Figs 65–69

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. burundii subsp. nov.; it is, on average, the smallest of the four subspecies, with, relatively speaking, the widest eyes (“ugug” in Fig. 65, Table 17).

Isognathotermes u. ugandensis is also the subspecies that comes from the lowest average altitude ( 625– 1500 m, average = 1015 m); the samples come from Uganda, South Sudan, eastern CAR and Haut-Uele province, DRC). To date, no samples have been sequenced.

Etymology

The name refers to the country ( Uganda) of the type locality.

Material examined

Sixty one old samples from 28 locations. Of the 61 old museum samples examined, 20 were initially labelled as Cubitermes ugandensis , 18 as C. antennalis , five as C. speciosus , and 18 as Cubitermes sp.

Description

Imago

See the description of the imago of I. ugandensis ( Fuller, 1923) with the particularity that the imago of I. u. ugandensis subsp. nov. is clearly the smallest of the four subspecies, with, relatively speaking, the widest eyes, best seen in a PCA (“ugug” in Fig. 65, Table 17), hence the highest IEyD/IHdW ratio (0.25–0.34 vs 0.23–0.28 for the other three subspecies).

Samples previously known as I. antennalis and synonymised with I. ugandensis ( Williams 1966) are here assimilated to the subspecies I. u. ugandensis subsp. nov., because of the proximity of their geographical areas and morphological similarity of their imagines. However, not all individuals of I. antennalis should be considered synonyms of I. u. ugandensis as without molecular data, there is no reason to attribute certain samples to I. ugandensis rather than I. severus . And indeed the ‘unusually’ large size of the “ugxx” ellipse in Fig. 65 ( I. antennalis samples) suggests a high “intrasubspecific” variability, probably linked with genetic heterogeneity.

Chorology-ecology

Isognathotermes ugandensis ugandensis subsp. nov. (including the samples previously identified as I. antennalis ) is the subspecies that comes from the lowest altitude ( 625– 1500 m, average = 1015 m); it was found in Uganda, south-east CAR, South-Sudan, and north-east DRC. Its geographic distribution is linked with the northern Congolian forest-savanna mosaic, the Victoria basin forest-savanna mosaic, and the east Sudanian savanna ecoregions.
