Zucchiella matiottiae Pereira, Sperber & Lhano , sp. nov.

( Figs. 20 , 21, 23A, 24)

Zucchiella sp. A in Sperber (1999)

Etymology. The specific epithet refers to Dra. Maria Kátia Matiotti da Costa, professor of Pontifícia Universidade Católica (PUC-RS) and Brazilian Orthopterologist.

Type. Holotype, male, Brasil, MG, Paula Cândido, “Córrego Reserva”, 16.xii.1993 (Sperber, C. F leg.). Diagnosis. This species may be distinguished from the other species of Zucchiella by the following combination of characteristics: (i) pseudepiphallic median lobe showing sub-straight margin, when in lateral view (Fig.

21C); (ii) distal margin of pseudepiphallic apical lobe sub-straight, when in lateral view (Fig. 21C); (iii) central endophallic sclerite with proximal ends rounded (Fig. 21A, B); (iv) pseudepiphallic sclerite with triangular shape, when in lateral view (Fig. 21C) and (v) ends of ectophallic apodeme crossing the rami, when in ventral, dorsal and posterior view (Fig. 21A, B and D).

Head orangish, showing light brown spots, 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, by light brown spot; antennal scape enlarged and light yellow, antennal articles varying from light yellow (first articles) to dark yellow (last articles); gena orangish; clypeus dark yellow on the superior portion and whitish on the inferior; labrum whitish on superior and light brown on inferior portion; mandibles coloration varying from orangish on the base to dark brown on the apex; maxillary palpi coloration varying from whitish to light brown with small dark brown spots. Pronotum dark yellow with two transverse dark brown spots, presence of long black bristles associated with fine and short light brown; latero-inferior lobe with light brown FIGURE 19.

Abdominal sternites 2 – 8 dark brown, presence of the fine hairs; sternites 5 – 8 with light yellow spots on laterals; tergite 1 varying from light brown on anterior to dark brown on posterior portion, presence of four dark spots (two centrals and two laterals); tergite 2 – 10 marbled varying from dark yellow to light brown with six black spots (four centrals and two laterals); presence of short light brown hairs covering all tergites and sternites; supra-anal plate litlle sclerotized and light yellow, presence of long light yellow hairs on lateral and posterior portions; subgenital plate light brown ( Fig. 20 B). Fore and middle legs showing dark yellow femurs with some light yellow spots associated with long black bristles ( Fig. 20 A, B); tibiae 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 six apical spurs (3 inner and 3 outer) and 4 inner and 4 outer dorsal spurs; tarsomeres light brown. Male genitalia. Pseudepiphallus enlarged on median portion, when in ventral and dorsal view (Fig. 21A, B); apical lobes little sclerotized and partially separated by a cleft, when in ventral, dorsal and posterior view (Fig. 21A, B and D); pseudepiphallic median lobe showing sub-straight margin, when in lateral view (Fig. 21C); distal margin of pseudepiphallic apical lobe sub-straight, when in lateral view (Fig. 21C); pseudepiphallic sclerite with triangular shape, when in lateral view (Fig. 21C). Endophallus with three robust sclerites, being one central and two lateral (Fig. 21A, B and D). Ends of ectophallic apodeme crossing the rami, when in ventral, dorsal and posterior view (Fig. 21A, B and D). Female: Body shape very similar to male, showing only the following differences: abdominal sternites varying light to dark brown, presence of laterals and centrals light brown spots, except on sternites 1 – 7; subgenital plate light yellow with anterior border and central portion light brown. Ovipositor varying from dark yellow on the proximal to light brown on distal portion ( Fig. 20 C, D and 21E).
