Systematics of Indobaetis Müller-Liebenau & Morihara 1982, and related implications for some other Baetidae genera (Ephemeroptera).

Imagoes, subimagoes and eggs of Indobaetis costai Müller-Liebenau & Morihara 1982 are described for the first time; additional larval characters of I. costai and I. starmuehlneri Müller-Liebenau & Morihara 1982 are reported. A new species Indobaetis microfolius sp.n. is described based on larvae, a male subimago reared from larva and a female subimago extracted from a mature larva. Baetis michaelohubbardi (Selva-kumar et al. 2012) comb.n. is proposed for a species originally attributed to Indobaetis, based on the presence of hind protoptera, three maxillary dentisetae and other characteristics. Newly discovered diversity within the holophyletic taxon Indobaetis disproves a formerly erected idea about the close relationship of Indobaetis and the muticus-group. Thus, the senior genus-group name for the holophylum including the muticus-group is Takobia/g1; in rank-based nomenclature the names Alainites Waltz & McCafferty (in Waltz et al.) 1994 and Acerbaetis Kang & Yang (in Kang et al.) 1994 should be junior synonyms of Takobia Novikova & Kluge 1987 (new synonymy). The Neotropical taxon Caribaetis Kluge 1992 is accepted as genus (stat.n.), rather than a synonym of Fallceon, based on the original diagnosis of the subgenus Caribaetis and taking into account the significance of such character as presence of a posterior seta on the claw, shared with Indobaetis, Baetodes and some other taxa; resultant new combinations are proposed: Caribaetis planifrons (Kluge 1992) comb.n., Caribaetis alcarrazae (Kluge 1992) comb.n. and Caribaetis grandis (Gonzalez-Lazo & Salles 2007) comb.n. A new species synonymy in Fallceon is proposed, based on the presence of a hind wing costal hook in both species: Fallceon poeyi (Eaton 1995) = F. nikitai McCafferty & Lugo-Ortiz 1994 syn.n.

Revision of Ephemerythus Gillies 1960 (Ephemeroptera: Tricorythidae)

Four species of Ephemerythus Gillies 1960 are described here. Larvae, subimagoes, imagoes of both sexes and eggs of Ephemerythus niger Gillies 1960 (= E. niger ugandanus Kluge 2010 syn. n.) and Ephemerythus pictus Gillies 1960 (= E. kiboensis Gillies 1960 syn. n.) are redescribed based on reared material from their type localities (Amani in Usambara Mountains and Marangu in Kilimandjaro respectively) and from other places in Tanzania. Larvae, subimagoes, imagoes of both sexes and eggs of a new species Ephemerythus nigricolor sp. n. are described based on reared material from Zambia. The species formerly reported as «Ephemerythus sp. C» (Kluge 2010a) is described here as Ephemerythus gilliesi sp. n., based on one larva with eggs, collected by M.T. Gillies in Cameroon.
