Figs 6 View FIGURES 4 – 6 a, 6b, 29

Material examined: Holotype male: Victoria: Aire River, 4 km NE Glenaire, 4.xii.1972, NMV.

Paratypes: Victoria: Same data as for holotype, 2 males 1 female, NMV; Stevensons Falls, Upper Gellibrand River, 20.i.1982, A. Neboiss, 2 males, NMV [Tri-1044].

Diagnosis: The male of Agapetus paracralus is similar to those of A. paluma sp. nov., A. cralus , and A. pontona , but is distinguished by having the gonopods in ventral view narrower and each bearing 2 prominent black teeth, situated one behind the other rather than at about the same distance from the apex as in A. tabrabucca (see above).

Forewing length: Males 3.8–4.2 mm; females 4.1 mm.

Male genitalia: Sternite VI ventral process present, in lateral view elongate, straight and sharply pointed. Abdominal segment IX in lateral view long ventrally, angulate anterolaterally. Segment X in lateral view broadly rounded dorsally, acute posterolaterally. Cerci in lateral view subrectangular. Gonopods in ventral view narrow in distal 2/3rds and with pair of small rounded black teeth subapically; in lateral view stout, length about 3 times width, broadly rounded apically. Phallic apparatus elongate, bearing terminal, membranous, striated parameres with pre-constriction section about 3 times as long as spines.

Female: Terminalia in dorsal and ventral view very narrow, abdominal segment VIII deeply excised midventrally.

Etymology: Name descriptive of its superficial similarity to A. cralus .

Distribution: Known only from the Otway Ranges in southwestern Victoria.
