FIGURE 3. Sampling site, A, (grey point) of Canthidium quercetorum new species in Oaxaca (grey area), Mexico (white area). Satellite images of Canthidium quercetorum sampling sites in a deciduous oak forest B, at the dry season (left) and C, at the end of the rainy season (right) (March 2017, November 2014). Bright colours on the left image indicate a forest with trees that have lost their leaves; whereas green vegetation on the same image shows pine-oak forest at higher altitudes, where Canthidium quercetorum has not been collected. On the right image, oak forest appears with nearly maximum leaf density at the end of the rainy season. Distribution of D, dry oak forest (dark brown area), situated between approximately 1800 and 2400 m. Sampling site of Canthidium quercetorum is represented by the white rectangle. On the left lower side of the image the urban area of the Oaxaca Metropolitan Region can be seen. The dark green area on the right upper side of the image represents pine-oak and pine forest (highest elevation is around 3100 m). Satellite image was provided by GoogleEarth, and oak forest distribution by the Instituto Nacional de Estadística, Geografía e Informática.
