The species evanescens appears isolated from rosaceus in having apomorphy of first gonocoxae with proximal angle concave in contrast to rounded in rosaceus and parameral second tooth truncated in contrast to beak like in rosaceus.
In this context, it is important to note that Coddington (1988) defines an adaptation as an apomorphy arising through natural selection that appears to have some advantageous selective value when compared to the plesiomorphic condition.
In all of these instances, fiber dimorphism is probably an apomorphy.
Recent studies of 29 actinopterygian and 90 sarcopterygian genomes revealed that the AQP2, -5, or -6 gene clusters represent a genomic apomorphy since they are only found in the lobe-finned fish lineage (Sarcopterygii), including tetrapods that secondarily adapted to the aquatic environment (Cerda and Finn, 2010; Tingaud-Sequeira et al.
A distinctive apomorphy of Distega is the continuous suture that divides the upper and lower halves of the mesepisternum (Fig.
However, assignment of [dagger]perfecta to this taxon is also supported by the very long CuPb, reaching the posterior wing margin distal to the second third of wing length, which is a putative apomorphy.
COMPARISON WITH SIMILAR GENERA: The highly elevated labrum is a peculiar apomorphy of the new genus which only occurs in very few genera of Plataspidae, and is also exceptional in other heteropteran families.
The apomorphy of paramere stout, dorsal side flat with apically setose stem and pygophores with sharp edge, medially concave with two tubercles at sides, species with clearly red and white pattern closely relate it with, flavidus, nigrofasciatus, ortus, and superstitiosus.
Coddington (1990), for example, argued that "transformation" of one structure into another (one step) was, in general, a more parsimonious and efficient explanation than complete loss of a plesiomorphic feature and gain of an apomorphy (two steps).
HGR ecotype was fixed for genotype 29, which was the most abundant in all lakes surveyed while 85% of LGR ecotype possessed genotype 31, derived from 29 by a single apomorphy and not observed elsewhere.
Among Apini, vivid metallic colors are usually considered an apomorphy of Euglossina (Oliveira, 2006).
Acrossota is, however, unique among octocorals in lacking pinnules on the tentacles (Alderslade and McFadden, 2007), an apomorphy that is not shared with clavulariid sp.
Rami large, sloping backwards, encircling the aedeagus, with paired, melanized, laterally directed, pointed processes protruding from the ectophallic membrane inside theventrolateral lobes (apparently an apomorphy of genus) (Fig.
