Crematogaster (Sphaerocrema) longiceps Santschi

Type location Mali (Soudan français) (Cremastogaster longiceps, n. sp. (in litt.), Santschi, 1910c: 376, queen); queen only described (see Bolton, 1995, where type location is wrongly given as "Sudan") .

Santschi (1910c) under a note reporting Cr. wellmanni from Congo (as Cremastogaster (subgen. Atopogynes?) Welmani For.), stated (my translation) -

"I conjecture that the queen described under the name of Crematogaster concava belongs to this species. I received it from Brazzaville (Weiss). Libreville (Paris Museum).
In Soudan français [Mali] is found a species very close with the queen differing in having a much longer head, C. longiceps, n.sp. (in litt) (Paris Museum)".

Santschi (1916b: 500) wrote, however, wrote confusingly "the queen that M. Forel attributed with doubt to C. Welmani appears to belong to another species.  The true queen of C. Welmani is probably that described by Emery as C. concava or a very close species that Forel named as C. luciae. I have supposed the synonymy of C. Welmani with C. concava Em. queen (not his 1899 queen).  Then C. Luciae For. = C. Welmani For. var. luciae For.".
