Distribution. JAPAN: HONSHU ( NAGANO PREF.).— SOUTH KOREA: GANGWON-DO, GYEONGGI-DO ( KWON 1983, AS Psylla (Hepatopsylla)  pyricola).— CHINA ( JILIN, LIAONING).

Host plant. Pyrus ussuriensis  MAXIM. ( ROSACEAE  ).

Remarks. THERE ARE NO SIGNIFICANT DIFFERENCES IN THE MALE AND FEMALE TERMINALIA OF C. maculatili  AND C. qiuzili  , bUT THEY DIFFER IN bODY SIzE, FOREWING COLOUR AND SURFACE SPINULATION. WE INTERPRET THESE DIFFERENCES AS SEASONAL DIMORPHISM AND SYNONYMISE THE TWO NOMINAL SPECIES.

P. (H.) pyricola  bY KWON (1983) IS A MISIDENTIFICATION OF C. maculatili  AS SUGGESTED bY KWON’S DESCRIPTION AND CONFIRMED bY MATERIAL.

C. maculatili  , AS DEFINED HERE, RESEMbLES MORPHOLOGICALLY C. fera  (BAEVA) FROM TADzIKISTAN AND UzbEKISTAN ( BAEVA 1968; BURCKHARDT & HODKINSON 1986; LUO et al. 2012). C. fera  DIFFERS FROM C. maculatili  IN THE MORE RECTANGULAR (RATHER THAN TRIANGULAR) APICAL DILATATION OF THE DISTAL SEGMENT OF THE AEDEAGUS, THE HOST ( Pyrus korshinskyi  LITV. = Pyrus bucharica  LITV. VERSUS P. ussuriensis  ) AND THE GEOGRAPHICAL DISTRIbUTION (CENTRAL ASIA VERSUS EAST PALAEARCTIC). THESE DIFFERENCES, THOUGH SMALL, SUGGEST THAT C. fera  AND C. maculatili  ARE DISTINCT SPECIES.
