Key to Australasian genera of Podagrionini and species of Lasallegrion

1 Hind tibia with apex elongately produced, the truncation at least 2x width of tibia and with spur at base of truncation near basitarsus Podagrionella Girault

― Hind tibia with apex diagonally truncated and ventrally not or only slightly produced; the truncation subequal in length to width of tibia and with spur at apex of truncation ...................................................................................................................... 2

2 (1) Mesepimeron bulged outwardly and raised into lamelliform plate above surface of metapleuron and overhanging (partially obscuring) ventral shelf of metepisternum; fore wing with well delimited spot.......................... Propachytomoides Girault

― Mesepimeron not bulged, abutting metepimeron and not overhanging ventral shelf of metepisternum; fore wing without delimited spot, rarely with diffuse stain.................................................................................................................................................... 3

3 (2) Anellus elongate, as long as broad, fore wing entirely covered with setae, without distinct vein tracts, cells or speculum.................................................... Palmon Dalman

― Anellus transverse, fore wing with distinct vein tracts, cells and speculum........ 4

4 (3) Pronotum with a sharp and carinate pronotal collar; antennal clava distinctly 3segmented, females with a narrow line of micropilosity on apical claval segment 2 and 3; metadiscrimen as median strip delimited by irregular submedian ridges......... ................................................................................................................................. Lasallegrion gen n., 5

― Pronotum round and without a carinate collar; antennal clava not distinctly 3segmented, females with a large micropilosity area covering the ventral side of the clava; metadiscrimen broader, with one median or two submedian carinae................................................................................................ Podagrion Spinola

5 (4) Ventral margin of clypeus with small median tooth; metafemur with 6–8, moderately short, teeth plus one composite tooth distally ( Figure 12f View Figure 12 ); ovipositor sheaths short, 0.9–1.5× as long as body; OI = 3.3–5.0; relatively smaller species (2.9–3.7 mm without ovipositor)..................... ..................... L. washingtoni ( Girault, 1915) , comb. n.

― Ventral margin of clypeus hardly convex; metafemur with 5 or 6 stout teeth ventrally plus one composite tooth distally ( Figures 8e View Figure 8 , 11c View Figure 11 ); ovipositor sheaths 1.6–2.5× as long as body; OI = 5.2–7.6; relatively bigger species (3.5–4.4 mm without ovipositor)...................................................................................................................... 6

6 (5) Combined length of pedicel and flagellum 1.45–1.65× breadth of head; head height 0.85–1.02× (in one marginal case up to 1.04) as long as marginal vein; antennae inserted high on the head, distance from lower edge of toruli to ventral margin of clypeus 1.1–1.6× as long as distance from lower edge of toruli to anterior ocellus; parascrobal area remarkably raised above the outline of head anteriorly (best seen from dorsal view, Figure 8a View Figure 8 ); setae on lower face not so dense, long and wide than in alternate ( Figure 8 View Figure 8 b–c); propodeum with adpetiolar area (behind posterior branches of carinae) coarsely rugose ( Figure 6d View Figure 6 ), metafemur with 5 teeth preceding the composite terminal one, at least length of 3 rd and 4 th tooth same as or longer than breadth of tibia opposite to tooth ( Figure 8e View Figure 8 ); costal cell of fore wing with 2 complete rows of setae on the underside ( Figure 8f View Figure 8 );.................................................................. .............................................................................................. L. koebelei ( Crawford, 1912) , comb. n.

― Combined length of pedicel and flagellum 1.1–1.4× breadth of head; head height 1.04–1.13× as long as marginal vein; antennae inserted less high on the head, distance from lower edge of toruli to ventral margin of clypeus 1.0–1.2× as long as distance from lower edge of toruli to anterior ocellus; parascrobal area not so remarkably raised above the outline of head anteriorly ( Figure 11a View Figure 11 ); setae on lower face very dense, long and lanceolate ( Figure 11b View Figure 11 ); propodeum with adpetiolar area rugulose reticulate ( Figure 11e View Figure 11 ); metafemur with 4 stout teeth preceding the composite terminal one; length of 2 nd – 4 th tooth longer than breadth of tibia opposite to tooth ( Figure 11c View Figure 11 ); costal cell of fore wing at most with one incomplete row of setae on the underside ( Figure 11f View Figure 11 )................................ ..................................................................................... L. virescens ( Strand, 1911) , comb. n.
