Taxonomical remarks: This new species is characterized by its small size and low number of flagellar segments, stout flagellum, stout metasoma, granulate mesopleuron without distinct striation, bulging clypeus medially and dark color of palps and tegula. The form of clypeus resembles members of the genus Campodorus , but the 1 st tergite of Sc. minuta has no latero-median carina.
