وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
الأشواك الظهرية (المجموع) : 4 - 7; الأشعة الظهرية الناعمة (المجموع) : 8 - 12; شوكة شرجية: 1; أشعه شرجية لينه: 18 - 26. This species is distinguished and differs from L. sicculus by the following characters: Labidesthes vanhyningi have the anterolateral processes of the posttemporals
shorter than width of the base (vs. L. sicculus having the processes longer than width of base); with a midlateral stripe that does not taper, usually expanding, to insertion of pectoral fin in advance of the first dorsal-fin (vs. tapering to insertion of pectoral fin in advance of first dorsal fin); a ratio of thoracic length to abdominal length less than 2 (vs. greater than 2) (Ref. 104856).
