Amended key to the species of West African Deckeniinae

With this revision an amended key to the species of this genus is now necessary, including to distinguish it from Globonautes .

1a G2TA short stub (G2TA/G2SA = 0.1) (Cumberlidge 1999, fig. 53Z; Table 3); G1TA-G1SA junction not marked by visible sulcus on ventral side (Cumberlidge 1999, fig. 52A) (Cumberlidge 1999, fig. 52AA) .............................. .............................. Globonautes macropus

1b G2TA long, flagellum-like (G1TA/G1SA = 0.4–0.6) (Figure 6 (b,e,h,k); Table 3); G1TAG1SA junction with visible sulcus on ventral, dorsal sides (Figure 6 (a,c,d,f,g,i,j,l)) .... 2

2a Pterygostomial region of carapace branchiostegite with patches of dense short setae; ambulatory legs P2–5 medium length (Cumberlidge 1999, pl. 1) .............. A. gerhildae
