位于纳米比亚北部的Macrotermes Michaelseni(Sjostedt)土丘具有独特的建筑结构，分为三个结构截然不同的部分：中央锥形土丘，顶部有一个又高又细的尖顶，向北倾斜的角度与太阳的平均天顶角相似；以及一个宽阔的外露山墙，它是由于土丘的侵蚀而产生的。在内部，土丘被一个复杂的隧道网络所渗透，这些隧道可以分为三大类型：一个宽敞的中央烟囱，从殖民地向上穿过土丘中心，直到尖顶；一个垂直倾斜的地表管道网络，大约在地表以下一到两厘米处；以及一个交织的横向隧道网络，连接烟囱和地表管道。提出了一个能够解释这些结构特征的土丘形态发生模型，并指出了土丘结构与大型白蚁社会动态平衡之间关系的一般模型。
The mounds of Macrotermes michaelseni (Sjostedt) in northern Namibia have a characteristic architecture, being divided into three structurally distinct components: a central cone-shaped mound, topped by a tall, thin spire which tilts northward at an angle similar to the sun's average zenith angle, and a broad outwash pediment that results from erosion off the mound. Internally, the mound is permeated by a complex network of tunnels that can be divided into three broad types: a capacious central chimney that extends upward through the center of the mound from the colony up to the apex of the spire; a vertically-biased network of surface conduits that lies roughly one to two cm below the surface, and an interweaving network of lateral tunnels that connect the chimney and surface conduits. A model of mound morphogenesis is proposed which accounts for most of these structural features, and which points toward a general model for the relationship between mound architecture and social homeostasis among the macrotermitine termites.
