Holotype male, allotype, 5 males paratypes and 1 female paratype labeled: “ Brasil, SP, São Luiz do Paraitinga (forest), 14.ix.1991, F.A.G. Mello—M.L.F. Camargo, col.”. 3 males paratypes and 3 females paratypes labeled: “ Brasil, SP, S. J. dos Campos, Distr. S. Francisco Xavier, 10–23.i.2008, c.a. 1400 m alt., Fazenda Kolibri, M. P. Bolfarini leg. ” Specimens preserved in ethanol 80%.
Type locality. Brazil, state of São Paulo, municipality of São Luiz do Paraitinga.
Etymology. Named after the Brazilian Orthopterist, Dr. Francisco de Assis Ganeo de Mello.
Diagnosis. This species can be distinguished from other Eidmanacris by the following characters: presence of median crest between lateral projections of metanotal gland, inflated anteriorly with long bristles pointing outwards; posterior apex of ectophallic fold laterally inflated; anterior half of copulatory papilla thicker than posterior in lateral view.
Description. Head. Reddish brown, marbled, dorsum pubescent, with dark spots. Occiput centrally reddish brown, laterally dark brown laterally, with band light brown, thin, going from the occiput to margin of each eye (Fig. 58C); vertex light brown, with anterior maculae dark. Fastigium reddish brown, wider than long, wide as antennal scape; separated from vertex by transverse line vertex forming “v” (Fig. 58C). In frontal view, frons reddish brown, centrally lighter (Fig. 58A). Three ocelli present, well developed, rounded (Figs. 58A, B, C); Maxillary palpi medium brown, elongate, thin, joints 3, 4 and 5 same-sized, apex of joint 5 upcurved, distal half whitish (Fig. 58G). Gena reddish brown, posterior margin lighter in lateral view (Figs. 58A, B). Frontoclypeal suture medium brown, getting darker centrally. Clypeus medium brown; labrum whitish, lower portion yellowish brown. Mandible dark brown, inner margin lighter. Antennal scape light brown, inner surface medium brown (Figs. 58A, B, C); antenomeres medium brown with whitish bands, first band only composed of three antenomeres, posterior bands with five antenomeres.
ThOrax. Pronotum DD reddish brown dark brown, marbled, with dark spots and maculae, posterior margin dark brown; wider than long, inflated, divided by slender, sagittal, line light brown well discernible; DD cephalic margin slightly concave, caudal margin almost straight. (Fig. 58C); ventro-cephalic angle rounded, margin medium to dark brown, ventro-caudal margin dark brown, gradually ascendant (Fig. 58B).
Legs. FI and II yellowish brown, medium to dark brown distally. TI and II yellowish brown, getting darker distally; TI with two same-sized apical spurs, TII with two inner apical spurs, one outer, smaller. FIII light brown, with band of several thin stripes dark brown on outer surface, covered by reddish brown, apical third reddish brown, ventrally yellowish brown (Fig. 58F). TIII medium to yellowish brown; sub-apical spurs 4/4, serrulation above and between them; apical spurs 3/3, more developed on inner surface; inner apical spurs: dorsal one longer (iad), median smaller (iad), ventral smallest (iav) (iad>iam>iav); outer apical spurs: median one longer (oam), dorsal (oad) little longer than ventral (oav) (oam>oad>oav). Basitarsi I, II and III yellowish, pubescent.
AbdOmen. Dark brown, marbled, with dark spots and maculae, sub-cylindrical, divided by thick sagittal band light brown (Fig. 58D).
Male. Medium-sized body, general coloration reddish brown to dark brown, marbled, with dark spots and maculae. FWs medium brown, apex rounded, apparently without veins (Figs. 58B, C); inner margin light brown, inner margins not touching each other, covering metanotal gland area, posterior margin not surpassing metanotum border (Fig. 58C). Metanotal gland present, lateral projections elongate, curved inwards; median crest between lateral projections, anteriorly inflated with long bristles pointing outwards (Figs. 58H, I). Supra-anal plate light brown, laterally darker, anterior margin concave, posterior margin slightly concave; lateral-distal projections medium brown, short, with long setae (Fig. 58J). Subgenital plate light brown, lateral borders darker, longer than wide, anterior third wider, anterior margin sub straight, posterior margin almost straight (Fig. 58K).
Phallic cOmPlex (Figs. 59A–C; 60A–C). Pseudepiphallus: central part of base of pseudepiphallic sclerite narrow; pseudepiphallic arm well sclerotized, upcurved, somewhat slender, apex curved inwards more than 90° angle in dorsal view; apex of pseudepiphallic arm inner margin bifid, forming superior and inferior projections, isosceles triangle-form in lateral view, apparently without bristles on outer surface; anterior projection of pseudepiphallic sclerite elongate, somewhat curved inwards, thin, anteriorly pointed, surpassing median part of pseudepiphallus in lateral view; PsP2 elongate, surpassing posterior extremity of pseudepiphallic arms, straight in dorsal view, down-curved in lateral view, pointed on posterior margin, very sclerotized; PsP1 very sclerotized inwards, short, longer than wide, inner margin concave. Sclerite A external lateral margin rounded in dorsal view. Ectophallic invagination: ectophallic apodeme long, dorso-ventrally flattened in lateral view; ectophallic arc short, located posteriorly to base of pseudepiphallic sclerite in dorsal and ventral views; dorsal projections well sclerotized, short, curved outwards; ventro-posterior projection elongate, sclerotized, curved outwards posteriorly; ectophallic fold membranous, sub apical margins inflated laterally. Endophallus: median-posterior projection of endophallic sclerite elongate, apex reaching PsP2 apex; endophallic apodeme as long as wide, laterally flattened, upcurved in lateral view, limits not reaching ectophallic apodeme anterior margin.
Female. Larger than male, general coloration similar (Fig. 58E). Supra-anal plate light brown, posterior third darker, posterior margin rounded with long bristles (Fig. 58L). Subgenital plate medium brown, lighter band centrally, posterior margin with central concavity rounded (Fig. 58M). Ovipositor apex laterally flattened as in figs. 58N and 58O.
COPulatOry PaPilla (Figs 60D–F). Dorso-ventrally flattened, somewhat longer than wide, anterior half wider than posterior in dorsal and ventral views. In lateral view, anterior half thicker than posterior. Posterior apex unpigmented.
Remarks. The specimens from the District of São Francisco Xavier in the municipality of São José dos Campos, São Paulo, Brazil, are darker than specimens from the municipality of São Luiz do Paraitinga, São Paulo, Brazil. This could be due the different ways these specimens have been preserved.
