Length 5.35mm; width a$oss hume¡i: 1.75 mm.Material examined: Holotype, male: SURINAM, Saramacca, coesewijne-project, 12 km. w. ofSaramacca-brug, sN 368, lrr-24-'19, N. NIESER (uM). Paratypes: I ó, 3 99, BRAZIL, Amazonas, ReservaDucke, 25 km. NE of Manaus, 120 m,Ylr-22-73, R. T. scHUH, from marginal vegetation in impondedsection of forest stream (AMNH, JTP).Etymology: The name dilatøta ¡eîers to the bizarre anteriorly êxpanded pronotum of the maleof this species.Discussion: The peculiar male pronotal f orm of Poravelía dilatata n. sp. immediately separates it:::i.* othet Paravelía species. The large size and pallicl fourth antennal segment are diagnostic for both498Genital segment brown, covered with fine gold setae; longer fuscous setae prcsent near bases ofparameres; parameresgently curved, slender, ends rounded, shape as in Figure 2.Macropterous Female: Similar to male in general structure and coloration but larger and morerobust; wings longer, exceeding tip of abclomen.Material examined: Holotype, male, and allotype, female: BRAZIL, Amazonas, Rio Marauiá,l-26-63, A 500, E. J. FITTKAU(PIön). Paratypes: 8 ód, 4 çQ, same data as types (JTp, WC).Etymology: The name foveatø rcfers to the numerous shallow hair free fovea on the pronotumand atidomen of this species.Discussion: Paraveliø foveata n. sp. resembles P. hunserfordí DRAKE & I{ARRIS in that bothspecies have numerous hair f¡ee fovea on the pronotum and venter of the abdomen. The entire dorsumof P. hungerfordi is set with setae longer than the width of the first antennal segment whereas P. foveatøhas only scatte¡ed short upright setae and the dorsum is essentially hair-free. The foveae on the bodyseparate these two species from all other known Paravelia species. P. hungerfordí is known to us only bythe female paratype in the DRAKE Collection so a comparison of male genitalia is not possible.499Paravelia cupøriana n. sp.DescriPtionMacropterous male: Small, elongate, broadest across humeri; general coloration orange brownwíth scattered lighter patches.

Legs yellow, apices offemora, basesand tips of tibiae, and tarsi embrowned; all segments clothed with recumbent gold setae; femora andtibiae with long upright fuscous setae; fore tibia with black raised ridge apically; proportìôns of legs asfollows:Femur II Tarsal IIIParavelía juruanø n. sp.DescriptionMacropterous male: Of moderate size, robust, broadest across humeral angles of pronotum;general coloration dark brown with scattered white spots on hemelytra.

Lergth 3.51 mm; maximum width 1.37 mm.Material examined: Type, male, and allotype, female: BRAZIL, Pará, Rio Cupari, Igarape Prainha,S 209, XII-25-47, H. SIOLI (Plön). Paratypes: I ó, I ç, same data as types (JTP).Etymology: The name cupariana derives f¡om the type locality, the Cupari River, a right tributaryof the Rio Tapajós, state of Pará.,BrazilDiscussion: Paravelía cupariana n. sp. belongs to the group of small Paravella species that lackevident modifications (spot characters) that immediately distinguish them. Further, this species lacks theclosely set short black conical setae on the head, pronotum and connexival margins that characterize anentire group of congeners, although the dorsum is thickly set with slender setae longer than the width ofthe first antennal segment. The first antennal segment is clearly longer, and the fourth antennal segmentclearly shorter, than the width of the head. These characters along with the coloration and male genitalcharacteristicsgiven in the description will separate this species from any desqibedParaveft? species. Theclosest congeners arc Pøravelía cognata DRAKE & IIARRIS and Paravelia capíllata DRAKE & HARRISwhich both have the fou¡th antennal segment muih longer than the head width.500Genital segment brown, set with fine gold setae; parameres small, ovate, shape as in Figure 5Macropterous female: Similar to male in general structure and coloration. Length 5.71 mm;maxirnum width 2.08 mm.Material examined: Holotype, male, an<l allotype, female: BRAZIL, Amazonas, Vic. Joao Pessoa(Sao Phelipe),Rio Jurua,VII-10 to lX-20-1936,#3796,A. M. OLLALA (KU). Paratypes: 8 ód,7 çç,same data as types (KU, JTP).Etymology: The name iuruana de¡ives from the type locality, the Jurua River of Brazil.Discussion: Paravelia iuruana n. sp. is loosely allied to the previous species (P. cupariana n. sp.)in that it lacks ventral processes on the male seventh sternite, lacks minute conical setae on the body,has a hairy dorsum, and has a fourth antennal ssgment that is shorte¡ than the width of the head, butdiffers in that the first antennal is shorter than the width of the head and in being much larger thancupøriqna. The pronotum is acuminate posterioriy which immediately separates 7u ruana ftom allParøvelia species that lack the male ventral processes.501References'.LHEMUS, J.
