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.","PeriodicalId":50668,"journal":{"name":"Coleopterists Bulletin","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46182288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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).

Carphobius was sister to Chaetophloeus LeConte (Chaetophloeini) which calls into question its current tribal placement in Polygraphini.

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.","PeriodicalId":50668,"journal":{"name":"Coleopterists Bulletin","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46016991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
