New species of Labiobaetis Novikova & Kluge from Southeast Asia and New Guinea (Ephemeroptera, Baetidae)

Abstract

Material collected between 2006 and 2016 in Borneo, Sulawesi, and New Guinea further increased our knowledge of Labiobaetis Novikova & Kluge in these regions. Five species were previously reported from Borneo, two from Sulawesi, and 33 from New Guinea. Six new species have been identified using a combination of morphology and genetic distance (COI, Kimura 2-parameter), one species from Borneo (Brunei), one from Sulawesi, and four from New Guinea. They are described and illustrated based on their larvae and keys to the species of the relevant groups are provided. Additionally, new reports, a complementary description, and the COI sequence for L. dendrisetis Kaltenbach & Gattolliat are presented. The distribution of Labiobaetis in the Wallacea region is discussed based on the new findings. The total number of Labiobaetis species worldwide is augmented to 153.

The Adults and Eggs of the Species Labiobaetis ancoralis Shi Et Tong (Ephemeroptera: Baetidae)

“…The recent works on Labiobaetis indicate that it has a very rich species diversity (Kaltenbach and Gattolliat 2019; Kaltenbach and Gattolliat 2020; Kaltenbach et al 2021). An extreme example is that New Guinea has more than 37 species (Kaltenbach and Gattolliat 2021). However, those species are mostly described from nymphs.…”

“…The genus Labiobaetis Novikova and Kluge (1987) has an extraordinary species diversity, so far more than 153 species have been described around the world (Kaltenbach and Gattolliat 2021). Among them, at least 81 species were found in Asia (Kaltenbach et al 2020, 2021; Kaltenbach and Gattolliat 2021; Shi and Tong, 2014). However, most of them are described from nymphs only, and a similar situation is also found in China.…”
