Diagnosis. Haematoloecha nigrorubra can be diagnosed by the following combination of characters: pronotum bright red; coriaceous portion of fore wing nearly uniformly red; connexiva red to orange ( Figs. 45 , 60 ), paramere conspicuously thick, with broadly laminate keels ( Figs. 50–55 ).

Distribution and subspecific classification. Specimens of H. nigrorubra were examined by us and recorded in the literature from the Eastern Himalayas (northern part of Laos, Southwest China: Sichuan, Yunnan, Guangxi), as well as from Taiwan, however, no record is known from Southeast China. Specimens from the mainland of Asia and from Taiwan are conspicuously different in colour, but no differences could be found in their morphology, including the external male and female genitalia. Consequently, we do not feel justified to recognize the continental and the Taiwanese population as two different species on morphological basis, but we consider them as representing a single polytypic species having a disjunct East Himalayan–Formosan distribution pattern. The two populations are distinguished at subspecies level.
