Diplectrona tasmanica Jacquemart, Revised status.

( Figs 18–19 , 42–44)

Diplectrona tasmanica Jacquemart 1965 , 27.

Diemeniluma tasmanica ; Neboiss 2003, 71, figs 22A–22G, changed combination.

Material examined. Holotype ♂, Tasmania, Cradle Mountain , 12.i.1923, A. Tonnoir ( IRSNB) . Tasmania: 1♂,? 1♀, Pencil Pine River , Cradle Mtn Rd, 19.i.1976, A. Wells, ( ANIC) .; 1♂ 10 km SW of Queenstown , 11.ii.1971, A. Neboiss ; 1♂, Lake Tahume, Frenchmans Cap Nat. Pk , 20.i.1988, J. Jackson.

Diagnosis. Closely resembling Diplectrona serrula , males of both having numerous fine spicule-like spines apically on the phallus, and digitiform lobes laterally on tergite X, but distinguished from that species by having the midlateral lobes on segment IX extending beyond the tip of tergite X.

Description. (See Neboiss 2003).

Distribution. Found only in Tasmania, in the NW and northern SW provinces.

Remarks. Neboiss (2003) diagnosed females of Diemeniluma as having ‘sternite VIII entire, not divided ventromesally’; however, since the specimen upon which this was based was not located in the NMV collection, this could not be confirmed. A single female specimen in the ANIC collection is associated tentatively with a male of D. tasmanica and appears to have the sternal plates on segment VIII partially fused ( Fig. 44 ), however, the specimen could be teneral.
