背的软条 (总数) : 12 - 14; 臀鳍软条: 13 - 15. Xenotoca doadrioi differs from other congeners of the Xenotoca eiseni group and other Xenotoca species occurring in the Pacific Coast drainages by the combination of the following characters (none unique to the species): females with 14 dorsal rays (vs. 15 or 16 in X. melanosoma and 13 in X. lyonsi), 14 anal fin rays (vs. 5 or 16 in X. melanosoma), 12 pectoral fin rays (vs. 13 in Xenotoca eiseni), 8 caudal peduncle scales (vs. 9 in Xenotoca eiseni and X. melanosoma), 32 scales in a lateral series (vs. 31 in Xenotoca lyonsi), and 10 suparorbital pores (vs. 9 in Xenotoca eiseni and X. lyonsi). Females of X. doadrioi have large caudal peduncle (standard length/end of the anal fin-hypural plate distance = 3.8, vs. 4.1-4.2 in X. eiseni and X. lyonsi) and SL/end of dorsal fin-hypural plate distance = 3.6 (vs. 3.9-4.2 in X. eiseni and X. lyonsi), large eye (Head length/Eye Diameter = 3, vs. 3.5-3.7 in X. eiseni and X. lyonsi). Males possess 14 dorsal rays (vs. 15 or 16 in X. melanosoma and 13 in X. lyonsi), 14 anal fin rays (vs. 15 or 16 in X. melanosoma), 12 pectoral rays (vs. 13 in Xenotoca eiseni), 8 caudal peduncle scales (vs. 9 in Xenotoca eiseni and X. melanosoma), 11 transversal scales (vs. 9 in X. lyonsi), 32 scales in a lateral series (vs. 31 in Xenotoca lyonsi) and 10 suprorbital pores (vs. 9 in Xenotoca eiseni and X. lyonsi). It has a smaller head (Head Length/Head High = 1.4, vs. 1.1-1.2 in Xenotoca eiseni and X. lyonsi), the body is less high (Standard Length/pelvic-pectoral fin distance = 4.7 vs. 4-4.4 in Xenotoca eiseni and X. lyonsi) and large caudal peduncle (Standard length/ end of the anal fin-hypural plate distance = 3.8 vs. 4-4.2 in Xenotoca eiseni and X. lyonsi), and standard length /end of dorsal fin-hypural plate distance 3.8 (vs. 4.1-4.3 in Xenotoca eiseni and X. lyonsi) (Ref. 117630).

This species occurs in permanent pond, spring, reservoir, and seasonally affected streams. The type locality is a permanent pond where this species inhabits an area with turbid and shallow water of no more than 1.5 m deep and with bottom comprising of mud and gravel and no water plants present. Other fishes collected in the area are the following: Xenotoca melanosoma, Goodea atripinnis, Poeciliopsis infans, and the introduced Xiphophorus variatus and Oreochromis sp.. In the El Moloya Spring, this species inhabits clear water with gravel to muddy bottom and water plants. The following species are found in this pond: X. melanosoma, Zoogoneticus purepechus, Ameca splendens, G. atripinnis, P. infans, and the introduced Oreochromis sp. In Oconahua Dam, this species live in turbid water with a muddy bottom and with few water plants. Other species occurring in this dam include the following: X. melanosoma, G. atripinnis, P. infans, as well as the introduced Lepomis macrochirus, and Cyprinus carpio. This species is also collected in a seasonally fluctuating stream (San Marcos stream) that is dry for most of the year, but when water is present the surface of the stream is totally cover with Eichhornia crassipes Martius, Thypa sp., and Cyperus sp. and the water at this site is highly polluted by organic matter and is turbid. This species is also found in Sahuaripa stream, an irrigation channel totally modified and fed by a water pump. Other species collected in San Marcos and Sahuaripa streams are X. melanosoma, Allotoca sp., G. atripinnis, P. infans, and Oreochromis sp. (Ref. 117630).
