| abstract | A new species, Ctenobelba heterosetosa sp. n., is described based on specimens from Ajara in the subtropical region of Western Georgia, collected from soil in a Castanea forest. The species differs from all described Ctenobelba species world-wide by the heteromorphic notogastral setae, which are broadened and phylliform in the anterior and centrodorsal part, strongly bacilliform in the posterior submarginal h-row, thin and fine in the posterior marginal p-row. The main characters of the new species are compared with those other Ctenobelba species with more or less phylliform notogastral setation. |
