Scarabaeinae specimens were collected with the use of pitfall traps baited with human excrement, rotten meat and rotting banana, between May 2009 and April 2010, in three forest fragments in Santa Maria, Rio Grande do Sul, Brazil: 'Morro do Elefante' (MOEL), 'Morro do Cerrito' (MOCE) and 'Campus da Universidade Federal de Santa Maria' (UFSM). A total of 19,699 individuals belonging to 33 species were collected. Canthidium aff. trinodosum Boheman, 1858, Canthon latipes Blanchard, 1845, Dichotomius assifer (Eschscholtz 1822), Eurysternus caribaeus (Herbst 1789), Canthidium sp. and Canthon lividus Blanchard, 1845, were the most abundant species. MOEL showed the greatest richness, MOCE the greatest abundance, while UFSM showed the lowest values of richness and abundance. The greatest similarity (qualitative and quantitative) was found between MOEL and MOCE, while the lowest occurred between MOCE and UFSM. Only 51% of the species were common to all three fragments. The richness and abundance of Scarabaeinae were positively correlated with the air temperature. The richness of the fragment decreased according to the smaller size and the greater degree of disturbance of vegetation structure.
2009年5月至2010年4月期间，在巴西南里奥格兰德州圣玛丽亚的三个森林片段中，即“大象山”（MOEL）、“塞罗里托山”（MOCE）和“圣玛丽亚联邦大学校园”（UFSM），使用装有人类粪便、腐肉和腐烂香蕉的陷阱诱捕器收集了金龟子亚科标本。共收集到19699个个体，分属于33个物种。近似三瘤坎土甲Canthidium aff. trinodosum Boheman, 1858、宽足扁角金龟Canthon latipes Blanchard, 1845、具角双叉犀金龟Dichotomius assifer (Eschscholtz 1822)、加勒比真犀金龟Eurysternus caribaeus (Herbst 1789)、坎土甲属Canthidium sp.以及青黑扁角金龟Canthon lividus Blanchard, 1845是最为丰富的物种。MOEL的物种丰富度最高，MOCE的个体数量最多，而UFSM的丰富度和数量值最低。MOEL和MOCE之间的相似性（定性和定量）最大，而MOCE和UFSM之间的相似性最小。所有三个片段中只有51%的物种是共有的。金龟子亚科的丰富度和数量与气温呈正相关。片段的丰富度随着面积减小和植被结构干扰程度增加而降低。
