REMARKS
This genus is tentatively regarded as distinct from Baguoidea (see Remarks under that genus). It differs only in having the basal group setae of the subgenital plate not blunt-tipped and in having an unusual ventral apodeme of the 8th abdominal sternite with a pair of short anterior lobes ( Fig. 4F View FIG ), and also found here with a series of short setae at the posterior lateral corner of the 8 th sternite. There is considerable variation among species in proportion of the vertex, size and colour, for example, in Dayus formosus the vertex is distinctly longer medially than next to eye but more or less the same in D. trifurcatus Yu & Yang, 2013 while the latter is yellow and not red as in some other congeners and very much bigger (two paratypes of D. trifurcatus [♂ and ♀] examined, NHM). A key to the Chinese species of the genus was given by Yu & Yang (2013). CHECKLIST AND DISTRIBUTION OF DAYUS SPECIES
