The genus Habetia Kirby, 1906 previously known from only four species or subspecies is revised based on unidentified specimens found in museum collections. H. multispinulosa Griffini, 1908 is given full species status, while H. pictifrons Karny, 1911 is removed from Habetia based on male and female characters and becomes the type species of the new genus Parahabetia gen. nov. Sixteen new species are described in Habetia, and one new species and two new subspecies in Parahabetia. The most significant characters for the differentiation of species of Habetia are male tenth abdominal tergite, cerci, subgenital plate, and male internal genitalia with the titillators that basically form a pair of roughly U-shaped sclerites that vary between species from simple, curved sclerites to modified structures with additional sclerotized branches and the sclerites can be connected with septa to form complex shapes. In contrast, males of Parahabetia have elongate titillators provided at end with a crest. In the larger species of Habetia the stridulatory file on the underside of the male left tegmen has a step in pre-apical area that is missing in the smaller species; one species with a weak step is intermediate between both groups. Unique modifications of single species in Habetia are an apical dorsal extension of the male subgenital plate in H. imitatrix Karny, 1912 and a hardened phallus sheath between phallus and subgenital plate in H. tuta sp. nov. Females of Habetia have straight ovipositors that vary in length and in the shape of the dorsal margin between species. Females can also be differentiated by species specific modifications of the subgenital plate. In Parahabetia the ovipositor is rather short and curved similar to the condition in the genus Philmontis Willemse, 1966 but has the apical area slightly recurved. Keys to the species of both genera are provided. Habetia species have been found throughout New Guinea except so far for Papua Barat; although they were mainly found in the North and the East. Parahabetia species are currently only known from the East of New Guinea. The following species and subspecies are described as new: Habetia bivittata sp. nov., H. curvata sp. nov., H. dentata sp. nov., H. elevata sp. nov., H. kondiu sp. nov., H. lalibu sp. nov., H. nigricauda sp. nov., H. pallida sp. nov., H. pedala sp. nov., H. pilleata sp. nov., H. pinnigera sp. nov., H. quatrispina sp. nov., H. simbai sp. nov., H. sororcula sp. nov., H. tuta sp. nov., H. wau sp. nov., Parahabetia bispinosa sp. nov., P. pictifrons obtusa ssp. nov., P. pictifrons acuta ssp. nov.
基于博物馆馆藏的未鉴定标本，对先前仅知的四个种或亚种的 Habetia Kirby, 1906 属进行修订。将 Griffini, 1908 年的 H. multispinulosa 提升为全种地位，而 Karny, 1911 年的 H. pictifrons 则因雄性和雌性特征而从 Habetia 中移除，并成为新属 Parahabetia 的模式种。在 Habetia 中描述了 16 个新种，在 Parahabetia 中描述了 1 个新种和 2 个新亚种。区分 Habetia 属物种的最显著特征是雄性第十腹节、尾须、生殖器侧板和雄性内部生殖器，其上的触须基本形成一对大致呈 U 形的硬化片，在物种之间从简单、弯曲的硬化片到具有附加硬化分支的改良结构变化，这些硬化片可以通过隔膜连接形成复杂的形状。相比之下，Parahabetia 的雄性具有末端带有脊的细长触须。在较大的 Habetia 物种中，雄性左翅腹板下的摩擦发声器在前尖区域有一个阶，而在较小的物种中则缺失；一种具有较弱阶的物种位于两个组之间的中间。Habetia 中单个物种的独特变异包括 Karny, 1912 年的 H. imitatrix 雄性生殖器侧板的顶部背侧延伸和生殖器侧板和生殖器之间的硬化阴茎鞘。Habetia 的雌性具有直的产卵器，在物种之间长度和背缘形状有所不同。雌性还可以通过特定于物种的生殖器侧板的修饰来区分。在 Parahabetia 中，产卵器相当短且弯曲，类似于 Philmontis Willemse, 1966 属中的情况，但顶端区域稍微向后弯曲。提供了两个属的物种的关键。除了巴布亚新几内亚的西巴布亚省以外，新几内亚各地都发现了 Habetia 物种；尽管它们主要分布在北部和东部。目前仅在新几内亚东部发现了 Parahabetia 物种。以下物种和亚种被描述为新种：Habetia bivittata sp. nov.、H. curvata sp. nov.、H. dentata sp. nov.、H. elevata sp. nov.、H. kondiu sp. nov.、H. lalibu sp. nov.、H. nigricauda sp. nov.、H. pallida sp. nov.、H. pedala sp. nov.、H. pilleata sp. nov.、H. pinnigera sp. nov.、H. quatrispina sp. nov.、H. simbai sp. nov.、H. sororcula sp. nov.、H. tuta sp. nov.、H. wau sp. nov.、Parahabetia bispinosa sp. nov.、P. pictifrons obtusa ssp. nov.、P. pictifrons acuta ssp. nov.。
