Diversity of feeding habits characterizes the dung beetle groups of the Neotropics, and undoubtedly contributes to to the high species richness of this region (Gill, 1991). Feeding habits determine some ecological aspects (Halffter, 1959) of scarabaeids, like behavior, distribution, morphology and development (Halffter & Matthews, 1966). This paper studies scarabaeine bait preferences in a dry forest patch and its surrounding matrix. 22 species were captured, with 6 new records for the area. The bait with the highest preference rating was omnivore dung, followed by carrion, fungi, cow dung and rotting fruit. The species with the highest abundance was Dichotomius ca. centralis, with 758  individuals and a copro-necrophagous diet. Its dominance was not restricted to the forested area, and significant numbers were found at the pasture matrix. Strict diet species like Deltochilum valgum agropyge were also collected. The dung beetle community observed was mostly generalist (71%), possibly due to the scarcity of excrement, which forces individuals to use other sources of food with a similar nutritional value.10aColombia10adiet10adry forest10apreferences10aresources10aScarabaeinae10aTolima1 aLida, Fernanda, Bustos-Gom1 aToro, Alejandro, Lopera  uhttps://scarabnet.myspecies.info/preferencia-por-cebo-de-los-escarabajos-coprofagos-coleoptera-scarabaeidae-scarabaeinae-de-un-remane01481nas a2200181   4500008004100000245006200041210006000103260000800163300001000171490000600181520091700187653001101104653001801115653002301133100002501156700002501181856009301206       2003                        eng d00aDimorfismo sexual en larvas de Scarabaeoidea (Coleoptera)0 aDimorfismo sexual en larvas de Scarabaeoidea Coleoptera  csep  a15-180 v33 aA well defined sexual dimorphism is present in scarabaeoid larvae. Dimorphism was observed in late-age larvae of some species of Scarabaeidae, Aphodiidae, Trogidae, Orphinidae, Dynastidae, Passalidae and Lucanidae. This dimorphism manifests itself in the presence of a terminal ampulla, a cuticular structure situated in the ventral region of the 9th abdominal segment which is only present in male specimens. In Scarabaeidae, sexual dimorphism was only observed in the pupae of six species. The terminal ampulla in Canthon cyanellus cyanellus LeConte (Scarabaeidae) is present in the male larvae apparently since the first instar, and changes morphologically during the next larva instars. Only a detailed study of the morphogenesis of the terminal ampulla during the larval and pupal stages could help to define exactly what structures of the ejaculatory bulb and aedeagus it will turn into in the adult stage.10alarvae10aScarabaeoidea10asexual dimorphism.1 aM., Imelda, Martinez1 aLumaret, Jean-Pierre  uhttps://scarabnet.myspecies.info/dimorfismo-sexual-en-larvas-de-scarabaeoidea-coleoptera02770nas a2200241   4500008004500000245011300045210006900158260000800227300001000235490000600245520190200251653003002153653001502183653002902198653001502227653002602242653003402268653002902302653001702331100002402348700001802372856013802390       2003                        spandsh  00aSobre el comportamiento de alimentacion y nidificacion de Eucraniini (Coleoptera Scarabaeidae: Scarabaeinae)0 aSobre el comportamiento de alimentacion y nidificacion de Eucran  csep  a75-800 v33 aIn this study we report upon the analysis of food relocation and nesting behaviour of some species of the Tribe Eucraniini sensu Zunino, 1985 (Coleoptera: Scarabaei- dae), endemic to the arid and semiarid areas of Argentina, namely Ennearabdus lobocephalus (Ennearabdina), Anomiopsoides heteroclyta, Glyphoderus sterquilinus and Eucranium arachnoides (Eucraniina). Observations, carried out either under field conditions [Salta (Cafayate), La Rioja (Chamical), Mendoza (Ñacuñán), Córdoba (Chancaní), San Luis (Juan Jorba, La Punilla)], or in experimental breeding boxes (Chamical, Chancaní and Río Cuarto) placed in natural conditions, allowed us to obtain data concerning the rhythms of adults activity, locomotion behaviour, food manipulation and nest structure. Ennearabdus lobocephalus, the only flying species, very scarce, exploits different kinds of fresh or semifresh excrement and, seemingly, is nocturnal, hypophagic and paracoprid. The Eucraniina, which are apterous or micropterous, diurnal, heliophi- lous, telephagic and telecoprid, feed excusively on dehydrated dung, generally from rodents and camelids, alternatively from domestic herbivores. Food relocation, mainly horizontal, is performed by the specimen using movements and postures which may change depending on the size of the fragment; however, the food relocation pattern is typical and exclusive of the group. Our observations included also some cases of vertical relocation, just beneath the food source, and even rare events of direct feeding without a previous relocation. Differences both in locomotion behaviour and food handling have been observed. The comparison of the obtained data, altough preliminary and incomplete, leads us to hypothesize the occurrence of a remarkable ethological plasticity in Eucranium arachnoides, higher than that of Anomiopsoides heteroclyta and Glyphoderus sterquilinus.10aAnomiopsoides heteroclyta10aArgentina.10aEnnearabdus lobocephalus10aEucraniini10aEucranium arachnoides10afeeding and nesting behaviour10aGlyphoderus sterquilinus10aScarabaeinae1 aMonteresino, Estela1 aZunino, Mario  uhttps://scarabnet.myspecies.info/sobre-el-comportamiento-de-alimentacion-y-nidificacion-de-eucraniini-coleoptera-scarabaeidae-scaraba02876nas a2200205   4500008004100000245005100041210005100092260000800143300000900151490000600160520229200166653003002458653001502488653001602503653001202519653001702531653001802548100002002566856008402586       2003                        eng d00aHistoria de la Escarabaeidologia en el Ecuador0 aHistoria de la Escarabaeidologia en el Ecuador  csep  a9-140 v33 aThe history of Entomology in Ecuador is deeply related to Spain’s socio-cultural heritage. Unlike other countries of the New World, which benefited from the flow of scientistis migrating from Europe escaping from the difficult situations of the last two centuries, our country was not affected by this contribution, thus remaining isolated from the entomological point of view. However, from 1800 to the present day, Ecuador has been the destination of several scientific expeditions and occasional visits of entomologists who contributed remarkably to the knowledge of the country’s extraordinary scarabaeidological fauna.The main routes followed by scientists were: Guayaquil-Ventanas-Riobamba-Quito; Guayaquil-Molleturo-Cuenca; the inter- Andean Valley from Tulcán to Loja; Cuenca-Sigsig-Gualaquiza, and Baños-Puyo- Río Bobonaza-Río Pastaza up to Amazonía. Only in the last two decades, with the coming of the "oil age", have new routes of access to the Amazonian basin been opened. Entomological research was mainly funded by the countries of the Northen hemisphere and as a consequence the specimens were taken to the countries promoting entomological collections.Our Scarabaeoidea are in numerous foreign museums. Recently, in Ecuador have been established the QCAZ (Quito Católica Zoología) and MECN (Museo Ecuatoriano Ciencias Naturales) museums, which contain representative collections of Scarabaeoidea. Since 1980, the professional training of entomologists, who have contributed remarkably to the preparation of collections and analysis of specimens, has laid the foundations of the development of scarabeidology in our country. The chaotic growth of oil-related and agricultural activities, along with the construction of a capillary road network, has brought about the colonization of large areas and, as a consequence, the destruction of the natural habitat. It's urgent to intensify scarabeidological investigations in areas not yet explored, before our entomological richness disappears once and for all. It is extremely important also to rescue the scarabeoidological indigenous knowledge, which, although not included in the traditional scientific frame, certainly represents a great amount of ancestral wisdom and is a valuable heritage of mankind. 10abibliographical synthesis10aCOLEOPTERA10acollections10aEcuador10aexplorations10aScarabaeoidea1 aOnore, Giovanni  uhttps://scarabnet.myspecies.info/historia-de-la-escarabaeidologia-en-el-ecuador01756nas a2200217   4500008004100000245015200041210006900193300001000262490000600272520092900278653001701207653001401224653001701238653001401255653001701269100002901286700002801315700002801343700002901371856013801400       2003                        eng d00aEscarabajos coprofagos (Coleoptera: Scarabaeidae: Scarabaeinae) del Parque Nacional Natural "Serrania de Chiribiquete", Caqueta, Colombia (Parte I)0 aEscarabajos coprofagos Coleoptera Scarabaeidae Scarabaeinae del   a51-580 v33 aWithin the project “Elaboration and implementation of the management plan of the Chiribiquete Natural Park” dung beetles (Coleoptera: Scarabaeidae Scarabaeinae) are being used  as an indicator group and also to establish similarities or differences between the landscape units of the Chiribiquete Natural Park. The results of the preliminary paper are given, which include  the first two expeditions launched  to the Mesay river basin, with five landscape units, and to the Sararamano river basin, with six landscape units. These landscape units were established with satellite images identified by color. A total of 4,620 individuals from 61 species and 14 genera were collected; there are differences, for  the richness and diversity values, between landscape units, and also the complementarity index shows differences between  some landscape units. Seven new species are new records for the Colombian Guyana region. 10aChiribiquete10adiversity10aDung beetles10alandscape10aScarabaeidae1 aHerrera, Luz, Astrid Pul1 aCanas, Raul, Antonio Ri1 aHarders, Fernando, Gast1 avon Hildebrand, Patricio  uhttps://scarabnet.myspecies.info/escarabajos-coprofagos-coleoptera-scarabaeidae-scarabaeinae-del-parque-nacional-natural-serrania-de-01971nas a2200193   4500008004100000245009600041210006900137300001200206490000600218520131000224653001101534653001501545653001701560653001501577653001701592653001301609100003101622856012401653       2000                        eng d00aEstado atual do conhecimento dos Scarabaeidae s. str.

The aim of this work is to determine the present degre of taxonomic and faunistic knowledge of Brazilian species in this group. Between 1926 and 1998, 62 papers dealing with Brazilian Scarabaeidae Systematics have been published by 12 Brazilian researchers. Thirteen local or regional faunal lists have been published between 1875 and 1999. There are by now two Brazilian researchers publishing on the Systematics of Brazilian Scarabaeidae s. str. 618 species are cited as occurring in Brazil, 223 endemic to this country. Just five genera, out of the 49 occurring in Brazil, have been reviewed made in the last two decades. The study of a big collection showed 768 Brazilian species of Scarabaeidae, 41% identified to the species level, 8% new and the others unidentifiable without examining types or reviewing genera. Similar proportions have been found in unpublished data from 25 faunal listings in eight states. We conclude that the main limitations of the study of this group in Brazil are the many undersampled areas and the low number of researchers working on the Taxonomy of this group. The Appendix presents a preliminary list of species known to occur in Brazil. 10aBrasil10aDiagnostic10aDung beetles10aFaunistics10aScarabaeidae10ataxonomy1 aVaz-de-Mello, Fernando, Z.  uhttps://scarabnet.myspecies.info/estado-atual-do-conhecimento-dos-scarabaeidae-s-str-coleoptera-scarabaeoidea-do-brasil
