Abstract Dung beetles exhibit a wide range of trophic preferences, including soft and hard resources. The study of mouthparts associated with these resources is extensive, and mouthparts of these insects have generally been described as membranous, hairy, and poorly adapted to cutting hard food. In this study, we compare the mouthparts (epipharynx, labium, and hypopharynx) of five species of Dichotomius Hope from Argentina that show differences in their trophic preferences, to evaluate if these structures also differ according to their feeding habit. We found epipharyngeal teeth, hypopharyngeal teeth, and more sclerotized structures in species that consume hard resources [Dichotomius carbonarius (Mannerheim)] and the absence or reduction of these structures in species that consume soft resources [Dichotomius sericeus (Harold), Dichotomius nisus (Olivier), Dichotomius mormon (Ljungh), and Dichotomius depressicollis (Harold)]. On the other hand, the latter species have hairier and softer mouth structures associated with these soft resources. According to these results, a detailed study of the macrostructures of mouthparts could indicate a priori the resource state consumed by a dung beetle species: the presence or absence of teeth and sclerotized structures would be associated with hard or soft food as the main resource, respectively, despite the occasional use of other resources in the field.

While working on the marine littoral Cafius Stephens (Coleoptera: Staphylinidae: Staphylininae), we found that Cafius cupreipennis (Cameron, 1918) and Cafius semiaereus (Cameron, 1934) correspond in many characters. Cameron (1934) also noted that these two species were similar except for the body coloration. This led us to study the taxonomic status of these two species in more detail. Examination of the types of C. cupreipennis and C. semiaereus (Fig. 1) deposited in the Natural History Museum (BMNH, London) revealed that they represent the same species. They share the same diagnostic characters as follows: glossy head and pronotum; subquadrate head and pronotum; pronotum with dorsal median longitudinal rows with 4–5 setiferous punctures; same pubescence and microsculpture pattern of pronotum (microsculpture and setae absent on dorsal surface); anterior-lateral corner of pronotum forming right angle; less dense setae on elytron. Based on these characters, we synonymize C. semiaereus under C. cupreipennis and provide illustrations of the diagnostic characters (Fig. 2) of C. cupreipennis. Specimens examined are from BMNH and Chungnam National University Insect Collection, Daejeon, South Korea (CNUIC). A backslash () was used between labels for label transcription notation.

Abstract Surveys for beetles and plant-associated insects on San Clemente Island off southern California conducted by the California Beetle Project and the Santa Barbara Botanic Garden found four specimens of an unknown bark beetle species. Based on morphology, the beetle was identified as a Carphobius Blackman species. Given the uncharacteristic scale-like setae, generic placement was confirmed in the context of a molecular phylogeny using partial sequences of COI and 28S genes. Carphobius was sister to Chaetophloeus LeConte (Chaetophloeini) which calls into question its current tribal placement in Polygraphini. Carphobius caterinoi Cognato and Smith, new species is described and compared to the three previously known Carphobius species and similar genera. Carphobius is reviewed and a key to species and images are included. Potential host use by C. caterinoi is discussed.
加州甲虫项目和圣巴巴拉植物园在加利福尼亚南部的圣克莱门特岛上对甲虫和植物相关昆虫进行了调查，发现了四种未知的树皮甲虫标本。根据形态学鉴定，该甲虫属于Carphobius Blackman种。考虑到非典型的鳞片状刚毛，利用COI和28S基因的部分序列进行分子系统发育，证实了其属位。Carphobius是Chaetophloeus LeConte (Chaetophloeini)的妹妹，这让人们对其目前在Polygraphini的部落位置产生了疑问。Carphobius caterinoi Cognato and Smith，描述了新种，并与已知的三个Carphobius种和相似属进行了比较。本文综述了Carphobius的种类和图像。讨论了毛虫对潜在寄主的利用。

Chaetocnema Stephens is a cosmopolitan genus of leaf beetles, with 75 species occurring in the Palearctic Region and over 400 species in all zoogeographical regions (Biondi et al. 2015; Konstantinov et al. 2011). All Palearctic Chaetocnema share the same diagnostic feature: having an obtuse tooth followed by an excavation on the middle and hind tibiae. However, they can be morphologically very similar and, in many cases, study of both genitalia (male and female) is necessary for exact species identification (Konstantinov et al. 2011; Konstantinov and Vandenberg 1996). Chaetocnema species generally inhabit moist environments or grasslands and are associated with several plants living in these habitats, particularly plants belonging to the families Chenopodiaceae, Polygonaceae, Cyperaceae, and Poaceae (Jolivet and Hawkeswood 1995). Chaetocnema wollastoni Baly, 1877 is a species associated with moist environments and was categorized with Pan-African and Afrotropical chorotypes, including Madagascar and the Arabian Peninsula (Biondi and D’Alessandro 2006). It was recently reported as new for the Italian fauna (Farina 2022). Its presence in the Asian part of the Palearctic is herein further supported based on records from Bolu, Turkey. Samples of C. wollastoni were collected from Göksu Natural Park in the province of Bolu, located in the northwest of Turkey (Fig. 1). The area, covering a total of 25 ha with an elevation of about 1,400 m, was declared a Natural Park by the government in 2011. Lake Aladağ, an artificial body of water, is within the boundaries of the park area, and the samples were collected from the vicinity of this lake. The specimens were collected by the second author during 2018, and recently identified to species by the first author, utilizing an Olympus SZ61 stereomicroscope and the taxonomic keys and figures given by Furth (1985a) and Biondi (2001). The aedeagus was cleaned after dissection and temporarily preserved in glycerin before imaging, and the spermatheca was placed in a drop of Euparal. The genitalia and habitus were photographed with a digital camera attached to a Zeiss Discovery-V8 stereomicroscope. All specimens are deposited in the personal collection of the first author at the Systematic Entomology Laboratory, Department of Biology, Süleyman Demirel University, Isparta, Turkey.
Chaetocnema Stephens是一种世界性的叶甲虫属，在古北地区有75种，在所有动物地理区域有400多种(Biondi et al. 2015;Konstantinov et al. 2011)。所有的古北毛囊瘤都有相同的诊断特征:在胫骨中部和后部有一个钝牙和一个挖掘。然而，它们在形态上可能非常相似，在许多情况下，对两个生殖器(雄性和雌性)的研究对于准确的物种识别是必要的(Konstantinov等人，2011;康斯坦丁诺夫和范登堡1996)。Chaetocnema物种通常生活在潮湿的环境或草原上，并与生活在这些栖息地的几种植物有关，特别是属于藜科、蓼科、柏科和禾科的植物(Jolivet and Hawkeswood 1995)。wollastoni Chaetocnema Baly, 1877是一种与潮湿环境有关的物种，被归类为泛非和非洲热带菌型，包括马达加斯加和阿拉伯半岛(Biondi和D 'Alessandro 2006)。它最近被报道为意大利动物群的新物种(Farina 2022)。在此，根据土耳其Bolu的记录，它在古北界亚洲部分的存在得到进一步的支持。wollastoni的样本采集于位于土耳其西北部的Bolu省Göksu自然公园(图1)。该区域总面积为25公顷，海拔约1400米，于2011年被政府宣布为自然公园。阿拉达胡湖是一个人工水体，位于公园区域的边界内，样本是从该湖泊附近收集的。该标本由第二作者于2018年采集，最近由第一作者利用Olympus SZ61立体显微镜和Furth (1985a)和Biondi(2001)给出的分类键和图进行了物种鉴定。解剖后将睾丸清洗干净，成像前暂时保存在甘油中，将精囊置于一滴Euparal中。用连接在蔡司Discovery-V8立体显微镜上的数码相机拍摄生殖器和体质。所有标本都存放在第一作者的个人收藏中，存放在土耳其伊斯帕塔莱曼德米雷尔大学生物系系统昆虫学实验室。
