Synonym	Trimorphodon paucimaculatus TAYLOR 1938: 527 Trimorphodon lambda paucimaculata — FUGLER & DIXON 1961: 17 Trimorphodon lambda paucimaculata — HARDY 1969: 206 Trimorphodon paucimaculatus — DEVITT et al. 2008 Trimorphodon paucimaculatus — WALLACH et al. 2014: 744
Distribution	Mexico (Sinaloa, Zacatecas, Jalisco, Nayarit) Type locality: Mazatlan, Sin., Mexico.
Reproduction	oviparous
Types	Holotype: INHS (= UIMNH) 25072 (was EHT. No. 709, collected July 24, 1934; E. H. Taylor, collector)
Diagnosis	Diagnosis: A species related to T. bi-sciitatus Dumeril and Bibron, but not having the preoculars touching frontal, and with the dorsal spots greatly elongated and fewer in number. Frontal as long as parietal; prefrontals as wide as long. Ventrals, 253; anal divided; subcaudals, 76 (from TAYLOR 1936). Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers. These details, e.g. detailed descriptions or comparisons (about 51 characters) are available for collaborators and contributors. Please contact us for details.
Comment	Synonymy: Has been considered as a synonym of T. biscutatus biscutatus, e.g. by Scott 1984. Habitat: partly arboreal (Harrington et al. 2018).
Etymology	Not given by Taylor but apparently named after the smaller number of dorsal spots, from Latin “pauci” = few, and macula = spot.
