Arthrosolaenomeris Schubart, 1943 View in CoL

Arthrosolaenomeris Schubart, 1943: 143 View in CoL .

Type species: A. chapadensis Schubart, 1943 View in CoL , by original designation; Schubart, 1958: 205; Schubart, 1960: 453; Jeekel, 1971: 249; Hoffman, 1976: 177; Hoffman, 1980: 151.

Diagnosis. Males of Arthrosolaenomeris differ from those of other Arthrosolaenomeridini genera by the combination of the following characters: rectangular ventral projections in the post-gonopodal sternites ( Fig. 30E View FIGURE 30 ) (acuminated in A. curupira n. sp. and A. caipora n. sp.); posterior edge of the gonopod aperture with a small dentiform process; presence of a secondary process in medial portion in the prefemoral process of the gonopod ( Fig. 4D–F View FIGURE 4 ) (absent in A. iara n. sp.); presence of a rounded extension of the gonocoxae, in oral view ( Fig. 32D View FIGURE 32 ); and apex of the solenomere abruptly descending ( Fig. 4D View FIGURE 4 ).

Description. General characters: Body length between 47.78 mm ( A. caipora n. sp.) and 69.42 mm ( A. iara n. sp.). Coloration (specimens long preserved in 70% ethanol) variable between species, ranging from ocher to reddish brown, paranota tip and posterior border of the metaterga slightly whitish (some specimens of A. pantanalensis show a purple coloration for the whole body). Gnathochilarium: lingual plate covered by several setae; mentum centrally covered by setae, with smooth edges and stipes covered by thick setae (sparsely covered in A. curupira n. sp. and A. caipora n. sp.). Body rings: cuticle slightly rough; alignment of paranota in posterior view curved ventrally (straight in A. caipora n. sp.). Sternite of the fourth segment with a pair of projections, sternite of the fifth segment with two pairs of projections covered with setae. Sternite of sixth body ring with two pairs of ventral projections; seventh body ring with a pair of ventral projections (absent in A. chapadensis ) and post-gonopodal sternites with two pairs of rectangular ventral projections (acuminate in A. curupira n. sp. and A. caipora n. sp.). Paranota form: round to slightly rectangular ( Figs 4B View FIGURE 4 , 8B View FIGURE 8 ). Legs: podomeres with several thick ventral setae ( Fig. 31A View FIGURE 31 ) and granules in the tibia and tarsus ( Fig. 31F View FIGURE 31 ) (except in A. curupira n. sp. and A. caipora n. sp.), dorsal lobe of prefemur conspicuous of the anterior legs ( Fig. 31A View FIGURE 31 ) and a ventroapical projection in the prefemur of the post-gonopod legs ( Fig. 31E View FIGURE 31 ).

Male characters: Leg pair of the third body ring with the coxae presenting the rectangular genital papilla. Gonopod aperture on seventh body ring with the posterior margin excavated and with a small process. Gonopods: gonocoxae equivalent to about half the length of the telopodite, cylindrical, without a spiniform process. Prefemoral process ( Figs 4D–F View FIGURE 4 ): elongate with a dorso-basal process and a secondary process in its medial portion (long in A. chapadensis , A. pantanalensis , A. saci n. sp., A. iara n. sp. and short in A. curupira n. sp., A. caipora n. sp.). Cingulum in an apical position ( Fig. 4F View FIGURE 4 ) (middle position in A. caipora n. sp.). Solenomere long and thin with its apex abruptly descending ( Fig. 4D–F View FIGURE 4 ).

Female characters: Vulvae: oval-shaped, having equal proportions in lateral view, with an operculum advanced ( Figs 10A–B View FIGURE 10 ).

Distribution. States of Mato Grosso, Mato Grosso do Sul and São Paulo ( Fig. 11 View FIGURE 11 ).

Composition. Arthrosolaenomeris chapadensis Schubart, 1943 ; A. pantanalensis Schubart, 1943 ; A. saci n. sp.; A. curupira n. sp.; A. caipora n. sp.; A. iara n. sp.
