FIGURE 2 in Phylogenetic placement of the European sand gobies in Gobionellidae and characterization of gobionellid lineages (Gobiiformes: Gobioidei)

FIGURE 2. Cleared and stained suspensoria for representatives of Gobiidae and Gobionellidae. A = anguloarticular; D = dentary; E = ectopterygoid; H = hyomandibula; IO = interopercle; M = metapterygoid; MA = maxilla; O = opercle; P = palatine; PM = premaxilla; PO = preopercle; Q = quadrate; S = symplectic; SO = subopercle. Black arrows indicate dorsal extent of ectopterygoid; white arrows indicate ventral extent of palatine. A) Gobiidae: Microgobius gulosus UMMZ 158862; B) Mugilogobius lineage: Pomatoschistus minutus LACM 38466-2; C) Mugilogobius lineage: Chlamydogobius ranunculus LACM 44624-1; D) Stenogobius lineage: Gnatholepis anjerensis LACM 55960-4; E) Northern Pacific lineage: Gillichthys mirabilis LACM 42690-3; F) Periophthalmus lineage: Periopthalmus sp. LACM 38331-1. Scale bars = 1mm. Note that palatine in (B) is deflected slightly dorsally away from the ectopterygoid, in order to clearly show the extents of the bones. Normally, those bones are closely apposed to one another.
