Lasiodora camurujipe n. sp.

( Figs 10 View FIGURES 8–15 , 16 View FIGURE 16 ─18, 203─224)

Diagnosis. Lasiodora camurujipe n. sp. males and females resemble those of L. subcanens , L. sertaneja n. sp. (part) and L. klugi (part) by having spiniform setae not limited to the upper area of retrolateral maxilla ( Figs 209 View FIGURES 209 ─210). They can be distinguished from those of L. klugi (part) and L. sertaneja n. sp. (part) by having the distal maxilla covered with several spiniform setae on most of its upper, median and lower areas, whereas in these two species normally, there are only a few spiniform setae on the median and lower areas. From L. subcanens , they differ by the retrolateral distal maxilla covered with several well developed spiniform setae ( Figs 209 View FIGURES 209 ─210) and by lacking the abundant whitish setae covering most of the carapace, dorsal chelicerae and legs that L. subcanens have ( Figs 219 View FIGURES 219 -222).

Etymology. The specific epithet refers to the type locality, the Camurujipe farm, a RPPN (Private Natural Heritage Reserve), in the Municipality of Mata de São João, State of Bahia, Brazil, where the types were collected.

Distribution. Brazil, state of Bahia, endemic to the region from Salvador to Mata de São João municipalities ( Figs 223 View FIGURES 223 ─224).

Natural history. The types and additional specimens were collected in the RPPN Camurujipe at night. The area is covered with Brazilian Atlantic Forest. All them were inside the spaces between Ficus tree roots. None were found under fallen logs or rocks, as well as inside burrows on ravines. As with L. klugi (see above), Ficus trees seem to be an important element for the spiders of this species, providing retreats.

The area of distribution of. L. camurujipe n. sp. is roughly the same as those of other theraphosid species, such as Typhochlaena seladonia C. L. Koch, 1841 , Iridopelma zorodes (Mello-Leitão, 1926) , Pachistopelma bromelicola Bertani, 2012 (Bertani, 2012) and Vitalius sapiranga Bertani, 2023 . It is concerning that this area of endemism is suffering an accelerated process of anthropization. Conservation areas on this biodiversity rich region should be created to protect this fauna (pers. obs.).
