Summary: | Arctocypris fuhrmanni n. gen., n. sp. (Figs 2–5) Etymology. The species is named in honour of the ostracod researcher Roland Fuhrmann, Leipzig, Germany. Holotype. 1 female Nr. ZMH K- 42963 Paratypes. 40 females Nr. ZMH K- 42964 Type locality. ‘Thorshühnchen-Teich’, a pond on the island Måkeøyane in the Liefdefjord (Northern Spitsbergen, Svalbard, Norway). Collected by H.-J. Spitzenberger in August 1990 and August 1991. Material examined. 41 adult females, mostly decalcified and slightly or strongly macerated. Associated fauna: In the sample of August 13, 1991 from ‘Thorshühnchen-Teich’ 2 females of Tonnacypris glacialis (Sars, 1890) and 1 female of Fabaeformiscandona sp. Description (Figs 2–5): Carapace. LV (Figs 2 A, 5): In lateral view dorsal margin blunt at point of greatest height, slightly bulged antero-dorsally. Anterior margin broadly rounded. Dorsal margin also slightly bulging postero-dorsally and with small indentation. Posterior margin narrower than anterior. Ventral margin slightly indented and bulging around mouth region. Surface covered with distinct, rounded depressions, frontally with small wart-like pores. Whole carapace with simple open pores. Calcified inner lamella broader anteriorly than posteriorly. Inner list more elevated in the anterior than in the posterior. Selvage peripheral, fused zone anteriorly broader than posteriorly. RV (Figs 2 B and 5): In lateral view nearly triangular. Greatest height frontal from the middle, higher than half of the length. Dorsal margin bluntly angled at point of greatest height, slightly sloping towards frontal end, then gently indented and extending into the broadly rounded frontal margin. Dorsal margin more inclined towards posterior than towards anterior end, postero-dorsally with small indentation. Posterior end narrow. The ventral margin slightly concave and enlarged around mouth. Surface ornamentation as on LV. An outer list exists and is running parallel to the flange. Two parallel inner lists present more pronounced on the anterior calcified inner ... |
