Polyplectropus lascusalbinae (originally lacus-albinae) Kimmins in Mosely & Kimmins, 1953: 363, fig. 249. Neboiss, 2002: 67.

Holotype male: NSW, Mt Kosciusko , Lake Albina, 6350 ft, 28 Jan 1930, R.J. Tillyard ( ANIC) (Type not found).

New material examined: Australia: Australian Capital Territory: 1 male, Wombat Ck , 6 km NE of Picadilly Circus, 750m, 35°19'S, 148°51'E, Apr 1984, T. Weir & J. Lawrence ( ANIC) . New South Wales: 1 male (CT-848, figured specimen), Kosciuszko NP, 0.8 km NE Thredbo , 1480m, 36°29'49"S, 148°18'51"E, Malaise, 2–11 Jan 2004, C.L. Lambkin & N.T. Starick ( ANIC) . Victoria: 1 male (CT-915), Pioneer Ck , mid site, 37.89890°S, 145.79206°E, light trap, 11 Jan 2022, J. Lancaster & B. Downes ( NMV TRI-57117 ) ; 2 males (& 1 female), Pioneer Ck , up site, 37.90255°S, 145.76997°E, light trap, 11–12 Jan 2022, J. Lancaster & B. Downes ( NMV TRI-57114 /57115) ; 1 male, Tarago R., mid site, 37.94053°S, 145.81497°E, light trap, 11 Jan 2022, J. Lancaster & B. Downes ( NMV TRI-57116 ) ; 1 male, Wilsons Promontory, McAlister Ck bridge, Telegraph Track , -39.0483, 146.3656, 6 Nov 2024, J. Finn ( NMV JKF _2024_EPT#38). Other records (see Neboiss, 2002) .

Diagnosis. This is the only Australian species of Polyplectropus which has genitalia with an elongate dorsolateral process on the preanal appendages, combined with inferior appendages which in lateral view appear robust, rounded.

Remarks. Polyplectropus lacusalbinae is a distinctive species, originally described from a single male from Lake Albina, Mt Kosciusko, New South Wales. Neboiss (2002) recorded the species more widely with records of a male from each of Noojee, Victoria, and Flinders Island, Tasmania. It seems to be uncommon but with a disjointed distribution in SE Australia. Polyplectropus lacusalbinae is likely more widespread in Tasmania ( Neboiss 2002).

Distribution. Recorded from Victoria, New South Wales ( Neboiss 2002), ACT, and Tasmania (a single male, PT-1694, from Flinders Island), (latitudinal Range 35.3– 40.1°S).
