Genus Yichunentulus Yin, 1980  new to RFE

Yichunentulus  Yin, 1980: 146-147, 155.

Type species.

Yichunentulus yichunensis  Yin, 1980.

Diagnosis.

Mesonotum and metanotum each with two pairs of anterior setae, abdominal appendages II and III each with two setae, labial palpus with one-branched terminal tuft of setae, with 3 setae and 1 sensillum, foretarsal sensillum t1 baculiform, sensillum b’ absent or present, sensillum a’ located distal to t1, maxillary gland simple and without appendages, sternite VIII with 4/2 setae, striate band on abdominal segment VIII reduced, and sternites II–VI each has 1+1 membranal pores.

Remarks.

The genus Yichunentulus  Yin, 1980 has only one species described from Heilongjiang, Northeast China ( Yin 1980). After compare Baculentulus borealis  Nakamura, 2004 with congeners, we find two important characters of this species: presence of one-branched terminal tuft of setae and 3 seate on labial palpus and 4/2 setae on sternite VIII are different to any other species of the genus Baculentulus  . On the contrary, those two characters match well with genus Yichunentulus  . Two specimens of Baculentulus borealis  newly collected from type locality are also studied. We proposed to transfer Baculentulus borealis  to the genus Yichunentulus  as a new combination Yichunentulus borealis  (Nakamura, 2004), comb. n. The three species of the genus Yichunentulus  can be distinguished by the following key.
