Figs 9–12 , Table 3

Material examined. Spain, La Rioja, Bañares: female (holotype) and three specimens (paratypes) from ecologic fruit culture 4BСFRE5, 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 dedicated to our colleague and friend Carmen Gutiérrez, Senior Researcher at the Consejo Superior de Investigación Científica of Spain.

Description. Length 1.25 mm. Body without pigment, 3+3 eyes, two anterior corneola and one posterior far from the others.

Antenna without pigment, its proportion with head 1.45. Ant. IV without apical bulb. Apical organ of third antennal segment with two small rods.

Head with macrosetae R0, R1 and R2, T and Po, macrosetae R3 and S absent. Labial formula: M 1m 2-el1l2 ( Fig. 9 ). Differentiated setae of outer labial papilla (E) straight and its apex almost reaching apex of papilla, with three sublobular setae on the external part of maxillary lobe. Four ciliated setae along the ventral cephalic furrow. Four triangular labral papillae.

Legs without scales, tibiotarsus with ciliate and acuminate macrosetae, with acuminate tenent hair, its rate to the length of internal unguis 0.57. Unguis with distal inner unpaired tooth located at 75 % the length unguis. Inner basal paired teeth with distal tooth twice the basal, inserted at about 66 % the length of inner membrane from the base, the other tooth inserted at about 47 % the length of the ungues ( Fig. 10 ). Unguiculus smooth and about 76 % the length of ungues.

Dorsal macrosetae formula: R011/00/0201+2. Chaetotaxy of Abd. II: paBQ1q2 ( Fig. 11 ).. Anterior bothriotrical complex of Abd. IV with accesory seta “s” ( Fig. 12 ). Ventral tube with 6+6 smooth distal setae and 2+ 2 in the posterior medial region. Retinaculum with 4+4 teeth and one ciliate seta. Distal part of manubrium with two pseudopores, 2 internal and 2 external setae. Mucro bidentate, mucronal spines smooth.

Remarks. The new species P. gutierrizae sp. nov. has the same dorsal chaetotaxy and number of eyes as P. sexoculata sensu Gisin & Gama (1972) , P. sexoculata sensu Wang et al. (2004) , and P. simoni Jordana et al. , but it differs from the others in having a tibiotarsus acuminate tenent hair. Besides, it can be distinguished from the first species by the lack of r seta in the labial base. From the second and third species it differs in having smooth m2el1l2 seta and from P. s i m o n i in not having the p seta in the II abdominal segment.

In table 3 the differences from this species and P. sexoculata sensu Christiansen & Bellinger (1980) are shown, this latter species has the dorsal chaetotaxy different from the others.

rax-abdomen chaetotaxy. Number of the state characters follow Christiansen et al. (1990). Only differentiated characters

are given.
