“…The authors were able to discriminate these three species with 100% accuracy using the canonical variate analysis. In turn, Dujardin & Le Pont (1999) evaluated some sub-species of the genus Psychodopygus, demonstrating that they were able to separate the species Ps. carrerai thula Young, 1979 from Ps.…”

Comparative study of the phlebotomine sand fly species (Diptera: Psychodidae: Phlebotominae) of the genera Nyssomyia Barretto, 1962, Bichromomyia Artemiev, 1991, and Migonemyia Galati, 1995, vectors of American cutaneous leishmaniasis in Brazil

Phlebotominae, a group of insects with great medical importance especially in Brazil, are responsible for transmitting causal agents of cutaneous and visceral leishmaniasis. In Brazil, the most important species of Leishmania Ross, 1903 are L. (Viannia) braziliensis Vianna, 1911, whose main vectors are Nyssomyia intermedia Lutz & Neiva, 1912, Ny. neivai Pinto, 1926, Ny. whitmani Antunes & Coutinho, 1939 and Migonemyia migonei França, 1920 and L. (Leishmania) amazonensis Lainson & Shaw, 1972, for which Bichromomyia flaviscutellata Mangabeira, 1942 is the main vector. The present study sought to investigate the morphological as well as geometrical and linear morphometric characteristics of these five sand flies in an attempt to cluster these species. Our aim was to reveal some of the characters that might help identify these phlebotomine species and also be useful in future phylogenetic studies. Comparative analyses by linear and geometric morphometric characters allowed us to distinguish the genera of these sand flies and assess the taxonomic position of Ny. intermedia and Ny. neivai, the so-called "cryptic species". Significant differences were observed in several of the analyzed structures, including the centroid size of the wings and the ratio between the ejaculatory filament and its tip. Based on the linear morphometric analytical results, the size of the centroids of the wings and their shapes indicated that these three species of Nyssomyia are phenetically more similar to Mg. migonei (all vectors of L. (V.) braziliensis) than to Bi. flaviscutellata (vector of L. (L.) amazonensis). These results are in agreement with the division of the genera Nyssomyia and Bichromomyia.

“…In the same manner, combining morphological and molecular character information can result in complementary analyses that can produce a more robust systematics study. The two-pronged molecular and morphological approach maximizes the information available to answer questions pertaining to systematics, each "prong" serving as a "proof" of the other method when concordance is reached (Baker et al 1998, Dujardin et al 1999a, Azevedo et al 2000, Torgerson et al 2003, Malhotra and Thorpe 2004, Paquin and Hedin 2004, Knaden et al 2005.…”

Morphometric and Molecular Analyses of the Sand Fly Species Lutzomyia shannoni (Diptera: Psychodidae: Phlebotominae) Collected From Seven Different Geographical Areas in the Southeastern United States

et al. 2011

A morphometric and molecular study of adult male and female Lutzomyia shannoni (Dyar 1929) collected at seven different locations within the southeastern United States was conducted to assess the degree of divergence between the grouped specimens from each location. The collection locations were as follows: Fort Bragg, NC; Fort Campbell, KY; Fort Rucker, AL; Ossabaw Island, GA; Patuxent National Wildlife Research Refuge, MD; Suwannee National Wildlife Refuge, FL; and Baton Rouge, LA. Forty males and forty females from each location were analyzed morphometrically from 54 and 49 character measurements, respectively. In addition, the molecular markers consisting of the partial cytochrome c oxidase subunit I (from 105 sand flies: 15 specimens/collection site) and the partial internal transcribed spacer 2 (from 42 sand flies: six specimens/collection site) were compared. Multivariate analyses indicate that the low degree of variation between the grouped specimens from each collection site prevents the separation of any collection site into an entity that could be interpreted as a distinct population. The molecular analyses were in concordance with the morphometric study as no collection location grouped into a separate population based on the two partial markers. The grouped specimens from each collection site appear to be within the normal variance of the species, indicating a single population in the southeast United States. It is recommended that additional character analyses of L. shannoni based on more molecular markers, behavioral, ecological, and physiological characteristics, be conducted before ruling out the possibility of populations or a cryptic species complex within the southeastern United States.

“…Las medidas realizadas fueron tratadas a ſn de eliminar el efecto del tamaño isométrico y trabajar con variables de conformación, para esto, todas las variables medidas se normalizaron por el logaritmo en base 10 y fueron promediados a ſn de obtener un estimador de tamaño (ET) para cada individuo independientemente del grupo taxonómico, éste se obtuvo del promedio de todas las variables mediadas por individuo. La diferencia entre el ET y el valor de la variable por cada individuo fue utilizada para construir una nueva matriz de datos libres de tamaño isométrico (Arrivillaga et al, 1999;Dujardin et al, 1999;Dujardin & Le pont, 2000).…”

Morphometric analysis of four sympatric species of the genus Anacroneuria (Plecoptera: Perlidae)Four sympatric species of stoneƀies were evaluated (A. chorrera, A. tachira, A. cacute, and A. paleta) with morphometric analysis to estimate their differentiation through changes in shape. Results indicated no signiſcant variance in form, showing morphological homogeneity explained by phenotypic integration resulting from the ecological similarity. Additional studies with non-traditional tools may help to delimit these species.
