Plesiocypridopsini Jacobs & Martens 2022, trib. nov.
No full textTribe Plesiocypridopsini trib. nov. Type genus: Plesiocypridopsis Rome, 1965 We here select this common genus as the type genus, in order to avoid that the entire tribe would be based on a clade which is endemic to a single lake. Genera included: see Table 2. Differential diagnosis. Plesiocypridopsini trib. nov. is the sixth cypridopsine tribe (Table 2). It can be distinguished from the five other tribes as follows: the RV overlaps the LV at least anteriorly, most commonly also along the posterior and ventral sides, by which it is distinguished from the Cypridopsini; the A1 has a normal chaetotaxy, i.e. there are no apparent reductions in size of segments and number of setae, as in the Paranadopsini; the distal segment of the Mx1-palp is elongated, not spatulate, as in Potamocypridini; the A 2 in females lacks the strongly enlarge claw G2 as in the species in the tribe Zonocypridini; the T3 has a distal pincer organ, and there are no marginal septa on the valves, which separates it from the Cyprettadopsini in which segment 4 on T3 is separate from segment 3, and marginal septa occur.Published as part of Jacobs, Bram & Martens, Koen, 2022, An endemic species flock of Cypridopsinae (Crustacea, Ostracoda) from the ancient Lake Malawi (Africa), with the description of a new genus and three new species, pp. 301-348 in Zootaxa 5100 (3) on page 306, DOI: 10.11646/zootaxa.5100.3.1, http://zenodo.org/record/620124
Malawidopsis Jacobs & Martens 2022, gen. nov.
No full textMalawidopsis gen. nov. fuelleborni comb. nov. (Daday, 1910) (= spec. N) Fig. 18N Abbreviated description: elongated Cp, with almost symmetrically rounded anterior margin and bluntly pointed posterior margin, dorsal margin sloping towards the posterior side, ventral margin nearly straight. RV mildly overlapping LV along the antero-dorsal and postero-ventral margins. In dorsal view Cp relatively wide, with greatest width situated slightly behind the middle. Whole Cp densely set with small tubercles. Measurements: length of female = 707–730 µm; length of male = 691 µm. Localities. Original localities of Malawidopsis fuelleborni (Daday, 1910). No further information available, but it is assumed that all samples were taken from the shallow littoral. Sample 25: Plankton from Nyassa (= L. Malawi), SW, 5 km from Ikombe, 24/4/1899. Sample 34: Surface plankton from Nyassa (= L. Malawi), 19/08/1899. (sample 42): Plankton from Nyassa (= Lake Malawi), near Langenburg at edge, 27/08/1899. 1999 Usipa - locality: Metangula, Mozambique at 31 m depth (21/3/1999).Published as part of Jacobs, Bram & Martens, Koen, 2022, An endemic species flock of Cypridopsinae (Crustacea, Ostracoda) from the ancient Lake Malawi (Africa), with the description of a new genus and three new species, pp. 301-348 in Zootaxa 5100 (3) on page 336, DOI: 10.11646/zootaxa.5100.3.1, http://zenodo.org/record/620124
