First descriptions of copepodid stages, sexual dimorphism and intraspecific variability of Mesocletodes Sars, 1909 (Copepoda, Harpacticoida, Argestidae), including the description of a new species with broad abyssal distribution
Mesocletodes Sars, 1909a encompasses 37 species to date. Initial evidence on intraspecific variability and sexual dimorphism has been verified for 77 specimens of Mesocletodes elmari sp. n. from various deep-sea regions, and ontogenetic development has been traced for the first time. Apomorphies are a strong spinule-like pinna on the mx seta that is fused to the basis, P2-P4 exp3 proximal outer...
متن کاملReduced Skull Sexual Dimorphism in a Local Sheep Breed
This study estimated the magnitude of sexual dimorphism in a relict sheep from Catalunya (NE Spain), called Fardasca,using geometric morphometric techniques. For these analyses, a total of 18 skull specimens (2 adult males and 16 females) were studied. Our results suggest that the breed is not cranially dimorphic, so sex determination using landmarks described here as criteria is likely to yiel...
متن کاملThree new species of Parastenocarididae (Crustacea, Copepoda, Harpacticoida) from India.
To date, only 16 species of the very diverse family Parastenocarididae have been reported from the Indian subcontinent. This paper gives an illustrated description of three new species, viz. Parastenocaris edakkal n. sp., Proserpinicaris corgosinhoi n. sp., and Proserpinicaris karanovici n. sp., and discusses their position in the respective genera. While the first two species were found sympat...
متن کاملParastenheliidae (Copepoda: Harpacticoida) from the Isles of Scilly
Three species of Parastenheliidae were found at a sampling site around low tide level on St Martin’s Flat in the Isles of Scilly. The most abundant species in the community was identified as Parastenhelia ornatissima but detailed study, particularly of the previously unknown male, indicates that this species has a sexually dimorphic antenna and belongs in the genus Karllangia as K. ornatissima ...
متن کاملTwo new species of Leptopsyllus from Korea (Copepoda, Harpacticoida, Paramesochridae)
Two new species of Leptopsyllus are described from the subtidal zone of Korea. Both species were assigned to the subgenus Leptopsyllus (Leptopsyllus) T. Scott, 1894, based on following three characters: two-segmented rami of P1, absence of endopod on P2 and P3, and presence of one-segmented endopod of P4. L. (L.) pundius sp. n. is most closely related to L. (L.) punctatus Mielke, 1894, however ...
