Wells, Alice, 2010, Australian species of the genus Agapetus (Trichoptera: Glossosomatidae), with descriptions of 13 new species, Zootaxa 2420, pp. 1-25 : 11

Agapetus sheldoni sp. nov.

Figs 12 a, 12b, 35

Material examined: Holotype male: Queensland: 18°57’S 146°10’E, Mt Spec State Forest, Birthday Creek above weir, 6.xii.1993, A.L. Sheldon, NMV.

Diagnosis: Males of this species are distinctive in the Australian fauna in having the gonopods obliquely truncate in ventral view. In this respect they closely resemble the New Guinean A. ulmeri Ross ; they differ from that species, however, in lacking the basoventral expansion on the gonopods, and having the cerci more triangular in shape when seen in lateral view.

Forewing length: Male 3.0 mm.

Male genitalia: Abdominal sternite VI mesal process elongate, curved caudad. In lateral view, abdominal segment IX shallowly triangular anterolaterally. Segment X membranous, rounded. Cerci short, sharply triangular. Gonopods in ventral view stout basally, concave mesally, apex obliquely truncate and without teeth or spurs, in lateral view stout, rounded apically. Phallic apparatus with 2 slender parameres, aedeagus apex swollen, surface sculpted.

Female. A single female collected with the holotype may be referrable to this species; it resembles that of A. cralus , showing no distinctive features.

Etymology. Named for Tony Sheldon who collected numerous Trichoptera when working on macroinvertebrates of streams on Mt. Spec.

Distribution. Known only from the type locality in the wet tropics of northeastern Queensland.
