Key to males of Acrobelus

1 Subgenital plates extending well beyond pygofer apex, with numerous fusiform macrosetae ( figures 4 , 8 ).................. 2

– Subgenital plates extending as far posteriorly as pygofer apex, without fusiform macrosetae...................... 3

2 Apex of subgenital plates narrowly rounded ( figures 6–8 ); paraphyses with rami not attaining half the length of aedeagal shaft ( figure 9 )... A. nessimiani sp. nov.

– Apex of subgenital plates expanded ( figures 2–4 ); paraphyses with rami attaining half the length of aedeagal shaft ( figure 5 )........ A. rakitovi sp. nov.

3 Aedeagus with median dorsal processes; gonoduct opening on apical portion of aedeagus; paraphyses exceeding aedeagal apex ( Young, 1968: figure 150f; Mejdalani and Emmrich, 1998: figure 7 )................. 4

– Aedeagus without median dorsal processes; gonoduct opening on basal portion of aedeagus; paraphyses not attaining aedeagal apex ( Young, 1968: figure 149f).............. A. reflexus (Signoret, 1855)

4 Aedeagus with small dorsal and ventral processes near mid-length of shaft; apex of shaft not expanded dorsoventrally; paraphyses rami with asymmetrical short spines ( Young, 1968: figure 150f, j)........ A. ecuadorianus Young, 1968

– Aedeagus with small dorsal processes near mid-length of shaft but without ventral processes; apex of shaft expanded dorsoventrally; paraphyses rami without spines ( Mejdalani and Emmrich, 1998: figures 7, 8 )................ A. colombianus Mejdalani and Emmrich, 1998
