Etymology: nubila: The specific epithet comes from the Latin adjective nubila, meaning cloudy. This name is used in reference to the relatively mottled appearance in some individuals of this species (Ref. 93571).

Pseudolaguvia nubila differs from congeners except for P. austrina, P. kapuri, P. spicula, P. virgulata and P. viriosa in having a deeper caudal peduncle (9.1–11.1% SL vs. 5.0–9.0) and a combination of the following characters: head width 19.7–21.0% SL, dorsal-spine length 16.4–19.3% SL, pectoral-spine length 18.1– 22.0% SL, pelvic-fin length 15.8–18.5% SL, and body depth at anus 13.9–17.1% SL. It is distinguished from P. austrina in having a mottled brown body with yellowish bands (vs. uniform pale brown body), a weakly projecting snout in which the premaxillary teeth are barely exposed (vs. a strongly projecting snout in which the premaxillary teeth are almost entirely exposed) when the mouth is closed, a larger eye (10.8–14.0% HL vs. 4.4–8.1), fewer serrations on the anterior edge of the pectoral spine (7–8 vs. 17–19), a shorter dorsal to adipose distance (13.1– 16.8% SL vs. 29.5–32.7) and longer caudal peduncle (15.7–20.2% SL vs. 8.8–14.7); and from P. kapuri in having a smooth (vs. serrated) anterior edge of the dorsal spine, a shorter adipose-fin base (14.2–15.9% SL vs. 17.1–18.9), and narrower head (19.7–21.7% SL vs. 23.4–24.0), and from P. spicula in having longer dorsal- (16.4–19.3% SL vs. 11.6–14.3) and pectoral-fin (18.1–22.0% SL vs. 15.7–17.4) spines and fewer serrations (7–8 vs. 9–15) on the anterior edge of the pectoral spine. Pseudolaguvia nubila differs from P. virgulata in having shorter dorsal- (16.4– 19.3% SL vs. 21.5–24.0) and pectoral-fin (18.1–22.0% SL vs. 28.5–29.1) spines, a smooth (vs. serrated) anterior edge of the dorsal-fin spine, the presence of pale vertical bands (vs. pale longitudinal stripes) on the flanks and the absence (vs. presence) of a pale Y-shaped marking on the dorsal surface of the head and supraoccipital process, and from P. viriosa in having shorter dorsal- (16.4–19.3% SL vs. 23.4–29.0) and pectoral-fin (18.1–22.0% SL vs. 26.9– 32.9) spines.
