Description. Maximum length 1,0- 1.3 mm (Holotype: 1,0 5 mm). Apparently without pigment. 3+3 eyes. Ratio antenna/cephalic diagonal 1,3 and 1,5. Antennal segments I/II/III/IV ratios 2.05/1.14/1.31/1.00 (n = 2). Sensorial seta s of the sensory organ of antennal segment III expanded (leaf shaped). Apical vesicle absent from antennal segment IV.
Formula of the labial base (Fig. 22): M1M2rEL1L2 (all setae ciliated except r, that is a vestigial microchaeta.
Formula of the dorsal macrochaetae: R011/00/0201+2. Anterior seta to pseudopore thoracic II absent. Abdominal tergite II chaetotaxy: - aBQ1q2 (Fig. 20). B and Q as broad ciliated and pointed macrochaetae. R complex: R0 to R2 present (Fig. 21). Accessory seta s in the anterior trichobothrial complex of abdominal tergite IV present (Fig. 23). Seta P on abdominal tergite IV slightly anterior to the trichobothrium (Fig. 24). Medial seta M1 between the trichobothria T1 and T2; pseudopore nearest M1.
Unguis (Fig. 25) with dental plate occupying 60% of the basal internal edge; one of the basal tooth slightly bigger than the other one; medial tooth well developed, approximately 70% from base of total unguis. Unguiculus appendage acuminate with small denticles. Dorsal tibiotarsi tenent hair clavate. Legs without scales. Retinaculum with 4 + 4 teeth and one ciliated seta. Two internal and two external setae related to two distal pseudopores of manubrial plate. Mucro with distal tooth longer than the anteapical; the basal spine reaches just to the tip of the distal tooth.
Etymology. The species name is dedicated to Dr. José Carlos Simón, Spanish collembologist.
Discussion. P. s i m o n i sp. nov. has a unique macrochaetotaxy. The closest species with the same macrochaetae formula is: P. sexoculata Schött, 1902 (3 + 3 eyes, R011/00/0201+2, paBQ1q2, M 1m 2rel1l2, accessory seta s present) (Table 3).
