Etymology. This species is dedicated to our dear colleague Dr. Rafael Jordana, for his contribution to the study of this group of springtails.

Description. Length from 0.96 to 1 mm. Body without pigment, 1+1 eyes with pigment, ( Fig. 12 ).Antenna without pigment, its proportion with head is 1.25. Ratio of antennal segments I:II:III:IV is 10:15:20:40. Ant. IV without apical bulb. Apical organ of third antennal segment peg or rod-like. Labial formula: M1M2rEL1L2 all setae ciliated, except r which is a microseta ( Fig. 14 ).

Dorsal macroseta formula: R011/10/0101+2.Chaetotaxy of abd. II: -aBq1q2 ( Fig. 15 ). Without accessory seta “s” on abdominal tergum IV ( Fig. 13 ).

Tibiotarsus with acuminate tenent hair, its ratio with the length of internal unguis is 0.58, differentiated inner seta on hind tibiotarsus, clear acuminate. Unguis with an internal median tooth, located about 66% of the distance from the base to apex of inner unguis. There is a basal pair of teeth, the proximal is located at 40% of the distance from base to apex of inner unguis and the distal is located about 50%.Empodium lanceolate, 0.6, as long as unguis ( Fig. 11 ). Legs without scales. Retinaculum with 4+4 teeth and no seta in the base.With 2 inner and 2 outer seta in the manubrial plaque. Mucro bidentate and with one seta on its base.

Remarks. In table 2, there are all the species with the same dorsal chaetotaxy as P.jordanai sp. nov. The new species is clearly different from the other mentioned species in the following combination of characters: number of eyes, labial and abdomen II chaetotaxy, absence of supplementary setae s, shape of the tenent hairs and the empodium.

*In the description of Stomp et al. (1982), the dorsal chaetotaxy given for P. leclerci is R011/10/0101+2 and for the second abdominal segment it is given pABqq, but not any drawing appears, that is why there is a question mark.
