CB Marcondes (1996 Mem Inst Oswaldo Cruz, 91: 457-462) proposed the revalidation of Lutzomyia neivai (Pinto, 1926) which,together with L. intermedia s. s., would form the L. intermedia complex. Insects of this complex have been reported in Brazil, Argentina and Paraguay [DG Young & M Duncan 1994 Guide to the Identification and Geographical Distribution of Lutzomyia Sand Flies in Mexico, the West Indies, Central and South America (Diptera: Psychodidae), Mem Am Entom Inst 54, 881 pp.], and have been incriminated as vectors of dermal leishmaniasis in São Paulo (OP Forattini et al. 1976 Rev Saúde Públ 10:31-43, AC Gomes et al. 1983 Rev Saúde Públ 14:540-556) and Rio de Janeiro (e. g., EF Rangel et al. 1990 Mem Inst Oswaldo Cruz 85:39-45). However, FA Squire (1972 Pest Art News Summ 18: 249-268) and F Le Pont et al. (1992 Leishmanioses et Phlébotomes en Bolivie, ORSTOM Ed., 116 pp.) mentioned the presence of L. intermedia in Bolivia.

Recently, CB Marcondes (1998 Rev Soc Bras Med Trop 31: 51-58) studied the geographical distribution of this complex, and identified all specimens from the State of Paraná, west of the State of São Paulo, Paraguay, Argentina and Bolivia as L. neivai.

We got 39 measurements [1997 Morfometria e DNA Mitocondrial de Populações Sul Americanas de Lutzomyia intermedia (Lutz & Neiva, 1912) (Diptera, Psychodidae, Phlebotominae), PhD Thesis, Univ. Fed. Paraná, xxiv+260 pp., p. 57, 59] from one male and 14 females of L. neivai from Bolivia. The insects were collectedin Fortin Campero, near Bermejo (22o11'S 64o38'W), Tarija Department, southern Bolivia. The region has sandy soil, the vegetation is low and the dry season is very short (900-1500 mm/year). Collections were made in a gallery forest in the foot of the last hills of subandean area, called "Argentine Yungas". Based on extensive studies in the region, this was the only species found and it is very aggressive to man.

Insects identified as L. neivai (Marcondes 1997 loc. cit.)were suspected as vectors of parasites of dermal leishmaniasis in a nearby region of Argentina (OD Salomón et al. 1992 Rev Inst Med Trop S Paulo 37: 91-92) and its importance in Bolivia as a vector needs to be studied.

The fork between R2 and R3 of both wings of one female was much near the tip to the wing than usual in other insects of the complex (cf. ca. 750 specimens measured). The distances in her wings, compared to the wings of other females from the same locality, are shown in the Table.

HH Taniguchi et al. (1992 Rev Inst Adolfo Lutz 52: 105-106) described a female of L. intermedia (actually L. neivai) from São Roque, in the State of São Paulo, with three spermathecae, and many other authors described several different anomalies in other species (e. g., MP Barretto 1943 Rev Med Cir Bras 51: 703-710, Floch & Abonnenc 1944 Inst Pasteur Guyane fr 95: 4, A Dampf 1945 Bol Entomol Venez 4: 153-159, JF Azevedo 1946 An Inst Med Trop Lisboa 3: 183-186, OP Forattini 1954 Folia Clin biol 21: 353-356, IA Sherlock 1958 Rev Bras Biol 18: 433-437, E Abonnenc et al. 1971 Cah ORSTOM sèr Ent Med Parasitol 9: 307-316, DG Young & JR Arias 1982 J Med Entomol 19: 134-138, F Morillas-Marquez et al. 1983 Rev Ibér Parasitol 43:135-144, JP Dedet et al. 1984 Cah ORSTOM sèr Ent Méd Parasitol 22: 99-127, D Cazorla et al. 1988 Bol Dir San Amb 28: 91-98, B Geoffroy 1984 Cah ORSTOM sèr Ent Méd Parasitol 22: 257-260, RHP Moraes & RMO Veiga 1988 Mem Inst Butantan 50: 41-46, J Adhami 1991 Parassitologia 33: 169-173). However, only JA Sinton (1925 Ind J Med Res 12: 467-470, 1927 14: 947-953) described wing anomalies in sandflies. More detailed studies on specimens from several localities should be developed, to clear the frequencies of these anomalies and the possible relationship with genetics and environment.
