  • 1986년 8월 한국 연근해에서 출현하는 Corycaeidae를 분류학적으로 연구하였다. 본 연구에서 기재된 종은 2속 3아속 9종으로 Corycaeus (Corycaeus) speciosus, G.(C.) crassiusculus, C. (Ditrichocorycaeus) affinis, C.(D.) andrewsi, C.(D.) erythraeus, C.(Onychocorycaeus) pacificus, c.(O.) catus, C.(O.) agilis, and Farranula gibbula 였다. 각 출현종의 분포를 보면 C. (O) affinis는 연안, 내만성종 의 특성을 나타내었으며, C.(C.) speciosus, C.(C.) crassiusculus, C.(O.) catus, andrewsi C.(D.) catus 및 Farranula gibbbula는 난류, 외양성종의 특성을 나타내었 다.

  • A new species of the genus Farranula Wilson, 1942 (Cyclopoida, Corycaeidae) is described based on both sexes collected off Chuuk Island in Micronesia (West Central Pacific). The new species F. dahlae differs from its close congener F. gibbula (Giesbrecht, 1891) in the following combination of characters in both sexes: body length is longer, length to width ratio of caudal rami is larger, basal element of maxilliped is distinctly longer, and terminal spine to distal segment ratio of P4 is smaller; while in females, lateral margins of fourth pedigerous somite are extended to mid-region of second urosomal somite, maximum width of the second urosomal somite is located at middle region in dorsal and lateral views, and length ratio of caudal seta III to seta V is much larger; and in males, sharply contracted portion of second somite is located at two-thirds distance from anterior margin. Some additional morphological details of F. gibbula are given and a key to species of the genus Farranula is provided.
