DISTRIBUTION. — Carajás National Forest, Pará State.

HABITAT

Ctenorillo ferrarai were originally found in two caves in the Carajás region, located in eastern Pará state, in the Amazon Forest. Unfortunately, data on their habitats were not provided in the original description ( Campos-Filho et al. 2014). Herein we add additional occurrences for this species and some notes on their habitats, along with the first photographs of living specimens ( Fig. 1 ). The Carajás region presents massive iron ore reserves (among other metals) thus being strategically important for the Brazilian economy. However, due to the accelerated growth of iron ore exploitation, the natural landscapes, including both external (forests) and subterranean (caves) components are under unprecedented threat. A considerable part of the iron ore plateaus in the Carajás region is located in the conservation unit of the Carajás National Forest. This National Forest embraces parts of the municipalities of Parauapebas, Canaã dos Carajás, and Água Azul do Norte and is composed by a mosaic of protected areas that adds up to 1.31 million hectares of preserved forests ( Rolim et al. 2006) surrounded by severely impacted areas especially covered by pastures ( Campos & Castilho 2012; Martins et al. 2012). This conservation unit preserves ombrophilous or seasonal forest formations ( Fig. 1A ), with 5% consisting of laterite plateaus, which outcrops on the high areas of the region ( Campos & Castilho 2012). Despite the status of a conservation unit, the Carajás National Forest, is highly altered by mining, farming and illegal deforestation ( Mertens et al. 2002; Souza-Filho et al. 2016; Oliveira et al. 2020; Rizzo et al. 2020). The current climate classification of the region is Aw according to Köppen’s system ( Alvares et al. 2013). It is characterized by a high annual precipitation, which follows a unimodal pattern, with the rainy season peaking between January and March. The region receives an annual total precipitation of approximately 2.033 millimeters, with three-quarters of this occurring during the three wettest months. Monthly average temperatures range from 25.1°C to 26.3°C, with minimums between 15.6°C and 18.3°C (from July to October) and maximums between 34.3°C and 38.1°C, in the remaining months. The region maintains consistently high humidity levels throughout the year, with monthly average relative air humidity varying between 76.8% and 88.5%.

In Serra Norte Mountain Range samples were made in around 900 iron ore caves. Specimens of C. ferrarai ( Fig. 1D ) were found in 114 caves (which corresponds to approximately 12.7% of the caves in the area). Additionally, specimens were also found in 34 caves in the Serra do Tarzan region, in an area close to the Serra Sul complex ( Fig. 1B, C ). Hence, its wide distribution in caves located at different iron ore plateaus indicates that this species certainly occurs outside caves, and is considered a troglophilic species. The caves where the specimens were found are extremely variable in their geological traits, such as the number and size of their entrances, the total length, and the position on the plateaus, among other characteristics, thus indicating that the species seems to be a generalist cave inhabitant, apparently not demanding specific habitat traits. It is important to mention, however, that the quarries expansion in the last years may represent a significant threat, thus monitoring plans should include this species to evaluate any changes in its distributional patterns and population attributes.

REMARKS

Ctenorillo ferrarai was initially documented in two distinct locations of Serra Norte within the Carajás National Forest. Additional surveys conducted in both Serra Norte and Serra do Tarzan provided evidence of similar configurations of dorsal tubercles, which suggests that these specimens are conspecific with the initial discovery. Ctenorillo ferrarai is distinguished by its well-defined tubercles present on both the pereon and pleon segments, as well as a singular rib comprising the first lateral tubercle on epimeron 1 ( Fig. 1 D-G). This trait is of particular interest and will be further examined in other species within this genus.
