Little Featherleg

Synonyms:

  • scientific: Platycnemis sikassoensis

Type locality: Sikasso, Mali

Diagnosis

Male differs from other African Copera species by (a) favouring sunny rivers and streams, rather than shaded forest pools and streams; (b) smaller size, Hw 14-17 mm; (c) legs uniformly orange, rather than yellow to rufous and often darkened at joints; (d) subapical pale rings of S3-7 reduced, abdomen appearing dark, rather than pale basal and subapical rings giving abdomen an annulated effect; (e) branches of cerci short, usually only visible in caudal view, rather than long and well-visible in lateral and dorsal view.

Habitat description

Mostly rivers, but also streams, in open areas in forest, but sometimes shaded by gallery forest. Often with a sandy, soft (like muddy) and/or probably gravelly bottom. From 0 to 800 m above sea level, but mostly below 400, although possibly up to 1300.

confirmed: Benin; Côte d'Ivoire; Central African Republic; Gambia; Ghana; Liberia; Mali; Nigeria; Republic of Guinea; Sierra Leone; Togo; Uganda; NOT confirmed: Guinee-Bissau; Senegal
