HL 28.2-31.6% of SL; ED 3.1-3.5; FO 4.2-5.0; BD 44.6-46.2; SN 5.8-6.6; IO 2.6-3.5; UJ 12.4-14.0; CP 11.0-12.3; P1L 12.1-14.6; P2L 6.2-8.4; DH 11.7-14.1; AH 11.0-13.7.
Body elliptical and well depressed, body depth 2.2-2.4 times in SL. Head large, 3.2-3.6 times in SL. Snout Slightly larger than eye diameter. Upper profile of head slightly concave. Eye small, 7-8 times in head, upper eye slightly anterior to lower eye. Mouth oblique, large, posterior margin of upper jaw reaching posterior margin of lower eye. Lower jaw not projected. Small uniserial caniniform teeth on both jaws, anterior teeth larger and stronger than posterior teeth. Gill-rakers long, slender. Pseudobranchiae present. Nostrils on ocular side small; anterior nostril round with a flap posteriorly, posterior nostril oval without flap. Nostrils on blind side small, situated near dorsal margin; anterior nostril round with a flap posteriorly and posterior nostril round. Interorbital region fairly flat and narrow, its width shorter than eye diameter. Dorsal fin originating above middle of upper eye. Pectoral fins small, about half of head on ocular side, about one-third of head on blind side. Pelvic fins on both sides subequal. Caudal fin double truncate.

Distribution:
Coast of Chile.
Remarks:
In the position of the dorsal fin origin P. microps approaches some of the species of Hippoglossina, but the form of the teeth and the absence of an anal spine suggest that it belongs to Paralichthys (Norman, 1943).
