Etymology. Named after Dr. Carmem Silvia Fontanetti, for her contributions on the morphology and cytogenetics of crickets. This species was formerly described by Dr. Silvio Shigueo Nihei in his undergraduate studies, but was not published ( Nihei, 1997).

Diagnosis. This species can be distinguished from other Eidmanacris by the following characters: small body in relation to other species; antennae dark brow with bands composed of whitish antenomeres, c.a. 18–20; inner margin of male FWs light brown; pseudepiphallic arms slightly sinuous in dorsal view; PsP2 apex pointed in lateral view, curved inwards in dorsal view, apparently without membranous sphere; endophallic apodeme short; copulatory papilla little longer than wide, dorso-ventrally flattened in lateral view, posterior margin slightly concave, unpigmented in dorsal view.

Description. Head. Pale yellow to light brown. Occiput medium brown with maculae light brown, band light brown going from occiput to margin of each eye; vertex light to medium brown with three vertical lines, lateral little conspicuous in dorsal view ( Fig. 55C ). Fastigium medium to dark brown, with two rows of bristles, slightly longer than wide, slightly narrowed toward the apex, separated from vertex by straight line forming “v” ( Fig. 55C ). Frons medium brown, with three bands dark brown, vertical, two below eye and antennal scape, one above clypeus ( Figs. 55A, B ). Three ocelli present, well developed, forming isosceles triangle, central flattened at bottom, lateral elliptical ( Figs. 55A, B, C ). Eyes with unpigmented small area on supero-internal angle ( Fig. 55C ). Maxillary palpi, long, thin, pilose, medium brown, distal portion of joints whitish; joints 3 and 4 almost same-sized ( Fig. 55G ); apex of joint 5 upcurved. Gena light brown, posterior medium brown stripe from occiput to mandible in lateral view ( Fig. 55B ). Frontoclypeal suture yellowish, clypeus light brown, lateral dark; labrum whitish, lower portion pale yellow. Mandible light brown, inner margin dark brown. Antennal scape light brown, dark brown on inner surface ( Fig. 55A ); antennae dark brow with bands composed of whitish antenomeres, c.a. 18–20.

ThOrax. Pronotum DD wider than long, medium to dark brown, with sparse dark spots and maculae, slightly pubescent, inflated, divided by light brown to pale yellow sagittal line ( Fig. 55C ); DD cephalic margin slightly concave, caudal margin sub-straight ( Fig. 55C ); ventro-cephalic angle rounded, ventro-caudal margin gradually ascendant ( Fig. 55B ).

Legs. FI and II dark yellow, annulated with dark brown. TI and II dark yellow, annulated with medium brown; TI with two same-sized apical spurs; TII with two inner apical spurs, one outer, smaller. FIII pale yellow, with thin stripes medium brown on outer surface, dorsal surface and apical third medium brown ( Fig. 55F ). TIII medium brown, apical third pale yellow; subapical spurs 4/4, with serrulation above and between subapical spurs, except between two distal ones; apical spurs 3/3, more developed on inner surface: dorsal (iad) and median one(iam) subequals, ventral smallest (iav) (iam>iad>iav); outer apical spurs: median one longer (oam), dorsal sub-equal in length (oad), ventral smaller (oav) (oam>oad>oav). Basitarsi I, II and III yellowish.

AbdOmen. Sub-cylindrical, medium to dark brown, marbled, pubescent, divided by thin pale yellow sagittal line.

Male. Small-sized body in relation other species of genus, general coloration medium brow, marbled. FWs dark brown, short, sub-triangular; posterior part of inner margin and apex whitish connected to single vein that divides outer part of FW as lateral field, glandular thickening present distally, but reduced ( Fig. 55C ); inner margin light brown, inner margins not touching each other; not covering metanotal gland centrally and not surpassing metanotum posterior border ( Fig. 55B, C ). Metanotal gland present, anteromedian crest forming an inverted triangle with cluster of bristles; lateral projections short and cylindrical, parallel ( Figs. 55H, I ). Supra-anal plate dark brown, pubescent; anterior margin slightly concave, lateral margins curved inwards, lateral-posterior projections very short, medium brown; posterior margin sub-straight ( Fig. 55J ). Subgenital plate longer than wide, with lateral pubescence, laterally dark brown, centrally medium to light brown; anterior margin almost straight, posterior margin rounded with small invagination centrally ( Fig. 55K ).

Phallic cOmPlex ( Figs. 56A–C ; 57A–C). Pseudepiphallus: central portion of base of pseudepiphallic sclerite narrow in dorsal view; pseudepiphallic arms sclerotized, hard, slightly sinuous in dorsal view, upcurved in lateral view; apex of pseudepiphallic arm with bristles, folding itself to dorsal and forming superior projection; internal projection present, apex rounded; PsP2 hardly sclerotized, surpassing posterior extremity of pseudepiphallic arms, apex pointed in lateral view, curved inwards in dorsal view, membranous sphere apparently absent; sclerite A sinuous, very thin, articulated with PsP2; PsP1 elongate, well sclerotized, rounded at apex, curved inwards. Ectophallic invagination: ectophallic apodeme short, relatively enlarged at anterior third in dorsal view; ectophallic arc located posteriorly to base of pseudepiphallic sclerite in dorsal view; ventro-posterior projection elongate; dorsal projection sclerotized, apex pointed. Endophallus: median-posterior projection of pseudepiphallic sclerite elongate, not surpassing PsP2 apex; lateral-posterior lobes of endophallic sclerite elongate; endophallic apodeme not so elongate, not reaching the middle part of pseudepiphallus.

Female. Larger than male, general coloration similar ( Fig. 55E ). Supra-anal plate anteriorly medium brown, posteriorly dark brown, anterior margin slightly concave, posterior margin rounded with relatively long bristles ( Fig. 55L ). Subgenital plate medium brown, marbled, wider than long, anterior margin slightly concave, posterior margin with central concavity ( Fig. 55M ). Ovipositor as in figs. 55N, O.

COPulatOry PaPilla ( Figs. 57D–F ). Little longer than wide, dorso-ventrally flattened in lateral view, anterior margin membranous, posterior margin slightly concave in dorsal view, unpigmented.
