Dorylus (Typhlopone) obscurior Wheeler - new status

{link to the Hymenoptera Name Server} Type location Guinea (Dorylus (Typhlopone) fulvus Westwood var. obscurior Santschi, Wheeler, 1925b: 1; but use of Dorylus (Typhlopone) fulvus Westw., St. badius Gerst. v. obscurior n. var., Santschi, 1914d: 333; major & minor workers) collected at Conakry by F. Silvestri.


Santschi's (1914d) description of obscurior is at {original description}.

WORKERS - TL (variety obscurior) 5 to 13 mm; head, thorax, petiole and legs rich chestnut brown, gaster brownish yellow, mandibles and antennae near black; smallest morphs more uniformly brownish yellow (Wheeler, 1922: 349) see {original description}. Note - Wheeler (1925b) recorded only "two males from Ruanda", collected by Y. Sjostedt and W. Leche.


{Dorylus (Typhlopone) obscurior} Wheeler (1922) included drawings of the major worker, in dorsal view of the full insect (right), and details of the male, of the subspecies badius variety obscurior. The specimens were collected from the floor of a hut, where they came up out of a hole in the floor.

The evidence from the old and modern findings is that this is a forest species.


{Dorylus obscurior worker} The photomontage of the type worker is collated from http://www.antweb.org/specimen.do?name=casent0911361.


{Dorylus obscurior male head}Chocolate brown, darker than badius, eurous or typical North African " fulvus"; head blackish, gaster a little paler than alitrunk and petiole; wing membranes also a little duller and deeper tint; hairs and pubescence less golden and shining, more grayish; TL 33-36 mm, PW < 6 mm.

{Dorylus obscurior male} The photomontage of matching male from Kenya is collated from http://www.antweb.org/specimen.do?name=casent0217149&shot=p1&project=null. There it is listed as Dorylus fulvus, although the morphology and appearance matches the worker above, it is much smaller (assuming the scales to be correct) but it certainly is not a specimen of D. fulvus.
