03E287CBFF97FFFCDF7EF906FC36E5E7.taxon	description	Habitus of Xenylla. Body length 0.36 – 1.50 mm, with blue pigment, PAO absent, with 5 + 5 eyes. Mouthparts modified with tendency to a type for chewing. Labral setae 7 / 5, 5, 4. Antennae of Xenylla type, but sensorial organ of antennal segment III with five similar elements, ventral guard setae between the sensorial rods. Antennal segment IV with four thick sensilla, one microsensillum, one subapical organ and a simple apical bulb. Tenent hairs capitate or acuminate. Unguis without empodium, with or without a median teeth. Furcula well developed, mucro completely or partially separate from dens. Tenaculum with 2, 3 or 4 teeth on each ramus. Anus terminal and abdominal segment VI as a truncate cone. Anal spines absent. Chaetotaxy of Type I, with mesosetae and macrosetae. Dorsally on thoracic segments II and III with m 2 (absent in Xenylla) as a macroseta. On abdominal segments I – IV, p 2 is a macroseta; on abdominal V a 1 is a macroseta and ss at p 4. Ventral chaetotaxy of the head and abdominal segments I – III reduced. Ventral tube with 1, 2, 3 or 4 setae per side. The following species, originally described under the genus Xenylla, probably belong to Paraxenylla and need revision: littoralis Womersley, 1933, longicauda Folsom, 1898 and occidentalis Womersley, 1933.

Tenaculum with 2 teeth on each ramus (Fig. 7). Mucrodens (20 µm) apparently with only one seta (Fig. 8). Female with 3 + 3 pregenital setae, 2 – 3 genital and 2 eugenital (Fig. 9).

03E287CBFF94FFFADF7EFBE4FD7BE507.taxon	etymology	Derivatio nominis: from the country where this species was found: Cuba. Type locality: Cuba: Guanacabibes. Type Material: Holotype Ψ, two paratypes ♂♂. Kept at senior author’s collection. 1 ­ XII­ 1989, M. Díaz Azpiazu col. Discussion: The most distinctive and easy character to separate Paraxenylla cubana sp. nov. from the others is the presence of only 2 + 2 teeth on the retinaculum, and only one dental seta. Another important character is the presence of four globular sensilla, while in the other congeneric species they are cylindrical. This is the only species with reduction of the tibiotarsal setation.	en	Palacios-Vargas, José G., Janssens, Frans (2006): Two new American species of Paraxenylla (Collembola: Hypogastruridae) and ecological notes.

03E287CBFF92FFFBDF7EFC44FB7EE55F.taxon	description	Body length (n = 5) 1,230 µm (range 1,020 – 1,480 µm). Body with moderate short acuminate setae (13 – 15 µm). Macrosetae and sensorial setae long (26 – 28 µm) almost two times the length of ordinary setae. Color dark blue, eye patches black. Ratio head: antenna = 1: 0.7.

03E287CBFF92FFFBDF7EFC44FB7EE55F.taxon	etymology	Derivatio nominis: from the country where this species was found: Peru. Type locality: Peru: Departamento de Ica: Baha de Paracas, Reserva Nacional de Paracas. Type Material: Holotype Ψ, two paratypes ΨΨ will be send to Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Peru; two paratypes ΨΨ, and one paratype ♂ will kept at senior author’s collection; 2 paratypes kept at junior author's collection, 9 ­ V­ 2003. All specimens collected at the beach on green algae Ulva sp. A. Catanazzi col. Discussion: The most distinctive and easy character to separate Paraxenylla peruensis sp. nov. from the others is the presence of one smaller sensillum on Ant. IV. The tenent hairs position on tibiotarsi is a differential character, one being dorso­distal, one ventrodistal and two ventro­proximal. Among all the congeneric species this is the only one with this combination. This is the biggest species, almost 1.5 mm. The European P. affiniformis (Stach, 1930) sensu Gama & Deharveng, 1984 measures between 750 – 900 µm.	en	Palacios-Vargas, José G., Janssens, Frans (2006): Two new American species of Paraxenylla (Collembola: Hypogastruridae) and ecological notes.
