Taxonavigation

Ordo: Coleoptera
Familia: Cantharidae
Genus: Themus

Name

Themus crassimargo Champion, 1926 – Wikispecies link – Pensoft Profile

Type material examined

1♂ (BMNH, lectotype of Themus crassimargo), [p]“Gopaldhara, Sikkim, vii.1924, H. Stevens”, [p] “LECTOTYPUS”, [p] “Themus \ crassimargo \ Champ.”. The lectotype was designated by Wittmer (1975)[1].
1♂ (NHMB, holotype of Themus (Telephorops) subcaeruleiformis), [h] “Kuanshien (Guanxian, now is Dujiangyan) \ Umg. VIII.1934”, “600–1300m \ Szechwan (Sichuan), China”, [p] “HOLOTYPUS”, [h] “T. (Telephorops) subcaerulei- \ formis Wittm. \ det. W. Wittmer”, [p] “Naturhist. \ Museum Basel \ coll. W. Wittmer”, [p] “CANTHARIDAE \ CANTH00001233”.

Other material examined

CHINA, Xizang: 1♂ (CAUB), Zayü, Shajiong, 1700 m, 1978.VI.26, leg. F.S. Li. Sichuan: 1♀ (IZAS), 70 km West Chengdu, Qingcheng, Hou Shan mts., 1360 m, 30°44'N, 103°08'E, 2004.VIII.28, S. Murzin.

Distribution

China (Xizang, Sichuan), N. India, Bhutan, Nepal.

Supplementary description

Female (Fig. 3B). Like male, but antennomeres V–XI without impressions along outer edges (while present with smooth narrow longitudinal or oblong impressions in male), terminal abdominal ventrite wide (while narrow and triangular in male) (Fig. 9D) with posterior edge triangularly protuberant on each side, space between lateral protuberances about twice as wide as each width.

Remarks

Themus (T.) subcaeruleiformis Wittmer, 1983 was originally described based on a single male type, from China, Szechwan, Kuanshien Umg. (now in Sichuan, Dujiangyan). Here a female (Fig. 3B) collected from Qingcheng, which is near the type locality, is discovered for the first time. The structure of its abdominal sternite VIII (Fig. 9D) is like that of T. crassimargo Champion, 1926, illustrated by Okushima (1999[2]: fig. 35). Furthermore, T. subcaeruleiformis was only compared with T. subcaeruleus located in Yunnan, China in the original publication (Wittmer 1983b[3]), but not with species from the Himalayas (Wittmer 1975[1]).Moreover, the types of T. subcaeruleiformis and T. crassimargo were compared, but no differences between them were found in external morphology (Fig. 4A, B) and aedeagi illustrated by Wittmer (1975[1]: fig. 2; 1983b: fig. 3, 3a).Therefore, T. subcaeruleiformis is proposed here to be junior synonym of T. crassimargo, according to the Principle of Priority (ICZN 1999[4], Article 23.1).
