“…Eubleekerini includes all members of Photopectoralis and its sister group, Eubleekeria. Photopectoralis comprises P. aureus, P. bindus, P. hataii, and P. panayensis, whereas Eubleekeria is represented by E. jonesi, E. kupanensis, E. rapsoni, and E. splendens (see Kimura et al, 2005;Chakrabarty and Sparks, 2008). Although members of Eubleekeria are sexually dimorphic with respect to LO volume (the LO of males is larger than similarly sized conspecific females), via our comparative studies, we have not been able to identify any sexually dimorphic external features of the LOS in this genus.…”

Members of the leiognathid subfamily Gazzinae, comprising approximately two-thirds of ponyfish species, are sexually dimorphic with regard to features of the light organ system (LOS). In Gazzinae, the circumesophageal light organ (LO) of males is enlarged and varies in shape compared with similarly sized conspecific females. In association with male species-specific translucent external patches on the head and flank, these sexually dimorphic LO features are hypothesized to be correlated with species-specific luminescence displays. Anatomical differences in LO shape, volume, and orientation, and its association with the gas bladder and other internal structures that function in light emission, are compared to observations of luminescence displays for every major lineage within Leiognathidae. We reconstruct the character evolution of both internal and external morphological features of the LOS to investigate the evolution of LO sexual dimorphism and morphology. Both internal and external sexual dimorphism in the ponyfish LOs were recovered as most likely to have evolved in the common ancestor of Leiognathidae, and likelihood-based correlation analyses indicate that the evolution of internal and external dimorphism in males is statistically correlated. Magnetic resonance imaging technology was applied to examine the unique internal LOs of ponyfishes in situ, which provides a new metric (LO index) for comparison of LO structure across lineages.

“…E. kupanensis (Kimura andPeristiwady, 2005, in Kimura et al, 2005), E. rapsoni (Munro, 1964). DIAGNOSIS: Members of Eubleekeria are distinguished from all other leiognathids by the combination of a vermiculate dorsal flank pigmentation pattern, black markings in the membrane of the spinous dorsal fin, and the presence of chest scales.…”

“…Russell (1803) illustrated the fish that was later described as Equula splendens Cuvier, 1829 (who provided the binomial in a footnote referring to Russell's illustration), providing it with the common name ''Goomorah Karah''. REMARKS: Eubleekeria was described by Fowler (1904: 516-517) as a subgenus of Leiognathus to encompass Leiognathus splendens (Cuvier, 1829) and Leiognathus spilotus Fowler, 1904, which was later synonymized with L. splendens by Kimura et al (2005). Sparks et al (2005: fig.…”

“…Members of Eubleekeria are sexually dimorphic with respect to light-organ volume, with those of males being considerably larger than similarly sized conspecific females. Kimura et al (2005) presented the following combination of characters in their diagnosis of this group: body deep (42-60% SL); mouth protracting ventrally; jaw teeth slender, minute; lower margin of orbit above the horizontal through the gape when mouth closed; breast almost completely scaled; lateral line complete; dark blotch on top of spinous dorsal fin. Unfortunately, all of these features are more broadly distributed within Leiognathidae, and provide no diagnostic information for Eubleekeria.…”

“…The shape of the snout in Eubleekeria also appears to be unique, owing to the combination of a shorter snout length than in most leiognathids (25-30% of HL; similar to Photopectoralis bindus, and members of Gazza and Secutor) and an orbital ridge that protrudes strongly dorsally. The four species of Eubleekeria can be distinguished by squamation pattern (on the cheek, chest, and predorsal region) as well as the extent of the dark blotch on the spinous portion of the dorsal-fin membrane (see Kimura et al, 2005, for diagnostic species-level features). Figure 6 Clade G, in part: Sparks et al 2005. TYPE SPECIES: Karalla daura (Cuvier, 1829).…”

Recent phylogenetic work on ponyfishes has delimited and revealed the interrelationships of major leiognathid clades. To begin to recognize a monophyletic taxonomy for Leiognathidae we diagnose, delimit, and describe a number of ponyfish genera to reflect our current knowledge of their phylogenetic history. Equula Cuvier, 1815, is resurrected from synonymy with Leiognathus Lacepède, 1802, and comprises E. fasciata and E. longispinis. Members of Equula, the sister group to all other members of Leiognathidae, are large-bodied ponyfishes characterized by conspicuous round yellow blotches on the flank. The genus Leiognathus Lacepède, 1802, the sister group to the remaining members of Leiognathidae less Equula, is herein restricted to a clade comprising Leiognathus equulus, L. robustus, and L. striatus. The subgenus Equulites Fowler, 1904, comprising E. leuciscus, E. klunzingeri, and E. laterofenestra, is removed from synonymy with Leiognathus and is elevated to generic rank. The subgenus Eubleekeria Fowler, 1904 is removed from synonymy with Leiognathus and is likewise elevated to generic rank. Eubleekeria encompasses the ''Leiognathus'' splendens species complex, which is recovered as the sister group to Photopectoralis. To remedy the paraphyly of the remaining species placed within Leiognathus we describe a new genus, Karalla, which is recovered as the sister group to Nuchequula.
