Culex nigripalpus Distribution Expansion: First Record in Virginia, New County Records in North Carolina, and Revised United States Map.

Theobald first described Culex nigripalpus in 1901 from St. Lucia Island of the Lesser Antilles. It is a Neotropical mosquito species that is documented throughout Central and South America, the Caribbean, and the southeastern USA.

Mosquitoes (Diptera: Culicidae) of Singapore: Updated Checklist and New Records.

Prior to 1965, Singapore was part of the Malaya (now Malaysia) and was usually not mentioned when mosquito records were reported for Malaya. Consequently, many species that occurred in Singapore were not listed in the world mosquito catalog, and the available checklist for Singapore since 1986 is incomplete, with some imprecise species information. In updating this checklist, we examined and verified mosquito specimens collected from Singapore in various depositories, including a thorough review of past taxonomic literature.

New County Records Demonstrating a Northern Expansion of in South Carolina, USA.

, a new species of the Gigas Complex of subgenus (Diptera: Culicidae) in Thailand, contrasted with known forms of the complex.

Anopheles (Anopheles) prachongae, a new species of the Gigas Complex from northern Thailand, is described and illustrated in the adult, pupal and larval stages, and bionomics and chaetotaxy tables are provided for the immature stages. The species is distinguished from Anopheles baileyi, the only other species of the complex known to occur in Thailand, and contrasted with other taxa of the complex that occur in the Oriental Region. Available morphological data indicate that An.

A chronological list of species based on date of publication is provided for confirmed mosquito species in West Virginia. Five additional newly found species in the state are documented with collection data. Two previously misidentified or mislabeled published records are corrected.

Mansonia titillans: New Resident Species or Infrequent Visitor in Chatham County, Georgia, and Beaufort County, South Carolina, USA.

In September, October, and November 2014, adult Mansonia titillans were collected at 4 separate sites near Savannah in Chatham County, Georgia, and 1 site in Muscogee County, GA, during routine mosquito surveillance. Although previously recorded from Beaufort County, SC, and several inland southern Georgia counties, recent reports of this species from coastal Georgia or South Carolina are lacking. These newly captured Ma.

Aedes pertinax, a Newly Recognized Mosquito Species in the United States.

Specimens of a mosquito new to the continental USA, Aedes pertinax, were retrospectively identified from 2 collections made in 2011 in Indian River County, FL. Routine mosquito surveillance in subsequent years yielded more than 700 specimens appearing in 100 collections. The distribution of this mosquito in Florida and the United States is currently unknown, and recognition of the adult female is likely hampered by morphological similarities to Ae.

First Record of Aedes stimulans from Louisiana.

The first confirmed collection of Aedes stimulans in Louisiana was made in St. Tammany Parish, LA. A single adult female was collected by a large-bore aspirator in March 2011, and identified by microscopic and molecular methods.

Morphology of the larvae, male genitalia and DNA sequences of Anopheles (Kerteszia) pholidotus (Diptera: Culicidae) from Colombia.

Since 1984, Anopheles (Kerteszia) lepidotus has been considered a mosquito species that is involved in the transmission of malaria in Colombia, after having been incriminated as such with epidemiological evidence from a malaria outbreak in Cunday-Villarrica, Tolima. Subsequent morphological analyses of females captured in the same place and at the time of the outbreak showed that the species responsible for the transmission was not An. lepidotus, but rather Anopheles pholidotus.

Differentiation of Aedes atlanticus and Aedes tormentor by restriction fragment length polymorphisms of the second internal transcribed spacer.

Using novel DNA sequence data, we designed a restriction enzyme assay that distinguishes Aedes atlanticus and Ae. tormentor, based on size polymorphisms. The restriction endonuclease Hpy188I digests polymerase chain reaction-amplified 2nd internal transcribed spacer products once for Ae.

Sequence, secondary structure, and phylogenetic analyses of the ribosomal internal transcribed spacer 2 (ITS2) in members of the North American Signifera Group of Orthopodomyia (Diptera: Culicidae).

Mosquitoes of the genus Orthopodomyia (Diptera: Culicidae) are little known and of uncertain epidemiological importance. In the United States, there are three Orthopodomyia species (i.e.

() (Diptera: Culicidae), not the malaria vector we thought it was: Revised male and female morphology; larva, pupa, and male genitalia characters; and molecular verification.

The name Zavortink, commonly used for an important malaria vector in the eastern cordillera of the Andes, is here corrected to Zavortink. We discovered that specimens from Peru, and reared-associated specimens from Ecuador, had unambiguous habitus characters that matched those on the male holotype of However, the specimens do not exhibit characters of the female allotype and female paratypes of , which are actually . Our specimens are the first correctly associated females of , which allow us to provide a new morphological interpretation for the adult habitus of this species.

Illustrated keys to the mosquitoes of Thailand. VI. Tribe Aedini.

Illustrated keys for the identification of the fourth-instar larvae and adult females of the mosquito species of tribe Aedini in Thailand are presented, along with the geographic distribution of the species and the known habitats of their immature stages. The keys are the first to encompass the recent revisionary studies of tribe Aedini. One hundred and seventy-five species of Aedini belonging to 38 genera and 18 subgenera are recognized in Thailand.

Recent discovery of widespread Ixodes affinis (Acari: Ixodidae) distribution in North Carolina with implications for Lyme disease studies.

Ixodes affinis, which is similar morphologically to Ixodes scapularis, is widely distributed in North Carolina. Collections have documented this species in 32 of 41 coastal plain counties, but no piedmont or mountain counties. This coastal plain distribution is similar to its distribution in Georgia and South Carolina, where it is considered an enzootic vector of Borrelia burgdorferi sensu stricto.

An annotated list of the mosquitoes (Diptera: Culicidae) of Mississippi.

There has been no previous systematic statewide study of mosquitoes in Mississippi. This survey, resulting in the collection of over 400,000 specimens, was conducted by the authors from 2003 to 2007 throughout much of the state using CO2-baited CDC light traps and larval dipping. In addition, a health department contract mosquito surveillance technician collected several thousand specimens from the state from 2001 to 2003.

Rapid assessment of mosquitoes and arbovirus activity after floods in southeastern Kansas, 2007.

A rapid assessment was conducted in July-August 2007 to determine the impact of heavy rains and early summer floods on the mosquitoes and arbovirus activity in 4 southeastern Kansas counties. During 10 days and nights of collections using different types and styles of mosquito traps, a total of 10,512 adult female mosquitoes representing 29 species were collected, including a new species record for Kansas (Psorophora mathesoni). High numbers of Aedes albopictus were collected.

New diagnostic characters for females of Psorophora (Janthinosoma) species in the United States, with notes on Psorophora mexicana (Bellardi) (Diptera: Culicidae).

Anopheles lindesayi japonicus Yamada (Diptera: Culicidae) in Korea: comprehensive review, new collection records, and description of larval habitats.

Anopheles lindesayi japonicus Yamada is an uncommonly collected mosquito in Korea, and its presence is based upon limited collection data and anecdotal reports in Korean mosquito literature: 45 specimens collected from 15 identified sites. This study reports the collection of 538 specimens from 16 sites as part of the authors' 2004-2007 anopheline surveillance. Larvae were collected from stream margins, stream pools, rock pools, seepage springs, artificial containers, swamps, and ditches and were found in association with seven other culicid species.
