Key to species of Pygoluciola  using males

Modified and expanded from Ballantyne (2008)

1. Median posterior margin of V7 and T8 prolonged and often curving, V7 dorsally and T8 ventrally and partially engulfing each other............................................................................................... 2

- Median posterior margin of V7 and T8 not prolonged; if V7 prolonged then not curving strongly dorsally and not engulfed by T8; posterior margin of T 8 may be slightly downturned but not narrowed........................................ 7

2. All tibiae curved; lateral margins of elytra tapering posteriorly ( Ballantyne & Lambkin, 2006, fig. 6)................... 3

- No tibiae curved; lateral margins of elytra usually sub-parallel-sided............................................. 4

3. Apex of median posterior projection of tergite 8 no wider than rest and rounded, not emarginate; lateral margins of pronotum slightly sinuate ( Ballantyne & Lambkin, 2006 figs 1, 19, 21).................................. guigliae (Ballantyne) 

- Apex of median posterior projection of tergite 8 wider than rest; median emarginate; lateral margins of pronotum not slightly sinuate ( Ballantyne & Lambkin, 2006 figs 4, 25)................................................. stylifer Wittmer 

4. Median posterior projection of abdominal V 7 bifurcate at apex ( Ballantyne & Lambkin, 2006 figs 18, 26).............. 5

- Median posterior projection of abdominal V 7 not bifurcate at apex.............................................. 6

5 Apex of median posterior projection of abdominal V 7 deeply emarginate, laterally ensheathing the downturned apex of tergite 8 and projecting laterally beside it ( Ballantyne & Lambkin, 2006 figs 18, 26; Chey 2008 fig 2)........ wittmeri (Ballantyne)

- Apex of median posterior projection of abdominal V 7 shallowly emarginate, not laterally ensheathing the downturned apex of tergite 8 and not projecting beside it ( Ballantyne & Lambkin, 2001 figs 5, 10)................... kinabalua (Ballantyne) 

6 MPP of V7 elongate slender, ventral surface shallowly depressed along its length, and bearing on its median dorsal surface two slender teeth; posterior apex of MPP not differentiated; lateral margins of T8 downturned................ satoi Ballantyne 

- MPP of V7 shorter, about as wide as long, ventral surface not shallowly depressed along its length, and not bearing dorsal teeth; posterior apex (face) of MPP differentiated and shallowly depressed; lateral margins T 8 not downturned................................................................................................. hamulata (Olivier)

7. MPP of V7 defined, longer than wide and either horizontal or inclined slightly upwards along its length and grooved along its ventral surface (Figs 3, 6, 10, 12, 14); T8 much narrower than preceding tergite and apically pointed ( Fig. 15 View Figure )............................................ ………………………………………………………………….. dunguna Nada  sp. nov.

- MPP not defined, posterior margin of V7 rounded; T8 not much narrower than preceding tergite and not apically pointed.. 8

8. Australian species; pronotum with wide median black band reaching to anterior and posterior margins; eyes large, subcontiguous ventrally, with well defined posterolateral eye emargination; elytra brown with pale lateral margins.. cowleyi (Blackburn) 

- Chinese species; pronotum pale whitish cream with restricted median brown spots; eyes not subcontiguous ventrally nor with well defined eye emargination; elytra black............................................... qingyu Fu et Ballantyne
