Kempnyia pinhoi sp. n.

( Figs. 22-29 )

Material examined. Holotype, ♂, BRAZIL, Santa Catarina, Florianópolis, Unidade de Conservação Ambiental Desterro ( UCAD), 20/11-21/12/2003, Malaise trap, L.C. Pinho . Paratypes: 1♀, same data as holotype but 24/10-24/11/2003 ; 1♀, same data as holotype ( MZSP) .

Adult habitus. Small and dark species. Central frons ( Fig. 22 ) dark brown, M-line a shade lighter. Genae and parietalia brown, area on sides of coronal line lighter. Antennae brown. Pronotum brown, broad mid stripe yellowish. Wings infuscated, veins brown, C, Sc paler; 1-3 extra crossveins in distal half of forewings, none in hindwings. Legs brown, femora bicolored. Cerci ringed.

Male. Forewing length, 8.5 mm. Basiconic sensilla of tergum 10 short-elliptical ( Fig. 24 ). Paraprocts flattened distally, with a low subapical tooth and minute sensilla ( Fig. 25 ). Length of projecting part of subgenital plate slightly less than half its breadth; subgenital plate whitish, mid stripe pale brownish ( Fig. 23 ). Hammer elongate, broader apically. Penial armature broad in dorsal/ventral views, distally, conspicuous lateral flanges ( Figs. 27-28 ). Anterior foramen large, rim elevated ( Fig. 29 ). Hooks stout and short, bent inwards.

Female. Forewing length, 11.9 mm. Subgenital plate ( Fig. 26 ) with the deep, constricted notch, characteristic of the serrana -group of Kempnyia ( Froehlich 1984) .

Remarks. Kempnyia pinhoi is most similar to K. mirim Froehlich (1984) . Both species are of similar size, but K. pinhoi is darker than K. mirim ; in the penial armature, the dorsal rim of the foramen is higher in K pinhoi and the hooks of K. mirim are bent more laterally.

Etymology. The epithet honours Luiz Carlos de Pinho, specialist in Chironomidae and collector of the specimens.
