Водобродка (лат. Hydraena) — род жуков-водобродок из подсемейства Hydraeninae. Встречаются повсеместно. Крупнейший род семейства, в котором известно около 1000 видов.

Распространение

Встречаются повсеместно. Для СССР указывалось не менее 12 видов, на Дальнем Востоке России 2 вида (Hydraena flavomarginata и Hydraena riparia). Крупнейшая региональная фауна отмечена в Папуа — Новой Гвинее (132 вида) и на Мадагаскаре (106 видов).

Описание

Водобродки мелкого размера (1—3 мм), удлинённой формы. Усики состоят из девяти-одиннадцати члеников со слабо выраженной четырех- или пятичлениковой булавой. Щупики (ротовые щупальца) намного длиннее усиков. Взрослые жуки растительноядные, личинки плотоядные.

Род Hydraena хорошо определяется следующими аутапоморфными характеристиками: 1) наличие лабрально-мандибулярного сцепления, 2) ментум с острым срединным выступом, 3) различные сложные сенсиллы, и 4) специализированные особенности экзокринной выделительной системы (ESDS). Современные специалисты в целом согласны с тем, что Hydraena является монофилетичным.

Голова сверху мелкопунктированная. Тазики средних и задних ног раздвинутые. В очень длинных нижнечелюстных щупиках 4 сегмента, нижнегубные щупики 3-члениковые. Лапки пятичлениковые, но иногда кажутся 3- или 4-члениковыми из их редукции. Встречаются в текучих, а также стоячих водоёмах (в озёрах и долинах рек).

Классификация

Крупный род жуков, известно около 1000 видов но многие виды остаются неописанными. Род Hydraena был выделен в 1794 году немецким энтомологом Johann Gottlieb Kugelann (1753—1815) для вида Hydraena riparia Kugelann, 1794.
