Cetoniinae is one of the showiest scarab groups, exhibiting bright‐metallic body colors, and usually attract great attention from entomologists and amateur collectors. Larvae of Cetoniinae show dramatically diversity on morphology and living habits. Although being considered one of the best‐studied groups of Scarabaeidae, larvae have been described for less than 5% species to the known Cetoniinae. In this study, the final instar larva of Lasiotrichius succinctus hananoi was described using scanning electron microscopy. The larvae are peculiar for bearing a haptomeral process dividing 10 spines into two groups: six on the left side, four on the right side, different from the previous descriptions on L. succinctus (Pallas, 1781). The morphological differences under SEM imply the further requirement of taxonomic revision in Lasiotrichius. Both advantage and disadvantage of SEM utilizing in larval descriptions were briefly discussed.

使用扫描电子显微镜对 Lasiotrichius succinctus hananoi（Sawada）（鞘翅目：金龟科：Cetoniinae：Trichinii）的三龄幼虫进行形态学描述。

Cetoniinae 是最引人注目的圣甲虫群体之一，呈现出明亮的金属体色，通常会引起昆虫学家和业余收藏家的极大关注。Cetoniinae 的幼虫在形态和生活习性上表现出极大的多样性。尽管被认为是金龟科中研究最充分的群体之一，但据描述，幼虫的种类少于已知的鲸亚科的 5%。在这项研究中，使用扫描电子显微镜描述了Lasiotrichius succinctus hananoi的最终龄幼虫。幼虫具有独特的触角突起，将 10 根刺分成两组：左侧 6 根，右侧 4 根，与之前对L. succinctus 的描述不同（帕拉斯，1781 年）。扫描电镜下的形态差异意味着对Lasiotrichius分类学修订的进一步要求。简要讨论了 SEM 在幼虫描述中的优点和缺点。
