Cerambyx pascoei Thomson, 1857: 122 , pl. 14, fig. 6. Type locality: “Inde” (according to the original description) or “ India or.” (according to the label of the holotype) (see also Remarks below).

Conothorax pascoei : Thomson, 1864: 230 (“ Malasia ”).

Massicus [ pascoei ]: Pascoe, 1867: 319.

Massicus pascoei : Lacordaire, 1868: 260 (“Malasie”); Gemminger, 1872: 2802 (“Archip. ind.”); Gahan, 1906: 129 (“Malay Peninsula”); Aurivillius, 1912: 55 (“ Malacca ”); Heffern, 2013: 10 (“E. India; W Malaysia; SE Asia [probably within the limits of Indochina]”); Kariyanna et al., 2017: 31 (“ India & Malaysia ”).

MATERIAL. Holotype by monotypy, ♀ ( MNHN) ( Figs 5–6 ), “ India or.”, “Ex Musaeo James Thomson”, “444”, “ Conothorax Thoms. s.c.230. (Cône, Thorax.), Massicus Pasc. An. M. n. h. XIX, 319.”, “ Pascoei Thoms. Type, Malas. Ind.?”, “Th. / Type” ( Fig. 4 ); 2♂ (cAM) ( Fig. 1 ), Laos, Houa Phan Prov. , Phou Pane Mt., 20°11 ' N / 104°00 ' E, 2060 m, 06.2017 (local collector); 2♀ (cAM) ( Fig. 2 ), same locality, but taken on 05.2017; 1♀ ( BMNH) ( Fig. 3 ), “Malacca”, “Ex Mus Parry”, “Fry Coll. 1905.100.”, “43 … [illegible further on]”, “NHMUK 013386288” (see Remarks below).

REMARKS. Apparently this species was described from a single female originating from India [ Thomson, 1857: 122: “Patrie: Inde”]. However , in the subsequent Thomson’s work [1864: 230] it was given as from “ Malasia ” without any comments. On one labels of the holotype is indicated “ India or.”, while on the other — “… Malas. Ind.?” .

I have studied two males and two females from northeastern Laos that are very similar to the holotype and that I identify here as M. pascoei . Some specimens from China (Yunnan) and northern Myanmar, known to me only from their photographs belong to this species too .

At the same time, almost all specimens I have revised from Western Malaysia, externally similar to M. pascoei , are actually a new species described below.

Only one female ( Fig. 3 ) from the old collections at the BMNH with the “ Malacca ” label almost certainly belongs to M. pascoei . However, its geographical label is possibly erroneous, and therefore it cannot be considered indisputable evidence of the distribution of M. pascoei in Western Malaysia.

MORPHOLOGICAL NOTES. Body length 52.2–58.8 mm, humeral width 14.5–15.7 mm, thereby the holotype is 57.3 mm and 15.7 mm, respectively.

Judging from some photographs, the body length of this species can reach about 61 mm.

DISTRIBUTION. Eastern India, China (Yunnan), Myanmar, Laos; almost without any doubt, Vietnam and Thailand;?Western Malaysia.
