The Subgenus Dendromyia Theobald: A Review with Redescriptions of Four Species (Diptera: Culicidae)

Motta and Lourenço-de-Oliveira (1995) redescribed the type species of Dendromyia, Wy. luteoventralis Theobald, and considered only other five species as having morphological, biological and biochemical (Motta et al. 1998) similarities suggestive of a monophyletic group: Wy. luteoventralis Theobald, Wy. ypsipola Dyar, Wy. jocosa (Dyar & Knab), Wy. testei Senevet & Abonnenc, Wy. trifurcata Clastrier and Wy. complosa (Dyar). The many unrelated Wyeomyia species previously included in the subgenus Dendromyia (Lane & Cerqueira 1942, Lane 1953, Judd 1996) were excluded from the subgenus. The present paper is part of a series involving the characterization of species and subgenera ofWyeomyia (Motta and Lourenço-de-Oliveira 1995, Motta et al. 1998, Lourenço-de-Oliveira et al. 1999). In this paper, four species belonging to subgenus Dendromyia, Wy. ypsipola, Wy. jocosa, Wy. testei and Wy. complosa, are redescribed in all life stages for a better interpretation and application of the subgeneric name.

MATERIALS AND METHODS

The material examined during this study came from collections made at different localities in Brazil and Peru. This material is deposited at Instituto Oswaldo Cruz (IOC), Rio de Janeiro. Other material examined was from the entomological collections of the Faculdade de Saude Pública, São Paulo (FSP-USP) and the United State National Museum (USNM), Smithisonian Institution, Washington, DC. For the geographic distribution of each species, the findings of other workers and those recorded by Knight and Stone (1977) and Knight (1978) were also included. Illustrations and keys for the identification of the species of Dendromyia were based on direct observation of morphological characters, except for Wy. trifurcata, for whose morphological characters were taken from the original description and the illustrations given by Clastrier (1973). The holotype and the other specimens of Wy. trifurcata, recorded as being in the collection of the author (Knigth & Stone 1977) and possibly transferred to the Museé National d'Histoire Naturelle, Paris, were not available for this study.

Except for letter designations applied to the lobes of gonostylus (Belkin et al. 1970), the morphological terminology follows Harbach and Knight (1980). An asteristik (*) following the abreviations of life stages or sex indicates that at least some portion of these were figured in the cited paper. The illustrations are based on specimens deposited in IOC and USNM.

Bionomics: Wy. ypsipola has been collected on human bait in the forest during the day-time. Immature stages were found in the axils of Heliconia sp., Calathea sp. and Aracea. Like Wy. luteoventralis, and the others species ofDendromyia,the larvae of Wy. ypsipola have agressive behavior, killing but not eating prey.

Distribution: Wy. ypsipola is known from Panama, Guyana, Colombia, Peru (Iquitos), Bolivia, Brazil, Trinidad and Surinam.

Systematics: Wy. ypsipola is undoubtedly most closely related specie to Wy. luteoventralis, because the immature stages are very similar. Wy. ypsipola is easily distinguished from Wy. luteoventralis as well as from the otherDendromyia species in the external characters of the adults and male genitalia. In the female, it is distinguishable fromWy. luteoventralis, Wy. trifurcata and Wy. testei by having midtarsomeres II-V white-scaled on one side; differs fromWy. jocosa and Wy. complosa in having the clypeus bare. In the male genitalia, Wy. ypsipola differs from the otherDendromyia species in having the gonostylus with a tuft of long setae apically and the lobes of tergum IX roughly triangular with 8-11 long setae on each. In the pupa Wy. ypsipola differs from Wy. trifurcata, Wy. testei, Wy. jocosa andWy. complosa in having the paddle strongly narrowed from the middle to the apex; it is similar to Wy. luteoventralisexcept for slight variations in setal branches of the following setae: 7-V usually with 3 (1-4) branches; 11-VII usually with 3 (2-4) branches and 9-VIII with 24-30 branches. The paddle index is 3.5-4.7 (mean 4.3). In larva Wy. ypsipola differs from Wy. trifurcata in having seta 15-C short, about 1/7 the length of 14-C; from Wy. complosa in having seta 2a-S strong and heavily sclerotized; from Wy. testei in having seta 6-P with at maximum of 3 branches; from Wy. jocosa in having the laciniarastrum with 7 teeth; it is similar to Wy. luteoventralis, except for some diferences: the laciniarastrum(LR2) has numerous setae distributed in several rows, the maxillary pilose area extends to the base of the maxilla and the maxillary palpus has 4 teeth (as figured by Harbach and Peyton 1993 and Motta and Lourenço-de-Oliveira 1995). In Belém, two forms of Wy. ypsipola were found: the typical form that occurs in Panama and all localities searched in Brazil, and another restricted to Belém. The Belém form is distinguished from the typical form only in the male genitalia by the presence of a capitate process bearing a row of setae at the dorso-apical margin of the gonocoxite (Fig. 3-G); aedeagus with the apical tergal arms joined and moderately pointed apically, and the median sternal plate membranous with lozenge-shaped rugose area (Fig. 3-F); and the posterior margin of tergum VIII with a lateral lobe bearing setae (Fig. 4-D). No diferences in the morphological characters of the females, larvae and pupae of the two forms were observed. A decision as to the taxonomic status of the Belém form cannot be made without careful reexamination of morphological characters of all available material in museuns, study of additional imature specimens and a complementary biochemical or molecular analysis.

Distribution: known from Panama, Venezuela, Mexico and Colombia.

Bionomics: we did not find immature stages or adults of Wy. jocosa in the localities where we collected the other species of Dendromyia in Brazil and Peru. Heinemam and Belkin (1978a), in Panama, collected larvae of Wy. jocosa in Aracea (Montrichardia sp. and Dieffenbachia sp.), as well as in axils and bracts of Heliconia sp. and Calathea sp. There are no available data on the biting habits of Wy. jocosa.

Systematics: Wy. jocosa is more closely related to Wy. luteoventralis and Wy. ypsipola than to the other species ofDendromyia, mainly based on similarities in the immature stages. In the female, Wy. jocosa differs from Wy. luteoventralis, Wy. ypsipola, Wy. testei and Wy. trifurcata by having scales on the clypeus and from Wy. complosa in having the midtarsomeres dark. In the male genitalia, Wy. jocosa differs from Wy. ypsipola in having the gonocoxite without an apical tuft of long setae; from Wy. complosa and Wy. trifurcata in having tergum VIII without an apicolateral tuft of long, strong setae; from Wy. testei and Wy. luteoventralis in having tergum IX with broad, foliform setae with pointed apices. In the pupa, Wy. jocosa differs from Wy. luteoventralis and Wy. ypsipola in having the paddle gradually narrowed toward the apex; from Wy. trifurcata in having seta 1-I branched at different levels; from Wy. complosa in having seta 6-III anterior to seta 4-III and seta 5-CT usually with more than 3 branches; it differs from Wy. testei in having seta 3-II very long, almost the same length as the next abdominal segment, and seta 3-III lateral to seta 1-II. In the larva, Wy. jocosa differs from Wy. trifurcata in having seta 15-C short, about 0.14 the length of 14-C; from Wy. complosa in having seta 2a-S strong and seta 6-P with 2 or 3 branches; and from Wy. luteoventralis and Wy. ypsipola in having seta 4-VIII usually with 2 branches and the maxilla with 4 teeth on LR.

Motta and O. V. Silva coll., M.A. Motta det., from eggs laid at the laboratory by wild-caught females on human bait, 1 male Le Pe G, 1 female Le Pe G, 2 female Le Pe (IOC).

Bionomics: females of Wy. testei have been collected on human bait in forest during the daytime. Immature stages were found only in the axils of bromeliads (Ananas sativus). The larvae have agressive behavior, killing but not eating prey. Numerous immature stages were collected by us breeding together with Wy. aphobema Dyar and Wy. melanocephalaDyar & Knab.

Distribution: French Guyana, Guyana and Brazil.

Systematics: Wy. testei seems to be closely related to Wy. trifurcata, based mainly on morphological characters of the male genitalia (the shape of the gonostylus, and tergum IX with short, slender setae). Also, the immature stages of both species inhabit bromeliads (genus Ananas), while the other species of Dendromyia have been collected in plants of order Zingiberales, such as Heliconia, Calathea, and Aracea. In the female, Wy. testei differs from Wy. jocosa and Wy. complosa in the absence of scales on the clypeus; from Wy. luteoventralis and Wy. trifurcata in having the midtarsomeres with white scales; from Wy. ypsipola in having midtarsomeres I, II and occasionally the base of III covered with white scales; IV and V dark. In the male genitalia, Wy. testei differs from Wy. ypsipola in having the gonocoxite without an apical tuft of setae; from Wy. trifurcata and Wy. complosa in having tergum VIII without apicolateral tufts of long setae; from Wy. luteoventralis and Wy. jocosa in having tergum IX with small hair-like setae. In the pupa, Wy. testei differs from Wy. luteoventralis and Wy. ypsipola in having the paddle gradually narrowed to the apex; from Wy. trifurcata in having seta 1-I branched at different levels; from Wy. complosa in having seta 6-III anterior to seta 4-III and seta 5-CT usually with 3 (4, 5) branches; Wy. testei differs from Wy. jocosa in having seta 3-II nearly as long as half of the length of the next abdominal tergum. In the larva, Wy. testei differs from Wy. trifurcata in having seta 15-C short, about 1/7 the length of 14-C; from Wy. complosa in having the siphon with acessory seta 2a-S strong and heavily pigmented; from Wy. jocosa, Wy. luteoventralis and Wy. ypsipola in having seta 6-P with 11-18 branches and seta 5-P usually with 9 (7-10) branches.
