urn:lsid:zoobank.org:act:A9807D5A-DF4A-444E-ABC5-A13B171A3131 ( Figs. 2 A-E, 8S)

Type material: Holotype: Adult female, on slide, under access number RO-Fr147- IBB, deposited at IBB . Paratypes: Two females (ROFr110 deposited in IBB and RO-Fr148, deposited in ISEA).

Type locality: Olt Valley, Malaia locality, Vâlcea County, Romania (45°21'11.18"N, 24°01'11.74"E), 494 m alt., beech forest, leaf litter near rocks, 01.xi.2012, leg. C. Fiera ( IBB).

Etymology: The new species is dedicated to Mircea Fiera , husband of the first author, who helped several times in the field studies of Collembola.

Description: Habitus and buccal cone typical for the genus Friesea . Length: Holotype female: 0.56 mm. Paratypes female: 0.65-0.78 mm. Colour blue in alcohol. Integument secondary granules rather small.

Antennae about 2/3 of head length. Antennal segment I with 7 chaetae, antennal segment II with 13 chaetae (11-14). Sensory organ of antennal segment III consisting of 2 small subcylindrical internal s-chaetae, 2 subcylindrical guard s-chaetae, (ventral one longer and “s” shaped) and s-microchaeta. Antennal segment IV with 6 subcylindrical s-chaetae (S1-4, S7-8 present), 1 small s-microchaeta placed between S7 and S8, and 1 small subapical organite. Apical vesicle simple ( Fig. 2B ).

Ocelli 5 + 5, postantennal organ absent. Chaetotaxy of labrum: 4/5,3,4. Labium with papillated chaeta L ( Fig. 2C ).

Dorsal chaetotaxy as in figure 2A, sometimes with asymmetry, with relatively short (longer on posterior abdominal terga), subequal chaetae and slightly longer s-chaetae (subequal to longest ordinary chaetae on abdominal terga IV-V. Their formula per half tergum: 022/11111. Head with (paratypes) or without (holotype) chaetae a0, with chaeta d0 and 3 chaetae oc. Thoracic tergum I with 4 + 4 chaetae. Thoracic tergum II with 12 + 12 chaetae (4 chaetae Di including a2, 4 De including s-chaeta in position of p3, 4 Dl including one s-chaeta and one s-microchaeta (ms)). Thoracic
