Figure 43. A in High and dry: integrative taxonomy of the Andean spider genus Nerudia (Araneae: Pholcidae)

Figure 43. A, density of records of arachnids surrounding the geographic distribution of Nerudia representatives, with numbered high density regions (reddish areas: 1. Santiago; 2. Córdoba; 3. Cafayate; 4. Tilcara). Dotted line represents 500 km buffer around Nerudia records (black dots). Note that Nerudia records are concentrated in poorly sampled regions (bluish areas). B, relative occurrence rate (ROR) of Nerudia species, with numbered biogeographic regions. Polygons represent the biogeographical regionalisation (sensu Morrone, 2017) in the Andean (5) and Neotropical (6–12) regions. Neotropical provinces: (6) Prepuna; (7) Monte; (8) Pampean; (9) Chaco; (10) Yungas; (11) Puna; and (12) Atacama. The reddish areas denote regions where Nerudia is expected to occur; in some of these, no Ninetinae have ever been recorded: the Atacama province in Chile and the Puna province in Bolivia.
