“…Several studies have been published recently on the phylogeny of Osteoglossoidei suborder using morphological data [ 11 ], partial mitochondrial sequences [ 38 ], a few nuclear genes [ 39 ] or the combination of the latter two [ 40 ]. On the other hand, there is only a single study that analysed the phylogenetic relationship of the osteoglossids based on all genes present in the mitochondrial genomes [ 41 ] but the Asian arowana was not included as its complete mitogenomic sequence was not available.…”

Background: Mitochondrial DNA-derived sequences have become popular markers for evolutionary studies, as their comparison may yield significant insights into the evolution of both the organisms and their genomes. From the more than 24,000 teleost species, only 254 complete mtDNA sequences are available (GenBank status on 06 Sep 2006). In this paper, we report the complete mitochondrial genome sequence of Asian arowana, a basal bonytongue fish species, which belongs to the order of Osteoglossiformes.

“…(1998) supported a close relationship between an eel and an osteoglossomorph ( Pantodon ) – no mention is made of the other osteoglossomorphs included in their analysis or that the only relationship between Anguilla and Pantodon was based on symplesiomorphy. Al‐Mahrouki et al . 's (2001) analysis of the sequences of preproinsulin cDNAs from five osteoglossomorphs ( Osteoglossum , Pantodon , Hiodon , Chitala and Gnathonemus ), however, seems more straightforward, although no discussion beyond ‘maximum parsimony’ was made of their methods of phylogenetic analysis.…”

“…This larger group was in turn the sister group of (zebrafish (common carp + white sucker)). Although I am not discounting the value of this data being applied to phylogenetic questions, I am skeptical about Al‐Mahrouki et al . 's (2001: 57) suggestion that their data have helped in ‘resolving the debate over the position of osteoglossomorphs within teleosts’, for two reasons.…”

Several recent studies using analyses of morphological characters have addressed the interrelationships of Osteoglossomorpha, a group that sometimes is considered the living sister group of all other living teleosts. Many characters used in these studies were found to be poorly defined, to be coded incorrectly or illogically, or to display more variation than was described. The goal of this study is to address these concerns and contribute generally to knowledge of the morphology and systematic relationships of osteoglossomorphs. Analysis of 72 characters (65 informative) scored for 20 genera resulted in two most parsimonious cladograms (171 steps, CI = 0.6433, CI = 0.6139 excluding uninformative characters, HI = 0.3977, HI = 0.3861 excluding uninformative characters; RI = 0.7782; RC = 0.5006). Osteoglossomorpha is supported by both synapomorphies and homoplasies, although its monophyly was not truly tested in this analysis (only a single outgroup, Elops , was included in the analysis). The only difference in the topologies of these cladograms is in the position of †Lycoptera (recovered as either the sister group of all other osteoglossomorphs sampled or of †Eohiodon +Hiodon ). †Ostariostoma is recovered as the sister group of all non‐hiodontiform osteoglossomorphs. Mormyrids are the sister group of notopterids + osteoglossids. This clade has not been found in other recent analyses. Mormyrids and notopterids usually are considered more closely related to each other than to any other group; characters not included here support this relationship and future consideration of these characters must be made. Although almost completely dichotomous, many nodes of the resulting trees lack rigorous support. For example, †Palaeonotopterus is interpreted as the sister group of all mormyrids sampled, although for this taxon only 22% of characters could be scored. © 2003 The Linnean Society of London.

“…This group of fishes has also attracted the attention of molecular biologists. Consequently, molecular systematic studies of the group have increased rapidly (Kumazawa & Nishida, 2000;Lavoué et al, 2000;Al-Mahrouki et al, 2001;Lavoué & Sullivan, 2004).…”

Redescription of †Paralycoptera wuiChang & Chou, 1977 (Teleostei: Osteoglossoidei) from the Early Cretaceous of eastern China

from the Early Cretaceous of China is redescribed herein through a re-examination of the original materials, as well as observations on some newly collected specimens. The use of the peeling method has revealed much of the new or revised information on its osteology, e.g. aspects of the nasal, infraorbitals, retroarticular, preopercle, extrascapular, basihyal toothplate, epineural, pelvic fin, caudal skeleton and scales. The phylogenetic relationships of †Paralycoptera and other osteoglossomorphs are re-evaluated. The cladistic analysis largely agrees with the previous hypothesis that †Paralycoptera is not a †lycopterid, but rather a stem osteoglossoid. †Paralycoptera is excluded from notopteroids and exhibits the following derived characters of the Osteoglossoidei: (1) palatal area behind and below orbit completely covered by infraorbitals; (2) jaw articulation under posterior portion of orbit; (3) opercle depth twice or more its width; (4) first pectoral fin ray much enlarged and long, extending posteriorly beyond origin of pelvic fin. †Singida and †Phareodus are regarded as different levels of osteoglossoids above †Paralycoptera. †Singida shares the following derived characters with †Phareodus plus extant osteoglossoids: (1) jaw articulation posterior to orbit; (2) anterior process of hyomandibula in contact with entopterygoid; (3) subopercle small and anterior to opercle. †Phareodus shares the following derived characters with extant osteoglossoids: (1) supraorbital and otic sensory canals connected; (2) one uroneural; (3) reticulate furrows present over entire scale.
