The synonymy of Parasesarma foresti (Rahayu & Davie, 2002) with P. indiarum (Tweedie, 1940) (Decapoda, Brachyura, Sesarmidae)

Abstract Two Southeast Asian species of Parasesarma De Man, 1895, P. indiarum (Tweedie, 1940) and P. foresti (Rahayu & Davie, 2002), have been reported to be morphologically and genetically very similar. Present comparisons of a range of material show the two species to be identical in male chelar dactylar tuberculation, pleon, and first gonopod characters, all typically used to separate close sibling species in this genus. CO1 genetic distances between the two putative species are also too low to be regarded as interspecific. Parasesarma foresti is thus here regarded as a junior subjective synonym of P. indiarum.

AbstractA challenge for taxonomists all over the world and across all taxonomic groups is recognizing and delimiting species, and cryptic species are even more challenging. However, an accurate identification is fundamental for all biological studies from ecology to conversation biology. We used a multidisciplinary approach including genetics as well as morphological and ecological data to assess if an easily recognizable, widely distributed and euryoecious mite taxon represents one and the same species. According to phylogenetic (based on mitochondrial and nuclear genes) and species delimitation analyses, five distinct putative species were detected and supported by high genetic distances. These genetic lineages correlate well with ecological data, and each species could be associated to its own (micro)habitat. Subsequently, slight morphological differences were found and provide additional evidence that five different species occur in Central and Southern Europe. The minuteness and the characteristic habitus of Caleremaeus monilipes tempted to neglect potential higher species diversity. This problem might concern several other “well-known” euryoecious microarthropods. Five new species of the genus Caleremaeus are described, namely Caleremaeus mentobellus sp. nov., C. lignophilus sp. nov., C. alpinus sp. nov., C. elevatus sp. nov., and C. hispanicus sp. nov. Additionally, a morphological evaluation of C. monilipes is presented.

Subjective Synonym

Re-examination of the type material of Palaemon javanicus Heller, 1862, shows that the current concept of the species is wrong. This species is in fact a senior subjective synonym of a widespread Southeast Asian species now known as Macrobrachium trompii (De Man, 1898). The species now commonly referred to as “Macrobrachium javanicum” following De Man (1879) from Southeast Asia is in fact, undescribed, and is here named Macrobrachium duri spec. nov. Macrobrachium duri spec. nov. can easily be distinguished from M. javanicum sensu stricto by the presence of a small triangular median process on the fourth thoracic sternite, possessing spinulate third to fifth pereiopods, having both second periopods covered with spines and few scattered short stiff setae, and the eggs been small and numerous. To add to the confusion, Palaemon javanicus Heller, 1862, is also synonymous with P. sundaicus Heller, 1862, and both were described by Heller (1862) in the same paper, making both names simultaneously available. As first revisors, we hereby choose P. sundaicus Heller, 1862, to have priority over P. javanicus Heller, 1862, when the two names are considered to be synonyms. Palaemon sundaicus Heller, 1862, is therefore also the senior synonym of Macrobrachium trompii (De Man, 1898).
