Acinolaemus Thompson & Upatham, 1997: 223, 224. Schileyko 1998: 255. Panha and Burch 2005: 39. Vermeulen et al. 2007: 86.

Type species.

Acinolaemus ptychochilus Thompson & Upatham, 1997, by original designation.

Remarks.

The genus currently contains 11 species (MolluscaBase 2025) with few to many apertural dentitions, a shell with ascending to descending tuba or without tuba, and a shell surface with rectangular reticulations to prominent spiral striations (Table 4; Thompson and Upatham 1997). These variations are possibly the cause that rendered the generic boundary ambiguous and necessitates intensive systematic revision.
