Type species: Spirobolus rubripes de Saussure & Zehntner, 1897, monotypic

Diagnosis: telopodite process of anterior gonopod slender and laterally curved, a unique character of Zehntnerobolus gen. n. Telopodite of posterior gonopod of unique shape, sperm canal protruding above lateral margin at mid-length (Figs 22E, F). Suspicious row of sclerotized nodules located just below point where sperm canal protrudes above lateral margin (Fig. 22G). Shares a small body size (30–36 mm) and large male coxal processes on coxae 3–5 only with Spiromimus de Saussure & Zehntner, 1901 (Wesener and Enghoff, 2009). Telopodite of anterior gonopod at lateral margin elevat- ed (Fig. 22E), similar to Pseudocentrobolus gen. n. and Granitobolus gen. n. Discharge opening of sperm canal turned laterally (Figs 22E, F), like in Alluviobolus gen. n. and Riotintobolus gen. n.

Distribution and ecology : only known from the East Malagasy rainforests of Andrangoloaka and 30 km SE in Moramanga. Since 1900 no additional specimens have been collected. The reddish-black colour pattern plus medium length antennae and legs might indicate a life on the surface of (or inside) the leaf-litter.

Etymology: Zehntnerobolus, masculine, is composed of Zehntner, after Dr. Leo Zehntner (1864–1961), who described numerous millipede species from Madagascar, including the type species of this genus, and - bolus.
