( Figs. 14 A – D, 15, 19A, 24)

Phoremia sp. B in Sperber (1999)

Etymology. The specific epithet refers to Dr. Edison Zefa, professor of Universidade Federal de Pelotas (UFPel) and Brazilian Orthopterologist.

Type. Holotype, male, Brasil, MG, Viçosa, Mata da Biologia, 30.x.2002 (Mendes, M. H leg.).

Diagnosis. This species may be distinguished from the other species of Phoremia by the following combination of characteristics: (i) distal portion of pseudepiphallic sclerite with rounded shape, when in ventral and dorsal view ( Fig. 15 A, B); (ii) ends of apical lobe not surpassing median lobe, when in ventral and dorsal view ( Fig. 15 A, B) and (iii) endophalic central sclerite with proximal ends bulged, when in ventral view ( Fig. 15 A).

Description. Holotype, male, measurements (mm): BL 8,57; MID 1,03; LP 1,42; MWP 1,96; MLF 4,25; MLT 3,0 0. Head dark yellow, showing dark brown spots on apex and forehead, covered with long black bristles on the median region, presence of fine and short light brown hairs covering all its extension; black eyes; three ocelli present, central ocellus surrounded on the superior and inferior border, by dark brown spot, lateral ocelli partially surrounded, on the internal border, by one dark brown spot each; antennal scape enlarged and dark yellow, antennal articles varying from light yellow (first articles) to light brown (last articles); gena black; clypeus dark brown on the superior portion and whitish on the inferior; labrum light brown; mandibles coloration varying from dark brown on the base to light brown on the apex; maxillary palpi coloration varying from light yellow to light brown with whitish not truncate apex. Pronotum dark yellow with diffuse dark brown spots, presence of fine and short light brown hairs covering all its extension; latero-inferior lobe black; row of long bristles present on anterior and posterior pronotum border; mesonotum dark yellow on the center with dark brown spots on anterior and lateral portion; metanotum coloration varying from dark yellow on the center and posterior portion, to dark brown on lateral and anterior portions. Abdominal sternites 2 – 8 dark brown with dark yellow spots on laterals edges, presence of the fine hairs; tergite 1 dark brown, presence of the four dark spots (two centrals and two laterals); tergite 2 with six black spots (four centrals and two laterals); tergite 3 – 10 varying from dark brown, with some dark yellow spots to almost totally brown without spots; presence of short dark brown hairs covering all tergites; cercus light yellow; supra-anal plate little sclerotized and light yellow, presence of long light yellow hairs on lateral and posterior portions; subgenital plate light brown on proximal portion to dark brown on distal border ( Fig. 14 B). Fore and middle legs showing dark brown femurs with some light yellow spots on dorsal face associated with long black bristles ( Figs. 1 A and 15A, C); tibiae dark brown to light yellow with black bristles; tarsomeres light yellow; tympanum absent on the fore tibiae; hind legs femur adorned with big light yellow spot and some diffuse light yellow spots merged with others light brown on all extension; hind tibiae light brown with two light yellow spots, presence of three apical spurs and three inner and outer dorsal spurs; tarsomeres light brown to light yellow. Male genitalia: Pseudepiphallus showing apical portion with rounded shape, when in ventral and dorsal view ( Fig. 15 A, B); ends of apical lobe not surpassing median lobe, when in ventral and dorsal view ( Fig. 15 A, B); apical lobes little sclerotized and parcially separate by a cleft when in ventral, dorsal and posterior view ( Fig. 15 A, B and D). Endophallus divided in three sclerites, being one central and two laterals ( Fig. 15 A, B and D); endophalic central sclerite longer than wide with proximal ends bulged, when in ventral view ( Fig. 15 A). Ectophallic apodeme crossing the rami, when in ventral, dorsal and posterior view ( Fig. 17 A, B and D). Female: Body shape very similar to male, showing only the following differences: sternites 2 – 6 with rectangular lateral spots, biggest the males, but more light; tergites 2 – 10 light brown covered by dark yellow spots. Subgenital plate dark yellow, adorned with central dark brown spot ( Fig. 14 D). Ovipositor dark yellow ( Figs. 14 C – D, 15E).

Measurements. Males (n=6, excluding holotype). BL 6,67 – 8,38 (7,73 ± 0,66); MID 0,93 – 1,0 3 (0,98 ± 0,04); LP 1,27 – 1,38 (1,33 ± 0,04); MWP 1,81 – 2,0 8 (1,96 ± 0,11); MLF 3,75 – 4,79 (4,0 9 ± 0,37); MLT 2,71 – 2,83 (2,78 ± 0,04).
