DistributionBolivia, Brazil (Acre, Amazonas, Mato Grosso, Pará, Rondônia), Colombia (Amazonas), Peru (Loreto, Madre de Dios, Pasco, Ucayali)

Type locality: “Amazonian Peru”. Restricted to “Iquitos (3°50' S 73°15' W), Loreto, Peru" by Bour and Pauler (1987:8).

maculata: Type locality: "Tropical America." Restricted to "S. America" by Gray (1873j:65); and to "Venezuela" by Boulenger (1889:219) and Pritchard and Trebbau (1984:127), in error, see Rivas et al. (2015).  
Reproductionoviparous. 
TypesHolotype: SMF 66246, see Mertens (1970) and Bour and Pauler (1987). Lectotype: BMNH 1947.3.5.92, formerly NHM 51.8.12.1; Bates collection (designated by Bour & Pauler 1987).
Holotype: NHMUK 1946.1.22.14 (formerly 1866.8.14.233), fide Bour and Pauler (1987), Rivas et al. (2015), Ettmar
(2019), and Cunha et al. (2019) [maculata] 
DiagnosisM. raniceps and M. gibba can be distinguished by the head width in relation to caparace lenght. This proportion in M. raniceps are more than 20% in adult individuals, and less than 20% in M. gibba (Rueda-Almonacid et al 2007).

Diagnosis (heliostemma). A medium- to large-sized toadhead turtle of the genus Batrachemys that is distinguished from members of other toadhead genera by its large, wide, rounded head; its narrow parietal roof and parieto-squamosal arch; its reduced neural bone series; the combination of its relatively "shallow" carapace, having a median groove, lacking a keel, absence of lateral marginal narrowing, and presence of mild lateral marginal upturning; the presence of a large antero-medial distal tibial scale; and its distinct plastral pattern.
Batrachemys heliostemma is distinguished from its congeners by its distinct head coloration; diminished size of neck tubercles; lack of horizontal line in the iris; greater parietal roof width; its carapace widest at M7; 4th vertebral scute always wider than long; 11th marginals equal to or wider than 12th; mild upturning of lateral marginals; inter-gular scute narrower than gulars; greater width of the anterior plastral lobe; its plastral seam formula; and its plastral pattern.
Among its congeners Batrachemys heliostemma is sympatric with and most similar to B. raniceps. The two forms share a relatively similar head size and shape, a pointed nose, small barbels, a similar neural bone series, a similar plastral seam formula, lack of keels, a shallow carapace groove, a well-developed distal antero-medial tibial scale, and similar plastral patterns. However, B. heliostemma sp. nov. differs from B. raniceps by having a different head pattern and coloration, a broader parietal roof, a more substantial parieto-squamosal arch, an intergular narrower than its gulars (opposite in B. raniceps), a flatter shell, and 11th pair of marginals equal or wider than 12th (equal in B. raniceps). [from MCCORD et al. 2001]. 
CommentHabitat: freshwater (rivers, swamps)

Synonymy: Partly after Fritz & Havas 2007. P. wermuthi has been synonymized with Phrynops raniceps by Bour & Pauler 1987 but considered as valid by more recent authors. 
EtymologyPhrynops wermuthi has been named in honor of Heinz Wermuth (1918-2002), German herpetologist.
