Sand Flies Of The Central Amazon Of Brazil. 3. Description Of Lutzomyia Pennyi N. Sp. (diptera: Psychodidae)

Notas & Comunicações Sand Flies of the Centra l Amazon of Brazil. 3 . Description of Lutzomyia pennyi n . sp . ( Diptera : Psychod idae ) ( *) Jorge R. Arias Rui A. de Freitas Instituto Nacional de Pesquisas da Amazônia, Manaus Early in 1979 we collected a new male form of phlebotomine sand fly, but did not describe it at the time because it was an only individual and was badly damaged. lt wasn't until early this year, two years after the origi-nal capture and 100 km west of the original site, that we again found this species: four males were taken (again in a coe miniature líght trap), and it is these that form the basis of the following description. Lutzomyia pennyi is named after Dr. Nor-man D. Penny, who has dedicated years of this life to entomological studies in the Amazon. The terminology follows that of Young (1979). The description is based on the holoty-pe with the ranges of some measurements of four paratypes given in parenthesis. Measure-ments are in millimeters. Ali sand flies are mounted in Berlese solution. each specimen was previously treated with hot KOH for ten minutes and immediately passed to phenol for initial identlfication. The Berlese preparations were ringed with clear fingernail polish. Figures 1, 2 and 5 were drawn from mounted material while figures 3.4 and 6 were drawn from a specimen in phenol. Lutzomyia penny i Arias & Freitas sp. n. Fig. 1. 6 Mate : A large pale sand fly; notum and pleura unpigmented, straw yellow in color. wing length 1.87 (1.81 -1.98); width 0.50 (0.49- 0.53). Cibarium without teeth remnants. cibarial arch complete, no pigment patch visi-ble . Pharynx O. 19 unarmed. Head height about 0.33 (0.30- 0.33); width 0.31 (0.29- 0.30). Eyes large, separated by O. 12 or by distance equal to 7. 2 facet diameters. Flagellomere I, O. 45 (0.39- 0.44) , combined length of 11 + 111 sub-equal to siightly longer than that) of I. Ascoids without posterior spurs, the distai tips of ascoids on 11 not reaching beyond flagellomere. Labrum 0.19 (0.15-0.19) long. Length of palpal segments (holotype): 1 (O. 04), 2 (0. 07).) 3 (0.12), 4 (0.07), 5 (0.15). Pleura with 10 (9-10) upper and 1 (1 ,2) lower episternal setae. Length of wing vein sections: alpha 0.46 (0.38- 0.47). beta 0.20 (0.17-0.20), delta 0.17 (0.09-0.17), gamma O. 34 (0.31 - 0.32). Length of femur. tí-bia and basitarsus of one paratype: foreleg, 0.88, 1.29, O. 77; midleg 0.86, 1.52, 0 .84; hindleg missing . Genitalia: style O. 27 (4.25-0.27) long with four major spines arranged as shown, no subterrr11nal setae. Coxite O. 39 (0.35- 0.38) long 0 .07 (0.07) wide, bearing a basal medían group of -;ix surong thick hairs implanted on a prominent tubercule ; both the tubercule and the h.airs oriented upwards, as figured, parallelíng the coxite. Paramere as shown. Aedegus moderately pigmented, as drawn. Genital pump 0.19 (0.18-0.19) long, each filament 1.31 (1.25 -1.47) long or 6.8 (6.6- 7.8) X length of pump, tips simple.

DrsCUSSION Lutzomyia penny does not fit into any sub-generic group of sand flies as defined by Theodor (1965) or Martins et ai. (~978). Even though this species shares many characters with those in the species group gasparviannai the fifth palpal segment is shorter than the combined length of the third and fourth, the coloration is much paler, the paramere is more complex, the geniial filament/ pump ratio is higher, and the coxite tuft is implanted in a sclerotized rather than a fleshy tubercule . Therefore, for the present time, we prefer to leave this as an ungrouped species. Recently Arias & Freitas (1981) published a 13 month sand fly survey in which over 20,000 sand flies were captured only three km from the last site where this species was taken. Hundreds of other CDC l ight trap catches at various heightsfrom the forest floor, as well as flight trap, Disney trap and emergence trap catches have been examined within a 50 km radius of this srte during past seven years and this species was not taken, indicating th~ rarity of collectons of L. pennyi in this region. We wish to thank Mr. João Ferreira Vidal for his assistance in the field and the labora· tory, and the command of the 1.0 BIS (First Jungle lnfantry Batalion) for their support.
