Specimen Labels

Longino & Fernández (2007) - The few Costa Rican records are as follows. David Olson collected workers during his study of Winkler and pitfall trap sampling methods at La Selva Biological Station (Olson 1991, as Wasmannia sp. 1). This was the only known collection from La Selva, in spite of intensive inventory effort there (Longino et al., 2002), until an August, 2004 collection of workers and alate queens from the rootball of a palm tree in the laboratory clearing. Workers occurred in four different samples from the Project ALAS expeditions to the 500 m site on the Barva Transect: two Malaise trap samples, one flight-intercept sample, and one sweep net sample. It is likely that sigmoidea prefers open and synanthropic habitats, hence its undersampling in Costa Rica, where sampling emphasis has been in forested habitats.

Identification

Wasmannia sigmoidea is the second oldest name in the genus and to date has been poorly characterized. It has never been satisfactorily differentiated from other species in the genus, particularly Wasmannia rochai. (Longino & Fernández 2007)

Keys including this Species

Distribution

Longino & Fernández (2007) - Kempf (1972) gives the range of sigmoidea as Guianas, Antilles St. Vincent, Grenada, and Santa Catarina state of Brazil. The Guianas are listed because of the type locality in French Guiana and some Surinam specimens he tentatively identified as sigmoidea (Kempf 1961). The St. Vincent record is based on Forel’s publication. We do not know the basis of the Grenada record. The Santa Catarina record is based on a published record by Mayr (1887), which is a misidentification of specimens of Wasmannia affinis. We have examined abundant material from Puerto Rico, multiple collections from Costa Rica, and a collection from Guarico state in Venezuela. Thus the current known range of sigmoidea is circumcaribbean.

Distribution based on Regional Taxon Lists
