Brachiolum with 1 seta; R with several setae, R 1 and R 4 + 5 without or with few setae. Squama fringed. Legs. Fore tibia with single comb, with central protruding long spur; mid- and hind tibia with two broadly triangular combs, each with protruding spur. Pseudospurs absent. Pulvilli simple, pad-like, not reaching apex of claws. Hypopygium. Tergite IX with several weak setae, laterosternite with few stronger setae. Anal point in dorsal view subtriangular, tapering to rounded apex, in lateral view with apex hooked ventrad. Phallapodeme well developed. Transverse sternapodeme narrow, arched, with low, rounded oral projections. Superior volsella straight with hoked apex, projecting caudally, with microtrichia and seta medially, apically bare. Inferior volsella ovate, with microtrichia and strong marginal and dorsal setae. Pars ventralis, median volsella and pseudovolsella absent. Gonostylus stout with bluntly rounded apex.	en	Andersen, Trond, Sanz-Laparra, Annui Malla, Giłka, Wojciech (2024): The identity of Psilochironomus Sublette, 1966 (Chironomidae, Chironominae, Pseudochironomini).
