“…The character numbers assigned in Chapleau (1993) are shown in parentheses after the title of each character, as follows. (1) exoccipitals forming ventral margin of foramen magnum, but zygapophyses not mutually attached: in Citharidae; (2) basioccipital forming ventral margin of foramen magnum: in Samaridae, Paralichthyidae, Bothidae, and Pleuronectidae (Amaoka, 1969;Sakamoto, 1984;Chapleau, 1988;Chapleau and Keast, 1988;Hoshino and Amaoka, 1998;present study). In Chapleau (1993), states (0) and (1) shown above were not distinguished, and Scophthalmidae was coded as (1) [ϭ(2) in this study].…”

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.

“…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]).…”

“…1A). Losses of this muscle must be interpreted as having occurred in separate lineages, if the monophyly of the Scophthalmidae (Hensley and Ahlstrom, 1984) or the close affinity of Tephrinectes and "Lineage IV" of Chapleau (1993) (suggested in Hoshino andAmaoka, 1998) are to be supported. 4.…”

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.

Sexual dimorphism of the flounder Bothus robinsi (Pisces: Bothidae)

The anatomical organization of the reproductive system of the flounder, Bothus robinsi, is similar to other fish in the order Pleuronectiformes. Accentuated, external secondary sexual characters are observed in males such as increased body length, larger left pectoral fin, and greater interorbital distance. As a qualitative character, the rostral spine, which is part of the maxillary bone, is pronounced. The interorbital distance implies noticeable internal sexual differences, such as the broadening of the left frontal and lateral ethmoid bones, and a greater length of the oblique muscles of both eyes, the optic nerves, and the left olfactory nerve. Five male specimens examined had female external secondary sexual characters.
