Fig. 2. Cretapsaraathanata Luquegen. etsp. nov. from Burmeseamber. (A to G) Detailed views of Holotype LYAM-9. (A) Close-up of antero-ventralcarapace with eyes and eyestalks, antennae, and the excurrent openings beside the palps of the third maxillipeds (mxp3). (B) Close-up of dorsal carapace showing the orbits lacking orbital fissures and the anterolateral marginwith three spines including the outer orbitalspine. (C) Overview of specimenin ventral view with legs, pleon, sternum, mouthparts, eyes, andleft cheliped. (D) Close-upofleft cheliped inventral obliqueview, showingastraight dactylusandpollex, thelatter bearingsmallacuteteeth on occlusalmargin. (E) Ventral view of pereopods 2 to 5, showing all legs of similarsize and slendershape, with small, thin, spaced setae, and an acute, long dactyli. (F) Close-up of themxp3, showing the palp and the fine lining of setae in the occlusal margin, the two hollow openings beside the palp of mxp3 (white arrow), and small granulations in the pterygostome. (G) Close-up of posterior sternites and pleon tucked under the carapace, typical of a eubrachyuran.
