One new species of Indocloeon Müller-Liebenau from Brunei, I. spathasetissp. n., and one new species from Indonesia, I. timorensesp. n., are described and illustrated based on their larvae. The total number of known Indocloeon species increases from two to four and the generic attributes of the larvae are amended based on the examination of the new species. Results on the genetics of some speci...

Material collected between 1984 and 1988 in Guinea Mali 2003 2008 the Ivory Coast substantially increased our knowledge of Labiobaetis Novikova & Kluge West Africa. We identified eight different species using morphological characters. One species, L. ediai sp. nov. , is new to science; it described illustrated, based on its nymphs. The status boussoulius (Gillies, 1993) discussed diverg...

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 micha...

The male imago of Cloeodes irvingi Waltz & McCafferty, 1987 is described for the first time based on reared nymphs collected from the state of Pernambuco, northeastern Brazil. It is differentiated from Neotropical congeners, among other characteristics, by the marginal intercalary veins being paired, except between veins ICu1-ICu2 and ICu2-CuP where they are single and between Sc-R1 and CuP-A w...

Larvae, subimagoes, imagoes of both sexes and eggs of Thraulobaetodes cumminsorum Elouard & Hideux 1991 are described based on reared material from north-west of Zambia. Structure and development of genitals testify that Thraulobaetodes Elouard & Hideux 1991 belongs to Rhithrocloeoninae Kluge 2012. According to the newly suggested classification, Rhithrocloeoninae are divided into Thraulobaetod...

We reared Cloeon dipterum from egg hatch to adult at 10 constant temperatures (12.1–33.57C) to test 3 hypotheses (thermal equilibrium hypothesis, temperature size rule [TSR], and O2and capacity-limited thermal tolerance [OCLTT]) that account for variation in life-history traits across thermal gradients. Male and female adult size declined ~67 and 78% and larval development time declined ~88% wi...
