A largesurvey on ectoparasites of many thousands little mammals, mainly rodents, by the National Plague Services is in course in the northeast Brazil. Results of the identification of the acaro-fauna from 1549 classified hosts, from a series of 2635 mammals, is presented in Tabes I and II. A total of 2313 lots was obtained from identified hosts, belonging to four families: Argasidae, Ixodidiae, Macronyssidae and Lealaptidae. Nine new and twenty two older species were found in this survey, their distribution throught twenty three hosts being shown in two tables. The local fauna of parasitic Acari and the absence of Trombiculidae, Sarcoptidae, Cavilaelaps braziliensis (Ewing) and Dermanyssus brasiliensis Fonseca are commented. Literature on the transmission of Plague by Acari is reviewed. The host of the adult female of Ixodes amarali Fonseca, 1936 was discovered to be the marsupial Manodelphys domestica, ticks being found in 25 out of 49 animals, males remaining unknown. For Laelaps mazzai Fonseca, 1939 the new genus Schizolaelaps is proposed, with following diagnosis: Laelaptidae; female with a laclaps like genito-ventral plate and many suplementary setae in the dorsal shield; male with separated sterno-genito-ventral and anal plates and dorsal shield densely beset with setae. Genotype: Laelaps mazzai Fonseca 1939. The number of the setae in the dorsal shield is the main distinguishing character from Hyperlaelaps Zachvatkin 1948. The first Androlaelaps species from South America, androlaelaps foxi sp. n., is described from Zygodontomys pixuna of Comorango, Pesqueira, Pernambuco and from the same host of an unknown locality of northeastern Brazil. Sternal plate 87 by 12 micra; tritosternum setous from the bifurcation. Genito-ventral plate about 155 micra wide, with 46 micra long genital setae. Anal plate as long as wide, with 100 micra, the paired setae longer. The two posterior pairs of submedian setae of the dorsal shield are the longest. Only leg I is enlarged; spines of this leg as show in fig. 54 Atricholaelaps (Atr.) guimaraesi sp. n. from Hesmorys sp. of northeast Brazil was seen pnce; idiosoma 858 by 665 micra; sternal plate 130 by 155 micra. Anal plate 130 by 135 micra, with paired setae almost at the level of the middle of the anus and half as long as the unpaired one. Dorsal shield with comparatively short submedian setae. Atricholaelaps (Atr.) willmanni sp. n., type host Zigodontomys pixuna from Triunfo, Pernambuco, was also captured on Oryzomys subflavus, Heliurus sp. and Monodelphys domestica; it differs from. A. guimaraesi by the longer dorsal and paired anal setae. Atricholaelaps (Ischnolaelaps) keegani sp. n. from Oryzomys subflavus of northeast Brazil, has an 840 micra long idiosoma; sternal plate 490 by 574 micra; metaesternal setae shortest than the smaller ones of the sternal plate; genito-ventral plate small, only 130 micra long from the basis of the genital setae to the middle of the posterior border, by 130 micra wide, with 125 micra long genital setae; anal plate 145 micra longe by 126 micra wide paired setae with 83 and unpaired one with 90 micra; pilus dentilis inflated basaly as in all species of this subgenus Gigantolaelaps strandtmanni, sp. n., with Nectomys squamipes amazonicus from Vigia, Para, as type host, has been captured on Holochilus sciureus from Ca ruaru, Oryzomys cliurus from Garanhuns, both in Pernambuco and on unknown host from Vicosa, Ceara; it belongs to the group with two spines on coxa I and a posterior spine on coxa II and III; it differs from G. goyanensis Fonseca by a somewhat cocave posterior margin of the dorsal shield; from G. mattogrossensis it is distinguished by a much smaller unpaired anal reta; from G. cricetidarum Morlan in differs by its longer size, by a longer size, by a longer posterior seta on coxa II and by the more pronounced anterior projetion of the sternal plate. Gigantolaelaps canestrinis sp. n., is described from four female cotypes captured on "Tree rat" from unknown region of Brazil; in the northeast it has been obtained from Oryzomys subflavus, Oryzomys cliurus and Proechimys albispinus at Garanhuns and Caruaru, Pernambuco, as also from "Gravata rat" at Juquie, Bahia. This species has a total lenght to the apex of the palpi of 1879 micra; from the coxae only that of the third pair of legs has true spines; tarsus 11 with very strong spines. Laelaps castro, sp. n., has an idiosoma of 670 micra and closely approaches L. paulistanensis Fonseca, L. manguinhosi Fonseca, L. differens Fonseca and L. exceptionalis Fonseca. L. castroi differs from the firrst of these species by the smaller size and wider, shorter, pointed proximal spine of coxa I; from manguinhosi it differs by the very short posterior gnathosomatal setae on this species; from differs it is distinguished by the very short and strong, only 18 micra long anterior vertical setae; from exceptionalis it is easely distinguished by the subequal anal setae in this species. As type material they were selected eigh females captured on Oryzomys eliurus at Torres, Caruaru, Pernambuco. The same species was seen in nine other identified rats from Bahia, Pernambuco, Alagoas and Ceara and on Graomys griseoflavus and Dasyprocta variegata from Buen Retiro, Bolivia, the last one a quite unexpected host for a true Laelaps. The male remains unknow. Tur turki sp. n., is described from the female holoty obtained from a Proechimys inheringi denigratus of undetermined region of northeast Brazil. Idiosoma 714 micra long; sternal plate 165 micra long with an arched posterior border. Genito-ventral plate long and wide with a shallow posterior border to acommodate the anterior border of the anal plate, as in the echidninus group. A membranous expansion is seen between the finger of the mandibles much in the same way as in L. lateventralis Fonseca. Mysolaelaps heteronynchus, sp. n., is prevalent on rats of the genus Rhipidomys, type material being from Rhipidomys mastacalis from Quandu, Caruaru, Pernambuco; other hosts from Brazil as in tables I and II. The species was also obtained from Graomys griseoflavus and Oxymicterus doris from Agua Hedionda and from Graomys griseoflavus from Floripondio and Nivillos in Bolivia. It is the largest species of this genus, with a 1500-1700 micra long idiosoma, the most strinking characters being the unequal claws on tarsus II to IV as shown in the fig 31; onlythree pairs of setae are implanted directly on the genito-ventral plate; as in other species of this genus males were not found. Following diagnosis is proposed for the genus Mysolaelaps Fonseca 1936: Laelaptidae; large, more than 1200 micra long species; all chitinised areas of a deep colour; dorsal shield very regular in outline, only the marginal and the vertical setae being long; coxa devoided of true spines; setae of the idiosoma frequently short and if long they are flexible; genitoventral plate very long and very wide, with four or three pairs of setae; penitrem don't exced coxa II; anal plate weak, wider than long, the anus at a shorter distance from the anterior border athan its lenght; only females are found on wild rats. Genotype: Mysolaelaps parvispinosus Fonseca 1936. Drawings of older species published without figures are presented. Preference or avoidance of some hosts are clearly deduced from the data obtained from 1549 rodents and marsupials as shown in tables I and II.
