 Taxonomic notes   
 Large species (13.4 mm) with broad abdomen; similar to Q. inbio sp. nov., Q. salvadorensis sp. nov., and Q. tica sp. nov., although males of these species can be readily separated from Q. vicentinae sp. nov. by the shape of the superior lobes and surstyli of the genitalia (Figs 40–42, 58, 59, 62–64, 67, 68); otherwise, Q. vicentinae sp. nov. can be separated from Q. inbiosp. nov. and Q. tica sp. nov. by the presence of a conspicuous group of golden yellow hairs on the PC, whereas these hairs are mainly black in Q. inbio sp. nov. and Q. tica sp. nov.
