“…This characteristic may be another synapomorphy of this clade, or may support proposed affinities with "Lineage IV" of Tephrinectes (Hoshino and Amaoka, 1998), which has 16 "principal rays" (Fig. 6, Table 2), and the paralichthodid Paralichthodes (see Cooper and Chapleau, 1998a), which has 16 or fewer "principal rays" (16 rays in total, 6 branched and 2 segmented rays in each lobe [Sakamoto, 1984: not examined in this study]). Sixteen "principal rays" in the Achiropsettidae suggest an affinity of this family with "Lineage IV" (see following).…”

Descriptions of pleuronectiform caudal fin rays, which vary considerably in composition, have been based on phenotypes (branched, segmented, and unsegmented). To provide a more precise background to the phylogeny, the homologies of the caudal fin rays are considered. The distinction between "principal rays" and "procurrent rays," determined from their correspondence with those of generalized percomorphs, is adopted. Also, the composition of these rays and their associated muscles are compared within the pleuronectiforms. Estimated "principal ray" numbers are 17 (Psettodidae, Citharidae, Paralichthyidae, Bothidae), 15-18 (Scophthalmidae), 16-23 (Pleuronectidae), and fewer than 17 (Tephrinectes, Poecilopsettidae, Rhombosoleidae, Samaridae, Achiropsettidae, Achiridae, Soleidae, Cynoglossidae). The number of "procurrent rays" in each lobe are 3 or 4 (Psettodidae), 3 (Citharoides, Paracitharus, Lepidoblepharon [Citharidae]), 2 (Citharus, Brachypleura [Citharidae], Tephrinectes, Poecilopsettidae, Soleidae), 1 (Pleuronectidae, Rhombosoleidae, Samaridae, Achiropsettidae), 1 or absent (Scophthalmidae, Paralichthyidae), or consistently absent (Bothidae, Achiridae, Cynoglossidae). New characters of potential usefulness in phylogenetic consideration of the Pleuronectiformes, including the hypochordal longitudinalis, interradialis between the outermost "principal" and medialmost "procurrent rays" and "pseudo-interradialis" (newly identified muscle), are proposed and their phylogenetic significance considered.

“…Monophyly of Citharidae and status of subordinate subfamilies. Previous authors (Amaoka, 1972;Hensley and Ahlstrom, 1984;Aboussouan, 1988;Chapleau, 1993;Nelson, 1994;Evseenko, 1996;Hensley, 1997;Cooper and Chapleau, 1998a) have doubted the monophyly of the Citharidae, mainly because apparent synapomorphies for the family had not been established. However, in the present study, newly determined characters appeared to represent synapomorphies of the Citharidae, thus supporting the monophyly of the family (Fig.…”

The monophyly of Citharidae, the pleuronectoid family thought to be a transitional group between the Psettodoidei and other typical pleuronectoids, has been in question mainly because of the lack of recognized synapomorphies for the family. In this study, the citharid skeleton is described, and the monophyly of the family and its phylogenetic position within the Pleuronectoidei are reassessed following a phylogenetic analysis based on 45 osteological, myological, and external characters. The Citharidae was found to represent a monophyletic group, supported by six synapomorphies (e.g., first dorsal proximal radials firmly wedged into notch of blind side lateral ethmoid; anterior dorsal proximal radials tightly mutually attached; blind side posterior nostril considerably enlarged). Two previously recognized subfamilies, sinistral Citharinae and dextral Brachypleurinae, are invalid because of their nonmonophylies. Interrelationships of the pleuronectoids shown herein are discussed.

“…A total of 33 sequences from 30 species pertaining to seven of the thirteen families defined morphologically in this order (Chapleau, 1993;Cooper and Chapleau, 1998), were analyzed (Table 1). Most species were sampled in the Atlantic Ocean on the Galician (NW Spain) and Brazilian coasts, the rest of the samples were collected in the Cantabric Sea and Indian Ocean.…”

“…In addition, this author proposed the existence of twelve families, suggesting that the subfamilies Achirinae Pleuronectinae, Poecilopsettinae, Rhombosoleidae and Samarinae should be elevated to the rank of family. More recently, Cooper and Chapleau (1998), also included the family Paralichthodidae which comprises Paralichthodes algoensis, a problematic species previously classified within Samarinae. However, the relationships among the families of the order would not change, being essentially those proposed by Lauder and Liem (1983), including the poor resolution in the suborder Pleuronectoidei due to the large number of polytomies.…”
