背的軟條 (總數) : 5; 臀鰭軟條: 9; 脊椎骨: 28 - 30. Distinguished from its congeners in having a terete head and body (vs. slightly depressed body and strongly depressed head), which is easily manifested in the head width (17.1-19.1% SL vs. 19.4-24.3). Differs also from congeners in having a smaller anterior fontanel (about one third the length of the frontals vs. at least half the length), and very faint, poorly contrasting cream bands that are sometimes not present on some individuals (vs. sharp contrasting cream band on body). Differs further from other species of the genus, except Pseudolaguvia ribeiroi, in having a shorter adipose-fin base (11.5-13.0% SL vs. 14.8-24.0), and, except Pseudolaguvia foveolata, in having the unculiferous ridges on the thoracic adhesive apparatus joined at their posterior ends (vs. separate). Differs further from Pseudolaguvia foveolata in having fewer vertebrae (28-30 vs. 33) and a longer thoracic adhesive apparatus, extending to midway between bases of last pectoral-fin ray and first pelvic-fin ray (vs. to middle of pectoral-fin base), from Pseudolaguvia inormata in having a slender body (12.1-13.8% SL vs. 13.9-16.1) and smaller eye (8.6-11.7% HL vs. 12.7-14.9), from P. kapuri in having shorter pelvic fin (not reaching base of the first anal-fin ray vs. reaching; 13.0-14.7% SL vs. 15.3-17.9), and from Pseudolaguvia muricata in having shorter dorsal and pectoral spines (17.3-18.7% SL vs. 21.2-26.7 and 20.2-24.3% SL vs. 26.8-35.7 respectively) and a smaller eye (8.6-11.7% HL vs. 11.4-15.1). Can be distinguished further from Pseudolaguvia ribeiroi in having less distinct mesethmoid cornua, from Pseudolaguvia shawi in having a longer dorsal spine (17.3-18.7% SL vs. 13.4-16.7), and from Pseudolaguvia tenebricosa and Pseudolaguvia tuberculata in having a more slender caudal peduncle (6.9-7.8% SL vs. 7.6-9.0) (Ref. 58769).
與它的同類區分在有一個方面，圓柱形的頭部與身體 (vs. 有些扁平的身體與強烈地扁平的頭部), 容易地是在頭部寬度方面顯示.(17.1-19.1% SL vs.19.4-24.3) 在有一個方面也不同於同類比較小的前面囟門 (大約三分之一額骨的長度和至少比較一半的長度), 與非常模糊的, 貧乏地對比乳黃色的條紋有時那是不位於一些個體之上.(vs. 銳利的對比乳黃色的條紋在身體上) 除了 Pseudolaguvia ribeiroi 以外, 進一步不同於其他種的本屬, 在有一個方面較短的脂鰭基底 (11.5-13.0% SL vs.14.8-24.0), 與, 除 Pseudolaguvia foveolata, 在他們的後端被參加的胸廓的黏著器官上有 unculiferous 脊.(vs. 分開) 不同進一步從 Pseudolaguvia foveolata 有較少的脊椎骨 (28-30 vs.33) 與被延伸至在最後胸鰭鰭條與第一個腹鰭鰭條 (vs. 對胸鰭基底的中央) 的基底之間的中途的一個更長的胸廓的黏著器官, 從 Pseudolaguvia inormata 在有一個方面細長的身體 (12.1-13.8% SL vs.13.9-16.1) 與較小的眼 (8.6-11.7% HL vs.12.7-14.9), 從 P. kapuri 有較短的腹鰭 (不 vs. 達到達到第一個臀鰭鰭條的基底; 13.0-14.7% SL vs.15.3-17.9), 而且從 Pseudolaguvia muricata 有比較短的背部與胸棘 (17.3-18.7% SL 和 21.2-26.7 與 20.2-24.3% SL 比較 vs.26.8-35.7 分別地) 與一個較小的眼.(8.6-11.7% HL vs.11.4-15.1) 能從 Pseudolaguvia ribeiroi 被區別進一步有比較不明顯 mesethmoid cornua, 從 Pseudolaguvia shawi 在有一個方面較長的背棘 (17.3-18.7% SL vs.13.4-16.7), 與從 Pseudolaguvia tenebricosa 與 Pseudolaguvia tuberculata 在有一個方面更細長的尾柄 (6.9-7.8% SL vs.7.6-9.0).(參考文獻 58769)
