03BF1009420DFF9E8BB28E7849A8CC47.taxon	discussion	Remarks. In this redescription new morphological characters are added, such as chaetotaxy of head; length of seta on head, nota and foretarsus; porotaxy and lineation of tergites and sternites; shape of maxillary palp sensilla, comb and male squama genitalis. According to Imadaté (1980), in P. americana the shape of the accessory setae on the tergites is sensilliform and acrostyli are pointed. However, reexamination of the type material indicates that shape of accessory setae on the tergites is setiform, and acrostyli are not pointed, but trilobed. Paracerella americana is similar to P. s h i r a t k i in the pattern of foretarsal sensilla, but it differs from the latter species by the presence of 8 and 6 pairs of anterior setae on tergites VII and VIII, respectively (6 and 4 pairs of A - setae in P. shiratki), absence of seta P 1 a on tergite VII and by the shape of the comb.	en	Shrubovych, Julia, Smykla, Jerzy (2012): Review of Paracerella Imadaté (Protura: Acerentomidae, Nipponentominae) with identification key and description of a new species.

03BF1009420FFF988BB28BBA4B6FCFB3.taxon	etymology	Etymology. The specific name is derived from Monterey County, where the holotype was collected. Remarks. In chaetotaxy P. monterey sp. nov. is very similar to P. americana. Both these species are characterized by the absence of additional cephalic setae, by setiform shape and short length of head setae l 3, sd 4 and sd 5. The new species differs from P. americana in the absence of seta P 1 a on tergites I – VI, presence of 2 posterior setae on sternite I (4 P - setae present in P. americana) and in shape of the comb. Foretarsal setae β 1 and δ 4 are longer than other δ-setae in P. monterey sp. nov. and seta δ 4 is longer than β 1 (11 and 8 μm, respectively), whereas β 1 and δ 4 are shorter than the other δ-setae and foretarsal setae β 1 and δ 4 are of similar length in P. americana. The lengths of notal setae are similar in both species with the exception of seta P 1 a, which in P. m o n t e re y sp. nov. is twice as long as P 2 a. Paracerella monterey sp. nov. is also characterized by peculiar lineation in anterior parts and presence of granulated areas posteriorly on sternites IV – V. These characters seem to be stable on species level. Porotaxy, maxillary sensillum shape and appearance of male and female squama genitalis are identical in both species.	en	Shrubovych, Julia, Smykla, Jerzy (2012): Review of Paracerella Imadaté (Protura: Acerentomidae, Nipponentominae) with identification key and description of a new species.

03BF1009420FFF988BB28BBA4B6FCFB3.taxon	discussion	Discussion. All species of Paracerella are characterized by a maxillary gland with a racemose appendage on the distal part close to the calyx, similar foretarsal length and similar pattern of foretarsal sensilla. Sensillum a reaches to the base of sensillum t 2, b is equal in length with c, b is broad, sensilla d, f and c' are very long and narrowed distally; the base of sensillum d is slightly closer to e than to c, and the base of a' is level with t 2. The three Paracerella species clearly differ in chaetotaxic characters (see the key) and in some other morphological characters.	en	Shrubovych, Julia, Smykla, Jerzy (2012): Review of Paracerella Imadaté (Protura: Acerentomidae, Nipponentominae) with identification key and description of a new species.
