# Ctenocheirodon

Ctenocheirodon pristis is a species of characin native to South America that can grow up to 3.4 cm long (only 3.3 for males). It is the only known member of its genus. Its specific name comes from the Greek word pristis, which means saw. This refers to the projected fins on the underside of the fish.

## Habitat

C. pristis is a freshwater fish and it lives in the drainage basin of the Rio Tocantins in South America. It lives in areas of slow-moving water over river bottoms with little vegetation. As a result of the location, C. pristis lives exclusively in tropical areas.
# Arcevia

Arcevia is a comune in the province of Ancona of the region of Marche, central-eastern Italy. It is one of I Borghi più belli d'Italia ("The most beautiful villages of Italy").

## History

According to tradition, Arcevia originates from a Gallic settlement anterior to the Roman conquest of Italy; following that, it became overshadowed by more important nearby cities, such as Suasa.
Under the name of Rocca Contrada, the town was fortified by Pippin the Younger, King of the Franks, and was then donated by Charlemagne to the Papal States. In the following centuries, Arcevia played a key role in the local balance of power, located as it was at the border of the Marca di Ancona, Umbria, and the Duchy of Urbino. In 1201, Rocca Contrada proclaimed itself a commune independent from Rome, and was indeed recognised as civitas (Latin for "city") by pope Clement IV in 1266, and remained a guelph city ever since.
Known on a local scale for its military might, Rocca Contrada became entwined in the struggles between the numerous conflicts between local powers, until in the 15th century it found itself under siege by Ladislaus, King of Naples, and decided to call upon the help of famous condottiero Braccio da Montone. The latter vanquished the assailants and reconquered the castles around Arcevia they had occupied; for this he was proclaimed Signore of the city. Later on, the troops of Francesco Sforza overtook Rocca Contrada, which, after several vicissitudes, ended up under the rule of the guelph Malatesta family.
After the pacification of the Papal States in the 16th century, Rocca Contrada flourished in the Italian Renaissance: the city witnessed the institution of professorships in classical subjects, the founding of literary academies, and the birth of such significant artists as painter Ercole Ramazzani and architect Andrea Vici in the 18th century.
In 1817, pope Pius VII renamed Rocca Contrada with the current official name of Arcevia. The town passed to the Kingdom of Italy after the unification of the country under the Savoy monarchy. Townspeople fought in the two world wars, and paid for their resistance to Nazi occupation with the slaughter of seventy people on Monte Sant'Angelo (Marche) in May 1944.

## Geography and subdivisions

Arcevia is about 535 metres (1,755 ft) above sea level, on a hill overlooking the valley of the Misa river and the Nevola river, about 50 kilometres (31 mi) south-west from its provincial and regional capital, Ancona.
Arcevia borders the following municipalities: Barbara, Castelleone di Suasa, Genga, Mergo, Montecarotto, Pergola, Rosora, San Lorenzo in Campo, Sassoferrato, Serra de' Conti, and Serra San Quirico.

# Culex nigripalpus

Culex nigripalpus (Florida SLE mosquito) is a species of medium-sized, dark, blood-feeding mosquito of the family Culicidae.

## Distribution

Culex nigripalpus has been found to occur in the following countries: Anguilla, Bahamas, Barbados, Belize, Brazil, Colombia, Costa Rica, Cuba, Dominica, Dominican Republic, Ecuador, El Salvador, French Guiana, Grenada, Guadeloupe, Guatemala, Guyana, Haiti, Honduras, Jamaica, Martinique, Mexico, Montserrat, Nicaragua, Panama, Paraguay, Peru, Puerto Rico, Saint Lucia, Saint Vincent and the Grenadines, Suriname, Trinidad and Tobago, United States, Venezuela, Virgin Islands. In the United States, it is found from Texas to North Carolina in warm, humid coastal habitats and in the Mississippi River basin as far north as Kentucky.

## Ecology

Culex nigripalpus larvae live in fresh water in semi-permanent or permanent marshes, ditches, retention ponds, and grassy pools, and females prefer to lay eggs in freshly flooded ditches.

## Medical significance

Culex nigripalpus is a principal disease vector in Florida – the primary enzootic vector to wild birds and the primary epidemic vector to humans of the Saint Louis encephalitis (SLE) virus. It has been experimentally demonstrated to be capable of transmitting West Nile virus (WNV). Its habit of feeding on both birds and humans gives it significant potential for transmission of zoonotic infections from birds to humans. It is also a vector of transmission of Eastern equine encephalitis (EEE), dog heartworm, and Avian malaria.

Writing for AllMusic, reviewer Scott Yanow stated: "the colorful ensembles and the very adept soloing by the French horns make this a particularly memorable recording. Strange that this album has been obscure for so long. Only the brief playing time keeps this intriguing set from getting a higher rating".

# Argelander (crater)

Argelander is a lunar impact crater that is located in the south-central highlands of the Moon. It was named after the German astronomer Friedrich Argelander. It lies in the midpoint between the smaller crater Vogel in the north and the larger Airy to the south. To the northwest is the worn remnant of Parrot. Just to the west is a shallow cleft in the surface that follows a course to the north-northwest, intersecting the southeast rim of Parrot.
The rim of Argelander is somewhat worn and indented, although less distorted than Airy to the south. The bottom is relatively flat and there is a small central rise. There is a curved depression in the surface following the western rim, giving the wall a rampart on that side.

## Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Argelander.
