Distribution	Mexico (Isla Santa Catalina) Type locality: Isla Santa Catalina, Gulf of California.
Reproduction	oviparous (not imputed, fide Zimin et al. 2022)
Types	Holotype: USNM 64263 (Formerly AMNH 5478)
Diagnosis	Diagnosis: A robust species of medium size (length of head and body of adult male, 85 mm.), especially bristling with large, long-pointed but not spinous scales; 4-6 preauriculars in oblique row, relatively long and pointed, overlapping at bases; dorsal scales (7 straight longitudinal rows) much larger than ventrals; laterals crowded in oblique rows, graduated in size to meet ventrals, the shape changing through in.tennediate stages from angular, long-pointed, weakly denticulate scales to the rounded ventrals with their 2-4 equal points or scallops; rump and proximal caudals equal to dorsals; dorsals about 28 from interparietal to base of tail, 5 in head length (muzzle to interparietal); distance from base of 5th toe to end of 4th equal to length from tip of muzzle to anterior border of ear; femoral pores, 20. Coloration of adult male rufous dorsally, blue lateroventrally verging into green above, blue on chest between arms, and on chin; sides prominently marked from above arm to groin with about 11 longitudinal parallel brown lines following the direction of the scales; posterior gular region black, also black more or less as follows: on ventral arm, breast, median abdominal area, groin, ventral femur (Dickerson 1919: 467).
Comment	Abundance: only known from the type locality (Meiri et al. 2017).
Etymology	The Latin lineatus, "linear," and the diminutive -ulus refer to the finely striped dorsal pattern.
