Abstract
Polydesmus biscayensissp. nov. and P. asturiensissp. nov. are described and figured based on material housed in the Museo Nacional de Ciencias Naturales in Madrid. The specimens were collected in six localities in the Asturias and Cantabria provinces, including four caves. In addition, Polydesmus haroi Mauriès & Vicente, 1977 and Polydesmus racovitzai Brolemann, 1910 are transferred from Propolydesmus Verhoeff, 1895 to Polydesmus Latreille, 1802/1803 after examining the gonopod morphology. A key to the Iberian Polydesmus species is presented.
Highlights
The Holarctic family Polydesmidae comprises of more than 240 occurring species, with 192 recorded in Europe (Kime and Enghoff 2011; Enghoff et al 2015)
Enghoff and Golovatch (2003) redefined the small and solely southwestern European genus Propolydesmus Verhoeff, 1895, adding 12 species formerly placed in Polydesmus and adding one previously recognized Propolydesmus in synonymy, increasing the number of included species from four to 15
Many of the species had been placed in subgenus Hormobrachium (Attems, 1940), that was synonymized with Polydesmus (s. str.) by Djursvoll et al (2001)
Summary
The Holarctic family Polydesmidae comprises of more than 240 occurring species, with 192 recorded in Europe (Kime and Enghoff 2011; Enghoff et al 2015). Two new species of Polydesmus are described below, based on material housed in the Museo Nacional de Ciencias Naturales, Madrid They were collected in northern Spain, from five localities in Asturias and one in Cantabria (Fig. 1). Based on the length and shape of the endomere and exomere, including the length and orientation of the seminal groove, the new species are placed in the genus Polydesmus, as diagnosed by Djursvoll et al (2001) Some of these character states are present in species considered by Enghoff and Golovatch (2003) to belong in the genus Propolydesmus, notably Polydesmus haroi Mauriès & Vicente, 1977 and Polydesmus racovitzai Brolemann, 1910. × Balearic Islands, Canary Islands, Valencia, Granada, Zamora, Huesca, Salamanca, Álava, Madrid, Segovia, Cuenca, Zaragoza, Toledo, Alicante, Guadalajara, Burgos
