小丸甲科(Nosodendridae)隶属于鞘翅目(Coleoptera)长蠹总科(Bostrichoidea),是一类活动于树木伤口处,取食流出的汁液的小型甲虫。目前已知的小丸甲科昆虫共3属98种,分布于除南极洲外的各个大洲,其中大部分物种主要分布于热带地区,而温带地区较少记录。迄今为止,该科于我国记录有2属3种,分布于湖北、河南、云南和台湾[1-7]。小丸甲体型较小,虫体卵圆形,强凸;触角第3节明显伸长,末端膨大;后胸腹板很宽,中足基节远离,腹面有凹槽,足可收于凹槽中,跗节5-5-5式;可见腹板5节,腹板前缘具明显纵向沟[8-9]。多栖息于流出汁液的树皮附近,取食树汁,疑似群居,采集时常同时发现成虫与幼虫。

摘要: 2020年的野外考察中,于山东省采集到小丸甲科(Nosodendridae)的甲虫,该科未曾在山东有记录,因此对其进行鉴定与描述。对其成虫进行解剖后根据其形态学特征进行鉴定,并在野外观察其生活状态。经鉴定该种为台湾小丸甲(Nosodendron taiwanense Yoshitomi, Kishimoto & Lee, 2015),这是本种首次记录于中国大陆地区,同时也是小丸甲科在山东省的首次记录。本文对该种进行了重新描述,并且对其生态与行为学信息进行了补充。Abstract: During a field investigation in 2020, some beetles of Nosodendridae were found in Shandong province, which was not recorded in Shandong province. In this paper, the species was identified and described. After dissecting the adults, the species was identified according to their morphological characteristics, and their living conditions were observed in the field. This species was identified as Nosodendron taiwanense Yoshitomi, Kishimoto & Lee, 2015 (Coleoptera, Bostrichoidea: Nosodendridae). The specie was first recorded in China mainland, and the family was also first recorded in Shandong province. In this paper, the species was redescribed and its ecological and behavioral information was supplemented.was redescribed and its ecological and behavioral information was supplemented.was redescribed and its ecological and behavioral information was supplemented.was redescribed and its ecological and behavioral information was supplemented.
