The Ecuadorian territory is divided into four natural regions: the coastal lowlands, the Andean highlands, the Amazon basin, and the Galapagos Islands. Each of these regions has its own ecosystems and specific vegetation. The purpose of this work is to compile an updated catalog of the Scarabaeinae (Coleoptera: Scarabaeidae) of Ecuador that includes distributional data and several nomenclatural acts. We compiled data from 25 scientific collections, with the examination of 13,550 scarabaeines; additionally, 390 bibliographic references were reviewed for their taxonomic histories. The Scarabaeinae fauna from Ecuador is represented by 33 genera and 223 species, with 45 range-restricted species; 27 species were erroneously recorded from the country. The following nomenclatural acts are made: (A) two new status as valid species: Canthon (Glaphyrocanthon) ohausi Balthasar, 1939,stat. n., and Deltochilum (Calhyboma) arrowi Paulian, 1939stat. n.; (B) one new synonym:UroxysmagnusBalthasar, 1940 =UroxyslatesulcatusBates, 1891,syn. n.; (C) two revalidated names: Canthidium (Canthidium) orbiculatum (Lucas, 1857) and Dichotomius (Luederwaldtinia) fortepunctatus (Luederwaldt, 1923); and (D) ten lectotypes designated for:ChoeridiumorbiculatumLucas, 1857;ChoeridiumcupreumBlanchard, 1846;CanthidiumcoerulescensBalthasar, 1939;CanthonangustatusHarold, 1867;CanthonangustatusohausiBalthasar, 1939;DeltochilumtessellatumBates, 1870;PinotusfortepunctatusLuederwaldt, 1923;PinotusglobulusFelsche, 1901;UroxyslatesulcatusBates, 1891; andUroxysmagnusBalthasar, 1940. The type specimens related to the new nomenclatural acts are illustrated and the maps of the geographical distribution of all species are provided.

The diversity of dung beetles is still underestimated in northeastern Brazil. Recent collections have revealed new records of the following species: Canthon histrio (Lepeletier de Saint-Fargeau & Audinet-Serville, 1828), Coprophanaeus acrisius (MacLeay, 1819), Coprophanaeus dardanus (MacLeay, 1819), Deltochilum alpercata Silva et al., 2015, Deltochilum brasiliense (Castelnau, 1840), Dichotomius gilletti Valois et al., 2017, Dichotomius iannuzziae Valois et al., 2017, Eurysternus calligrammus Dalman, 1824, Eurysternus parallelus Castelnau, 1840, Oxysternon silenus Castelnau, 1840, and Phanaeus splendidulus (Fabricius, 1781). These records are discussed in light of the known biogeography of each species.

“…A previous report showed this fragment of Atlantic Forest to have a high diversity of Scarabaeinae (Louzada & Lopes, 1997). Some of these beetle species are geographically limited to few localities, but are present in this fragment, such as the necrophagous tunnellers Dichotomius (Luederwaldtinia) louzadai Nunes, Carvalho, & Vaz-de-Mello, 2016(Nunes et al, 2016, and Coprophanaeus (Megaphanaeus) bellicosus (Olivier 1789) (Edmonds & Zidek, 2010;Maldaner et al, 2017); as well as the rollers Deltochilum (Hybomidium) louzadai González-Alvarado & Vaz-de-Mello, 2014(González-Alvarado & Vaz-de-Mello, 2014 and De. (Parahyboma) furcatum (Castelnau 1840) (Almeida, Corrêa, & Grossi, 2015), the latter of which was reported as the most abundant of these necrophagous Scarabaeinae in the first study of this community (Louzada & Lopes, 1997) and remains so to this day (VSF pers.…”

Nesting strategies and disease risk in necrophagous beetles

While the effects of carcass decomposition on microorganisms have been demonstrated in recent years, little is known of how this impacts necrophagous insects. A common assumption is that insects that exploit carcasses are exposed to a high density of potentially harmful microorganisms, but no field data have so far validated this. Necrophagous beetles such as the Scarabaeinae have complex nesting behaviors with elaborate parental care. So here, we begin to explore whether this conjunction of life history and nesting behavior represents an adaptive response to the threat posed by microbes in these environments, mainly by entomopathogens. We evaluated the density and distribution of fungi and bacteria from soil near the carcasses, and their ability to infect and kill insects that are in contact with this soil during the decomposition process. Our data showed an increase in the density and activity of opportunistic or facultative pathogens during the apex of decomposition, when there is a predominance of necrophagous insects. Meanwhile, the survivorship of bait insects decreased when in contact with soil from this period of decomposition, indicating a potential risk of infection. However, the density and activity of these microorganisms decreased with distance from the carcass, mainly with depth, which would benefit tunneller beetles in particular. We have thus provided the first field data to show that necrophagous insects are indeed exposed to high densities of potentially harmful microorganisms. Furthermore, we propose that some parental care strategies may have arisen not only as a response to competition, but also as adaptations that reduce the risks of disease. Although we have focused on carrion feeders, we suggest that the same occurs with coprophagous beetles, as both carrion and dung are nutrient‐rich resources.
