1. Pyxidicerina, gen. and sp. undet 1 (Fig. 3A)

Specimens examined. 1 male, W (: wolfranium = tungsten) mine, St. A, alt. 1,672 m, by SWA, 20. viii.; 1 female, SE slope, St. A, alt. 1,287 m, by SWA, 21. viii.

Remarks. The subtribe Pyxidicerina is separated from the other subtribe Bythinnoplectina by having a pair of deep cavities where the maxillary palpi are contracted not on the both lateral sides ( Bythinoplectina), but on the frontal side. It is common in Southeast Asia as shown in Nomura et al. (2010) (15 spp. from Thailand), and Nomura (2019) (3 spp. from Laos).
