Mascarene Archipelago

Many regions of the world remain unexplored in terms of the tardigrade diversity, and the islands of the Indian Ocean are no exception. In this work, we report four species of the family Echiniscidae representing three genera from Mauritius, the second largest island in the Mascarene Archipelago. Two species belong in the genus Echiniscus: Echiniscus perarmatus Murray, 1907, a pantropical species, and one new species: Echiniscus insularissp. nov., one of the smallest members of the spinulosus group and the entire genus, being particularly interesting due to the presence of males and supernumerary teeth-like spicules along the margins of the dorsal plates. The new species most closely resembles Echiniscus tropicalis Binda & Pilato, 1995, for which we present extensive multipopulation data and greatly extend its distribution eastwards towards islands of Southeast Asia. Pseudechiniscus (Meridioniscus) mascarenensissp. nov. is a typical member of the subgenus with elongated (dactyloid) cephalic papillae and the pseudosegmental plate IV’ with reduced posterior projections in males. Finally, a Bryodelphax specimen is also recorded. The assemblage of both presumably endemic and widely distributed tardigrade species in Mauritius fits the recent emerging biogeographic patterns for this group of micrometazoans.

Following a previous revision of species of the genus Mixaderus Collado & Alonso-Zarazaga, 1996 (Coleoptera: Aderidae) from Madagascar and the Mascarene islands, I describe here six new species from the same genus from La Réunion and Mauritius: Mixaderus reunionensis n. sp.; Mixaderus chassaini n. sp.; Mixaderus lemagneni n. sp.; Mixaderus tamisieri n. sp.; Mixaderus voisini n. sp.; Mixaderus mauritiensis n. sp. I also provide an updated key to the Mixaderus species from the Mascarene archipelago.

Mascarene Archipelago

Madagascar is a major centre of diversity for the leaf-succulent genus Aloe Linnaeus (1753: 319) accounting for roughly a third of Aloe species (Carter et al. 2011). Approximately 128 species and 161 taxa are known from the region and all are restricted to Madagascar (Rakotoarisoa et al. 2014) and/or the nearby Mascarene archipelago. New taxa are described from these islands at a rate that rivals the ongoing discovery of aloes elsewhere in their natural range, on the African continent or Arabian Peninsula (Crouch et al. 2013). Extinction risks are alarmingly high among species of Aloe in this region. Conservatively, 39% of species are known to be threatened, and this figure is likely to be significantly higher (Rakotoarisoa et al. 2014), since several species have not been observed or collected for many decades. The Kew Madagascar Conservation Centre (KMCC) aims to record and collect the rare and threatened flora of Madagascar to ensure its conservation, and the genus Aloe is a priority for the dryland programme.

AbstractBulbothrix johannis is described as new to science. The species is morphologically similar to the South American Bulbothrix pseudofungicola Benatti & Marcelli but has wider lobes, laminal ciliate isidia which frequently develop into phyllidia, larger cilia and rhizines, and longer ascospores. This epiphytic species occurs fairly frequently in the cloud forests and montane thickets on Réunion Island (Mascarene archipelago). The comparison of B. johannis with morphologically and chemically similar species shows that several different African taxa are currently grouped under the widely used but problematic name B. suffixa (Stirt.) Hale.

Mascarene Archipelago

We report here a new species belonging to Nephus (Nephus) Mulsant. Nephus (Nephus) apoloniasp. nov. was collected in the Reunion Island (Mascarene Archipelago, Indian Ocean). We describe this new species and redescribe and illustrate three other Nephus species already known from Reunion: Nephus (Nephus) oblongosignatus Mulsant, 1850, Nephus (Geminosipho) reunioni (Fürsch, 1974) and Nephus (Nephus) voeltzkowi Weise, 1910. Furthermore, we present a phylogenetic tree for these four species and calculate the genetic distances between them, using high-throughput DNA sequencing of the mitochondrial genome. The similar external morphology of N. apoloniasp. nov. and N. voeltzkowi very probably explains why individuals from the first species have been mistakenly identified as the latter and were not recognized as different until now. Other than external and genitalia traits, the present study provides molecular evidence confirming these are indeed two different species.
