Taxonomic notes

Medium size species (10.2 mm) with a slender abdomen; the two facial, lateral, shiny stripes are wider than those in the similar Q. subcostalis , which also differs from Q. sylvicola by the presence of golden yellow hairs on the face (whitish in Q. sylvicola ); Q. sylvicola can be separated from females of the similar Q. picadoi and Q. calathea by the extensively microtrichose alula.
