A revision of Oriental Teloganodidae (Insecta, Ephemeroptera, Ephemerelloidea)

Abstract

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.

Integrative taxonomy of the genus Dudgeodes Sartori, 2008 (Insecta, Ephemeroptera, Teloganodidae) from the Philippines with description of new species and supplementary descriptions of Southeast Asian species

“…As reported in Sartori et al 2008, the antenna length relative to the head width also varies between species. While most Philippine species reported here have an antenna length subequal to the head width, in Dudgeodes luntian sp.…”

“…Paratypes of other Southeast Asian species of Dudgeodes deposited in the Museum of Zoology, Lausanne, Switzerland (MZL) were examined for morphological comparisons and supplementary descriptions. Terminologies followed Sartori et al (2008) and Martynov et al (2016).…”

On the validity of Epeorella Ulmer, 1939 (Ephemeroptera, Heptageniidae) with general considerations on the Heptageniidae of the Sunda Islands

“…It has already been demonstrated that the subimaginal stage may retain some nymphal structures, such as gill sockets (Sartori et al 2008), which may help to link nymphal and winged stages. The presence of vestigial tubercles on the terga thus indicates that the nymph possesses a median single ridge on the abdomen.…”

An updated list of type material of Ephemeroptera Hyatt & Arms, 1890, deposited at the Zoological Museum of Hamburg (ZMH)

“…In addition to Ulmer’s collection, the ZMH also stores primary type material described by other authors, such as Klapalek (1905a,b), Lestage (1930, 1935), Malzacher (1976, 2015, 2016), Müller-Liebenau (1971, 1974, 1980a, b, 1981), and Sartori (2008, 2014e). An interesting finding was the discovery of several paratypes of species described by Esben-Petersen (e.g.…”

“…Peters and Edmunds 1972; Puthz 1977; Braasch and Soldán 1986; Campbell and Suter 1988; Gillies 1990; Grant and Peters 1993; McCafferty and Waltz 1995; Lugo-Ortiz and McCafferty 1996, 1999; Sartori et al 2008; Sartori 2014a, b, c. ).…”
