Etymology: Diplectrum: Greek, di = two + Greek, plektron = sting, spur (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 15 - 150 m (Ref. 9342), usually 60 - 90 m (Ref. 9342). Tropical; 32°N -
Eastern Pacific: Gulf of California to Peru; including the Galapagos Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 9342); common length : 15.0 cm TL male/unsexed; (Ref. 55763)
Body elongate, not very deep, and little compressed, its depth contained 3.2 to 3.8 times in standard length; caudal peduncle very thick; preopercular angle with a broad "spur" consisting of 6 to 12 large spines; first gill arch with 21 to 27 gill rakers; anal rays 8; body grayish brown; flanks with indistinct dark, double, vertical bars; snout and cheeks with yellow stripes; soft dorsal fin with a dark band along its base (Ref. 55763).
Inhabits sand or muddy-sand bottoms. Probably too small in size to be of commercial importance.
