Reboleira, Ana Sofia P. S. & Enghoff, Henrik, 2013, The genus Boreviulisoma Brolemann, 1928 — an Iberian-N African outlier of a mainly tropical tribe of millipedes (Diplopoda: Polydesmida: Paradoxosomatidae), Zootaxa 3646 (5), pp. 516-528 : 525-526

Identification of Boreviulisoma species

Differences between the three known species of Boreviulisoma are summarized in Table 1 and in the following key:

1. Metazonal setae short, clavate......................................................... B. liouvillei ( Morocco)

- Metazonal setae long, pointed.......................................................................... 2

2. Depigmented. Male legs 5–7 and 9–10 with femoral knobs........................... B. barrocalense n. sp. ( Portugal)

- Reddish-brown. Male legs from 3 to ca. 26 with femoral knobs................................... B. badium ( Spain)

B. liouvillei B. badium B. barrocalense n. sp.

Tip of gonopod with a small pointed projection rounded (Figs 18–19) with small bifid projection + ( Figs 24–26 ) hawksbill-like dorsal projection (Figs 10–14)

Data in parentheses on B. liouvillei from Brolemann (1928) and Schubart (1960), data on B. badium from Attems (1952).
