Both rami fused medially. Endopodal lobe small, bearing 1 bipinnate and 1 small naked setae.

Present specimen is closely related to + +Orthopsyllus linearis curvaspinata +Mielke, 1993 + +. Both species share the distinct characters of the sexually dimorphic caudal seta V which is longer in the male than in the female ( +Figs. 1C +and +7E +), the modification of outer apical spine on the P2-P3 exp-3 (Figs. 8B and 9C), only two elements on the male P6. However they display several discrepancies including 1) bulbous caudal seta V in the female in + +O. linearis curvaspinata + +while slender in the present specimen, 2) long- er and rectangular caudal rami in + +O. linearis curvaspinata + +, while shorter and ovoid in the present specimen, 3) one more seta on the P3 enp- +2 in + +O. linearis curvaspinata + +, and 4) longer P2 and P4 enp- +2 in +the male of + +O. linearis curvaspinata + +. There is complex history of discussion on the genus + +Orthopsyllus + +( +Vervoort, 1964 +; +Lang, 1965 +; +Boer, 1971 +; +Huys, 1990 +), and many authors created subspecies within the +type +species rather than establishing species due to the incomplete previous description of +type +species, + +O. linearis +(Claus, 1866) + +as +Mielke (1993) +also pointed out. It is difficult to decide the status of present specimen from +Korea +with the poor comparisons with other congeners, which would take a time for a while, however the report of unrecorded genus in local area has a meaning. Therefore we tentatively regarded Korean species as + +Orthopsyllus +cf. +linearis +(Claus, 1866) + +rather than establishing another new subspecies. It would be interesting if we get the further evidence including molecular data revealing the status of + +Orthopsyllus +cf. +linearis +(Claus, 1866) + +in further study. + + + + \ No newline at end of file
