The holotype and paratype are deposited at the Laboratory of Animal Systematics , Yeungnam University , Gyeongsan , South Korea . Etymology The species name is from the Latin opacus (dark), in reference to the dark shaded colour of the body. Differential diagnosis Balcha opaca is included in the laciniosa species group as defined by Gibson (2005) because it has a thick, asetose dorsellum with a short dorsal crenulate band at an abrupt angle to a more vertical posterior coriaceous surface, and the paraspiracular region bare except for about seven setae in the female and three setae in the male anterior to the level of the spiracle. This group consisted of B. lacinosa Gibson as well as B. camptogastra Gibson , B. enoptra Gibson , B. reticulata Nikol ’ skaya, and B. splendida (Girault) . The female of B. opaca differs from those of B. enoptra and B. camptogastra in having an unmodified syntergum, from B. splendida in its mesoscutal colour pattern [without a psi-shaped (Ψ) dark region], and in the presence of lanceolate setae on mesoscutum, and from B. laciniosa in having only inconspicuous hairlike setae posterodorsally on the mesoscutum (in B. laciniosa such setae are interspersed with obvious, lanceolate setae) and also in sculpture of the scutellum, which in B. laciniosa is reticulate posteriorly but anteriorly has longitudinal furrows separated by ridgelike interstices ( Gibson 2005 ). Remarks The above diagnosis and etymology are re-published from Fusu et al . (2018) with permission in order to conform with Art. 13.1.1 of the code (ICZN 1999) that states that in order to be available a new name must be accompanied by a “… description or definition that states in words characters that are purported to differentiate the taxon …” . A mere reference to the description of the species in Fusu et al . 2018 that would validate the new name under Art. 13.1.2 would not be enough because for the purposes of nomenclature, Fusu et al . (2018) does not exist, and therefore no part of it can be used to make a name available.
