially (Fig. 12 View Figures 12–16 ), the fibula bears setae medially (Fig. 12 b View Figures 12–16 ), the phallus posteriorly has a finger-like protruding sclerite (Fig. 12 c View Figures 12–16 ); in female genitalia, the ductus bursae is ~ 2 × as long as the corpus bursae and a rounded signum is present (Fig. 13 View Figures 12–16 ).

Distribution.

China (Yunnan, Hainan, Fujian, Guangdong, Taiwan) ( Lu and Guan 1953; Xu and Du 2016), Japan, Indonesia, India, Myanmar, Sri Lanka, Malaysia, Thailand, Timor Leste, Philippines, Caroline Islands, Papua New Guinea, Pakistan, Australia ( Hampson 1896; Shibuya 1928, 1929; Klima 1939; Inoue 1982; Wang and Speidel 2000).

Remarks.

The uncus and fibula of this species are narrower than in other species of this genus. We found that the external morphology and male genitalia characters of Patania clava were the same as those of Purpurata iopasalis . Their distinctive characters were that the postmedial lines of the fore and hind wings were punctiform between M 2 and CuA 2, the gnathos was thick finger-like and setose apically ( Walker 1859; Inoue 1982, Yamanaka 1998; Xu and Du 2016). Therefore, Patania clava is synonymized with Botys iopasalis . For a detailed description of this species see Walker (1859) and Xu and Du (2016). Moreover, Xu and Du (2016) described that the labial palpus of Patania clava was pale yellow with a brown patch near the base, while we observed that this species had a subapical brown spot beside this basal spot, and the subapical brown spot was obscured in some individuals.
