Based on morphological and molecular evidence, these three genera have been combined into Eleocharis, resulting in a monogeneric
tribe (Roalson and Friar 2000; Hinchliff et al.
family (Corethrellidae, Diptera) is an ancient group of small eavesdropping flies (oldest fossils are 122 million years old), which includes over 100 described species (Borkent 2008; Borkent & Grafe 2012).
The basic life history of torrent salamanders (4 species within the monogeneric
family Rhyacotritonidae) is poorly known.
Chara phytoherms commonly form in the littoral zone (Pedley 1990; Walker et al.
Although some authors have considered Abronieae to be monogeneric
(Bittrich and Kuhn, 1993), most authors have maintained two genera, Tripterocalyx and Abronia (Galloway, 1975; Spellenberg, 2003).
atheriniform family with the parasphenoid concave rather than convex, parasphenoid myodomes present; mesethmoid morphology unique, nasal septum formed by ethmoid and mesethmoid; parietals not contributing to posttemporal fossa; anterior vertebral parapophyses with lateral ridges; interdorsals absent; cleithrum dorsal enclosure absent; membrane just posterior to genital opening; and pelvic posteromedial process elongate.
I measured 14 habitat variables within 12 Colombian farms classified into four management systems at the Risaralda region of Colombia: Forests, Polygeneric Shaded coffee, Monogeneric
Shaded coffee and Sun coffee plantations.
Glaucosoma hebraicum is one of four members of the monogeneric
family Glaucosomatidae, which also includes the pearl perch (Glaucosoma scapulare) that is fished commercially and recreationally in eastern Australia (McKay, 1997).
Hereafter we apply the following nomenclature: (1) Vestimentifera are equated with Obturata and Afrenulata; (2) Frenulata are equated with Perviata and Pogonophora (sensu Jones, 1985); (3) Monilifera is a third monogeneric
dade that includes Sclerolinum; and (4) Siboglinidae refers to the dade that includes Vestimentifera, Frenulata, and Monilifera.
The most common invertebrates found were nematodes (9 specimens) and monogeneric
trematodes (3 specimens).
