Type material. Male holotype and one male and two female paratypes (deposited in CNAN, temporarily held at UBC-SEM) from Estación de Biología Chamela, Chachalaca trail (19.4966°N, 105.0404°W ‒ 105.0426°W), Jalisco, Mexico, 11.II.2014, W. Maddison & H. Proctor leg.
Etymology. The specific name is a noun in apposition taken from the fictional language Sindarin created by J.R.R. Tolkien. The Sindarin is one of the languages spoken by the Elves. The word “ perian ” is translated as “small” and was used to refer to the Hobbits, the smaller kind of Middle Earth; in reference to its small size, to date the smallest thiodinine ever discovered (see description).
Diagnosis. The males resemble those of Th. nicoleti, Th. minuta comb. nov. and Th. firme sp. nov. by the general appearance of body, but differ in the length of the embolus of the palp, longer in this species ( Fig. 26A View FIGURE 26 ). The females resemble those of Th. minuta comb. nov. by the shape of spermathecae, but differ by the longer ducts ( Fig. 26F View FIGURE 26 ).
Description. Male. Total length: 1.61. Carapace 0.84 long, 0.54 wide, 0.35 high. Ocular quadrangle 0.46 long. Anterior and posterior eye row 0.54 wide. Chelicera paturon with two promarginal teeth, the distal one bicuspid, and one retromarginal bicuspid tooth. Excavation of chelicera absent. Length of femur: I 0.42, II 0.35, III 0.34, IV 0.43; patella + tibia: I 0.53, II 0.41, III 0.38, IV 0.52; metatarsus + tarsus: I 0.43, II 0.37, III 0.40, IV 0.48. Leg formula: 4123. Leg spination: femur I‒III d0-1-1, p0, r0; IV d1-1-1, p0, r0; patella I‒IV 0; tibia I p0, r0, v2 *-0-2a- 1p; II p0, r0, v1 r-0-0; III 0; IV p0, r0, v0; metatarsus I‒II v2-2; III p0, r1di, v0; IV p0, r0 (r1di right), v0. Palp ( Figs 26A‒26D View FIGURE 26 ): tibia wider than long, RTA thin and hook-shaped, RvTA squared ( Figs 26B‒26C View FIGURE 26 ); embolus simple, fixed to the tegulum, arising prolaterally, with a path of 450° (1T+90°) before the distal coil ( Figs 26A‒26B View FIGURE 26 ). Color in alcohol: carapace yellow with black borders, eyes area black, two brown stripes on thoracic region, abdomen dorsally as in genus, ventrally white with dark areas. Femur I yellow, patella I distally dark, tibia and metatarsus I black, tarsus yellow; the rest of the legs as the leg I, but the black areas are light brown ( Figs 25A‒25C View FIGURE 25 ).
Female. Total length: 1.75. Carapace 0.84 long, 0.54 wide, 0.35 high. Ocular quadrangle 0.48 long. Anterior eye row 0.56 wide and posterior 0.58 wide. Chelicera paturon with the same dentition as the male. Length of femur: I 0.38, II 0.32, III 0.32, IV 0.46; patella + tibia: I 0.49, II 0.38, III 0.37, IV 0.54; metatarsus + tarsus: I 0.41, II 0.35, III 0.41, IV 0.49. Leg formula: 4 132. Leg spination: femur I‒III d0-1-1, p0, r0; IV d1-1-1, p0, r0; patella I‒ IV 0; tibia I p0, r0, v2-2 a-2; II p0, r0, v1 r-1r-0; III‒IV 0; metatarsus I‒II v2-2; III‒IV 0. Epigyne ( Figs 26E‒26F View FIGURE 26 ): posterior edge simple, without lobes, copulatory openings posteriorly placed. Color in alcohol: carapace and abdomen as in male. Legs yellow.
