Ebenavia boettgeri — HAWLITSCHEK et al. 2018 
DistributionMadagascar (lowlands of the eastern rainforest belt from Sainte Luce in the southeast to Ambodivoahangy and possibly Ambohitralanana on the Masoala Peninsula in the northeast); elevations from sea level to 425 m.

Type locality: “Madagascar”  
TypesHolotype: BMNH, adult female; collected by an unknown collector on an unknown date. 
DiagnosisDiagnosis: The holotype is distinguished from E. inunguis and E. safari sp. nov. by the nostril in contact with the rostral and from E. robusta sp. nov. by the absence of distinctly enlarged tubercles on the hindlimbs. The name Ebenavia boettgeri Boulenger, 1885 is therefore assigned to the East Coast Clade (Cc) of Hawlitschek et al. (2017), with which the holotype agrees in all characters.

Morphological data is given in Table 2 and ESM 1 in Hawlitschek et al. 2018, a photograph of a living specimen is shown in Fig. 4b. Distinguished from Ebenavia maintimainty by larger SVL (28.9–37.8 vs. ≤ 24 mm), rostral scale bordered by postrostrals distinct from posterior head scales, absence of prenasal scale between rostral and nostril, keeled abdominal scales, and lighter colour; from E. robusta sp. nov. by absence of distinctly enlarged tubercles on hindlimbs (TUB = no), smaller SVL (28.9–37.8 vs. 34.4–42.6 mm), smaller ratio of BW/SVL (0.11–0.20 vs. 0.15–0.22), lower ILAB (8–11 vs. 10–11), IOS (15–21 vs. 20–23), and DTAP (33–49 vs. 46– 51); from E. inunguis, E. tuelinae sp. nov., and E. safari sp. nov. by rostral scale not in contact with nostril (RNO = no); from E. tuelinae sp. nov. by ratio EE/HL (0.29–0.41 vs. 0.27– 0.36), and lower DTAP (33–49 vs. 52–62); from E. safari sp. nov. by generally lower DTAP (33–43 vs. 38–54). Furthermore, distinguished from all other analysed Ebenavia except E. safari sp. nov. by long tapering nasal process of premaxilla; from E. tuelinae sp. nov. and E. robusta sp. nov. by long premaxillary lappets of nasals; from E. safari sp. nov. by recognisable basal tubercle on basisphenoid; and from all other analysed Ebenavia except E. inunguis by a codon inser- tion of CGA (Proline) at position 438 from the 5′ primer bind- ing site of the PRLR fragment. 
CommentSynonymy: Ebenavia boettgeri Boulenger, 1885 was considered a synonym of Ebenavia inunguis by Boulenger (1887) and subsequent authors but was resurrected as a valid species by Hawlitschek et al. 2018.
