Protura Acerentomidae Fjellbergella CoL Animalia Fjellbergella Protura 10 29 Arthropoda genus  Taxon classification Animalia Protura Acerentomidae  Type species.  Fjellbergella tuxeniNosek, 1980.  Diagnosis. Mesonotum and metanotum each with two pairs of anterior setae, labial palpus with two-branched terminal tuft of setae, sensillum d located near t2 insertion, abdominal appendages II and III each with three setae, foretarsal sensillum t1 claviform, sensillum b'present, striate band on abdominal segment VIII reduced and sternite VIII with 4/2 setae.  Remarks. The genus Fjellbergellacontaines only two species so far: Fjellbergella tuxeniNosek, 1980 from Alaska and Fjellbergella uteorumShrubovych & Bernard, 2013 from Colorado ( Nosek 1980; Shrubovych and Bernard 2013). Except that, one species of the similar form Brasilidia jilinensisWu & Yin, 2007 was also found from Northeast China. However, the species of genus Brasilidiahas reduced labial palpus without tuft, and all of them occurred in tropical area (South America and India). After recheck the type specimens, we confirmed that Brasilidia jilinensishas reduced striate band, the labial palpus with reduced tuft (two-brunched), and three setae on abdominal appendages II and III which indicate it is a member of Fjellbergella. Thus we transfer Brasilidia jilinensisto the genus Fjellbergellaas a new combination Fjellbergella jilinensis(Wu & Yin, 2007), comb. n. Plus the new species described in present paper, the genus Fjellbergellacontains 4 species. They can be distinguished by the following key.   Keyto the species of genus FjellbergellaNosek, 1978    Pc  Pc  Fjellbergella uteorum  P1a  Fjellbergella jilinensis  P1a  bc  Fjellbergella lazovskiensis  bccb  Fjellbergella tuxeni
