KEY TO ANTHEROMORPHA SPECIES FROM VIETNAM

1. Lobules of gonopod tip as long as a half of solenophore length ( Figs. 1 , 3 ) ...............................................................................2

− Lobules of gonopod tip shorter than a half of solenophore length ( Figs. 5 , 8 , 9 ) ...............................................................3

2. Body colour red or red-brown, two paramedian red longitudinal stripes on metaterga ( Fig. 2 ); sternum 5 th with two independent, sparsely setose, highly elevated tubercles between coxae 4 ( Fig. 2H ); epiproct with two straight, small, lateroapical tubercles ( Fig. 2I )....................................................................... A. festiva

− Body colour not red or red-brown, metaterga delicately rugose, without two paramedian red longitudinal stripes; sternum 5 with a high, medially emarginated, sparsely setose lobe between coxae 4; epiproct with two, claw-shaped, small, lateroapical tubercles (see Likhitrakarn el al., 2016: p.50, fig. 19)............. ................................................................................ A. harpaga

3. Body red or brownish red ( Figs. 6 , 7 ). Gonopod tip strongly divided into two processes, one being lanceolate, the other being serrated apically ( Figs. 8 , 9 ) .................... A. pumatensis

− Body black or brown-blackish. Gonopod tip strongly split into two subequal, lanceolate processes ( Fig. 5 ).............. A. paviei
