Additional material.

Malaysia (Peninsular): 3♀♀, Pahang, Batu Balai Estate, 18 March 1927, E. Seimund, Ex F.M.S. [Federated Malay States] Museum (NHML); 1♂, 1♀, Negri Sembilan, Gunong Angsi, 2000 –2790’ [feet], April 1918, Ex F.M.S. [Federated Malay States] Museum (NHML).

Thailand: 1♀, Uthai Thani Province [western Thailand], Huay Kha Khaeng Wildlife Sanctuary, 15 º36’ N, 99 º20’ E, 1.xi.1995 [1 November 1995], J. Gazhoul, captured at Dipterocarpus obtusifolius Teijsman & Miquel ( Dipterocarpaceae ), D.B. & M.W. Baker Collection (SEMC); 1♀, 150 n.w. Bangkok, Huay Kha Khaeng, 5.xi.1995 [5 November 1995], J. Ghazoul (NHML).

Diagnosisn.

The female of this species can be recognized by the clypeus lacking a medioapical tubercle, short mandibles (Fig. 45), labrum with an apical fringe of erect setae running along relatively straight apical margin, and the yellow wings (Fig. 44). The male can be recognized by the dense setal patch in forewing medial cell, tergum VI with shallow medioapical concavity on preapical carina, protibia with outer, apical surface not depressed, and genitalia as in figures 32-34.

Remarks.

It should be noted that Meade-Waldo’s (1914) material from "Middle Tenasserim" is not conspecific with his type (B.M. Type Hym.17a2037) for Chalicodoma atratiforme and are actually specimens of Chalicodoma odontophorum . Additionally, despite Cockerell’s (1927) assignment of the subspecies Chalicodoma atratiforme sininsulae (Cockerell) (Type USNM 70455; ♀; Turtle Island [Koh Tao], Gulf of Siam; visum) to Meade-Waldo’s species, his female has nothing whatever to do with Chalicodoma atratiforme and is instead a synonym of Callomegachile (Callomegachile) fulvipenne ( Smith 1879) (syn. n.).
