Wasmannia sigmoidea (Mayr)  HNS 

Tetramorium sigmoideum Mayr  HNS  (in Radoszkowsky), 1884: 33. Syntype worker: Cayenne , French Guiana (Jelski) [ NMW]  (examined, one worker here designated LECTOTYPE). Combination in Wasmannia  HNS  and description of queen and male: Forel, 1893: 386.

Comments

Wasmannia sigmoidea  HNS  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 rochai  HNS  . Forel (1884) identified material from St. Vincent Island in the Antilles as W. sigmoidea  HNS  , and described the queen and male. We have not been able to examine the workers of this collection, but the queens match queens of sigmoidea  HNS  from Puerto Rico and Costa Rica.

Kempf (1972) gives the range of sigmoidea  HNS  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  HNS  (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 affinis  HNS  (see under affinis  HNS  ). 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  HNS  is circumcaribbean.

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  HNS  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 (Table 2). It is likely that sigmoidea  HNS  prefers open and synanthropic habitats, hence its undersampling in Costa Rica, where sampling emphasis has been in forested habitats.
