Diplodus holbrooki, Spottail Pinfish [Sparidae]; Holbrookia
, a genus of earless lizards [Phrynosomatidae]).
The keeled earless lizard, Holbrookia
propinqua, is a stenothermal arenophilus lizard restricted to loose sandy soils of southern Texas and northeastern Mexico (Judd, 1973; Axtell, 1998).

Interesting to remark is the finding of these kinds of supraocular scutellation here reported for other genera of such heterogeneous family, like Uma, Uta, Holbrookia
, with analogous geographic distribution.
Atractis penneri is widespread and has been reported in lizards of the genera Callisaurus, Crotaphytus, Gambelia, Holbrookia
, Phrynosoma, Sceloporus, Uma and Uta occurring from the western United States, northern Mexico and Baja California (Baker 1987).
We have documented the decline of two wide-ranging lizard species (Sceloporus undulatus and Holbrookia
maculata) in the Sandhills region of Nebraska.
Within Phrynosomatinae are the genera Callisaurus, Cophosaurus, Holbrookia
, Phrynosoma, and Uma, and within Sceloporinae are Petrosaurus, Sceloporus, Urosaurus, and Uta.
elegans ranges from coastal southern Sinaloa, Mexico, north through central and eastern Sonora, to south central Arizona, and to extreme southwestern New Mexico where it inhabits mesquite grasslands and grassy oak and juniper woodlands (Axtell 2009).
Oviductal morphology and sperm storage in the keelep earless lizard, Holbrookia
We compared the specimens with modem skeletal material of Callisaurus, Cophosaurus, Holbrookia
, Petrosaurus, Phrynosoma, Sceloporus, Uma, Urosaurus, and Uta.
Finally, areas on the Engineering Initiative Group-Leased Training Area may have been suitable for the lesser earless lizard Holbrookia
maculata; however, this species is common on sandy or gravelly soils (Conant and Collins, 1998).
sexlineatus are sand-loving species, the former is mostly limited to alluvial deposits (Walker 1987a) whereas the latter is mostly limited to broadly distributed eolian deposits where species of the lizard genus Holbrookia
and the sandbur genus Cenchrus are ecological indicators (Paulissen et al.
