Pelomedusa barbata — TTWG 2017: 202 
DistributionYemen

Type locality: Zinjibar, Abyan, Yemen, N13°7.75 E45°22.81  
Reproduction 
TypesHolotype: MTD D 24637 (Museum für Tierkunde, Senckenberg Dresden), male; leg. W. Wranik, 3 June 1985; Fig. 3 top).
Paratypes: Muséum d’Histoire Naturelle Genève (MNHG 2310.062, adult male, Al Sukhna, Yemen; MNHG 2455.073–075, adult male and two juveniles, Wadi Warazan, Lahij, Yemen); Museum für Tierkunde, Senckenberg Dresden (MTD D 24638, adult female, Lahij, Yemen); The Natural History Museum, London (BMNH 1985.1475, mummified adult, Al Kadan, Tihama, Al Hudaydah, Yemen; BMNH 1985.1478–1479, adult male and female, Amanat Al Asimah, Sana’a Area, Yemen); Zoologisches Forschungsmuseum Alexander Koenig, Bonn (ZFMK 87122, juvenile, Asir Region, Saudi Arabia). 
DiagnosisDiagnosis: Medium-sized, light-coloured helmeted terrapins with a known maximum straight carapacial length of 21.6 cm (Gasperetti et al. 1993). Pectorals with narrow to broad midseam contact. Two small temporal scales (rarely only one large scale) on each side of head. Two or three large to very large barbels under chin. In adults, carapace light coloured, plastron entirely yellow. Pelomedusa barbata differs from all other Pelomedusa species by a gap instead of adenine (A), cytosine (C) or thymine (T) at position 122 and by the presence of guanine (G) instead of adenine (A) at position 330 of the 360-bp-long reference alignment of the 12S rRNA gene (Supporting Information) [from PETZOLD et al. 2014].
 
CommentPhylogenetics: Pelomedusa barbata corresponds to mtDNA lineage VII of Vargas-Ramírez et al. (2010). According to our analyses of mtDNA, P. barbata belongs to the northern species group of Pelomedusa and is most closely related to P. somalica (Fig. 1).
