Key to larvae of the genus Lebertia

1 P-4 stout, longer than high ( Fig. 5 ), excretory pore plate rhomboidal in shape ( Fig. 3 ), III-Leg-3 with two heavy setae ( Fig. 8 ), III-Leg-5 with acanthoid seta........................................................ L. insignis Neuman, 1880

- P-4 more slender, shorter than high, excretory pore oval or nearly circular in shape, III-Leg-3 with one single heavy seta, III- Leg-5 without acanthoid seta............................................................................ 2

2 Urstigma small (D 9–11 µm), I–III-Leg–5 long (78–90, 89–106, 102–128 µm, respectively), P–4 with three subequal setae (two dorsal and one medial, Fig. 32 )..................................................... L. saxonica Thor, 1911

- Urstigma relatively large (D 14–16 µm), I–III-Leg–5 comparatively short (64–74, 74–80, 85–90 µm, respectively), P–4 with three unequal setae (short dorsal and medial, and relatively long ventral, Fig. 18 ).................. L. porosa Thor, 1900
