A tiny goby, Elacatinus, enters the LRT with the mudskipper

Short one today.
Uncontroversial traditional nesting for the neon goby with another, larger goby, the mudskipper.

Elacatinus oceanops (Jordan 1904; 5cm; Figs. 1–3) is the extant neon goby from Bahamas coral. It is common in the aquariaum trade. Here in the large reptile tree (LRT, 1802+ taxa, subset Fig. 1) the neon goby nests with the mudskipper, Periophthalmus (Fig. 4). This clade is derived from the frogfish (Antennaris) clade and basal to deep-sea tripod fish (Bathypterois) and anglers (Lophius) in the LRT.

Note the absence of a lacrimal, 
exposing the palatine completely. The postorbital is also missing.
