Key to Paratopula species

Key to Paratopula species based on workers. Modified from Xu & Xu (2011).

1

 * Dorsal surfaces of middle and hind tibiae with short stout erect to suberect hairs and short decumbent to appressed pubescence => Paratopula macta
 * Brunei, Malaysia
 * Dorsal surfaces of middle and hind tibiae lacking standing hairs, at most with short decumbent to appressed pubescence => 2

2

 * Propodeal lobes sharply hooked upwards apically, their apices directed vertically => Paratopula ankistra
 * Brunei
 * Propodeal lobes rounded or truncated apically, never hooked upwards => 3

3

 * Anterior 2/3 of postpetiolar sternite truncated ventrally => 4
 * Anterior 2/3 of postpetiolar sternite roundly convex ventrally => 5

4

 * Propodeal lobes about as broad as long. Pronotal humeri angulate in dorsal view => Paratopula demeta
 * Malaysia
 * Propodeal lobes broader than long. Pronotal humeri rounded in dorsal view => Paratopula catocha
 * Indonesia

5

 * In dorsal view, petiolar and postpetiolar nodes roughly rectangular. Hairs on first gastral tergite tapering and acute apically => Paratopula ceylonica
 * China, Taiwan; India, Sri Lanka
 * In dorsal view, petiolar and postpetiolar nodes distinctly narrowed backwards. Hairs on first gastral tergite short and truncated apically => 6

6

 * Frontal carinae indistinct behind frontal lobes. Propodeal lobes angulated apically => Paratopula intermedia
 * India
 * Frontal carinae fine and continuous, about as long as scapes. Propodeal lobes truncated apically => Paratopula zhengi
 * China, Tibet
