MP 84, BI 1, ML 98 (Figs 1 – 3, 16) ZooBank registration: urn: lsid: zoobank. org: act: 02882 C 05 - C 5 B 8 - 48 C 9 - B 796 - 0339081 B 8412.
diagnosis
Diagnosis Posterior branch of lateral ethmoid depressed (13, 0> 1), reversed in Potamarius izabalensis; posterior process of exoccipital connected to Müllerian ramus by suture (93, 0> 1). Ambiguous optimization: Posterior cranial fontanel absent (26, 1> 0), reversed in Potamarius; epiphyseal bar indistinct (28, 0> 1), reversed in Potamarius; temporal fossa absent (38, 0> 1); subvertebral process indistinct or weakly developed (78, 1> 0), reversed in Potamarius.
discussion
Remarks The total-evidence analysis brings significant results concerning the definition of limits and species composition of Sciades. The present analysis supports the hypothesis of monophyly, relationships, and species composition as defined based on previous molecular studies (Betancur-R. et al. 2007, Betancur-R. 2009). The inclusion of Old World species in Sciades (Marceniuk and Menezes 2007, Marceniuk et al. 2012), here assigned to Hexanematichthys or Pseudosciades, is interpreted as a result of morphological convergence, mainly smaller skull openings (characters 26, 28, and 93).
