Barycnemis dissimilis Gravenhorst 1829

Barycnemis dissimilis (Gravenhorst, 1829)

(Figs 1, 3)

Remarks. I have examined photographs of the holotype of B. funiuensis Sheng, described from Henan province in East China, and found that it is a typical representative of the Holarctic species B. dissimilis. According to its original description (Sheng 2002: 39), B. funiuensis differs from B. dissimilis by the following features: flagellum with 21–22 flagellomeres, malar space 0.77 times as long as basal mandibular width, mesopleuron smooth with sparse and fine punctures, foveate groove straight and reaching hind margin of mesopleuron, lateral part of propodeum smooth, and fore and mid coxae reddish brown. In B. dissimilis the antennal flagellum consists of about 22 flagellomeres; malar space varies from 0.5 to 0.8 times basal mandibular width (Fig. 1); mesopleuron is usually finely and sparsely punctate; foveate groove is weakly curved to almost straight, extending from epicnemial (prepectal) carina to lower posterior corner of mesopleuron, but sometimes is weak or evanescent anteriorly and/or posteriorly; dorsolateral areas of propodeum are finely granulate to smooth centrally; and fore and mid coxae are pale to conspicuously infuscate. Thus, all diagnostic features of B. funiuensis provided by Sheng (2002), as well as other characters in the original description, completely correspond with B. dissimilis, and therefore B. funiuensis is synonymised here with the latter species (syn. nov.).
