Corals from each of the three regions, although morphologically very similar, clustered weakly as separate groups (Fig. 3) suggesting slight morphological divergence is occurring between corals in the three isolated regions.
Although morphologically very similar, the cryptic species show quite different patterns of habitat use.
These animals are all of agreed 'show quality' and hence they are morphologically very similar.
The sequenced Mae Klong specimens are morphologically very similar to the lectotype of Unio foliaceus (Fig. 4a,b) and we consider them representatives of this nominal taxon.
Xenomorphia appears morphologically very similar to Xenismarus but differs in having the upper tooth of the mandible shorter than the lower tooth and in the presence of plicae.
The adult and nymphal stages of some argasid species are morphologically very similar, especially within the genus Ornithodoros (Barros-Battesti 2013).
We designed primers based on calmodulin sequences for use in singleplex and multiplex PCR assays to detect and discriminate between these two morphologically very similar species.
Although the species included in this group are morphologically very similar, they differ in their ability to produce mycotoxins and other metabolites and their taxonomical status has evolved continuously.
Consider, for example, the well-known phenomenon of sibling species, in which two or more morphologically very similar groups of organisms are nevertheless completely reproductively isolated (i.e., incapable of interbreeding).
Indeed these species are morphologically very similar.
Despite the stridulatory organs that characterize Toxoptera [50], species in this genus are morphologically very similar to Aphis.
