Key to the Alluviobolus species:

1 Male coxae 3–7 with processes ( Figs 44B , 45B). Telopodite of posterior gonopods with a sclerite of elongated triangular shape (x in Figs 44H , 45I). Body with 47–49 body rings...................................................................... 2

– Male coxal processes absent ( Fig. 47B ). Telopodite of posterior gonopods with a sclerite of wide rectangular shape (x in Fig. 47G ). Body with 42–44 body rings........................................................................ A. antanosy sp. n.

2 Colour on mesozonites grey, metazonites black, dorsally with a wide red stripe. Male coxae 3 and 4 with slender processes ( Fig. 44B ). Telopodite of posterior gonopod without a lateral membranous fringe ( Fig. 44H )............. ..................................................................................... A. laticlavius sp. n.

– Colour on mesozonites dark green, metazonites red, dorsally on mesozonites with a slender orange stripe ( Fig. 42A ). Male coxae 3–5 with a large, swollen process ( Figs 45B , 46B ). Telopodite of posterior gonopod laterally with a membranous fringe ( Figs 45I , 46L )................................. A. tsimelahy sp. n.
