SynonymAmphiglossus nanus ANDREONE & GREER 2002: 144
Amphiglossus nanus — SCHMITZ et al. 2005 
DistributionNE Madagascar

Type locality: at Anjanaharibe-Sud Massif, Analabe Valley, Campsite W1, Befandriana Fivondronana, Mahajanga Faritany (Majunga Province),
14°46'S, 49°27'E, elevation 1000 m.  
Reproductionoviparous (phylogenetic imputation, fide Zimin et al. 2022) 
TypesHolotype: MRSN R1803 
DiagnosisDiagnosis: Differs from all other species of Amphiglossus except A. macrolepis (holotype and only known specimen examined: BMNH 1946.8.21.23) by its very small size (SVL < 33.5 mm) and loreal not extending ventrally to supralabial row. Distinguished from A. macrolepis by its possibly even smaller size, with maximum SVL of 29mm instead of 33.5mm; separation of loreal from supralabial row by contact between postnasal and enlarged presubocular instead of by contact between postnasal and preocular (Fig. 7); scales between lower secondary temporal and ear opening two instead three; longitudinal scale rows at mid-body 20 instead of 18, and subdigital lamellae on fourth digit of pes 6±9 instead of 5 (Andreone et al. 2002). 
Comment 
EtymologyNamed after the Greek word “nanos” = small, dwarf (maximum SVL =29 mm).
