A new species of Dudgeodes Sartori, 2008 (Ephemeroptera: Teloganodidae) from Thailand

Abstract

A new species of the genus Dudgeodes Sartori, 2008 is described from Thailand. It is the first representative of the genus reported from this country. The species is described based on mature nymphs. Dudgeodes romani sp. nov. differs from other species of the genus by the length of antennae; coloration of male eyes; shape of abdominal median tubercles; features of the tarsal claws, forefemora, gills and segments of the labial palps, and by chaetotaxy.

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

“…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).…”

“…Head surface has few forked short thick setae and short thin setae. Like other Dudgeodes species, all species have outer margin of head fringed with a row of short, basally forked setae from the area in front of eyes to the labrum insertion (Martynov et al 2016: fig. 3).…”

“…The small mayfly family Teloganodidae (Allen 1965) is recorded from Afrotropical to Oriental realms and encompasses 9 genera and 25 species (Barber-James et al 2008, Selvakumar et al 2014, Anbalagan et al 2015, Martynov et al 2016. The most speciose genus, Dudgeodes Sartori, 2008 currently has nine species: D. bharathidasani Anbalagan, 2015 (India), D. celebensis Sartori, 2008 (Sulawesi), D. hutanis Sartori, 2008 (Borneo), D. lugens (Navás, 1933) (China), D. palnius Selvakumar, Sivamarakrishnan & Jacobus, 2014 (India), D. pescadori Sartori, 2008 (Philippines), D. romani Martynov, Palatov & Boonsoong, 2016 (Thailand), D. stephani Sartori, 2008 (Borneo), and D. ulmeri Sartori, 2008 (Java, Sumatra).…”

“…Despite the notable diversity of the Philippine archipelago, only Dudgeodes pescadori from Luzon island has been reported. Given the current distribution and ecological information (Martynov et al 2016), there is a high probability that the genus is present across the entire country. Most biomonitoring studies in the country used identification keys that are not suitable for the Philippine archipelago; hence it is likely that Teloganodidae and genus Dudgeodes were reported under the family name Ephemerellidae before (Flores and Zafaralla 2012).…”

Distribution extension of Oriental mayfly Clypeocaenis oligosetosa Soldán, 1983 (Ephemeroptera: Caenidae)

“…The species develops in quite a wide temperature range from 37.7 °C/22.7 °C (day/night water temperature at the sampling place in South Vietnam, according to Soldán 1983) to 21 °C/18 °C (day/night water temperature at the sampling place of collection in northern Thailand). In northern Thailand, C. oligosetosa was found together with other Pannota species -Dudgeodes romani Martynov, Palatov & Boonsoong, 2016 (Teloganodidae) (Martynov et al 2016, original data).…”
