Edosa subochraceella ( Walsingham, 1886)

( Figs 1 , 17 a, 21, 52)

Tinea subochraceella Walsingham, 1886: 464 ; Meyrick, 1934: 42; Davis, 1992: 65.

Haplotinea subochraceella: Diakonoff, 1967: 286 .

Edosa subochraceella: Robinson & Nielsen, 1993: 198 ; Robinson & Tuck, 1996: 11; Gaedike, 2012: 174 .

Material examined. CHINA: Hainan Province: 1 ♂, Datian Conservation Zone (19°42΄N, 109°47΄E), 25 m, 30.xi −2.xii.2009, leg. Zhaohui Du & Linlin Yang, genitalia slide No. YLL10085.

Diagnosis. Adult ( Fig. 21 ). Wingspan 12.0 mm. Edosa subochraceella is characterized by the twisted uncus lobes with distal 1/3 strongly contorted, forming a triangular section and a melanized nodule; the valva varying from subovate to rounded triangular, with finely coarse nodules below or on costal margin, the obvious ventral lobe, the absence of the basal flange; the trapezoidal juxta; the stout, double-walled aedeagus with inner wall tubular, outer wall forming shallow subapical carinae; the bulbus ejaculatorius 7.0× length of the aedeagus, subdistal section semicircularly hypertrophied, distal section hypertrophied, 0.5× width of the subdistal section, deep cup-shaped ( Fig. 52 ). Edosa subochraceella is similar to E. varians sp. nov., but can be distinguished by the valva without process on the costal margin, while the valva has a triangular to hillock-shaped process on the costal margin in the latter species.

Distribution. China (Guangdong, Hainan, Taiwan), Burma, India, Nepal, Philippines, Sri Lanka.

Remarks. Robinson (2008a) treated the male specimens of Haplotinea subochraceella ( Walsingham, 1886) from Philippines in Diakonoff (1967) as E. williamsonella Robinson, 2008 .

Gaedike (2012) figured the male genitalia of E. subochraceella , which shows the variations of the uncus lobe and the valva ( Gaedike 2012, Figs 73−79 ). The subovate valva in our specimen is within the range of the variation.
