Abstract

Helochares (Hydrobaticus) MacLeay, 1871 is the largest subgenus of Helochares Mulsant, 1844. The Chinese fauna of Helochares (Hydrobaticus) is still poorly known. Five species are recognized, including three herein described as new: Helochares (Hydrobaticus) hainanensis sp. n. (Hainan); H. wuzhifengensis sp. n. (Jiangxi); H. tengchongensis sp. n. (Yunnan). Helochares minor d'Orchymont, 1925 and H. nipponicus Hebauer, 1995 are recorded from China for the first time. Descriptions, diagnoses, and illustrations of the new species are given. Habitus and aedeagus photos of the new record species are provided.

摘要

麦氏 (Hydrobaticus) 长蝽属（Helochares）是 1871 年由 MacLeay 建立的，是 1844 年由 Mulsant 建立的长蝽属（Helochares）中最大的亚属。中国的麦氏 (Hydrobaticus) 长蝽属区系仍知之甚少。本文共记述 5 种，其中 3 种为新种：海南麦氏 (Hydrobaticus) 长蝽（Hainan）、武夷山麦氏 (Hydrobaticus) 长蝽（Jiangxi）和腾冲麦氏 (Hydrobaticus) 长蝽（Yunnan）。此外，本文还首次记录了中国的 2 种：奥氏麦氏 (Hydrobaticus) 长蝽（Helochares minor d'Orchymont，1925）和日本麦氏 (Hydrobaticus) 长蝽（Helochares nipponicus Hebauer，1995）。本文对新种进行了描述和绘图，并提供了新记录种的整体和外生殖器照片。
