Roman letters refer to normal setae (e to famulus), Greek letters to solenidia. Single prime (') marks setae on anterior and double prime (") setae on posterior side of the given leg segment. Parentheses refer to a pair of setae.
Material examined. Holotype (female): southern Vietnam, Dong Nai Province, Dong Nai Biosphere Reserve, 11°25' N, 107°25' E, Lagerstroemia forest, nest of Black-and-red Broadbill ( Cymbirhynchus macrorhynchos ), 3.VII.2013, collected by Alexander E. Anichkin and Igor V. Palko. Two paratypes (both females): southern Vietnam, Lam Dong Province, Bi Dup – Nui Ba National Park, 12°11' N, 108°40' E, low-stemmed deciduous forest, soil, 6–7.XII.2013, collected by Alexander E. Anichkin and Sergey G. Ermilov.
Type deposition. The holotype is deposited in the collection of the Zoological Institute of the Russian Academy of Sciences, St. Petersburg, Russia; one paratype is deposited in the collection of the Siberian Zoological Museum, Novosibirsk, Russia; one paratype is deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.
Etymology. The specific name hexasetosus refers to the presence of six setae on each genital plate.
Remarks. Yoshiobodes (Dongnaiobodes) hexasetosus sp. nov. differs from Yoshiobodes (D.) biconcavus sp. nov. by the presence of short, clavate sensilli and the absence of two large concavities in the humeral regions of the notogaster (versus sensilli long, elongate, narrowly spindle-form, concavities well developed).
