Wahlberg, Emma, Espeland, Marianne & Johanson, Kjell Arne, 2014, Seven new species of Chimarra (Trichoptera: Philopotamidae) from Malawi, Zootaxa 3796 (3), pp. 579-593 : 581

Genus Chimarra Stephens 1829

Type species: Phryganea marginata Linnaeus 1767: 910 .

Diagnosis. The adults of the species in the genus Chimarra are distinguished from those in other philopotamid genera by having a spur formula of 1,4,4 and hind wings with vein A2 looped to form a closed cell ( Blahnik 1998). Within Chimarra the subgenus Chimarra Stephens 1829 has a worldwide distribution, while Chimarrita Blahnik 1997 , Otarrha Blahnik 2002 , and Curgia ( Walker 1860) are restricted to the Neotropical region with a few species of Curgia represented in the southern Nearctic region. Although 83 species of Chimarra have been reported from the Afrotropical Region (Morse 2103), species in the genus have never previously been recorded from Malawi, and from the neighbouring countries only three species are known, one species from each of Tanzania, Zambia and Mozambique.
