. Length is between 1.40–2.10 mm. The carapace narrows anteriorly, so that the maximum height is in the posterior half and is slightly greater than half the length or subequal to the length. The postero-dorsal corner of the carapace is distinct, but the posterior margin and the postero-ventral corner are strongly rounded. The right asymmetrical gland is located centrally on the posterior ventral curve of the carapace. The left asymmetrical gland is shifted anteriorly along the dorsal margin opening about 10–20% from the posterodorsal corner through a bump clearly projecting above the dorsal margin. Sculpture is obscure.
