Key to species of the Lepanus nitidus species group

1 Ridge on ventral side of protibia apically more or less joined to the second tooth by a fine carina (Fig. 13G); aedeagus with left paramere excised apically............................................................................... 2

– Ridge on ventral side of protibia not joined to the second tooth by a fine carina (Fig. 13H); aedeagus with left paramere excised apically or not........................................................................................ 3

2 Lateral lobe of metaventrite with inner border beside mesocoxa anteriorly widened (Fig. 13M); male medial lobe of metaventrite with a very small tubercle located approximately halfway between mesocoxae and metacoxae (Fig. 13I); male protibia as in Fig. 13A; aedeagus as in Fig. 16D; generally larger species 3.6–4.4 mm; widely distributed in Queensland Wet Tropics from south of Cooktown to Cardwell Range.......................................... Lepanus nitidus Matthews, 1974

– Lateral lobe of metaventrite with inner border beside mesocoxa not anteriorly widened, of same width throughout (Fig. 13N); male medial lobe of metaventrite without very small tubercle; male protibia as in Fig. 13C; aedeagus as in Fig. 16C; smaller species 3.5 mm; Queensland northern Wet Tropics, apparently restricted to the Mt Finnigan and Thornton Peak blocks above 700 m. .......................................................... Lepanus kulki Gunter & Weir, new species

3 Apical area of elytra nitid, with stria 1 and usually stria 2 superficial, appearing as a single line (Fig. 13L); metaventrite smooth and nitid between metacoxae, male with a very small tubercle located closer to metacoxae than mesocoxae (Fig. 13J), female without tubercle or depression; male protibia as in Fig. 13D; aedeagus as in Fig. 16B, with left paramere excised apically; 3.3–3.8 mm; Queensland Wet Tropics from Lamb Range to Ravenshoe.................. Lepanus dichrous (Gillet, 1925)

– Apical area of elytra usually very finely reticulate, with stria 1 and usually stria 2 slightly impressed, appearing as a double line (Fig. 13O); metaventrite between metacoxae more-or-less reticulate, male with a medial longitudinal depression between mesocoxae and metacoxae (Fig. 13K), female with a small depression and medial line between metacoxae; aedeagus as in Figs. 16A, E with left paramere not excised apically, somewhat pointed; larger species 4.0– 5.2 mm ......................... 4

4 Metaventrite with punctures on medial lobe minute, much smaller than those on the lateral lobe (Fig. 13P); male protibia as in Fig. 13E; pygidial reticulation usually confined to central and basal areas; aedeagus as in Fig. 16E, with apically deflexed part of right paramere rounded; Queensland Wet Tropics from Lamb Range to Cardstone, above 750 m. ................................................................................ Lepanus vangerweni Gunter & Weir, new species

– Metaventrite with punctures on medial lobe larger, about the same size as those on the lateral lobe (Fig. 13Q); male protibiae as in Fig.13F; pygidium usually nearly completely reticulate; aedeagus as in Fig. 16A with apically deflexed part of right paramere angulate; Queensland Wet Tropics, apparently restricted to the Mt Carbine Tableland Zone. ......................................................................................
