Hand bone morphology is regularly used to link particular hominin species with behaviors relevant to cognitive/technological progress.
To increase the prospect of discovering new amphipod species, studying undersampled areas and benthic microhabitats are recommended. Amphipods thus rank amongst the least well described taxa.
This indicates that about two-thirds of amphipods remain to be discovered which is twice the proportion than for species overall. Using a nonhomogeneous renewal process model, we predicted that by the year 2100, 5,600 to 6,600 new amphipod species will be discovered.
There was no evidence of any change in papers per author or publication life-times of taxonomists over time that might have biased apparent effort. There are more authors describing species since the 1950s and fewer species described per author since the 1860s implying greater taxonomic effort and that it might be harder to find new amphipod species, respectively. Of these, 1,940 species (almost 20%) have been discovered within the last decade, including 18 fossil records for amphipods, which mostly occurred in Miocene amber and are probably all freshwater species. A key is provided to facilitate identification.Īt present amphipod crustaceans comprise 9,980 species, 1,664 genera, 444 subfamilies, and 221 families. nilotica complex’ is clarified and some species are synonymised. The position of these species in the troublesome ‘C. solamulieres Richard & Clark, 2014 are considered junior synonyms of C. brevidactyla is revalidated as the species C. Detailed re-descriptions of these four species are given as well as their geographical and ecological distributions. In the context of integrative taxonomy, both old and newly collected specimens were morphologically and genetically studied. longirostris were collected from various Indo-West Pacific localities. Recently, numerous specimens identified as C. Until now this species was thought to have a wide distribution in the Indo-Pacific region. Milne Edwards, 1837 described from specimens supposedly from La Macta River near Oran, Algeria, is an emblematic species of the ‘C.

2003 Caruso and Postel 2006 Kirsch and Geller 2006 Gross and Thapa 2012), these works are focused mainly on the medical field, especially radiology, there being as yet no manual for using these image editing tools for taxonomy, as well as for composing figures for scientific papers in the Adobe Photoshop in its current version.Ĭaridina longirostris H. 2002 Taylor 2002, Taylor 2003a, Taylor 2003b, Taylor 2003cChalazonitis et al. Although there are publications that address graphic representations through photographs (Ray 1999 Savazzi 2011), as well as editing techniques using other types of image editors (Lababede 2004a, Lababede 2004bSolomon 2009) or Adobe Photoshop (Corl et al. With the advent of new technologies to represent specimens and their structures, there are publications containing techniques that promote different means of graphic representation, mainly by illustrations (Coleman 2003(Coleman, 2006(Coleman, 2009Holzenthal 2008 Tereshkin 2013). As previously mentioned, the images presented in scientific publications are part of the results obtained by the researcher, mainly in taxonomic works, since the correct identification of the taxon depends on the description of this taxon along with good images that illustrate the diagnostic characters.
