Moreover, many small arthropods are difficult to identify morphologically due to the absence of distinct morphological traits. Speciation, however, is not always accompanied by morphological differences 2, and consequently, reliable species delimitation is not feasible based on morphological criteria alone. Delimitation and identification of small arthropod species is mostly based on the discrimination of external morphology, because data relying on ecology, behaviour or internal characteristics for example, is difficult to gain. Cryptic species are defined as two (or more) distinct species that are erroneously classified as a single one 2. The increased availability of genetic methods in the past two decades had led to another additional discussion: those of cryptic species. The correct identification of species is the basis for studies concerning genetics, biodiversity, biogeography, or ecology, even, the definition of a species still remains a controversial topic in evolutionary biology 1. Additionally, a morphological evaluation of C. Five new species of the genus Caleremaeus are described, namely Caleremaeus mentobellus sp. This problem might concern several other “well-known” euryoecious microarthropods. The minuteness and the characteristic habitus of Caleremaeus monilipes tempted to neglect potential higher species diversity. Subsequently, slight morphological differences were found and provide additional evidence that five different species occur in Central and Southern Europe.

These genetic lineages correlate well with ecological data, and each species could be associated to its own (micro)habitat. 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. 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. However, an accurate identification is fundamental for all biological studies from ecology to conversation biology. It has however evolved over time from it's initial offering in January 1989 to the present day where it is a different beast to what was initially developed to include including support for color management and spot colors, and has a basic support for text.A challenge for taxonomists all over the world and across all taxonomic groups is recognizing and delimiting species, and cryptic species are even more challenging. There is no publicly available CDR file format specification. They concluded that actually this was innacurate and developed a bunch of tools to allow users to import CDR files into MS Office 2003. In 2007 Microsoft took exception to the CDR format wrongly blaming it for some security vulnerabilities in it's Microsoft Office suite of products. It is used as the default format from the Corel Draw application which was first developed in 1987 by Michael Bouillon and Pat Beirne who were tasked with developing a vector based illustration program that Corel could package with their desktop publishing solutions. CDR was a file format developed by the Corel Corporation and is used primarily for Vector graphic drawings.
