LIMONIINAE 
LIMONIINI 
Limonia (Limonia) vilhelmi Alexander 
1924. Limonia vilhelmi Alexander; Arkiv for Zoologi, 16, no. 18 : 2-3. 
The unique type, a female, was from Birunga, Mt. Mikeno, altitude 3,100 
meters, March 21, 1921, collected by Gyldenstolpe. A male specimen in the 
present series is from near the type-locality, Rueru Camp, on the southwest slope 
of Mt. Mikeno, altitude 9,150 feet, in bamboo region, March 15, 1927 (J. Be- 
quaert). 
A question of synonymy in the naming of these large mountain species of 
Limonia has arisen. In my opinion, Dr. Speiser, when describing L. rhanthisa 
(Wien. Ent. Zeitung, 40:87-88; 1923) has inadvertently created a synonym 
of his L. rhizosema (Sj6stedt’s Kilimandjaro-Meru Exped., Diptera, Orthorapha 
Nematocera: 48—49, figs. 6-7; 1909). The original description of the latter calls 
only for a species with the tips of the femora blackened, no mention being made 
of any specimens in the type-series having a narrower subterminal dark ring. 
Later, in a letter to Edwards (Trans. Linn. Soc. London, Zool., (2) 15:201; 
1912), Speiser mentioned one specimen in this series as having a subtermi- 
nal ring, the remainder of the series having this terminal in position. When 
describing rhanthisa, Speiser restricted the name to the species with an apical 
dark ring rather than applying it to the form not defined in the original diagnosis 
of rhizosema. The lectotype specimen of rhizosema in the Riksmuseum in Stock- 
holm has the dark femoral tips, making rhanthisa a strict synonym. The material 
in the type-series of this species (from Kilimanjaro, May to August, 1905, 
collected by Sjostedt) with a subterminal dark femoral ring may pertain to 
Limonia subapicalis, new name (for L. capensis Alexander, Ann. So. Afr. Mus., 
17 : 143-145, pl. 10, fig. 6; 1917, described in Lzbnotes; preoccupied by L. 
capensis Macquart, 1838), to L. vilhelmi Alexander, as discussed above, or may 
represent still another of these showy mountain forms of Limonia.
