Figs 65–66, 69

Diagnosis

Soldiers and workers do not allow this subspecies to be distinguished from the other three.

The imago is close to that of I. u. kenyae subsp. nov. (but their geographical distributions are disjunct); it is, on average, the second largest of the four subspecies, best seen in a PCA (“ugma”, Fig. 65); it is the subspecies with the greatest distance between the apical and the first marginal teeth (IMlAmD = 0.23–0.27 mm vs 0.20–0.25 mm for all three other subspecies, Table 17). It comes from a relatively high altitude (1460–1770 m, average = 1560 m), from Malawi and northern Zambia.

Etymology

The name malawii (from Malawi) refers to the country of the type locality.

Material examined

Eleven samples from eight locations; all old museum samples initially identified either as Cubitermes minitabundus (six samples) or C. ugandensis (five samples).

Description

Imago

See the description of the imago of Isognathotermes ugandensis (Fuller, 1923) with the particularity that the imago of I. u. malawii subsp. nov. is the second largest of the four subspecies, best seen in a PCA (“ugma” in Fig. 65, Table 17). This is the subspecies with the greatest distance between the apical and the first marginal teeth (IMlAmD = 0.23–0.27 mm vs 0.20–0.25 mm for all three other subspecies, Table 17).

Soldier

See the description of the soldier of Isognathotermes ugandensis (Fuller, 1923) .

Worker

See the description of the worker of Isognathotermes ugandensis (Fuller, 1923) .

Chorology-ecology

Isognathotermes ugandensis malawii subsp. nov. was found between altitudes of 1460 and 1770 m (average = 1560 m), in the central Zambezian miombo woodlands in Malawi and northern Zambia.
