A new genus and species of cricket, Anomaloterga mantiqueirae, here described, is the first representative of Strogulomorphini to be reported from Brazil. The specimens were collected at night from the lower portions of live tree trunks in a summit forest located on the Mantiqueira Fault Escarpment, State of São Paulo.
Introduction
Desutter (1990) moved the Neoaclini and Strogulomorphini from the Neoaclidae to Phalangopsinae and extinguished the former family. In 1991, that author redefined the tribe Strogulomorphini and presented an identification key for the five genera of the tribe: 1) Strogulomorpha Desutter, 1988, with four species from West Amazonia (Loreto, Peru); 2) Loretana Desutter-Grandcolas, 1991, with one species from the same place; 3) Nigrothema Desutter-Grandcolas, 1991, one species from the same place; 4) Unithema Desutter-Grandcolas, 1991, one species from Guadalupe and two from French Guiana; 5) Eugryllina Hebard, 1928, with one species from northwest Colombia and another from Panama.
Here we describe the first genus of Strogulomorphini from Brazil and provide an identification key for the genera. We employ the terminology of Desutter (1990) for the phallic elements, with the corrections that author proposed in a more recent publication (Desutter-Grandcolas, 2003). The classification scheme proposed by Desutter (1990) is followed.
ANOMALOTERGA de Mello & Bolfarini, gen. n.
Type-species: A. mantiqueirae, sp. n.
(Figs 1–4)
Etymology.— The genus name refers to the abnormal shape of the male abdominal tergites.
Diagnosis.— 1) Intra-ocular space furnished with a dense cluster of thick bristles (not as dense on females); 2) dorsum of male abdomen bearing a distinctive specialization (see type species description below); 3) pseudepiphallus semitubular, dorsally bearing a pair of longitudinal carinae which delimit a broad and shallow sulcus; 4) each pseudepiphallic paramere with a pair of spines, the smaller one (spine1) located anteriorly and juxtaposed to the longer, posterior one (spine 2), the latter with its median-ventral portion expanded, touching its equivalent of the opposite side
Description.—Male: Head clearly triangular as seen from the front, its largest breadth at eye level; interantennal space much broader than scape; eyes large, bulbous, narrowing ventrally, without depigmented area on dorso-internal margin; three ocelli present, intra-ocular space furnished with a dense cluster of thick bristles; 5th joint of maxillary palpi expanded at the base of apical truncation, 4th joint short. Pronotum widerthan long, covered with bristles, anterior and posterior margins of disk straight; lateral lobes shorter posteriorly, anterior angle subacute, the posterior rounded; wings absent. Legs velvety, setose; tibia I without auditory tympana, furnished with a pair of ventral spurs, the external one longer and thicker than the internal; tibia II similar to tibia I, but with the internal apical spur longer than the outer; inner face of tibia III with three dorsal spurs and two apical ones, the inferior slightly longer; outer face of tibia III with 4–5 dorsal spurs and 3 apical ones, the median the longest. Dorsum of abdomen with a remarkable specialization (Figs 1E, F; 2E): tergite 3 with concave posterior margin and a pair of dorsolateral projections; tergite 4 with an even more concave posterior margin, without dorsolateral projections, but with a semicircular transverse carina; presence of a conspicuous tergal membrane between tergites 4 and 5; tergite 5 with a pair of lateral projections and a median bulbous hump, garnished with a cluster of delicate bristles; tergite 6 poorly differentiated from the posterior ones, but somewhat inflated laterally. Supra-anal plate short, rounded distally; subgenital plate subpentagonal, acuminate. Phallic complex elongate (Figs 3A, B, C, D); main lobe of pseudepiphallus semitubular, dorsally furnished with a pair of longitudinal carinae which delimit a broad and shallow sulcus; each pseudepiphallic paramere shaped as a pair of spurs, the smaller one (spur1) located anteriorly and juxtaposed to the longer, posterior one (spur 2), the latter with its midventral portion expanded, touching its equivalent of the opposite side; ectophallic apodemes long, rod-shaped, the arc located distally; endophallic sclerite elongate and poorly visible (little pigmented), its apodemes inconspicuous.
Female: Similar to male but somewhat larger. Dorsum of abdomen without specializations. Ovipositor stout, laterally compressed, upcurved distally, the apical valves tall.

Anomaloterga mantiqueirae
de Mello & Bolfarini, sp.n.
(Figs 1 to 4)
Etymology. —Toponimic, allusive to the Mantiqueira fault escarpment in southeastern Brazil.
Description.—Male: General aspect marmorate, with marbles in various shades of brown on a yellowish background; dorsum of head yellowish, glabrous, with four poorly defined light yellow maculae; eyes black; interocularspace with a broad, blackish transverse band, garnished with a dense cluster of black bristles; frons yellow with a brown line running from the inferior margin of each eye to the epistomal suture, and a pair of shorter brown lines originating on the sides of median ocellus (Fig. 2C); gena yellowish, with a light brown blurring along its posterior border and a brown, subfiliform, vertical macula, located between the posterior margin of the eye and the referred-to brown blurring; antennal scape yellow with brown blurring nearits apex; clypeus, labrum and base of mandibles yellow; 5th joint of maxillary palpi brown-blurred, mainly on the sides. Dorsum of pronotum, mesonotum, metanotum, abdominal tergites 1 and 2 irregularly mottled in several shades of brown, a thin, yellow median line (Fig. 2A) running along all these segments longitudinally; femora I and II yellow with brown maculae; tibia I and II with broad brown bands; femur III yellow with irregular brown bands on outer face (Fig. 2F). Dorsal and lateral faces of abdomen marbled, darker than sternites; supra-anal plate yellowish cephalad, its mid-distal portion blurred. Female: color patterns similar to that of male but somewhat more defined; dorsum of head with the four light brown maculae garnished with dark setae pointing to the front (setae absent on males); cluster of bristles on inter-ocular space not as dense as for the male; supra-anal and subgenital plates as in Figs 4B, C; ovipositor medium brown with darker apical valves; spermatheca as in Fig. 4E.
Material examined.— Brazil, São Paulo state, São José dos Campos, São Francisco Xavier district, Kolibri farm, ca 1,300 m alt., 10–23. iii. 2006, M. P. Bolfarini leg. Holotype male, 2 male, 9 female paratypes. Paratypes with same data as holotype. Holotype male and four female paratypes deposited at the Museu de Zoologia da universidade de São Paulo (MZSP); remaining paratypes kept at Departamento de Zoologia, Botucatu Campus of São Paulo State University (UNESP), Brazil.
