Xinjiang Uygur Autonomous Region   : 2 ♂♂, Balian (43.26°N, 82.85°E), Mohe Town , Gongliu County, 1206 m, 5.viii.2007, coll. Xinpu Wang et al., genitalia slide Nos. ZML19286, ZML19318 GoogleMaps   .

Diagnosis. Adult ( Figs 19–20 View FIGURES 17–22 ) wingspan 15.5–16.0 mm. This species is similar to P. speciosella   both in adult and male genitalia, it can be distinguished from latter by the uncus with four branches about same height, middle incision normally not deeper than lateral incisions ( Figs 32–34 View FIGURES 31–34 ). In P. speciosella   , the uncus with middle branches higher than lateral branches and middle incision deeper than lateral incisions ( Figs 39–39d View FIGURE 39 ).

Variation. Uncus with middle incision variable, usually same depth with lateral incisions but can be deeper in some individual ( Figs 32–34 View FIGURES 31–34 ).

Distribution. China (Shanxi, Xinjiang), Japan, Korea, Russia, Europe, Asia Minor, North Africa ( Park & Karsholt 1999).

Remarks. Huemer & Karsholt (1999) and Park & Karsholt (1999) mainly used incisions on posterior margin of uncus and number of microspines (which we called microthorns in the present study) on phallus to distinguish P. gibbosella   and P. speciosella   in male genitalia: they considered uncus of P. gibbosella   with middle incision not deeper than lateral incisions, phallus with more than 20 microspines; while the uncus of P. speciosella   with middle incision deeper than lateral incisions, phallus with less than 16 microspines. Kaitila (1996) considered biology and colour of larvae as other effective evidence in identification of the two species. In this study, many more specimens have been checked and dissected. As expected, more morphological variations on genitalia are observed, but the microthorns on phallus and vinculum seemingly are unstable, therefore we don't think the two characters can hold as diagnostic features for Psoricoptera species.   We have not been able to collect or rear immature stages of the Psoricoptera species   , the larvae can be associated with adults taking advantage of molecular techniques in the subsequent study.
