Species groups

Four species groups are recognised within the genus Calumma (originally proposed by Glaw & Vences in 1994), some of which may be only phenetic, while others are phylogenetically supported:

Calumma furcifer species group

Contents: Calumma furcifer, C. gastrotaenia, C. marojezense, C. guillaumeti, C. andringitraense, C. glawi, C. vencesi

Species characterised by typically green body colouration, sleek body form, and generally no occipital lobes (flaps of skin posterior to the head; present only in C. glawi) and no rostral appendage (present only in males of C. furcifer).

Calumma cucullatum species group

Contents: Calumma cucullatum, C. crypticum, C. amber, C. tsaratananense, C. hafahafa, C. hilleniusi, C. peltierorum, C. malthe, C. brevicorne, C. jejy, C. tsycorne

Species characterised by distinct occipital lobes and generally a single bony rostral appendage that is larger in males than females.

Calumma nasutum species group

Contents: Calumma nasutum, C. fallax, C. gallus, C. guibei, C. boettgeri, C. linotum, C. gehringi, C. uetzi, C. lefona, C. juliae, C. vatosoa, C. vohibola, C. peyrierasi, C. roaloko

Species characterised by a soft dermal rostral appendage (generally present in males and absent in females). The following members possess occipital lobes: C. guibei, C. boettgeri, C. linotum, C. gehringi, C. uetzi, C. lefona, C. roaloko, and C. juliae. These taxa are collectively referred to as the C. guibei species complex. Occipital lobes are absent from all other species. The assignment of C. peyrierasi to this group remains a subject of uncertainty.

Calumma parsonii species group

Contents: Calumma globifer, C. ambreense, C. oshaughnessyi, C. parsonii, C. capuroni

Species characterised by large body size, males with paired rostral appendages, and some species with small occipital lobes.
