Anthidium fraternum Bingham, 1897 (nec. Pérez, 1895): 495, ♀. Type locality: Tenasserim.

Anthidium binghami Friese, 1901: 224, replacement name of Anthidium fraternum Bingham, 1897 .

Manthidium binghami (Friese, 1901): Pasteels, 1969: 43.

Stelis siamensis Friese, 1925, 40, ♂. Type locality: Siam (now Thailand). New Synonym.

Bathanthidium (Manthidium) binghami (Friese, 1901): Rasmussen & Ascher, 2008: 30.

Paraanthidium concavum Wu, 1962: 164, ♂. Holotype: ♂, China, Yunnan, Xishuangbannan, 31.VIII.1957, Guang-Ji HONG, IZCAS. New Synonym.

Trachusa (Paraanthidium) concavum (Wu, 1962): Wu, 2006: 174, ♂ (key), 184, ♂ (redescription), Fig. 100a–e.

Material examined: China, Yunnan: Xishuangbannan, Xiaomenyang (22º06′N, 100º53′E), 1 ♂ (holotype of P. concavum), 31.VIII.1957, leg. Guang-Ji HONG .

Floral association: no record.

General distribution: Sikkim, northeastern India, Burma, Thailand, Laos, China (Yunnan).

Remarks: The distribution of this species and its subgenus were cited erroneously by Michener (2000, 2007) to include Malaysia. The “ Malaysia ” record is based on Pasteels’ (1969) misinterpretation of the locality “ Luang Prabang ” which is the capital of Luang Prabang Province in northern Laos. Thus, subgenus B. ( Manthidium) should be excluded from the fauna of Sundaland.

The holotypes of Anthidium fraternum, Paraanthidium concavum and Stelis siamensis have been studied and found to be synonymous.
