Dasyrhicnoessa fulvescens Malloch, 1935

Mathis & Sasakawa, 1989: 667; Mathis & Munari, 1996: 12.

Distribution. Australia (QLD).

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.
