Procryptotermes Holmgren is a modestly diverse kalotermitid genus endemic to numerous islands and archipelagos of the world's tropical oceans (Scheffrahn Křeček 2001). Mainland records from southern India (Bose 1979, Roonwal Chhotani 1963, Thakur 1975), Queensland Australia (Watson and Abbey 1993), and the Yucatan Peninsula (Scheffrahn and Křeček 2001), also approximate oceanic coastlines. The soldier of Procryptotermes is distinguished from most other kalotermitids by long, sickle-shaped mandibles and a rather weak or absent frontal flange or protuberance (Krishna 1961). The winged imago of Procryptotermes is similar to that of Cryptotermes Banks in which the median vein is unsclerotized and intersects the radial sector near mid-wing. Of the fourteen described species of Procryptotermes (Scheffrahn Křeček 2001), only one species, P. dioscurae Harris 1954, lacks a description of the soldier caste. It was described from three winged imagos collected from lights on Socotra Island, Yemen. Unlike soldiers, the imago caste is not present in the colony year round and often lacks species-level diagnostic characters. Therefore, the description of the soldier caste is highly desirable for most termite species.
原白蚁属(Procryptotermes Holmgren)是一个多样性相对较低的木白蚁科属,分布于世界热带海洋的众多岛屿和群岛(谢夫拉恩和克雷切克,2001年)。来自印度南部(博斯,1979年;鲁恩瓦尔和乔塔尼,1963年;塔库尔,1975年)、澳大利亚昆士兰(沃森和阿比,1993年)以及尤卡坦半岛(谢夫拉恩和克雷切克,2001年)的大陆记录,也都靠近海洋海岸线。原白蚁属的兵蚁与大多数其他木白蚁科属的区别在于,其具有长而呈镰刀状的上颚,以及相当薄弱或没有的额缘或额突(克里希纳,1961年)。原白蚁属的有翅成虫与截头白蚁属(Cryptotermes Banks)的相似,其中脉未硬化,且在翅中部附近与径脉相交。在已描述的14种原白蚁属物种中(谢夫拉恩和克雷切克,2001年),只有一种物种,即1954年哈里斯描述的暗褐原白蚁(P. dioscurae),没有兵蚁品级的描述。它是根据从也门索科特拉岛灯光处采集到的三只带翅成虫描述的。与兵蚁不同,成虫品级并非全年都存在于蚁群中,且通常缺乏物种水平的诊断特征。因此,对于大多数白蚁物种来说,兵蚁品级的描述是非常必要的。
