Agapetus dayi Ross

Figs 4 a, 4b, 26

Agapetus (Synagapetus) dayi Ross, 1956: 162 .

Material examined: Holotype male: New South Wales: Bathurst, BMNH [originally a paratype of A. pontona ]; 71 samples from eastern Victoria and 7 from southern New South Wales, NMV; 3 samples from northern Victoria, ANIC.

Diagnosis: Males are distinguished from those of the similar A. pontona , with which A. dayi was confused initially, by having gonopods with the distal ventromesal margin sclerotised and bearing a 2nd black tooth medially; the cerci are parallel-sided and rounded apically, not club-shaped as in A. cralus , and less so in A. laparus and A. pontona . In ventral view A. dayi closely resembles A. monticolus , but A. dayi is readily distinguished by the narrow cerci and the absence of any sclerotisation on segment X. The phallic apparatus of Agapetus dayi includes a pair of parameres that are constricted medially, striated distally. Females exhibit no particularly distinctive features.

Forewing length: Male 2.8–3.9 mm; female 4.4–5.1 mm.

Distribution: This is one of the most commonly collected species in central and eastern Victoria, and found as far north as the Coonabarabran area and Bellinger River of northeastern New South Wales.
