Figs 6–10 , Table 1 and 3

Material examined. Type material. Holotype male, Spain, Palencia, Redondo-Areñas, Puerto de Piedras Luengas, UTM: 30TVN86, 14.vii.1995, litter in Fagus sylvatica forest, sample C: 2296. Paratypes: female same data as holotype, sample C: 2296, three males same data as holotype, sample C: 2294. Holotype and paratypes in Universidad Autónoma de Madrid, Unidad de Zoología , Laboratorio de Entomología .

Description. Length 0.96 to 1 mm. Body without pigment, 4 + 4 eyes with pigment, two anterior corneola of the same size, the two posterior smaller, rate 0.76 ( Fig. 7 ).

Antenna without pigment, its proportion with head is 1.40. Rate of Ant. I:II:III:IV is 15:22:18:42. Ant. IV without apical bulb. Apical organ of third antennal segment peg or rod-like. Labial formula: M1 M2REL1 L2, all ciliated, ratio R with seta M1 is 2.1. R is one microseta ( Fig. 6 ).

Dorsal macroseta formula: R001/10/0101+2. Chaetotaxy of Abd. II: -aBq1q2 ( Fig. 10 ). Without accessory seta “s” on Abd. IV ( Fig. 8 , Tab. 1).

Tibiotarsus with capitate tenent hair, but specimens from sample C: 2294 have tenent hair acuminate, its rate with the length of internal unguis 0.78, differentiated inner seta on hind tibiotarsus clear acuminate. Unguis with an intermedian tooth, located about 64% of the length of the internal side of the unguis. There is a basal pair of teeth, one of them better developed, almost twice the size of the other, and located at 35% of internal side of unguis and the other is more distal and smaller, located about 53.5%. Empodium lanceolate and approximately 0,78 the length of unguis. Legs without scales ( Fig. 9 ). All other characters after Christiansen et al. (1999) ( Tab. 3). Retinaculum with 4+4 teeth and no seta in the base. With 2 inner and 2 outer seta in the manubrial plaque. Mucro bidentate, with one seta on its base.

Remarks. The new species presents the same dorsal chaetotaxy than: P. oromii Gama , P. decui Gruia , P. bohemica Rusek and P. pallida Gruia. They differ from all of them mainly by the number of eyes, chaetotaxy of Abd. II and the labial seta formula ( Table 1).
