Based on the examination of the type series of Cloe tristis Hagen, 1858 (type species of the genus Teloganodes Eaton, 1882) and material housed in several institutions, a revision of Oriental Teloganodidae is proposed. A lectotype is designated for Teloganodes tristis (Hagen, 1858) and the genus is redefined. The species T. major Eaton, 1884, is a subjective junior synonym of T. tristis Hagen, 1858 (syn. nov.). The genus Macafertiella Wang, 1996 is a subjective junior synonym of Teloganodes Eaton, 1882 (syn. nov.). A phylogenetic analysis is performed on all available nymphs. Teloganodes is restricted to Sri Lanka and the Western Ghats of India and encompasses the type species and T. dentatus Navás, 1931, T. insignis (Wang & McCafferty, 1996) (comb. nov.), and the following new species: T. tuberculatus sp. nov. (Sri Lanka), T. kodai sp. nov. (India), T. jacobusi sp. nov. (Sri Lanka) and T. hubbardi sp. nov. (Sri Lanka). The type material of T. dentata is redescribed. Species from Southeast Asia are assigned to two new genera. Dudgeodes gen. nov. includes the type species D. pescadori sp. nov. (Philippines) and D. lugens (Navás, 1933) comb. nov. (China), D. hutanis sp. nov. (Borneo), D. stephani sp. nov. (Borneo), D. ulmeri sp. nov. (Java, Sumatra), and D. celebensis sp. nov. (Sulawesi). The genus Derlethina gen. nov. is established for D. eloisae sp. nov. (Borneo). The egg morphology is presented for the first time for the family Teloganodidae. Affinities within the family and between related families are discussed and a key to distinguish all species known at the larval stage is proposed.

The adult habits and emergence of Dolania americana (Ephemeroptera: Behningiidae) were studied at the Blackwater River in Northwestern Florida. The adult life is crepuscular, beginning about 1½ hrs before sunrise with emergence of male subimagos. Males molt to imagos, female subimagos emerge, males and females mate, and females begin to oviposit in a fairly precise time sequence over the following hour. Only a few adults survive past sunrise. Females never molt to imagos and are polymorphic. Emergence is seasonal and begins between the end of April and the middle of May, depending on climatic conditions. Emergence is photoperiodically entrained. Water temperature is a phase setter and light intensity acts as a synchronizer.

The seventh in a series on the Leptophlebiidae O^phemeroptera) of New Caledonia, this papers treats three new genera (Paraluma, Oumas, and Amoa) and 12 new species. For Paraluma gen.n., the type species P. cancellata sp.n., P. triangularis sp.n., P. gilva sp.n. and P. minuta sp.n. are described from male and female imagos and nymphs, P. pulla sp.n. from male imagos and nymphs, and P. maculata sp.n. from male and female imagos. For Amoa gen.n., the type species A. fronini sp.n., A. subsolano sp.n. and A. orthogonia sp.n. are described from male and female imagos and nymphs, A. cressonensis sp.n. from nymphs only and A. hebes sp:n. from the male imago only. Oumas orbis gen.n. sp.n. is described from male and female imagos and nymphs.

Pour Amoa n. gen., l'espèce-type A. frontoni n. sp., A. subsolana n. sp., A. orthogonia n. sp. sont décrites à partir d'imagos mâles et femelles et de larves, A. cressonensis n. sp. à partir de larves seulement et A. hebes à partir d'une imago mâle seule. Oumas orbis n. gen. n. sp. est décrite à partir d'imagos mâles et femelles et de larves.
