The A. and his co-workers captured in trips in the hinterland of Brazil more than 17.000 flebotomi from which 35 are new ones, 11 described by, him in previous papers. The A. found these insects in groups of species living in different habitats, some ones of them not yet known: ondoors, or outdoors attracted by light or animal baits, without Shannon’s trap, in great or small caves, in the jungle in tree’s holes, holes in stones, holes in the soil habited by animals like armadillos, pacas (Aguti paca), wild rats, cururú toad (Bufo sp.). He observed the life history of 13 species: Flebotomus longipalpis Lutz & Neiva, 1912, Flebotomus intermedius Lutz & Neiva, 1912, Flebotomus avellari Costa Lima, 1932, Flebotomus aragãoi Costa Lima, 1932, Flebotomus lutzianus Costa Lima, 1932, Flebotomus limai Fonseca, 1935, Flebotomus rickardi Costa Lima, 1936, Flebotomus dasipodogeton Castro, 1939, Flebotomus oswaldoi n. sp., Flebotomus villelai n. sp., Flebotomus triacanthus n. sp., Flebotomus longispinus n. sp. and Flebotomus travassosi n. sp. He describes the male of 24 n. sp., explaining the differential diagnose of group of nearly allied species. He included F. rooti n. sp. and F. hirsutus n. sp. in the subgenus Shannonomyia. The first one, very allied to F. davisi Root is different from it, for presenting in the dorsal side of the abdomen bristles and not scales and to have the median claspers longer than his inner appendage and F. hirsutus quite different from the others which show 3 spines on distal segment of the upper clasper and for being the only one who presents the bristles of inner appendage of median clasper longer than it. Only the females of F. amazonensis Root and F. chagasi Costa Lima, are known and then it is possible that they belong to one of the species of this sub-genus from whom only the male have been described. F. choti Floch & Abonnenc, captured also at Pará, F. triacanthus n. sp., F. trispinosus n. sp. and F. equatorialis n. sp. are very related and to this group the A. proposes the name of Pressatia as sub-genus in honor to whom demonstrated the medical importance of the flebotomi, considering F. triacanthus as the type specie of this subgenus. In this sub-genus the V papal joint is very long, longer than III + IV, the antennae with geniculated spines without posterior outgrowth. At the genitalia the basal segment of the upper clasper presents two types of bristles on the inner face, arranged in tuft; the distal segment with 3 spines and 2 thin bristles something difficult to see one of them situated near the apical spine and the other on the base of tubercle where the median spine is articulated; the median clasper is unarmed and compressed; the inferior clasper is also unarmed and longer than de basal segment of the upper clasper; the pompêta is longer than the basal segment of the upper clasper. Following it is presented a key for the determination of the males of the four species of this sub-genus. F. micropygus n. sp., F. minasensis n. sp. e F. dandrophylus n. sp., F. shannoni, F. monticolus, F. pestanai, F. lanei and F. cayenensis constitute a group with many similar characters. F. micropygus is the only American species who present á smaller than â and for that reason and others is allied to F. minuts and others related species, but presents two terminal spines on the distal segment of the upper clasper. F. micropygus and F. minasensis are quite different because they have very small genitalia, smaller than their heads. F. dendrophylus presents on the median clasper a naked area near the apex and for this and others characters is different from the others of the group. F. flaviscutellatus n. sp., F. oliverioi, F. intermedius and whithmani, are very allied but the first one can be very easily distinguished because it’s scutellum is light. Flebotomus barrettoi n. sp., F. coutinhoi n. sp., F. aragãoi, F. brasiliensis, F. lutzianus, F. texanus, F. pascalei, F. atroclavatus and F. tejeraae are very allied forming a natural group. The two last ones are not well known but the A. A. who have studied them described very long clipeus so long as the head and for that reason can be distinguished from all the others included the two new ones. F. coutinhoi is the only one who presents the apecis of the penis filaments twisted. F. barrettoi n. sp. can be distinguished from aragãoi, texanus and coutinhoi by the lenght of the penis filaments and from atrocavatus, tejeraae, lutzianus and brasiliensis by the arrangement of the spines of distal segment of the upper clasper. Flebotomus ubiquitalis n. sp., F. auraensis n. sp., F. affinis and F. microps e F. antunesi have many common characters. F. microps n. sp. can be distinguished from any one by the size of the eyes and the presence of well developed genac. This species and other new species are different from F. antunesi by the arrangement of the spines of the distal segment of the upper clasper of the latter. F. ubiquitalis n. sp. can be distinguished from others by the figure of the median clasper. F. auraensis n. sp. can be distinguished from F. affinis n. sp. by the tuft hairs on the inner face of the basal segment and by arrangement of the spines of the distal segment of the upper clasper. Flebotomus brachipygus n. sp. seemed to be F. rostrans, specie not well known, by the characters of the genitalia but can not be identified to her by the clipeus size and the palpi’s characters. Flebotomus costalimai n. sp., F. tupynambai n. sp. and F. castroi Barretto & Coutinho, 1941, are very allied species and the A. proposes to include them in the new sub-genus Castromyia, in honor to Dr. G. M. de Oliveira Castro, appointing like type-species F. castroi with the V joint longer than III + IV; antennae with geniculated spines without posterior prolongation. Genitalia: the basal segment of the upper clasper with a tuft of hairs and the distal segment with 4 spines, one of them at the apex and near it a thin and straight bristle difficult to see; the median clasper with one spinous hair isolated on the middle of the upper face of the lower clasper, is of the same size or longer than the basal segment of the upper. The A. presents a key for the determination of the males of the 3 species of this sub-genus. Flebotomus longispinus n. sp. is related to F. dasipodogeton Castro 1939, from which can be distinguished by absence of discous appendage of the gubernaculum. Flebotomus peresi n. sp., F. oswaldoi n. sp. and F. villelai n. sp. have 5 spines on the distal segment of the upper clasper. Excepting the species of the sub-generi Brumptomyia and Shannomyia, like it is presented in this paper, there are more the following: F. vexator, F. trinidadensis, F. sordellii, F. noguchii, F. peruensis, F. quiquefer, F. yucatanensis, F. rickardi and the 3 new species above referred. The A. explain the differential diagnoses for them. Flebotomus travassosi n. sp. and F. cunhai n. sp. belong to the sub-genus Brumptomyia França, for which the A. proposes a new diagnose and remembering that F. brumpti is the types species. The A. exposes the differential diagnose for new species and the other of this sub-genus which are the following: F. brumpti, F. troglodytes, F. nitizulescui, F. pintoi, F. avellari, F. cardosoi, F. mangabeirai, F. guimarãesi, F. travassosi n. sp. and F. cunhai n. sp.
