Bruggennea Dance, 1972: 131.
Bruggennea — Richardson, 1988: 4.
Bruggennea — Schileyko, 2000: 800.
Type species. Sinoennea laidlawi Dance, 1970 by original designation.
Diagnosis. Shell ovoid or conical-ovoid, apertural dentition agree with that of Sinoennea (parietal lamella + columellar lamella, upper palatal tooth situated on peristome, lower palatal tooth situated deeper), varices (remaining expanded peristomes of juvenile shells) are imperfectly arranged in two rows on opposite side of the spire.
Distribution. Endemic to Borneo.
Remarks. The apertural dentition agrees with that of Sinoennea. Based on the original description (Dance, 1972), the distinction from Sinoennea is based on shell shape and sculpture, and the presence of varices. A more recent revision of this genus (Vermeulen, 2007) mentioned only the latter character as a distinctive feature. At the moment it is not possible to say more. Bruggennea is probably monophyletic due to the similar traits and geographic distribution, but the very diverse Sinoennea may not be monophyletic without Bruggennea. See Figs. 3 and 22G for comparison.
