Loxiodamediofascia Swinhoe
Rhesala mediofascia Swinhoe, 1902, Ann. Mag. nat. Hist. (7), 9: 424.



. The ground colour is as in other Loxioda, but the postmedial fascia is stronger, and its equivalent on the hindwing is displaced basad to a more medial position rather than being a similar distance from the margin as that on the forewing. The forewing reniform consists of two dark dots set transversely rather than just a single one.

Taxonomic note. Phragma lobes on the second abdominal tergite are strong rather than reduced. The male genitalia are as atypical as the facies of this species, having a short, bulbous uncus, a very elongate tegumen and vinculum (the latter with a long, slender saccus and a serrate dorsal part on each side), and broadly ovate valves with a central spur. The eighth segment is of the framed corematous type. The female genitalia have a robust, partially sclerotised ductus bursae and an ovate corpus bursae from which the ductus seminalis arises basally, and the basal two thirds is strongly spined with short, stellate spines. The facies is similar to that of “Blasticorhinushampsoni Bethune-Baker (New Guinea) and “Maxeraarizanensis Wileman (Taiwan). Both are probably misplaced in their genera, and only arizanensis is potentially a close relation of mediofascia, sharing some general features of the male abdomen, particularly in the shape and ornamentation of the valve in the genitalia.

Geographical range. Borneo.

Habitat preference. A single specimen has been taken during recent surveys in disturbed coastal vegetation at Mumong in Brunei. Older material is from Kuching in Sarawak and from the vicinity of Pontianak in Kalimantan. The holotype is from Sarawak without more precise data.
