Introduction
The beetle family Dermestidae (Coleoptera) currently includes about 1750 species and subspecies worldwide (Háva, 2015a, 2021). During the determination of Dermestidae from author´s collection, I found five new species from Laos, Malaysia and Indonesia which are described below; additionally, six species are newly recorded from Malaysia, Indonesia, China and India.
Material and methods
The species are listed in the alphabetical order, the nomenclature and zoogeography follow the catalogue of Háva (2015a).
The following abbreviations of measurements were used (in mm):
Total length (TL) - linear distance from anterior margin of pronotum to apex of elytra.
Elytral width (EW) - maximum linear transverse distance.
Mentioned material deposited in the following collections:
JHAC - Jiří Háva, Private Entomological Laboratory & Collection, Únětice u Prahy, Prague-West, Czech Republic;
NMPC - National Museum, Praha, Czech Republic;
NMWC - Natural Sciences National Museum Wales, Cardiff, United Kingdom.
Specimens of the presently described species are provided with red, printed labels with the text as follows: “HOLOTYPE [or PARATYPE, respectively] species name sp. nov. Jiří Háva det. 2021.”

Thaumaglossa sp.: Háva, 2015b: 16.
Description. Female: Body measurements (TL 3.4, EW 2.4), strongly convex, ovate, widest at humeri, pronotum dark brown, elytra black, antennae brown, legs brown; body covered with white and yellow setation. Head black covered with yellow setation, finely punctate. Antennae with 11 antennomeres, densely covered with yellow, erect setation (Fig. 4). Antenna occupies the entire cavity of antennal fossa. Frons with median ocellus. Pronotum dark brown, densely punctate, covered with short, yellow and white setation; yellow setation forming large area discally. Elytra black, coarsely punctate on humeri and on basal half, other parts densely punctate, covered with short, white setation. The white setation leaving small, circular spots. Epipleuron black with white setation. Scutellum triangular, shiny, visible, without setation. Prosternum intensely punctate on disc, without impunctate median line, covered with white setation. Mesosternal disc with large punctures, covered with white setation. Visible abdominal ventrites brown with white setation. Pygidium brown, with yellow setation.
Male. Unknown.
Differential diagnosis. The new species belongs to the T. rufocapillata species group, and is very similar to Thaumaglossa haucki Háva, 2015 but new species differs from it by the bicolorous setation on the pronotum (haucki- pronotum covered by only grey setation) and structure of terminal antennomere.
Type material. Holotype (♀): „Malaysia W, Perak 25 km NE of Ipoh, 2100 m, Banjaran Titi Wanga Mts., Korbu Mt., 4-13.iii.1998, P. Pacholátko lgt., (JHAC). Paratype: (1 ♀): “Malaysia W, Kelantan, Kg. Tunku, 1200 m, 150 km S of Jeli, 21ii.-14.iii.2013, P. Čechovský lgt.”, (JHAC).
