Abstract Two new species of the genus Esakia Lundblad, 1933 are described, both from Borneo: Esakia borneensis sp. n. and E. mazzoldii sp. n. For the first time, E. johorensis Cheng, 1966 is reported from Sumatra; E. hungerfordi Miyamoto, 1967 from Sarawak and Sabah; and E. lundbladi Cheng, 1966 from Thailand (Narathiwat Province). The taxonomy of E. kuiterti Hungerford and Matsuda, 1958 and E. hungerfordi is discussed. Esakia hungerfordi, previously considered by Polhemus (1992) as a synonym of E. fernandoi, is treated here as a separate species from the latter. Easkia kuiterti, which was also synonymised with E. ventidioides Lundlblad, 1933 by Polhemus (1992), is considered valid species. http://zoobank.org/urn:lsid:zoobank.org:pub:F6E94274-2305-4096-9186-2D799124E2FA

Esakia Lundblad 属的分类学研究，1933（异翅目：Gerromorpha：Gerridae），描述了来自婆罗洲的两个新物种

摘要 描述了 1933 年 Esakia Lundblad 属的两个新物种，它们都来自婆罗洲：Esakia borneensis sp.。n. 和 E. mazzoldii sp。n. E. johorensis Cheng, 1966 首次从苏门答腊报道；E. Hungerfordi Miyamoto，1967 年来自砂拉越和沙巴；和 E. lundbladi Cheng，1966 年来自泰国（那拉提瓦省）。讨论了 E. kuiterti Hungerford 和 Matsuda，1958 和 E. Hungerfordi 的分类。Esakia Hungfordi 以前被 Polhemus (1992) 视为 E. fernandoi 的同义词，在这里被视为与后者不同的物种。Easkia kuiterti，也被 Polhemus (1992) 于 1933 年与 E. ventidioides Lundlblad 同义，被认为是有效物种。http://zoobank.org/urn:lsid:zoobank.org:pub:F6E94274-2305-4096-9186-2D799124E2FA
