Plesiocypridopsini, Jacobs & Martens, 2022

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, Zootaxa 5100 (3), pp. 301-348 : 306

Tribe 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.
