Campylomorphus homalisinus (Elateridae): a new species for Lombardy (Italy), with notes on its ecology, distribution and biogeography

Campylomorphus homalisinus has been found on Mt. Lesima (Northern Apennines) and it is the first record for the Lombardy region. C. homalisinus is a rare orophilous species: it has a discontinuous chorology that may have been caused by glaciers dynamics during the Pleistocene era. Little is known about the ecology of the species. This record and the expert-based investigation we performed determined that C. homalisinus inhabits shrublands and grasslands, but may also occur in the forests. This survey includes the only record of C. homalisinus foraging on flowers, a behavior that is not rare in the family Elateridae. We hypothesize that adults integrate their diet with flower resources according to a generalist strategy.

Campylomorphus homalisinus 已在莱斯马山（北亚平宁山脉）被记录发现，这标志着该物种在伦巴第地区的首次记录。Campylomorphus homalisinus 是一种稀有或喜湿润的物种：其分布地理学呈现不连续性，这种分布可能由更新世时期的冰川动力学所引起。关于该物种的生态学知识极为有限。本记录以及我们所进行的基于专家的调查研究确定，C. homalisinus 栖居于灌木丛和草地，但也可能出现在森林中。本次调查包括了对 C. homalisinus 在花朵上觅食的唯一记录，这一行为在 Elateridae 科中并不罕见。我们假设成虫根据泛食性策略，将花资源整合到其饮食中。
