Tetramereia convexa (Harold, 1869) (Coleoptera: Scarabaeidae: Scarabaeinae) is reported for the first timefrom Loreto in Peru, being the western most record of the species in South America.Key words. New record, Scarabaeinae, Peru.Resumen. Tetramereia convexa (Harold, 1869) (Coleoptera: Scarabaeidae: Scarabaeinae) es reportado por primeravez para Loreto en Perú, siendo el registro más occidental de la especie para Sur America.Palabras claves. Nuevo registro, Scarabaeinae, Perú.IntroductionThe dung beetles of the subfamily Scarabaeinae contains about 6000 species and 234 genera world-wide (Scarabnet 2009). Much of this fauna is distributed in the tropics with 1300 species and about 70genera (Halffter 1991). Many dung beetles live on the fecal material of other animals and benefit theenvironment by recycling nutrients, moving and burying seeds of various plants, and serving as biologi-cal control agents of gastrointestinal nematodes and fly larvae that use this dung as a resource (Nicholset al. 2008). As these insects require dung from vertebrates, habitat alterations that result in vertebratepopulation changes may also affect the local diversity (Nichols et al. 2009, Quintero and Halffter 2009).In addition, dung-burying species provide a suite of critical ecosystem functions and services, yet theyface multiple conservation threats, particularly from landscape conversion (Slade et al. 2011). Dungbeetle assemblages responded to a variety of anthropogenic disturbances in tropical forests and supporttheir utility as focal taxa (Nichols et al. 2007).Scarabaeinae are also used as focal taxa in biological characterizations, rapid ecological assess-ments, and biodiversity monitoring to estimate alpha and beta diversity (Halffter and Favila 1993, Favilaand Halffter 1997, McGeogh et al. 2002). This kind of research has generated databases to facilitateanalysis and interpretation of biodiversity (Villarreal et al. 2004). However, in some specific genera theavailable information is scarce especially in the tribe Phanaeini where some particular taxa such asDendropaemon Perty, Gromphas Brullé, Homalotarsus Janssens, Megatharsis Waterhouse, OruscatusBates and Tetramereia Klages are not well known in their habits or in their geographical distribution(Edmonds 1972).This is the case of the dung beetle Tetramereia convexa (Harold, 1869) that is widely distributed incentral-southern Brazil (“cerrado”), also known from the Distrito Federal and from the states of MinasGerais, Pará, and São Paulo (Noriega et al. 2008). Arnaud (2002) reported the species, from Brazil(Pará), Venezuela (Suapure, State of Bolivar), and French Guiana, but he provided no precise data ornumber of specimens studied. Klages (1907) initially discover the species in the Cuara River valley in2 • INSECTA MUNDI 0270, December 2012 AMPUDIA GATTY ET AL.Venezuela. The report of T. convexa in Colombiasuggests a wider distribution pattern more locatedin the Orinoquía zone than in the Amazon (Noriegaet al. 2008).This species has been collected in nests of theant genus Atta Fabricius (Vaz-de-Mello et al. 1998),and adults of T. convexa have been maintained incaptivity with ant detritus. However, very little isknown about the natural history of T. convexaand other related genera of the Phanaeini tribe(Dendropaemon Perty, Homalotarsus Janssens,and Megatharsis Waterhouse,). It is possible, assome authors have proposed (Vaz-de-Mello et al.1998; Philips et al. 2004), that these genera forma monophyletic myrmecophilous group and thattheir supposed rarity is a result of narrow eco-logical specialization and sampling bias.DiscussionDuring a sampling project in four kinds ofunderstudied forests in the Loreto region of Peru,an individual (1 female) of T. convexa (Fig. 1) wascollected using a pitfall trap baited with humanfeces. This is the first record of this species in Peru(Fig. 2). Collection data: PERU. Iquitos: 28 kmIquitos-Nauta road, San Juan Bautista district,Maynas province, Loreto region, AllpahuayoMishana National Reserve (S 3o58’21.80” - W73o25’29.12”), 148 m, Dec. 2010; to southwest of Iquitos city, between Nanay River to northwest andIquitos-Nauta Road to south. The specimen is deposited in the Ampudia and Estrella reference collection.The Allpahuayo Mishana National Reserve has areas with white sand forests commonly known as“varillales”. These forests are fragile habitats rich in endemic and rare species of birds (e.g. Polioptilaclementsi Whitney and Alvarez, Zimmerius villarejoi Alvarez and Whitney, and Percnostola arenarumIsler et al.). The biodiversity of these forests are just beginning to be investigated (Alvarez 2006). Thehabitat where the specimen of T. convexa was collected corresponds to a high, wet, white-sand forest“varillal” (García et al. 2003).The existing and new geographical records (Fig. 2) suggest that the genus T. convexa does not havea relictual distribution, being found in some specific regions but in a wide range in South America (fivecountries: Colombia, Venezuela, French Guiana, Brazil and Peru). In addition, it is important to pointout that the records in Colombia, Venezuela, Peru and the majority of the records in Brazil are not intropical rain forests; most of them are peripheral to the Amazonian region in particular ecosystems likewhite-sand forest, savanna or “cerrado” (Noriega et al. 2008). With an increase in the sampling efforts inthese regions, and specially searching in ant nests (Atta spp.) as some authors suggest (Vaz-de-Mello etal. 1998) it is possible that it can be recorded in other countries like Bolivia, Guyana, Suriname and alsoParaguay.It is necessary to carefully compare specimens from these widely disjunctive regions to determine ifthe populations represent distinct lineages (thus, possibly distinct species or subspecies). Likewise, it isnecessary to continue studying the natural history of these little-known genera with special habits, aswell as to continue survey work in South America where new records may be expected.Figure 1.
