The new genus Tropostreptus is erected to accommodate seven species which are all endemic in Tanzania: T. hamatus (Demange, 1977) (type species, = Spirostreptus hamatus Demange, 1977), T. sigmatospinus sp. nov., T. microcephalus sp. nov., T. droides sp. nov., T. kipunji spec. nov., T. austerus (Attems, 1950) (= Epistreptus austerus Attems, 1950) and T. severus sp. nov. All but one (T. sigmatospinus) of the species are restricted to the Eastern Arc Mts. in a wide sense, i.e., including Mt. Rungwe. Notes are included on Rickia gigas Santamaria et al., 2016 (Ascomycota: Laboulbeniales), which infects several Tropostreptus species. The typical, long-celled form of R. gigas grows on body parts of both sexes coming into contact during copulation, whereas a short-celled form also ascribed to R. gigas grows on the hind margin of body rings of both sexes. A key to Tropostreptus species is included.
新属Tropostreptus被建立以容纳7个物种，它们均为坦桑尼亚特有种：T. hamatus（Demange，1977）（模式种，= Spirostreptus hamatus Demange，1977）、T. sigmatospinus新种、T. microcephalus新种、T. droides新种、T. kipunji新种、T. austerus（Attems，1950）（= Epistreptus austerus Attems，1950）和T. severus新种。除了一个物种（T. sigmatospinus）外，所有物种都局限于广义的东弧山脉，即包括伦圭山。文中还提及了2016年Santamaria等人描述的Rickia gigas（子囊菌门：虫囊菌目），它可感染多种Tropostreptus物种。典型的长细胞型R. gigas生长在交配时两性接触的身体部位，而一种也被归为R. gigas的短细胞型生长在两性身体环带的后缘。文中还给出了Tropostreptus物种的检索表。
