Santschi's (1915c) description of dignata is -
MAJOR. TL 5.5-5.8; head smaller than type, HL 2.4-2.5, HW 2; slightly
more convex on sides. Thorax not so stout; mesonotum with a less raised
ridge. Petiole node impressed, postpetiole with lateral spines longer
and finer. Colour red brown, gaster brown; funiculus and tarsi yellow
brown. Pilosity as type. Head more matt, with puncturate ground
sculpture clear all over (effaced on the face of the type), occipital
reticulation less clearly transverse; base of gaster more strongly
puncturate.
MINOR. TL 2.4; slightly less sculptured than type on dorsum of thorax,
front of head very shiny; propodeal spines longer. Black, appendages
brown or yellow brown.
Specimens from Comba and Mandougo - Santschi has these as "French
Congo" but Wheeler (1922) noted that such locations were not on any
map. Modern gazetteers have a Mandougou in Guinea and Comba in Central
Angola. The collector was A. Weiss, who otherwise made many collections
around Brazzaville, Congo.
In Ivory Coast, from Sudan savannah at
Ferkéssédougou, and also from humid savannah (Lévieux, 1972, 1983a).
Bernard (1952) reported seven minors from N'Zo, Guinea.
He noted it was previously unknown from Guinea being a species of
central Africa but presumably he assumed he was looking at P. sculpturata.
The photomontage of a supposed cotype minor
of welgelegenensis shown (or at least formerly available) on
The Smithsonian Institute website
at http://ripley.si.edu/ent/nmnhtypedb/public/specimeninfopage.cfm?publicconsumption=1&typespecimenID=892
appears to be a normal eastern Africa sculpturata.
The Antweb type images of dignata (below) show that both
major and minor workers are some 25% smaller than the welegelegenensis major and minor
workers. The major clearly has a different shaped head in
full-face view and the minor has much less sculpturation.
