description: 3. Hendecaneura aritai (Kawabe, 1989) comb. nov.
(Figs. 3, 6)
Notocelia aritai Kawabe, 1989, Microlepidoptera of Thailand, 2: 59. TL: Thailand, Chiang Mai, Doi Pui; TD: UOP.
Description. Adult (Fig. 3). Head: Vertex brown; frons white. Antenna light brown, with grey scape. Labial palpus brown, with inner side white, second segment slightly dilated towards apex, apex with white scales, third segment porrect, grey. Thorax: Thorax and tegula grey except base with brown scales. Forewing length 7.0 mm. Forewing with ground color grey, scattered with transverse light brown streaks, termen slightly concave below apex; ocelloid patch rectangular, concolor with ground color, with inner and outer edge light brown; costa with five pairs of white strigulae from apex to costal half; other patches inconspicuous, a black line along termen; cilia brown on apex and termen, pale on tornus. Hindwing and cilia pale yellowish. Abdomen: Male genitalia (Fig. 6). Uncus broadly mound-like, with few hairs; socius long, drooping, with long hairs; valva deeply depressed and forming narrow neck; sacculus broadly dilated towards its end, with hairs on the ventral and posterior area of basal opening, sacculus angle blunt; cucullus broad triangular, setose, with marginal spines; phallus short tubular, cornuti composed of a bunch of slender deciduous spines (lost).
Male scent organs. Forewing with a brown narrow costal fold reaching before half of costa, with relatively long brown scales apically; circular pocket at base of 1A+2A vein in forewing absent. Hindwing with a tuft of hairlike scales at the base of cell on the upper side.
Specimen examined. 1♂, Yunnan Province, Pu’er City, Taiyanghe Natural Forest Park, Yuyingtang, alt. 1,450 m, 24 April 2015, coll. K. Teng, genitalia slide no. ZAH16046.
Distribution. China (Yunnan), Thailand.
Remarks. Kawabe (1989) described this species from Thailand and placed it in Notocelia Hübner. In this study, one specimen from Yunnan Province is identified as this species. In the species of Notocelia anal fold in male hindwing is present and non-deciduous cornuti are present terminally in vesica. In this species these characters are not found, so it is inappropriate to place this species in Notocelia.
Kawabe (1989) described all markings were inconspicuous in the forewing. While in this study ocelloid patch is rectangular, concolor with forewing ground color. From the adult figure in Kawabe (1989) ocelloid patch can be easily discriminated. Maybe due to ocelloid patch concolor with ground color of forewing, it resulted in all markings inconspicuous in the original description.
Through carefully checking the characters of venation and male genitalia, this species shows the integrated characters which are shared within the species of Hendecaneura. The characters of venation include forewing with all veins separate, chorda and M-stem missing, R 4 and R 5 to costa and termen respectively, M 2 close to M 3, CuA 1 bent forward and CuP rudimentary. Hindwing with Rs and M 1 stalked at basal 1/3, M 3 and CuA 1 short stalked, CuP rudimentary. Male forewing with a narrow costal fold and without a circular pocket at base of 1A+2A vein. Male hindwing without anal fold, but with a tuft of hair-like scales at the base of cell on the upper side. The main characters of male genitalia are uncus broadly mound-like, socius long and drooping, valva with narrow neck, sacculus broadly dilated towards its end, sacculus angle blunt and cucullus broad triangular. Though a circular pocket at base of 1A+2A vein is absent in male forewing, it is transferred to Hendecaneura yet based on this species showing the similarity with the species of Hendecaneura. This species is firstly reported from China.
This species is similar to H. simplex Zhang & Li in appearance but can be distinguished by male forewing without a circular pocket at base of 1A+2A vein, the broadly mound-like uncus and broad triangular cucullus in the male genitalia. While in H. simplex, male forewing bears a circular pocket at base of 1A+2A vein, uncus is produced into two weak processes and cucullus is irregularly oblong.
And this species also resembles H. tricostatum Zhang & Li in the characters of male genitalia and male forewing without a circular pocket at base of 1A+2A vein, but can be distinguished by simple forewing pattern and sacculus broadly dilated towards its end. In H. tricostatum forewing bears basal patch, a triangular patch on dorsum and ocelloid patch distinctly, male forewing has a circular pocket at base of 1A+2A vein and sacculus is not dilated towards its end.
