Material examined. Spain, La Rioja, Leiva: female (holotype) from ecologic horticultural sample 4 LEHE 4, 20.i.2004; two specimens (paratypes) the same data as holotype in the samples 4 LEHE 1 and 2; one specimen from ecological fruit culture sample 4 LEFRE 2, 20.i.2004; Bañares: one specimen from a sample of soil of conventional fruit plantation 4BСFRC2, 15.viii.2003. C. Gutiérrez Martín coll. All the specimens on slides in the laboratory of Zoology of the Universidad Autónoma de Madrid, Spain.

Etymology. This species is named after the Villa de Leiva, La Rioja.

Description. Length 1.1–1.2 mm. Body without pigment, no eyes.

Antenna without pigment or scales, its proportion with head 1.14. Ant. IV without apical bulb. Apical organ of third antennal segment with two small straight rods, easy to observe.

Head with macrosetae R0, R1, R2, S, T and Po, macroseta R3 absent. Labial formula: -M2-EL1L2 ( Fig. 5 View FIGURES 5 – 8 ). Differentiated setae of outer labial papilla (E) straight and its apex almost reaching apex of papilla, with 3 sublobular setae on the external part of maxillary outer lobe. Four ciliated setae along the ventral cephalic furrow. Four triangular labral papillae.

Legs without scales, tibiotarsus with ciliate and acuminate macrosetae and with acuminate tenent hair, its rate with the length of internal unguis 0.78. Unguis with distal unpaired tooth located about 57 % the length of inner ungual membrane. Basal paired teeth with distal tooth twice the basal and about 52 % the length of the internal side of unguis; basal tooth about 35 % the length of the inner ungual membrane ( Fig. 6 View FIGURES 5 – 8 ). Unguiculus smooth and about 67 % the length of ungues.

Dorsal macrosetae formula: R111/00/0301+2. Chaetotaxy of Abd. II: pABQ1q2 ( Fig. 7 View FIGURES 5 – 8 ). Bothriotrical complex on Abd. IV without accesory seta “s” ( Fig. 8 View FIGURES 5 – 8 ).

Ventral tube with 6+6 smooth distal setae and 2+ 2 in the posterior medial region. Retinaculum with 4+4 teeth and one seta on the base. Distal part of manubrium with two internal and two external setae separated by two pseudopores. Mucro bidentate, with smooth basal spine.

Remarks. The new species is similar to P. v i t a Christiansen & Bellinger, 1980, P. f o l s o m i ( Mills, 1931), P. gamae Gisin, 1967 , and P. ioni Gama & Busmachiu, 2002 in the absence of eyes and the chaetotaxy of Abd. II. Besides differing in cephalic chaetotaxy the new species is easy to distinguish because it has ciliate setae in the labium. Pseudosinella leivaensis sp. nov. is clearly isolated from P. ioni because it has different labial and thoracic chaetotaxy ( Table 2 View TABLE 2 ).

*According description of Gisin, macrosetae R are absent
