Abstract
U
Lutzomyia migonei is incriminated as a vector of Leishmania braziliensis, the main
N
causative agent of cutaneous leishmaniasis in Brazil. Recently, this phlebotomine sand
A
fly species has been suggested as a vector for Leishmania infantum, which causes
M
zoonotic visceral leishmaniasis. Considering the widespread distribution of Lu. migonei in South America, the existence of isolated populations has been hypothesized. Three Lu.
ED
migonei populations, two from north-eastern Brazil (Machados, Pernambuco State, and Baturité, Ceará State) and other from the south-eastern region (Niterói, Rio de Janeiro
PT
State) were analysed both morphologically and genetically. Though no significant
CC E
morphological differences were found amongst the sand fly specimens analysed, discriminant analysis based on specific morphometric characters (i.e., length of wing, antennal segment 3 and coxite for males, and length of wing and antennal segment 3 for
A
females), showed that specimens from Machados were closer to Baturité than to Niterói. The molecular analysis of cytochrome c oxidase subunit I gene sequences also supported this observation by the distinct separation of two monophyletic clades, grouping specimens from Machados and Baturité separately from those of Niterói. Our results suggest the existence of different populations within the distribution range of Lu. migonei.
Whether these populations are reproductively isolated and/or present differences in terms of vector competence/capacity for L. braziliensis and L. infantum needs to be further investigated.

1. Introduction
Phlebotomine sand flies are vectors of several disease agents, including protozoan
U
parasites of the genus Leishmania, which may cause a group of diseases generally referred
N
to as leishmaniasis. Out of ~1,000 sand fly species known to date, less than 100 have been
M
humans (Maroli et al., 2013).
A
regarded as proven or putative vectors of Leishmania spp. causing disease in animals and
ED
Studies have demonstrated that some sand fly species display remarkable specificity for the Leishmania spp. that they transmit and are referred to ‘specific vectors’. This is
PT
the case of Phlebotomus papatasi and Phlebotomus sergenti, the vectors of Leishmania major and Leishmania tropica, respectively (Kamhawi, 2006). On the other hand, most
CC E
sand fly vectors tested to date support the development of multiple Leishmania spp. and are referred to as ‘permissive vectors’ (Volf and Myskova, 2007). As an example,
A
Phlebotomus arabicus is a vector of L. tropica (Jacobson et al., 2003), but is highly susceptible to both L. major and Leishmania infantum (Myskova et al., 2007). Incidentally, L. infantum is a species that may develop in different sand fly species. In the Neotropical region, this parasite is primarily transmitted by Lutzomyia longipalpis, although other sand fly species have been regarded as putative vectors in different
countries (Brazil et al., 2015). For instance, a recent study has demonstrated the development of metacyclic promastigotes (infective forms) of L. infantum in Lutzomyia migonei (Guimarães et al., 2016), confirming the role of this sand fly as a permissive vector. Lutzomyia migonei is also considered to be a vector of Leishmania braziliensis, based on both field (Queiroz et al., 1994) and laboratory evidence (Nieves and Pimenta,
IP T
2000). This sand fly is widespread in South America, occurring in Argentina, Bolivia, Brazil, Colombia, Paraguay, Peru, Trinidad and Tobago, and Venezuela (Shimabukuro et
SC R
al., 2017).
The occurrence of differentiation and speciation due to geographical isolation and local adaptation has been hypothesized for different sand fly species, including Lu.
U
migonei (Vigoder et al., 2010a). However, to our knowledge, no morphological,
N
morphometric or molecular analyses have been provided to assess the existence of
A
different Lu. migonei populations in South America. In this context, we assessed
ED
geographical locations in Brazil.

2. Materials and methods 2.1. Sand fly collection
CC E
Lutzomyia migonei were collected in three different municipalities in Brazil (Fig. 1):
Machados, Pernambuco State (north-eastern Brazil) (07º41’09”S, 35º30’54”W); Baturité,
A
Ceará State (north-eastern Brazil) (04º19’44”S, 38º53’06”W), and Niterói, Rio de Janeiro State (south-eastern Brazil) (22º52’58”S, 43º06’14”W). Machados is a highland, situated 416 metres above the sea level. It possesses a tropical climate (As type) and most of its original vegetation coverage has been replaced by crop plantations, particularly banana
trees. The average annual temperature is 23.5C and average annual precipitation is 1,197 mm. Baturité is situated 175 metres above the sea level and the climate is tropical (Aw type). The hills are mainly covered by Atlantic forest remnants, surrounded by caatinga. In Baturité, Lu. migonei is more abundant in high areas of the hill, although it is also
IP T
collected in the caatinga (Queiroz et al., 1994). The average annual temperature is 25.8C and average annual precipitation is 1,065 mm.
SC R
Niterói is situated at the sea level and has also a tropical climate (Aw type). The natural landscape is mainly composed by Atlantic forest remnants, also with some areas
U
of resting forests and mangroves. The average annual temperature is 23.4C and average
N
annual precipitation is 1,204 mm.
A
In the collection sites, most of the primary vegetation coverage has been replaced by
M
crop plantations, human houses and animal shelters. From October 2015 to February 2016, phlebotomine sand flies were collected using standard CDC light traps, installed
ED
monthly, for four consecutive nights, between dusk and dawn, from 5:00 pm to 6:00 am. Traps were placed at ca. 1 m above the ground in different habitats, including chicken
PT
coops and plantations. Captured sand flies were processed and identified morphologically
CC E
using the taxonomic key proposed by Young and Duncan (1994).
2.2. Morphometric study
A
From each population, 15 males and 15 females identified as Lu. migonei were used
for morphological analysis. The individuals were measured using imaging software integrated with an automated microscope and digital camera (Leica Application Suite; LAS-Leica, Australia). The following structures measured (see Tables 1 and 2): wing length (WL) and width (WW), as well as the lengths of the labrum (L), antennal segment
3 (A3), genital pump plunger (PL), coxite (C) and style (S). Measurements are expressed as mean standard deviation and provided in micrometres.
2.3. Genetic study Genomic DNA was extracted as described elsewhere (Latrofa et al., 2017), using a
IP T
representative number of Lu. migonei specimens (n = 46), according to gender and
sampling area. Partial region of cytochrome c oxidase subunit I gene (cox1, 710 bp) were
SC R
amplified using primers LCO1490 and HCO2198 (Folmer et al., 1994). Each PCR reaction consisted of 4 μl genomic DNA (~100 ng) and 46 μl of PCR mix containing 2.5
U
mM MgCl2, 10 mM Tris-HCl (pH 8.3) and 50 mM KCl, 250 μM of each dNTP, 100 pmol
N
of each primer and 1.25 U of AmpliTaq Gold (Applied Biosystems). The cox1 gene was
A
amplified using the following conditions: 95°C for 10 min, followed by 40 cycles of 95°C
M
for 1 min, 56°C for 1 min and 72°C for 1 min, and a final extension at 72 °C for 7 min. PCR products were examined on 2% agarose gels stained with GelRed (VWR
ED
International PBI, Milano, Italy) and visualized on a GelLogic 100 gel documentation system (Kodak, New York, USA). The amplicons were purified and sequenced, in both
PT
directions using the same primers as for PCR, employing the Taq Dye Deoxy Terminator
CC E
Cycle Sequencing Kit (v.2, Applied Biosystems), in an automated sequencer (ABIPRISM 377). All representative haplotypes of Lu. migonei obtained were deposited in
A
GenBank (accession numbers: MF784908-MF784937).
2.4. Data analyses The differences among the mean of the morphometric measurements in both males and female sand flies were tested by analysis of variance (ANOVA), upon the assumption of normality distribution of the data (assessed by Kolmogorov-Smirnov test). In order to
better understand which morphometric variable would be more effective in predicting category membership (intended here as “population”), morphometric data were assessed by discriminant function analysis, using the relative function available in the software SPSS, version 13.0 for Windows. Sequences of cox1 gene were aligned using ClustalW program (Larkin et al., 2007)
IP T
and compared with those available in GenBank database by BLAST analysis (http://blast.ncbi.nlm.nih.gov/Blast.cgi). Genetic distance (expressed in %) among all
SC R
haplotypes identified, was calculated using the Kimura 2 Parameter substitution model with gamma distributed (G) rates (Kimura, 1980), implemented in the MEGA6 software
(Tamura et al., 2013). The polymorphisms across haplotypes were showed using
U
WebLogo Version 2.8 (Gavin et al., 2004). The phylogenetic relationships were inferred
N
by maximum likelihood (ML) based on general time reversible model (GTR), gamma
A
distributed with invariant sites (G+I), selected by best-fit model (Nei and Kumar, 2000),
M
and tested with 4,000 bootstrap replications, using MEGA6 software (Tamura et al.,
ED
2013). Homologous sequence from Phlebotomus perniciosus and Lutzomyia spp. were

used as outgroups (accession numbers of outgroup sequences are reported in Fig. 2).
CC E
Comparisons of general morphology and morphometric data did not reveal any
remarkable difference among males and females belonging to different populations
A
assessed herein (Tables 1 and 2). However, males and females from Machados and Baturité showed similar length of wings and antennal segment 3 as compared with specimens from Niterói. Average measurements recorded for males and females from each population, along with the statistical data are reported in Tables 3 and 4. For males, the lower and upper
limits of the 95% confidence intervals for wing length, antennal segment 3 and coxite did not overlap with those of the other populations. Therefore, these measurements were useful to discriminate males from Niterói from those from Machados and Baturité (Table 3). For females, wing length appeared to be useful to discriminate Machados from the others as well as length of antennal segment 3 to discriminate Niterói from the others
IP T
(Table 4).
Discriminant analysis showed higher coefficients for the same abovementioned
SC R
measurements, with the addition of wing width for females (Table 5). Indeed, using the
measurements and coefficients derived by discriminant analysis, 80% of the males were classified as belonging to the correct original population. Similarly, 86.7% of the females
N
Niterói and females from Machados (Table 6).
U
were correctly classified, with 100% predicted group membership achieved for male from
A
The BLAST analyses revealed high nucleotide identities (up to 98%) with a sequence
M
of Lu. migonei available in GenBank (accession number: GU909508). Overall, 30 cox1
ED
haplotypes (H1-H30), aligned over 658 sites, were identified, being H1 and H2 the most commonly retrieved (25.6%) (Table 7, Fig. 3). Except for three non-synonymous
PT
nucleotide substitutions (Tyr-Asn in H27; Ile-Val in H10; and Arg-Gln, in H21), all the others were silent mutations. The genetic distance calculated amongst all haplotypes
CC E
identified was up to 3.15%, revealing the existence of two distinct lineages, designated herein as A (north-eastern) and B (south-eastern). The mean nucleotide distance within
A
lineages A and B was 0.75% and 0.6%, respectively (Table 7). All specimens from Baturité and Machados belonged to lineage A, whereas those from Niterói were assigned to lineage B (Table 7). The ML tree grouped all representative haplotypes of each lineage in two monophyletic clades, supported by high bootstrap value (i.e., 99%), with the exclusion of
other Lutzomyia spp. (Fig. 2). Representative cox1 haplotypes here generated herein were deposited in GenBank, under accession numbers MF784908–MF784937.
4. Discussion In the present study, we compared morphologically and genetically three populations
IP T
of Lu. migonei in Brazil. As expected, there was no gross morphological difference between the studied specimens. However, discriminant analysis conducted based on key
SC R
morphometric features (i.e., length of wing, antennal segment 3 and coxite for males, and
length of wing and antennal segment 3 for females) revealed that specimens from Machados and Baturité displayed similar measurements as compared to those of Niterói.

Baturité) presented larger measurements as compared to those of south-eastern Brazil

A
(Niterói). The reasons for these differences are unknown but may be related to
ED
While located over 500 km apart, Machados and Baturité present similar climate and vegetation, even if most of the original vegetation coverage in Machados has been
PT
replaced by crop plantations. In the same way, Machados and Baturité are located 416 and 175 metres above the sea level, whereas Niterói is located at the sea level. Based on
CC E
our results, it may be speculated that the lineages of Lu. migonei identified herein have currently a patchy distribution in Brazil, probably driven by abiotic factors, such as
A
altitude. Of note, the distribution of these lineages is probably not related to climate, as all three study sites present a tropical climate, with similar average annual temperature and precipitation. Genetic analysis based on cox1 sequences was concordant in showing the existence of two well-defined lineages within the populations examined. Indeed, as a corollary of
our morphometric analysis, Lu. migonei specimens of Baturité and Machados formed a distinct genetic group, which was clearly separated from the group formed by eight haplotypes found exclusively in Niterói. This genetic structure may suggest that an abiotic barrier between these populations may have contributed to their segregation, as demonstrated for other sand fly species in Brazil (Esseghir et al., 1997; Arrivillaga et al.,
IP T
2002; Coutinho-Abreu et al., 2008; Souza et al., 2017). Whether these two lineages of Lu. migonei are reproductively isolated remains to be known. Further studies are needed to
SC R
investigate the distribution of these lineages in different Brazilian states. The existence of areas of sympatry should be assessed as well.
The existence of distinct genetic lineages within the same morphospecies has been
U
demonstrated for Lu. longipalpis (Lima Costa et al., 2015) using the period gene (525 pb)
N
and, more recently, for Lu. umbratilis. Souza Freitas et al. (2015, 2016) observed the same
A
results using cytochrome oxidase I (597 bp) and the period clock gene (489 bp) genes,
M
indicating the presence of two distinct clades (North and Northeast populations) under
ED
the name Lu. umbratilis. Whether these lineages represent cryptic species, with different ecological behaviour (e.g., blood feeding pattern; Sales et al., 2015) or even with different
PT
vector competence/capacity for distinct Leishmania spp. remains to be investigated. The hypotheses that Lu. longipalpis would represent a complex of cryptic species
CC E
was raised after the observation of variations in the number of whitish abdominal spots, with either a single pair on the fourth tergite (one spot - 1S) or two pairs, on the third and
A
fourth tergites (two spots - 2S) (Mangabeira, 1969). Years later, Bauzer et al. (2002) provided the first molecular evidence in Brazil for the existence of two sympatric, genetically different populations, corroborating early results of Ward et al. (1983, 1988). These finding were later supported by analysis of male sex pheromones and the
copulatory courtship songs, as well as by microsatellite markers and speciation genes (Vigoder et al., 2010b). In conclusion, our coupled morphometric and genetic analyses indicate the existence of at least two distinct lineages of Lu. migonei in Brazil. Further studies are needed to better understand the role (if any) of these genetically distinct populations in the
IP T
transmission of Leishmania spp. (e.g., L. braziliensis and L. infantum) to animals and
SC R
humans.
