AE4287B1FF9DFFE9D090CEAE7E35A802.taxon	diagnosis	Diagnosis. Females of C. santanensis have the typical sucker-like female gonopods of the eastern South America Charinus (e. g., de Miranda et al., 2021, figs 6 and 7 a – b, e – f); it is distinguishable from other species by the following combination of characters: leg I with 23 articles on tibia and 41 on tarsus; median (Fig. 7 C) and lateral eyes (Fig. 7 B) present and well developed; eight cheliceral teeth (Fig. 3 A); pedipalp femur with 4 – 5 dorsal and 4 – 5 ventral spines; pedipalp patella with 5 dorsal and 4 ventral spines (Fig. 2 A, B); pedipalp tarsus with two dorsal spines; cleaning organ with 27 superior row of ventral setae (spr Fig. 8 C); frontal and caudal series of trichobothria on leg IV distitibia with six setae.

AE4287B1FF9DFFE9D090CEAE7E35A802.taxon	description	Description. Male described by (Vasconcelos & Ferreira, 2017). Female. Carapace (Fig. 1 A): flattened, wider than longer. Prominent lateral and median eyes (Fig. 1 A, C; 4 B; 6; 7 A, B, C); from the median eyes starts a thin median furrow that reaches around the median area of the lateral hump pair, behind the lateral eye spots. Median eyes developed within a tubercle, situated in a small depression. Curved carina present ventral to lateral eyes (Fig. 1 C). Anterior margin with 6 strong setae oriented upwards (Fig. 7 A). Many tiny punctuations, more abundant in the frontal area (Figs 1 C, 4 B). Different from male, carapace distal portion above the coxa of legs I is slightly curved upwards and serrated. Carina begins at the corners of the anterior margin extending from the coxa of legs II to the corners of the posterior margin, fovea deep and oval located posterior to the center. Surface covered with hydrophobic crystals secreted from major glands distributed across the tegument (Fig. 6). Sternum (Fig. 1 E). Trisegmented, the two posterior segments less sclerotized than the anterior. Pentasternum rounded and convex, smaller than the other segments, with two apical setae. Tritosternum as in male with similar setae pattern but with a wider round basis and projected anteriorly reaching the base of the chelicerae. Distance between segments as in male. Abdomen (Figs 1 A – B, 8 A) oblong, with visible punctuations, thicker than on the carapace. Anal tubercle ovoid with two setae located at the median field and two pairs laterally. Chelicerae (Fig. 2 C – D; 4 A, C, F). Cheliceral furrow with 4 internal teeth (Fig. 3 A; 4 A); distal tooth bifid (1 a – 1 b), distal cusp bigger than the proximal (Fig. 3 A – 1 a> 1 b; Fig. 4 A, C). Teeth length: IV> Ia> Ib = II> III. Claw with 8 denticles, the basal larger (Fig. 3 A, Fig. 4 C). Basal segment of chelicera with seven lined up setae close to base of article. Pedipalp. Trochanter (Fig. 2 A, B): ventral spiniform apophysis, sizes and spinulation patterns as in males, dorsal series of strong setae as in males. Femur: strong dispersed dorsal setae and two setiferous tubercles on the basal portion. Four dorsal spines (five in male holotype, four in the male paratype) of sizes FI> FII> FIII> FIV. Four ventral spines with one spine proximally, between spine I and border of palp. Patella: five dorsal spines I> II> III> IV> V. Four strong ventral spines of sizes I> II> III> IV. Tibia (Fig. 2 A, B): densely setose; two dorsal spines; distal spine twice larger than the basal. Ventral spine same size of dorsal basal, located at the distal half. Tarsus: two spines as in males opposite to cleaning organ (Fig. 2 B). Distal spine twice as large as the basal spine. Cleaning organ occupying half the length of the article (Fig. 2 A); ventral row with 24 – 27 setae. Claw: long with curved sharp tip, pilosity absent (Fig. 1 D). Legs (Fig. 3 B, 4 D, G, H). All segments setose. Ventral corner of the prolateral face of femora II – IV projecting in a distinct spiniform process. Femur length I> III> II> IV. Tibia I with 23 articles. Tarsus (basitarsus + tarsus) I with 41 articles. Leg IV: Basitibia: divided into 4 pseudo-articles, with one trichobothrium located proximally on the BT 4. Distitibia (Fig. 3 B): 3 basal and 15 distal trichobothria (total of 18); trichobothrium patterns as described for male (Vasconcelos & Ferreira, 2016: fig. 23: 285). Tarsus composed of 4 segments. Basitibia-distitibia length DT = BT 1> BT 4> BT 3> BT 2. Measurements (Table 1) Female: Cephalothorax length 3.75, width 4.83. Abdomen length 6.67.

Color pattern (in alcohol). Chelicerae, pedipalps and carapace yellowish-brown as in males. No significant difference among both sexes. Legs uniformly light yellowish-brown. Abdomen pale yellow. Color of live animals is cool earthy gray (Fig. 9). Genitalia. Female. (Fig. 5) Rounded genital operculum with strong setae on the border; gonopods sucker like, cylindrical shape, longer than wide (Fig. 5 A, C). Opening protruded, distal portion radially expanded (Fig. 5 D). Both gonopods separated by half the width of its bases. The general pattern of gonopods is similar to that of other eastern South America species of Charinus.	en	Paredes-Munguia, Williams, Teixeira, Renato Augusto, Soares-Costa, Rafael, Ferreira, Rodrigo Lopes, Miranda, Gustavo Silva De (2025): Conservation, systematics and ultrastructure of the poorly known amblypygid species Charinus santanensis (Charontidae, Amblypygi) from Caatinga caves in Brazil.
