Type material: Holotype ♂, code (01-AMC-PM): Brazil, State of Ceará, municipality of Crato, Araripe-Apodi National Forest (Flona do Araripe-Apodi), 7°14'44.42"S, 39°29'47.64"W, 15.i.2013, Pereira, M.R & Zefa, E. leg. (MZUSP). Holotype condition: leg III separated from the body, and kept in the same holotype’s vial. Paratypes: same data of holotype (3♂ e 11♀), codes: ♂ 7NE53-GRYLLO/ARA/ZEFA, ♂ 02-AMC-PM, ♂ 616C6-GRYLLO/ ARA/ZEFA; ♀ 3TS98-GRYLLO/ARA/ZEFA, ♀ 9BE33-GRYLLO/ARA/ZEFA, ♀ 3V15 M-GRYLLO/ARA/ ZEFA, ♀ 361YQ-GRYLLO/ARA/ZEFA, ♀ 05-AFC-PM, ♀ 03-AFC-PM, ♀ 02-AFC-PM, ♀ 01-AFC-PM, ♀ 04- AFC-PM, ♀ 06-AFC-PM, ♀ 07-AFC-PM), (MZUSP).
Etymology: the specific name cruscastaneus is derived from the Latin crus =leg and castaneus =brown, and refers to the light brown color of these cricket’s legs.
Diagnosis: combination of the following characteristics: general morphology of the pseudepiphallic paramere 1 (Figs 56–60); pseudepiphallic apex acuminate and curved inward (Figs 56, 58, 60); pseudepiphallic arms do not converging anteriorly (Fig 56); legs I, II and III light brown (Figs 47–52).
Description. Holotype ♂ (01-AMC-PM, Figs 37, 39–41, 43–46): similar to A. similis n. sp. with the following differences: vertex with two lateral spots beside eyes, both projected inward (Fig. 42); supranal plate posterior margin slightly rounded (Fig. 45); subgenital plate posterior margin with more pronounced curvature (Fig. 46); legs light brown (Figs 37–38, 47–52); femur III slightly contrasting the whitish basomedial region with the mediodistal light brown (Figs 49, 52). Measurements (mm/mm2): body length, 7.7; pronotum length, 1.19; pronotum width, 1.58; head width, 1.46; interocular distance, 0.82; femur III length, 4.25; tibia III length, 3.8; auditory tympanum area, 0.02; supranal plate length, 0.5; supranal plate width, 1.15; subgenital plate length, 0.99; subgenital plate width, 1.11.
Remarks on paratypes. Head spots: paratypes ♀ 02-AFC-PM, ♀ 3TS98-GRYLLO/ARA/ZEFA; ♂ 02-AMC- PM, ♂ 7NE53-GRYLLO/ARA/ZEFA showed a pronounced dark spots at the vertex, similar to the holotype (Fig. 43), while nine females and one male did not present the spots (Fig. 65); auditory tympanum morphology and the arrangement of the subapical and apical spurs of the tibia III are similar to A. similis n. sp. (Figs 53–55).
Phallic sclerites (Figs 56–60): paratypes 7NE53-GRYLLO/ARA/ZEFA and 616C6-GRYLLO/ARA/ZEFA) similar to A. similis n. sp. with the following differences: morphology of the PsP1 according to figures 58–60; pseudepiphallus apex acuminate and curved inward; pseudepiphallic arms do not converge anteriorly (Fig. 56).
Rigth tegmen (Fig. 61, paratype 7NE53-GRYLLO/ARA/ZEFA): the areas of the dorsal and lateral field, as well as their veins, are similar to A. similis n. sp., with the following differences: Harp with three veins; mirror with two cross veins; lateral field with pour marked accessory veins; veins 1A and Cu2 almost touching next to the connection of Cu2 with Hcv; stridulatory file with 103 teeth. Measurements (mm/mm2): dorsal field length, 3.66; dorsal field width, 2.17; harp area, 2,11; mirror area, 1.11; lateral field with four pour marked accessory veins, length, 3.30; lateral field width, 0.76; stridulatory file length, 1.33.
Female (Figs 62–75): body shape and color pattern similar to holotype, with the following differences: subgenital plate wider than long and with an U-shaped notch in the apex (Fig. 69); supranal plate triangular with apex rounded (Fig. 68); ovipositor apex acuminate (Figs 70, 71). Copulatory papilla (n = 3): idem to A. similis n. sp. (Figs 72–75).
