Type material examined. Haematoloecha rubescens Distant, 1883 . Lectotype (present designation) (3): “ 8/ 3/81 ” [handwritten on the reverse side of the mounting card of the specimen]; “ TYPE \ H.T.” [circle with red frame, printed], “ rubescens \ Dist.” [handwritten], “ Japan \ (Lewis)” [handwritten], “Distant Coll. \ 1911–383” [printed]; mounted on card, intact ( BMNH). Paralectotype (Ƥ): “Kuromatsu \ 15/3/81 ” [handwritten on the reverse side of the mounting card of the specimen]; “ Japan \ (Lewis)” [handwritten]; mounted on card, intact ( BMNH). — Haematoloecha laeta Breddin, 1913 . Lectotype ( Gaedike 1971) (Ƥ): “ Tonkin \ Montes Mauson \ April, Mai 2 -3000’ \ H. Fruhstorfer” [with black frame, printed, with handwritten correction], “ Haematoloecha \ laeta Breddin ” [Breddin’s handwriting], “Coll. \ Breddin” [printed]; “ Typus ” [red square, printed]; “ Lectotypus ” [red square, printed]; “H. Gaedike des. 1969” [printed + handwritten]; pinned, left antennal segments IIIb–IV, right antennal segments III–IV lacking ( DEIC) ( Figs. 62–64 ).

Diagnosis. Recognized within Haematoloecha by the combination of the following characters: red species with black pattern as in Figs. 62–63 , ground colour frequently ochraceous ( Fig. 61 ), femora and tibiae distinctly annulate with black; head short, anteriorly gradually declivous, clypeus not elevated and not of angulate outline in lateral view ( Figs. 41–42 ). The species is rather similar in colour to the ‘red-headed form’ of H. nigrorufa , but it can be readily distinguished, among others, by the different shape of the head and the annulate legs. For facilitating the recognition of the species, photos of the lectotype of H. laeta ( Figs. 62–63 ) and a male from Japan ( Fig. 61 ) are provided, data of the latter: Japan: Tōkyō, Chiyoda-ku, Kōkyo, 18.ix.2002, leg. S. Arai (TUA> HNHM).

Taxonomy. Haematoloecha rubescens was described from Japan based on male and female syntypes ( Distant 1883). Two specimens are deposited in BMNH, one of them (a male) labelled as type, another one (a female) bearing no type label. None of the specimens bear a locality label with the type locality given in the original description (Nagasaki). In spite of this fact, we treat them as specimens belonging to the syntypic material, because both of them are obviously part of G. Lewis’s Japanese collection forming the basis of Distant’s (1883) paper; the female was collected in Kuromatsu, located in Kyūshū Island, not far from Nagasaki. The male is hereby designated as lectotype; the female becomes a paralectotype due to the lectotype designation.

The lectotype of H. laeta ( Figs. 62–64 ), described from Northern Vietnam, was concluded to be conspecific with H. rubescens , therefore the following new synonymy is proposed: Haematoloecha rubescens Distant, 1883 = H. laeta Breddin, 1913 , new synonymy.
