翻译后摘要：目前的甲虫家庭Coptoclavidae由四个亚科已知的上三叠世-下白垩纪（Aptian）。本文描述了产于西班牙早白垩世巴雷阶（Barremian）的Las Hoyas（昆卡省）和El Montsec（莱利达省）的两个新亚科、三个新属和五个新种：第一个新亚科Hispanoclavinae来自Las Hoyas，包括一个新属Hispanoclavinae和两个新种H. diazromerali和H.第二种为Coptoclaviscinae，在El Montsec发现Coptoclavella（C. gratshevi）一新种。inexpecta）。此外，在Las Hoyas，Necronectinae和Coptoclavinae亚科各有一个新属和新种：Ovonectes pilosum和Hoyaclava buscalionae。所有以前被分配到家庭Coptoclavidae甲虫已被解释为积极的猎人。然而，我们认为Hispanoclavia和Hoyaclava是滤食性的，前肢适合过滤水面上和水面下的浮游生物（可能是浮游动物，因为该家族的其他成员是肉食性的）。这代表了甲虫（现存和灭绝）的一种新的进食策略。这五个新种将Coptoclavidae的已知地理分布扩展到欧洲Barremian矿床的西部。拉斯霍亚斯地区现在拥有已知最高的coptoclavid物种多样性。
Abstract: Currently the beetle family Coptoclavidae consists of four subfamilies known from the Upper Triassic–Lower Cretaceous (Aptian). We describe two new subfamilies, three new genera and five new species from the Las Hoyas (Cuenca Province) and El Montsec (Lleida Province) localities of Barremian (Early Cretaceous) age from Spain: the first new subfamily, Hispanoclavinae, is from Las Hoyas and comprises one new genus, Hispanoclavina, and two new species, H. diazromerali and H. gratshevi; the second, Coptoclaviscinae, is represented at El Montsec by one new species of Coptoclavella (C. inexpecta). In addition, at Las Hoyas the subfamilies Necronectinae and Coptoclavinae are each represented by one new genus and species: Ovonectes pilosum and Hoyaclava buscalionae, respectively. All beetles previously assigned to the family Coptoclavidae have been interpreted as active hunters. However, we consider Hispanoclavina and Hoyaclava to be filter‐feeding, with forelegs adapted for filtering plankton (probably zooplankton because other members of the family are carnivorous) on and beneath the water surface. This represents a new feeding strategy in beetles (extant and extinct). The five new species extend the known geographical distribution of the Coptoclavidae into the western part of European Barremian deposits. The Las Hoyas locality now has the highest known diversity of coptoclavid species.
