CommentThe original description was supposed to appear as SADLIER, BAUER & WHITAKER, 2000. However, BAUER & SADLIER’s monograph (2000) was published earlier and therefore has to be considered as original description.

Distribution: see map in SADLIER et al. 2014: 54.

Abundance: Rare. This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024. 
EtymologyNamed after LAtin “humectus”, for moist, alluding to the habitat.
