Synagapetus crala Mosely , in Mosely & Kimmins 1953: 500.

Agapetus (Synagapetus) crala (Mosely, in Mosely & Kimmins 1953); Ross 1956: 161. Synagapetus styliferus Jacquemart, 1965: 37 ; Neboiss 1977: 37 (for synonymy).

Material examined: Holotype male: Tasmania: Cradle Mountains BMNH ( Fig. 3 );. 66 samples from Tasmania and 25 from central and eastern Victoria, NMV; 3 samples from Tasmania, ANIC.

Diagnosis: Superficially both sexes are indistinguishable from those of A. laparus save that A. cralus males and females have a caudally directed process medially on sternite VI, absent in A. laparus . Males may be distinguished from A. pontona and A. dayi by the more rounded shape of segment X in lateral view, the gonopods stouter basally in ventral view, more elongate in lateral view; and are clearly distinguished from A. dayi by the cerci which are club-shaped in lateral view. This species is distinguished from the closely similar North Queensland A. paluma sp. nov. by the shape of segment IX which is more deeply produced anteriorly, and by the shape of each gonopod and the apicomesal position of its spur. Females are indistinguishable from those of most other Australian Agapetus species.

Forewing length: Male, 4.0–5.0 mm; female 4.5–5.5 mm ( Neboiss 1986b).

Distribution: Widespread in Tasmania, and collected from several sites in southeastern Victoria.

Remarks: A pharate adult (from a small tributary of Cobungra Creek, Cobungra Hill, Victoria, in the collection of NMV) reared from a larva by J. Dean resembles A. cralus in most respects, but in lateral view the cerci are stout with margins parallel; it may represent another species.
