Oldroyd, 1970
, by original designation.
Oldroyd (1970: 269)
has provided a good description of
Dogonia
(the name being derived from the locality Mt Ndogo). The genus is easily identified using the key published by Londt (1994), which was partly updated by
Dikow and Londt (2000)
.
Dogonia
is easily separated from most of the other Afrotropical
Stenopogoninae
by its possession of setose anatergites, a character found in only eight of 41 described genera. In addition,
Dogonia
has a well-developed antennal style (which clearly separates it from
Microstylum
and
Daspletis
) leaving it in a small group of six genera that possess setose anatergites and a well-developed antennal style.
Dogonia
appears most similar to
Dioctobroma
as only these two genera have slender occipital setae (others have obvious macrosetae as well as fine setae). These two genera can be separated from each other using various features such as antennal form (i.e. scape and pedicel almost equal in length in
Dogonia
; scape clearly longer than pedicel in
Dioctobroma
), and male terminalia form (e.g. hypandrium is about as long as epandrial lobes in
Dogonia
; hypandrium is less than half the length of epandrial lobes in
Dioctobroma
).
