Remarks. This species was described by BUDDE-LUND (1904) as Armadillo tuberosus from Port au Prince, Haiti. It was later included in Reductoniscus by KESSELYAK (1930) and then in Cubaris by ( VAN NAME, 1936). The examination of the specimens from Brazil, certainly belonging to this species, showed that it belongs to Ctenorillo as redefined by SCHMALFUSS & FERRARA (1983), of which the genus Tuberdillo Arcangeli, 1941 , is a junior synonym (see TAITI et al., 1998). In fact, it has the cephalon, pereon, pleon and telson with developed costae and tubercles; the cephalon with the frontal lamina protruding above the vertex; pereon, pleon epimera and telson obliquely bent outward; pereonite 1 with schisma; ventral lobe of pereonite 2 tooth-shaped; epimera of pereonites 2-7 rectangular; telson hour-glass-shaped with basal part with two paramedial tubercles and distal part bent outwards with apex truncate; antenna short and thickset; uropod with tiny exopodite.

To date Ctenorillo included 13 species ( SCHMALFUSS, 2003; CAMPOS-FILHO et al., 2014): C. ausseli ( Dollfus, 1893) , from the Canary Islands; C. bananae ( Van Name, 1920) , from Cameroon, Congo and Angola; C. buddelundi Verhoeff, 1942 , from Uganda and Kenya; C. fagei ( Paulian de FÉlice, 1941), from Ivory Coast; C. ferrarai Campos-Filho, Araujo & Taiti, 2014 from Brazil; C. gabunensis ( Schmalfuss & Ferrara, 1983) , from Gabon; C. guinensis ( Schmalfuss & Ferrara, 1983) , from Guinea; C. kenyensis SchmÖlzer, 1974 , from Uganda and Tanzania; C. legai ( Arcangeli, 1941) , from Ethiopia; C. mineri ( Van Name, 1936) , from Venezuela and Guyana; C. parituberculatus ( Taiti & Ferrara, 1987) , from Malawi; C. regulus ( Van Name, 1920) , from Zaire and Somalia; and C. strinatii ( Schmalfuss & Ferrara, 1983) , from Congo. The species of the genus are mainly distinguished by the number and disposition of dorsal tubercles. In having four tubercles on pleonites 3 and 4 and two on pleonite 5 and telson, C. tuberosus resembles C. gabunensis , from which it differs in the number and disposition of tubercles on the cephalon and pereon (compare Fig. 75 View Figs 74-83 with Fig. 154 in SCHMALFUSS & FERRARA 1983).

Distribution. Haiti, St. Thomas Island, and Brazil (state of Bahia). It is also recorded from the Botanical Garden, Dahlem, near Berlin ( KESSELYAK, 1930; VAN NAME, 1936).
