Arbea 1, Javier I., Lopez 2, Virginia Garcia, Soria 2, Francisco Javier & Abellan 2, Pedro, 2021, Collembola from Hundidero-Gato Cave in Southern Spain, with the description of a new species of Entomobrya Rondani, 1861 (Collembola, Entomobryidae), Subterranean Biology 38, pp. 77-90 : 77

Folsomides cf. ayllonensis Simon & Lucianez, 1990

Folsomides ayllonensis New Sierra de Grazalema ( Málaga) record.

Material studied.

Cueva del Gato , dark zone, 30-IX-2016, 1 ex.

The species lacks pigment, but has 5+5 eyes. The juvenile (0.5 mm) examined differ from F. ayllonensis , as original description ( Simón and Luciáñez 1990) and notes made by Fjellberg (1993), in having an oval postantennal organ, 1.7-1.8 as long as omma (> 2 in F. ayllonensis ), and in having three posterior chaetae on dens (two in F. ayllonensis ).

The physical distance (≈ 690 km) and morphological differences between the Grazalema and Ayllón populations suggest they may represent distinct species, but additional material from Sierra de Grazalema will be needed to determine if the morphological differences noted here are fixed.
