Cyrtosoma cearense sp. n. (Fig. 1) Description - Wingless, convex both longitudinally and transversely (Fig. 1); black, elytra and ventral surface shining, antennae, mouthparts and legs ferrugineous. Head subrectangular, transverse minutely and densely punctate; clypeus truncate, frontoclypeal suture shallow; genae well developed, slightly convex, rounded; eyes large and rounded, surpassing width of genae. Antennae rather short, club well developed, formed by four antennomeres, antennomere 11 as long as broad, 8 to 10 transverse. Last palpomere of maxillary palps very large. Pronotum transverse, slightly convex, gently narrowed toward base; anterior angles very prominent, posterior angles obtuse; sides of pronotum with two small angulositics, deeply separated from anterior angles. Base only slightly broader than apex; pronotal surface with rather dense, minute punctation. Elytra very convex, subovate, apex slightly acuminate; elytral base broader than pronotum; humeral callus not prominent; striae replaced by rows of large and deep pits, regular in basal 2/3, rather irregular toward apex, where becoming foveate and tending to be confluent; interspaces smooth and shining; epipleura very broad at base, where excavated, then rapidly narrowed toward apex, where scarcely visible. Femora compressed; tibiae gently curved, tarsi rather short and thick, plantar surface with thick, short, black, slightly pad-like pubescence. Ventral surface smooth and shining; prosternai process short, lanceolate; mesoand metaventrite very short, abdominal ventrites smooth, shining, only two first ventrites showing minute punctation toward sides. Length 9.5 mm. Type material - Holotype, sex unknown (HNHM): "Ceara Brasilia"; "Cyrtosoma sp. det. Kaszab". Distribution - North-eastern Brasil, near Fortaleza, a region belonging to the so-called "dry horn" due to the relatively arid climate of this part of the country. Remarks - This species is very distinctive because of the absence of elytral striae that are replaced by rows of large, deep pits. Near the apex the foveae are tending to be confluent - this feature is extremely rare among species of Cyrtosoma. Cyrtosoma elvirae sp. n. (Fig. 2) Description - Wingless, very convex (Fig. 2); black, labrum and first antennomeres dark ferrugineous. Head transverse, smooth; clypeus truncate, frontoclypeal suture distinct; genae well developed, slightly convex; eyes rather large, somewhat transverse, slightly wider than genae; antennomere 11 longer than broad, 7 to 10 transverse. Pronotum transverse, much broader than head, more convex transversely than longitudinally, apex slightly broader than base; sides slightly rounded, maximum width at middle, where border forming a minute angulosity; anterior angles rounded, posterior angles obtuse; anterior, lateral and posterior margins bordered; pronotal surface smooth. Elytra very convex both transversely and longitudinally, very steep toward apex in lateral view; basally not broader than base of pronotum, ovate, with maximum width near middle, then gradually narrowed toward apex, which rather acuminate; striae well-developed throughout whole length, slightly more shallow medially on disc, deeper toward the sides and apex, so interstriae flat on
