Key to species of Prolactistes

1 Paraclypeus with a row of setigerous punctures including 10–11 peg-like setae; ocular index 3.20–3.40; ocellar index 4.4–4.8; pronotum about 1.6 times as broad as long; paramere as in Figs 8 and 11 ; second conjunctival appendage of the aedeagus strongly recurved apically as in Fig. 14 . ... P. jani (J. A. Lis, 1995)

– Paraclypeus with a row of setigerous punctures including only 6–9 peg-like setae; ocular index 2.70–3.10; ocellar index 3.0–4.5; pronotum about 1.8 times as broad as long; paramere not as in Figs 8 nor 11; second conjunctival appendage of the aedeagus apically slightly recurved or almost rectangular ( Figs 15–16 ). ........ 2

2 Paramere as in Figs 9 and 12 ; second conjunctival appendage of the aedeagus apically slightly recurved ( Fig. 15 ); opening of the male genital capsule with elongat- ed sharpened tooth at each side of the inner margin ( Fig. 17 ); proctiger straight on its apical margin ( Fig. 19 ); spermathecal seminal receptacle rounded ( Figs 21–22 ). .................................. P. australis J. A. Lis, 2001

– Paramere as in Figs 10 and 13 ; second conjunctival appendage of the aedeagus apically almost rectangular ( Fig. 16 ); opening of the male genital capsule with a small rounded tooth at each side of the inner margin ( Fig. 18 ); proctiger slightly incised on its apical margin ( Fig. 20 ); spermathecal seminal receptacle elongated ( Figs 23–24 ). .............................. P. lisi ( Magnien, 2014)
