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.
cariba seems to be an apomorphy. To avoid any possibility of misclassification of the chromosome type, the index (L/S) was determined for 30 pairs of the chromosomes NO 20 from different individuals, finding that the centromeric index was always, within the SM range.
The phylogenetic species concept (sensu Mishler and Theroit): monophyly, apomorphy, and phylogenetic species concepts, pp.
The subopercle character, at least, is a probable apomorphy of these three species suggesting that O.
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.
The presence of laticifers in Caricaceae is clearly an apomorphy; laticifers are unknown elsewhere in Brassicales.
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., 2010; Finn and Cerda, 2011; Xu et al., 2013; Finn et al., 2014).
This seems to be an apomorphy for the genus Kerodon, once all other studied Caviidae show 2n=64: Cavia (Gava et al., 1998), Galea (Maia, 1984), Dolichotls (Wurstler et al., 1971) and Hydrochoerus (Saez et al., 1971; Caldera, 2005).
As for the 5S rDNA, it is not possible to determine whether multiple pairs bearing 5S rDNA sites are an ancestral condition for the genus or an apomorphy for the analyzed species.
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. I found no character that could reject the hypothesis that [dagger]perfecta belongs to Agryllacris.
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.
