The Brazilian territory presents a great diversity of biomes, such as equatorial rainforest, cerrado and Atlantic Forest. As a reflection of this, there exists a great biodiversity of plants and animals, several species or groups of species being endemic, and in some particular circumstances, vectors of agents to man and other mammals, as in the case of the phlebotomine sand flies. However, with so many environmental modifications of an anthropic nature these environments have become less stable, leading to an expansion of the customary biomes of various diseases, generating diverse public health problems, such as the invasion of urban centers by leishmaniases.This study describes a new species of sand fly found in the Brazilian state of Espírito Santo (ES), in the Reserva Biológica de Duas Bocas (20 o 18'05''S and 40 o 28'06''W), municipality of Cariacica. The area is cover by Atlantic Forest, with an altitude of between 450-850 m above sea level.
MATERIALS AND METHODSSandflies were mounted in Berlese liquid and measured with a binocular Olympus CH-2 microscope with the aid of a micrometer objective and the drawings were made with the help of a camera lucida. The measurements are given in micrometers. The nomenclature and classification is that proposed by Galati (2003) and the abbreviation of the names for phlebotomine genera that proposed by Marcondes (2007). Male (holotype) -Sand fly of medium size, measurement ca. 3,038 (2,428 ± 75.7; n = 2) in length, general color light brown. Head (Fig. 1) 353 (349 ± 2.1; n = 2) long and 297 (301; n = 1) wide. Head length/head width ratio 1.19: 1 (1.16; n = 1). Clypeus 105 (111 ± 2.1; n = 2) long; clypeus length/head length ratio 0.30: 1 (0.32: 1 ± 0.01; n = 2).

Labrum-epipharynx (LE) 203 (184 ± 7.1; n = 2). LE/ head length 0.58: 1 (0.53 ± 0.01; n = 2). Antenna with simple, long ascoid, reaching the apex of the segment. Antennomere lengths: AIII 322 (286 ± 21.9; n = 2); AIV 147 (137 ± 14.8; n = 2); AV 154 (144 ± 9.9; n = 2); AXV > AXVI (AXV > AXVI; n = 2). AIII, AIV, AV and AXIII with papilla; ratios: AIII/head length 0.91: 1 (0.82: 1 ± 0.06; n = 2); AIII/LE 1.59: 1 (1.55: 1 ± 0.06; n = 2). Palpal formula 1.4.2.3.5 (1.4.2.3.5; n = 2). Palpomere lengths: P1 39 (34 ± 2.1; n = 2); P2 137 (139 ± 2.1; n = 2); P3 154 (160 ± 2.1; n = 2); P4 107 (114 ± 2.8; n = 2); P5 378 (337 ± 4.9; n = 2). The Newstead spines are implanted in the median region of the third palpomere. Ventrocervical sensillae present. Thorax: presence of two (1-2; n = 2) proepimeral setae and anepisternal superior setae 9-11 (10-12; n = 2) in number; setae on the anterior region of the katepisternum present. Wing (Fig. 3) measurement 2,953 (2,077; n = 1) long and 593 (558 ± 30.0; n = 2) at maximum width. Length/width ratio 4.97: 1 (3.73: 1 ± 0.20; n = 2). Length of the vein sections: R 5 1,272 (1,230 ± 39.6; n = 2); alpha 523 (509 ± 0.0; n = 2); beta 212 ...
