After thorough examination of the
holotype
preserved in AM, I am now able (see Munari, 2002) to confirm the validity of this species and dispel any doubt about a possible (see
Malloch, 1935
) conspecificity with
Dasyrhicnoessa serratula
Malloch.
Dasyrhicnoessa fulvescens
is chiefly characterized by the following combination of characters: body and legs entirely pale to fulvous yellow, except for syntergite 1+2 and tergite 3 broadly blackened (I do not know whether this colour is of pigmental nature or due to
postmortem
factors affecting the internal organs); all setae and setulae golden brownish or golden yellow; arista micropubescent; fore femur lacking true ctenidium, but with 3–4 microscopic, thin hairs present at its place; 4 rather regular rows of acrostichal setulae on anterior half of scutum (thus, not “irregularly sexseriate” as erroneously stated by
Malloch [1935]
); both proepimeral and proepisternal setae present. No other species of
Dasyrhicnoessa
share these features.
