Tatocnemis is the sole genus of damselflies in the family Tatocnemididae, one of three families in the superfamily Tatocnemidoidea.[3][4] The genus occurs on Madagascar and neighbouring islands and contains ten described species.[3]
Species of Tatocnemis inhabit forest streams and are characterised by their slender bodies, wings with a narrow stalk at the base, and large pterostigmata.[2] Several species have distinctive wing shapes, including wing tips with a shallow notch.[2]
Family classification
[edit]Kirby established the genus Tatocnemis in 1889 for Tatocnemis malgassica from Madagascar.[2] He considered it a highly distinctive genus because of its wing structure, noting similarities to a small number of unusual damselfly genera from the Philippines and New Guinea.[2]
In a revision of Megapodagrionidae, Rácenis (1959) established Tatocnemidinae as a new subfamily containing Tatocnemis and Archaeopodagrion.[1] Subsequent morphological and molecular studies supported recognition of this lineage as distinct from Megapodagrionidae.[5][6]
Modern classifications recognise Tatocnemididae as a separate family of damselflies. The family contains only the genus Tatocnemis and its ten described species.[4][3]
In 2026, Carter and colleagues recognised Tatocnemididae, Pentaphlebiidae and Protolestidae as the superfamily Tatocnemidoidea, based on phylogenomic studies that resolved the three families as a distinct lineage of damselflies.[7]
Species
[edit]The following species are currently placed in Tatocnemis:[3]
- Tatocnemis crenulatipennis Fraser, 1952
- Tatocnemis denticularis Aguesse, 1968
- Tatocnemis emarginatipennis Fraser, 1960
- Tatocnemis malgassica Kirby, 1889
- Tatocnemis mellisi Schmidt, 1951
- Tatocnemis micromalgassica Aguesse, 1968
- Tatocnemis olsufieffi Schmidt, 1951
- Tatocnemis robinsoni Schmidt, 1951
- Tatocnemis sinuatipennis (Selys, 1891)
- Tatocnemis virginiae Legrand, 1992
Etymology
[edit]The family name Tatocnemididae is derived from the type genus Tatocnemis, with the standard zoological family suffix -idae.
The genus name Tatocnemis is of uncertain derivation. The suffix -cnemis is from the Greek κνήμη (knēmē, "leg" or "shin"), a component used in several related damselfly genus names such as Priocnemis and Idiocnemis. Kirby did not explain the origin of the prefix Tato- when he established the genus in 1889.[2][8]
