These oldest known mounds were built--presumably, if it was the same species--by Macrotermes falciger
, a close relative of bellicosus, in Upper Katanga in the Democratic Republic of Congo.
In the order Isoptera, the following species are the most consumed Macrotermes falciger, Macrotermes natalensis and Macrotermes subhyalinus in the adult stage.
falciger, the percentages are 83% and 11%, respectively.
Notopodial falcigers are homogomph with a short unidentate falciger with 2 or 3 inconspicuous fine teeth.
The neurosetae consist of an upper group of spinigers, a middle group of thin falcigers, and a lower group of short, stout falcigers, which is unlike the neurosetae described for B.
roussaei, despite the fact that the latter has priority but he was following von Marenzeller (1888:7); further, by comparing Mediterranean and Vietnamese specimens, he indicated (1898:261-262) that the main differences were the relative size of the compound falciger blade, the relative length of antennae, peristomial and dorsal cirri, the first chaetiger with branchiae, and the presence of the whitish segment.
At the same time, we might have to reconsider the early proposal by Pruvot & Racovitza (1895:422) about the specific characters such as pigmentation pattern, length of antennae, their relative articulation, start of branchiae and their maximal filament number (size-dependent), type of pectinate chaetae, blade relative size features in compound falcigers, form and shape of the subacicular hooks, number of abranchiate posterior chaetigers, and number and length of anal cirri.
Median neurosetae are paleae with blade serrate and one homogomph spiniger with short blade and one heterogomph falciger with a ventrally projected distal tooth, fused to the blade.
Nereis Linnaeus is set apart from other nereidids because it has conical paragnaths in both pharyngeal rings and homogomph falcigers in posterior setigers (Wu et al.
Compound chaetae, bearing bidentate, falciger
blades; proximal tooth sligtly smaller than distal one.
pulsatoria include antennae about as long as the palps, a smooth anterior peristomial margin which is not projected, and homogomph falcigers
with short, slightly denticulated blades.
