New data on trophic associations of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae) and lemurs (Primates, Lemuroidea) in Madagascar revealed by metabarcoding.

Resource use and diet specialisation of Madagascan dung beetles have been little studied especially concerning the possible associations between specific dung beetle and lemur species. Pilot studies have demonstrated that amplicon sequencing is a promising tool for the lemur inventories. In the present contribution, we report the results of the gut content analysis of three endemic Madagascan dung beetles species: (Harold), (Lebis) and (Lebis).

Dung-beetles (Coleoptera, Scarabaeidae, Aphodiinae, Scarabaeinae) feeding on faeces of steppe marmots (Rodentia, Sciuridae) in Middle Volga territory.

Background: In open terrestrial biomes of Holarctic realm, ground squirrels are recognised as keystone species inhabiting steppes. They shape the plant species composition and diversity and support a fauna of species associated with their burrows. Ground squirrels and associated dung-beetles are important elements of the steppe food webs, yet the trophic associations between species are still poorly studied.

Amplicon metagenomics of dung beetles (Coleoptera, Scarabaeidae, Scarabaeinae) as a proxy for lemur (Primates, Lemuroidea) studies in Madagascar.

Dung beetles (Scarabaeidae, Scarabaeinae) are among the most cost-effective and informative biodiversity indicator groups, conveying rich information about the status of habitats and faunas of an area. Yet their use for monitoring the mammal species, that are the main providers of the food for the dung beetles, has only recently been recognized. In the present work, we studied the diet of four endemic Madagascan dung beetles ( (Fairmaire), (Harold), (Boucomont), and Fairmaire) using high-throughput sequencing and amplicon metagenomics.

A new species of the endemic Madagascan scarab beetle genus, Madecorphnus grebennikovi (Coleoptera: Scarabaeidae: Orphninae): morphological description and DNA barcode.

A new species of the orphnine scarab beetle genus Madecorphnus Paulian, 1992, Madecorphnus grebennikovi Frolov, Akhmetova Vishnevskaya, new species, is described from the Marojejy National Park, Sava Region, northeastern Madagascar. The new species can be distinguished from the congeners by the parameres narrowly rounded in lateral view and having a small but distinct lateral teeth, and by the endophallic armature consisting of 1) a long straight sclerite with attached to its end a 2/3 shorted, somewhat curved sclerite, 2) separate smaller, elongate sclerite, and 3) a rather large area of microspinules. The 811 bp long fragment of the mitochondrial gene COI (DNA barcode) is provided as a part of the diagnosis of the new species.

The taxonomic status of Aphodius insperatus Petrovitz, A. longipennis Rakovič and A. inylchekensis Frolov (Coleoptera: Scarabaeidae: Aphodiinae).
