Introduction The genus Hadennia, erected by MOORE (1885), is a diverse group, distributed mainly in the Oriental Region, with some species extending to the Pacific coasts of the Palaearctic Region. The species, H. kimae was described by HOLLOWAY (2008), who assessed its generic placement as doubtful, due to the highly atypical male genitalia, as the clasping apparatus lacks the spherical structure between bases of valvae, and bears a large costal process. The aim of this publication is to give the description of the hitherto unknown female of this species which may clarify the taxonomic relegation of the species. Materials and Methods The examined specimens belong to a huge material collected by the late Dr E.W. Diehl. They were incorporated into the collection of the Heterocera Sumatrana Society but, later on, these specimens were donated to the Hungarian Natural History Museum, Budapest (HNHM). Genital dissection was made from dry, pinned and mounted specimens, via the conven­ tional method (i.e. maceration in KOH solution). Permanent slides were prepared, the chitinous structures were stained with eosine and mounted in Euparal. The slides were digitised with a Nikon Super Coolscan 5000 scanner, and the adults were photographed with an Olympus B 101 camera. The program Adobe Photoshop CS2 was used for adjusting the images.

Description of the female External appearance (Figs. 1, 2, 4). Wingspan 33^0 mm, length of forewing 16.5-20 mm. Antennae filiform, with cilia and setae arising from the ventral quarter of each segment; setae 1.5 times longer than, cilia half as long as the diameter of flagellum. Labial palps moderately long; 3rd segment straight, narrow, slightly shorter than 2nd, directed upwards at obtuse angle; 2nd segment hardly curved upwards, directed forward. Body rusty brown, abdomen slightly lighter and more greyish than the concolorous head and thorax. Wings with characteristic pattern. Forewing: basal half light brownish grey, with some reddish shade and slight bluish tinge; ante- medial line straight, perpendicular to dorsum, dark rusty red in colour; medial line parallel with antemedial, very narrow, disappearing below cell; postmedial line varying from straight and slant to slightly curved in shape, its colour like that of antemedial; subterminal line narrow, light bluish grey, arising from apex, making a huge protrusion towards termen between veins M2 and Cul; terminal line dark grey, zig-zagging; area between postmedial and subterminal lines dark rusty red; terminal area and fringe light bluish grey; orbicular stigma tiny, dark brown; discal stigma very narrow, dark rusty red, lunular. Hindwing: ground-colour light brownish grey, with some reddish shade; markings present between tomus and vein M2, postmedial line straight, dark rusty red, bordered by concolorous trapezoidal fields; termen and fringe light bluish grey, with zig­ zagging dark grey terminal line. Underside of wings brown with whitish fragmented transverse lines. The sexes are similar in pattern and size (males: wingspan 31.5-38 mm, length of fore­ wing 15.5-19 mm) but cilia and setae of antenna are shorter in female than in male. On the wings the black markings of male (Fig. 3) are replaced by dark rusty red in female. Genitalia (Fig. 7): Apophyses short, like in most Hadennia species. Sternum A8 bilobed; sinus broad and deep. Sterigma a smooth, transverse narrow trapezoidal plate. Ductus bursae moderately long and broad. Corpus bursae small, globular, densely covered with tiny grains, mid third section bordered by narrow, transverse, sparsely scobinate bands. A small, narrow cervix at posterior third of corpus bursae. Fig. 1: Hadennia kimae HOLLOWAY, 2008 imago, female (Sumatra, Prapat, HW 3; TB1125f).

Fig. 3: Hadennia kimae Holloway, 2008 imago, male (Sumatra, Aek Tarum, Gunung Malayu); scale bars to Figs. 1-3: 10 mm (Figs. 1-3 are to scale). Fig. 4: labial palps of Hadennia kimae HOLLOWAY, 2008 female; Fig. 5: labial palps of Hadennia kimae HOLLOWAY, 2008 male; scale bars to Figs. 4-5: 5 mm (Figs. 4 and 5 are to scale). Appendix present: smooth, arising from anterior tip of corpus bursae, built by a broad tubular and a narrow, ovoid sac-like part. The ductus bursae and the corpus bursae match well in shape to the aedeagus and the vesica, respectively. In addition, the comuti can be encompassed by the ap­ pendix. Diagnosis The female genitalia are similar in overall structure and proportion to those of H. subapicibrunnea HOLLOWAY, 1976 but the corpus bursae is scobinate and bears an appendix, while in the latter species the whole bursa is smooth and lacks the appendix. Hadennia incompleta (PROUT, 1928) has an ovoid appendix at the anterior tip of corpus bursae, moreover, its corpus bursae is partially densely scobinate; although the very broad ductus bursae and the lack of the tubular part of the appendix are dissimilar to H. kimae. Distribution Borneo, Sumatra (new for this area), Singapore (LEONG 2009), Thailand (KONONENKO & PlNRATANA 2013). Fig. 6: first and last abdominal segments of Hadennia kimae HOLLOWAY, 2008 (TB1125f).

Comments Several specimens were collected at 1050 m above sea level in Sumatra, this altitude is colonised by submontane rainforest according to RHIND (2010). Thus, the upper limit of altitude and the habitat spectrum of the species are extended. Considering the male genitalia HOLLOWAY (2008) states that the vesica holds two comuti with unequal length. It is worth to note that a Sumatran specimen figured here (Fig. 8) has equally long comuti while the comuti of another specimen have unequal length. Holloway’s figure shows rounded or rather truncate tips of comuti, while those of the Sumatran specimens are very pointed. Apparently the comuti of Holloway's slide are damaged.
