|Diagnosis||Diagnosis. A small gecko with up to 47.5 mm SVL; 7–9 supralabials; 14–15 rows of keeled tubercles on dorsum; 20–23 ventral scale rows; 7 or 8 precloacal pores in males; a canthal stripe running from rostrum through the eye and terminating at back of head; lateral second pair of postmentals maximum one quarter the size of first pair; dorsum olive gray with more or less discernible brownish olive blotches.|
Comparisons. Dixonius minhlei sp. nov. differs from all known Dixonius as follows: from D. aaronbaueri by having more ventral scale rows at midbody (20–23 versus 18–19 in D. aaronbaueri); more dorsal tubercle rows (14–15 versus 11 in D. aaronbaueri), more precloacal pores in males (7–8 versus 5 in D. aaronbaueri) and different color pattern (olive gray ground color on dorsum, with more or less discernible brownish olive blotches versus an unpatterned dorsum in D. aaronbaueri); from D. hangseesom by having fewer ventral scale rows at midbody (20–23 vs 22–26 in D. hangseesom); more dorsal tubercle rows (14–15 versus 12–14 in D. hangseesom) and coloration of tail same as the dorsum (versus orange tail in D. hangseesom); from D. melanostictus by having more dorsal tubercle rows (14–15 versus 10–11 in D. melanostictus); fewer precloacal pores (7–8 versus 9 in D. melanostictus), and canthal stripe continues behind orbit to back of head (versus canthal stripe extending along flanks in D. melanostictus); from D. siamensis in smaller size (47.5 mm max. SVL versus 57 mm in D. siamensis), more precloacal pores (7–8 versus 6–7 in D. siamensis) and in having a distinct canthal stripe (versus absence of canthal stripe in D. siamensis); from D. taoi by having more precloacal pores (7–8 versus 5–6 in D. taoi) and different dorsal pattern (dorsum olive gray with more or less discernible round brownish olive blotches versus presence of one or two irregular rows of yellowish marks running from head along flanks in D. taoi); from D. vietnamensis by having more precloacal pores (7–8 versus 5–7 in D. vietnamensis) and in dorsal head and body pattern (blotches on head and dorsum round, more or less discernible vs. dark transversal bands on the occiput and irregular blotches or reticulation on dorsum in D. vietnamensis).
|Comment||Sympatry: Acanthosaura lepidogaster, Calotes emma, and Cyrtodactylus cattienensis.|
Abundance: only known from its original description (Meiri et al. 2017).
|Etymology||The new species is named after our friend and colleague Dr. Minh D. Le from the Faculty of Environmental Sciences, Hanoi University of Science, Vietnam National University, Hanoi, for his continuous and significant contributions towards a better understanding of the diversity and phylogenetic relationships of species from Vietnam and surrounding countries|
