Verdcourt, B.: New and little known species of terrestrial Mollusca from East Africa and Congo (Kinshasa)

Materied examined - Tanzania, Meru Crater, S side, above Usa River, observation tower no. 17., 28.111.1979, leg. EŐRY & SlPOS HNHM 92293/19). Nesopupa bisulcata sinistra ssp. n. Type material - Holotype: Tanzania, 20 km from Arusha, Meru, S slope, Usa River settlement, (1200 m), 27.III.1979, leg. EŐRY & SlPOS (HNHM 93974). Paratypes: same date and locality as holotype (HNHM 92329/1); Kenya, Homa Bay, Bala, leg. PlCKFORD IRSNB). Diagnosis - Exactly similar to Nesopupa bisulcata bisulcata (JlCKELI, 1874) but constantly sinistral. Description - See ADAM (1954) descriptions and figures of N. iota (PRESTON, 1911) and /V. bisulcata (JlCKELI, 1873)). These differ only in being dextral. Distribution - Kenya, Homa Bay, Bala and Tanzania, Meru, Usa River. Etymology - Latin for left-handed. Remarks -VAN BRÜGGEN & VERDCOURT ( 1993) have already discussed this taxon treating it as a sinistral form although it was pointed out that all the population at Homa Bay was sinistral. The discovery of sinistral material at a site some 400 km away (both sites near water rather than being alpine) indicates that at least subspecific rank is necessary. FERUSSACIIDAE Cecilioides callipeplum (CONNOLLY, 1923) (Fig. 3) Opeas (Micropeas) callipeplum CONNOLLY, 1923 in Annals and Magazine of Natural History, ser. 9, 12: 657, t. 19, fig. 26; type locality: Kenya: Eusso Nyiro, BM 1937 12.30 4219 lecto. Distribution - Kenya, Malawi. Material examined - Kenya, Sanchu, 3°58 44'S, 39°44 96'E, 8.XI.2001. KONTSCHÁN & GERE HNHM 93975/1). Remarks - This single shell measuring 5.5 x 1.7 mm comes near the lower limits for this species but matches authentic material.
