Figure 55 in Macrocyprididae (Ostracoda) from the Southern Ocean: taxonomic revision, macroecological patterns, and biogeographical implications

Figure 55. Chaetotaxy of antenna II of Macroscapha opaca Maddocks, 1990. A–K, adult male; M, N, adult female (ZMH K-41491). A–C, distal tip of sexually dimorphic seta of podomere V (note the absence of a perforation, which would be typical of aesthetascs); D, three (two modified plus one simple) distal setae of podomere V; E, detail of the exopodite, showing insertion on the distal margin of podomere II; F, medial view of antenna II of male; G, H, detail of proximal, pinnate setae of podomere III (= podomere I of endopodite); I, distal tip of proximal, pinnate setae of podomere III (note the absence of a perforation, which would be typical of aesthetascs); J, K, detail of dorsal setae of podomere IV; L, distal tip of dorsal setae of podomere IV (note perforation); M, medial view of antenna II of female; N, distal, sexually dimorphic setae of podomere V. Scale bars: A, H, I, K = 1 Mm; B, C = 2 Mm; D, E, G, J, M = 10 Mm; F, N = 100 Mm; L = 200 nm.
