Ceratophallus kigeziensis (Preston, 1912)

Fig. 2I

Planorbis kigeziensis: Preston 1912: 190 , pl. 32, figs 5a, b. (Type locality: “Kigezi, extreme S.W. Uganda,

at an altitude of 6000 ft. ”)

Planorbis (Gyraulus) avakubiensis: Pilsbry & Bequaert 1927: 127 , fig. 9. (Type locality: “Avakubi, in a woodland pool”)

Taxonomic remarks: Mandahl-Barth (1954) reports several localities for this species from Uganda, but also mentioned its possible occurrence in Rwanda and Burundi. Brown (1994) suggested that avakubiensis might be conspecific with kigeziensis . The former taxon was described by Pilsbry and Bequaert (1927) from near Nia-Nia, approximately 200 km west of our locality 24.

Habitat description: This species was dredged from L. Edward and the Semliki R. Note that the samples from localities 10 and 12 consist of empty shells only.

Collecting sites: 10, 11, 12.

IUCN Red List Category: Least Concern ( Jørgensen & Van Damme 2009).
