While working on a revision of Triorophus LeConte, 1851 we examined type material for the genus. One species, Triorophus punctatus LeConte, 1851 (Figs. 1a–1e), was described from a dead, partial specimen (Type 4475, Museum of Comparative Zoology, Harvard University) collected at “Vallecitas,” California in October or November of 1850 (LeConte, 1851). The locality likely refers to Vallecito, a contemporary United States Army depot and stage station (Roberts, 1988) located on the western edge of the Colorado Desert in eastern San Diego County (32.9755°, -116.35°).
The purpose of this study was to better understand the relationships between diurnal variations of air temperature measured hourly at the soil surface, compared with the thermal infra-red (TIR) emission properties of soil surfaces located in the Lower Colorado Desert of California, eastern Riverside County. Fifty air temperature loggers were deployed in January of 2017 on wooden stakes that were driven into the sandy or rocky desert soils at both Ford Dry Lake and the southern McCoy Mountains wash. The land surface temperature (LST) derived from Landsat satellite images was compared to measured air temperatures at 1 m and at the soil surface on 14 separate dates, until mid-September, 2017. Results showed that it is feasible to derive estimated temperatures at the soil surface from hourly air temperatures, recorded at 1 m above the surface (ambient). The study further correlated Landsat LST closely with site measurements of air and surface temperatures in these solar energy development zones of southern California, allowing inter-conversion with ground-based measurements for use in ecosystem change and animal population biology studies.
