DISTRIBUTION. Only known with precision from Chambok, Kampong Speu Province, Cambodia.

NOTES. The female syntype of A. (C.) villicollis Ohaus, 1914 is characterized by long decumbent whitish hairs transversally organized on the pronotum. Females of A. (C.) villicollis can vary in color from partially deep brown to yellowish, with the head always blackish. OHAUS (1914a) compared it to A. (C.) ungulatus Ohaus, 1914 described from Bangkok ( Thailand), and described A. (C.) villicollis based on a female from Cambodia collected by Vitalis de Salvaza without any other information. However, Vitalis de Salvaza mostly collected in the southeastern part of Cambodia (see map in VITALIS DE SALVAZA, 1919), which corresponds to the locality of our specimens.
