The photomontage of
a syntype worker is collated from http://www.antweb.org/specimen.do?name=casent0902353
(1911f) has itinerans as (my translation) - "Very similar to
the variety richteri Forel, but entirely brown; the head a
little narrower, the nodes also narrower and the pilosity slightly less
abundant. Kigerama, East Africa, between the great lakes (Breslau
Museum). This American species has evidently been imported into Africa
with some plants, if it is not an error made at the Museum". Santschi
(1914d: 355) simply reported Solenopsis pylades For. v. itinerans
For. as "Guinée française: Conakry 4 workers". Without sighting the
specimens, I feel these identifications could easily have been wrong.
Creighton (1930b) gave a description and illustrations,
this is at and . .
richteri from Argentina was raised to species by Buren (1972: 4) in
his attempt to clarify the status of genus members regarded as imported
into the USA. The "S. richteri" as it was known in the USA he
redesignated as Solenopsis invicta n.sp. In very simple terms, S.
richteri majors have a very distinctive large bright spot on an
otherwise nearly black gaster; the rest of the body piceous brown. In
general S. invicta appears to be somewaht lighter in appearance.
The general colouration of S. saevissima Buren
gave as largely pale to darker yellow, with smaller workers often
duller; the frons is distinctively yellowish with the mandibles and
often the antennae dark brown.
A comprehensive illustrated description was provided by
Trager (1991: 188), this is at and .
