Review of the Eustrophinae (Coleoptera, Tetratomidae) of America north of Mexico Author Pollock, Darren A. text ZooKeys 2012 188 1 153 http://dx.doi.org/10.3897/zookeys.188.2976 journal article http://dx.doi.org/10.3897/zookeys.188.2976 1313-2970-188-1 Pseudoholostrophus Nikitsky 1983 Pseudoholostrophus Nikitsky 1983 : 37.-Type species: Hallomenus klapperichi Pic 1954 (orig. des.); Nikitsky 1998 : 40; Young and Pollock 2002 : 416; Nikitsky 2008 : 63; Pollock 2008 : 268. Note. This genus was described by Nikitsky (1983) on the basis of examination of Hallomenus klapperichi Pic, which now is included in (and is the type species of) Pseudoholostrophus . According to Nikitsky (1998) , Pseudoholostrophus differs from Holostrophus in its smaller and more weakly emarginate eyes, and in the prosternal process not extending behind the posterior edge of the procoxae. There are four species in Pseudoholostrophus ( Nikitsky 1998 ), two of which are Nearctic in distribution. The other two species, Pseudoholostrophus klapperichi (Pic) and Pseudoholostrophus chinensis Nikitsky, are known from China. Nikitsky (1998) divided the genus into two subgenera; all species other than Pseudoholostrophus discolor (Horn) are placed in the nominate subgenus. Holostrophus discolor (Horn) was transferred into the subgenus Holostrophinus of Pseudoholostrophus by Nikitsky (1998) . There are two Nearctic species in this genus.
