Palaemnema Selys, 1860

Forty-three species have been described in this strictly New World genus, with six known for Ecuador. However, the genus is in need of revision, and there are potentially undescribed species in Ecuador. The few references by which some species identifications can be made are Calvert (1931) and Kennedy (1938a, 1942a). Adults are mediumsized, mostly dark with small blue stripes and spots on the thorax; the abdomen varies from nearly all black to blue on the apical segments ( Figs. 54a & 54b ). Little work has been done on the biology of this genus, though all species have been found in the vicinity of small shaded streams and seepage areas.
