Stoev, Pavel & Enghoff, Henrik, 2004, The first indigenous species of the millipede genus Eurygyrus C. L. Koch, 1847 from the European mainland, with remarks on E. nicarius (Verhoeff, 1901) and E. euboeus (Verhoeff, 1901), and a key to the species of the genus (Diplopoda: Callipodida: Schizopetalidae), Zootaxa 419, pp. 1-8 : 5

Eurygyrus euboeus ( Verhoeff, 1901)

Figs 7–8 .

Material examined: Holotype: adult female, discolored, broken into five pieces, labelled “ Lysiopetalum euboeum Verhoeff, Süd Euboea, Stura , v. Oertzen leg. 24.03.1887 ”; ZMB 2415 .

Description: Large callipodid, markedly larger than E. peloponnesius . Trunk composed of 46 pleurotegites + telson. Color (after more than 115 years in alcohol): below the level of ozopores yellow­brownish, dorsum dark brown. Ozopores surrounded by lighter yellowish spots, which merge with yellowish base of pleurotergite, and forming a row along the body. Crests moderately pronounced on anterior pleurotergites, more pronounced on posterior ones ( Fig. 7 ). Prozonites with medial yellowish spots forming lighter band along the body. Hypoproct composed of three sclerites; medial sclerite largest, bearing two paramedian macosetae. Anal valves densely covered with setae ( Fig. 8 ).

Remarks: Despite the fact that the shape of the male gonopods is still unknown, reexamination of the type of E. euboeus showed that the form of crests and the divided hypoproct well distinguish it from E. peloponnesius . Other characters that could be of some value for species separation are the body size and coloration.
