TRIBE DISCOSOMATICINI ROEWER, 1923 STAT. DEM.

Discosominae Pickard-Cambridge, 1904: 549. Nomen permanently invalid, being based on a genus nomen preoccupied by Discosoma Rueppell & Leuckart, 1828 (Cnidaria) .

Discosomaticinae Roewer, 1923: 388 .

Diagnosis: Small and delicate cosmetids with long and unarmed legs (Figs 42B, 46B). Area III of mesotergum may be unarmed (Fig. 46C, D), bear acuminated spines ( Marronia) or high, rounded tubercles ( Kayania, Fig. 24D, E). Area I with small, rounded tubercles, sometimes coloured (Fig. 33B). Other areas may be unarmed or with paramedian, low, yellow tubercles. DS rounded in dorsal view (delta-type) and lenticular in lateral view (Fig. 42A, C), constriction between carapace and abdomen not well marked (= constriction C1, Fig. 5A). Chelicerae monomorphic without basal spine in movable finger (Fig. 43E). Yellowish spots (if present) are mostly restricted to four dots in areas I and III, and as marginal stripes in DS (Figs 35A, 42A). Lateral part of coxa IV sometimes with yellowish markings (from dots to stripes, Figs 33B, 44C). Bipectinate claws in legs III and IV, (Figs 32E, F, 36H, I). Basitarsomeres slightly enlarged in males, but not inflated.

Type genus: Discosomaticus Roewer, 1923 (a junior subjective synonym of Sibambea).

Included genera: Paraprotus Roewer, 1912; Protus Simon, 1879; Sibambea Roewer, 1917; Kayania Medrano, Kury & Mendes gen. nov. and Marronia Medrano, Kury & Mendes gen. nov.

Remarks: The original name of the type genus Discosoma Perty, 1833 was pre-occupied by a genus of cnidarians, therefore, Roewer proposed the replacement name Discosomaticus Roewer, 1923 and at the same time he proposed the new replacement name Discosomaticinae for the subfamily (ICZN Art. 39; Kury, 2018).
