Diagnosis:
Hindák (2002):Coloniae microscopicae, liberae, gelatinosae aut indefinitae. Cellulae solitariae liberae, in muco irregulariter dispersae, elongatae, contentu, aerugineo, homogeneo, cum pseudovacuolis (aerotopis). Reproductio divisione cellularum perpendiculariter ad axem transver salem in duas partes, et disintegratione coloniarum.
Type species: Cyanocomperia africana Hindák 2002 - monospecific genus.
Descriptions:
Hindák (2002): Colonies microscopic, solitary, free, with cells placed without any order in a mucilage. Cells elongated, with aerotopes, dividing logitudinally into equal parts.
Genotype differences, molecular
data:
Reproduction strategies, life cycles, cell division:
Hindák (2002): One of the main generic diagnostic features is the longitudinal cell division into two parts, not transverse as in great majority of coccoid Cyanobacteria. Longitudinal cell division is characteristic of the genera from the group of Woronichinia-Gomphoshaeria, Snowella.

Notes to taxonomy, misinterpretations:
Hindák (2002): One of the main diagnostic features is the longitudinal cell division into two parts, not transverse as in great majority of coccoid cyanobacteria. Longitudinal cell division is characteristic of the genera from the group of Woronichinia-Gomphosphaetia, Snowella. But in the case of the new genus, the cells are displayed irregularly in the colonial mucilage (neither in the peripheral part of the colony, nor oriented towards the center as in the subfamily Gomphosphaerioideae KOMÁREK et HINDÁK 1988, see also KOMÁREK & ANAGNOSTIDIS 1998) and not attached to the end of mucilaginous stalks. Similar longitudinal division was found with Chroostipes linearis PASCHER 1914, in which cells were attached to colourless flagellate Oikonionas syncyanotica (GEITLER 1930-1932). BOURRELLY (1970) is convinced that the genus Chroostipes is a representative of the Chlorobacteria. Also according to KOMÁREK & ANAGNOSTIDIS (1998), this genus is uncertain; the authors stated that longitudinal cell division (in rod-like solitary cells) occurs in cyanoprokaryotes only in merismopedoid colonies of the genus Microcrocis RICHTER 1892.
According to the cell division in one plane, the new genus Cyanocomperia should be classified into the family Synechococcaceae KOMÁREK et ANAGNOSTIDIS 1998, subfamily Aphanothecoideae KOMÁREK et ANAGNOSTIDIS 1998 (KOMÁREK & ANAGNOSTIDIS 1998). However, if longitudinal division of cells is considered a feature occurring very rarely only in some types of cyanobacteria, another taxonomical solution (e.g. a new subfamily?) can be accepted.
