( MZUSPAbout MZUSP)GoogleMaps  . Holotype condition: leg III separated from the body, and kept in the same holotype’s vial.

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 View Figure ); pseudepiphallic apex acuminate and curved inward ( Figs 56, 58, 60 View Figure ); pseudepiphallic arms do not converging anteriorly ( Fig 56 View Figure ); legs I, II and III light brown ( Figs 47–52 View Figure ).

Description. Holotype ♂ (01-AMC-PM, Figs 37 View Figure , 39–41, 43–46 View Figure ): similar to A. similis  n. sp. with the following differences: vertex with two lateral spots beside eyes, both projected inward ( Fig. 42 View Figure ); supranal plate posterior margin slightly rounded ( Fig. 45 View Figure ); subgenital plate posterior margin with more pronounced curvature ( Fig. 46 View Figure ); legs light brown ( Figs 37–38 View Figure , 47–52 View Figure ); femur III slightly contrasting the whitish basomedial region with the mediodistal light brown ( Figs 49, 52 View Figure ). 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 View Figure ), while nine females and one male did not present the spots ( Fig. 65 View Figure ); 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 View Figure ).

Phallic sclerites ( Figs 56–60 View Figure ): 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 View Figure ).

Rigth tegmen ( Fig. 61 View Figure , 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.
