A species of Trimma with a partly scaled predorsal region, midline naked or partly naked, cycloid scales at the sides of the nape reaching to above a point between posterior margin of the operculum and the eyes; cheek and operculum naked; pectoral-fin base usually fully scaled with posterodorsal 2 scales slightly enlarged; prepelvic region covered with small cycloid scales in 5–6 rows; interorbital narrow, with a moderate groove; no or very shallow groove behind this; a distinct low ridge at the posterior end of the interorbital; a low crest on the nape from the first dorsal origin to above the posterior opercular margin, extending anteriorly into a shallow median groove, groove extending to just behind eyes; second dorsal rays usually I 9 ; anal rays usually I 8 ; pectoral rays unbranched or with 1–5 rays branched at the extreme tips; fifth pelvic ray unbranched and about one-fourth to onehalf the length of the fourth ray, other rays with 2 terminal tips, pelvic fins largely separate, connected only at base, fins widely separate, the distance between the two fins being greater than the width of the base of a single fin; posteriormost prepelvic scale covering the basal membrane; a dark brown spot or bar extending posteroventrally from the eye; and the body with irregular brown interconnecting bars, forming a zigzag pattern ( Fig. 26 ).
