Fig. 4C

Stelis (Malanthidium) flavofuscinular Nalinrachatakan & Warrit in Nalinrachatakan et al. 2021b: 172-175, see figs 6, 7. (♂) Holotype and paratype from Phu Chong Na Yoy National Park, Ubon Ratchathani, Thailand (CUNHM).

Material examined.

(2♂). Same specimens as in Nalinrachatakan et al. (2021b). Holotype transferred to NHMUK in April 2023.

Distribution.

Thailand (Ubon Ratchathani: Phu Chong Na Yoy National Park).

Since Stelis is a cleptoparasitic bee, its distribution must be in accordance with its host. Noteworthy, the other known species of the subgenus Stelis Malanthidium , S. macaccensis (Friese, 1914) is known from Malaysia; thus, Malanthidium is the only subgenus of Malanthidium Stelis present in South East Asian region.

Bee host.

Anthidiellum phuchongense Nalinrachatakan & Warrit, 2021.

Floral association.

Unknown.

Remarks.

With only two males known, some differences between both specimens and their biology were mentioned and discussed in Nalinrachatakan et al. (2021b).
