To increase our knowledge of the chilopod fauna of some poorly investigated regions of southern Spain, we arranged a collecting trip to Andalusia with a specific concentration on the Sierra de Grazalema and Los Alcornocales. As a result of hand collections and sieving at 21 localities we found altogether 20 species, 4 of them being new for Andalusia: Cryptops trisulcatus Brölemann, 1902; Algerophilus hispanicus (Meinert, 1870); Stigmatogaster superba (Meinert, 1870) and Henia vesuviana (Newport, 1845). For each of the species, records notes on general distribution, morphology and ecology are given. Taxonomic problems are discussed in relation to literature records.
