Abstract:-The new species Notiobia glabrata, N. maxima and N. pseudolimbipennis are described. A key to the 11 Notiobia (s.str.) species known from Brazil, data about the junior synonym of N. nebrioides Perty, 1830, and Notiobia umbrata Bates, 1882 is a junior different species groups, each distributed from Brazil over the North-Western part of South America, Central America to Mexico.
“…Harpalini is one of the more speciose tribes of Carabidae (Cieglar 2000)and is represented in this collection by 2 genera, Pelmatellus and Notiobia . In the Neotropics, Pelmatellus is a high altitude genus with a body length of < 11mm while Notiobia ’s body length is generally > 10 mm and inhabits lower altitudes (Goulet 1974; and Arndt (1998). The data from this study supports this observation since Notiobia was only found at the 1500 m and 2000 m sites, while Pelmatellus occurred along the entire gradient.…”
Carabid beetles were sampled at five sites, ranging from 1500 m to 3400 m, along a 15 km transect in the cloud forest of Manu National Park, Perú. Seasonal collections during a one year period yielded 77 morphospecies, of which 60% are projected to be undescribed species. There was a significant negative correlation between species richness and altitude, with the number of carabid species declining at the rate of one species for each 100 m increase in altitude. The majority of species (70.1 %) were restricted to only one altitudinal site and no species was found at more than three of the five altitudinal sites. Only one genus, Pelmatellus (Tribe Harpalini), was found at all five sites. Active (hand) collections yielded approximately twice as many species per individuals collected than passive (pitfall trap) collections. This study is the first systematic sampling ofcarabid beetles of a high altitude gradient in the cloud forests of southeastern Perú and supports the need to conserve the zone of extremely high biodiversity present on the eastern slopes of the Peruvian Andes.

“…Eight species are seed feeders and belong to the genus Notiobia. Three of the Notiobia species, formerly unknown to science, N. glabrata, N. maxima, N. pseudolimbipennis, have been described by Arndt (1998).…”

“…Newly hatched adult beetles (teneral) have to migrate from the leached fruit fall site to find a new food source. The two fig seed specialists are of different size (Arndt 1998) and are sympatric on fruit falls. Notiobia flavicinctus is usually less abundant and only about half of the size of the larger species Notiobia pseudolimbipennis.…”
The carabid beetle assemblage found feeding on fig fruit falls at night was studied in a terra firme rain
forest near Manaus (Amazonia) from July 1991 to August 1996. A total of 8926 carabid beetles were collected on 64
fruit falls from 10 fig species. The most abundant genus was Notiobia with eight species, N. pseudolimbipennis being
the most abundant. The Notiobia species comprised 92% of all specimens collected and all feed on small fig seeds.
Their species abundance patterns varied considerably between individual fruit falls and during the course of a single
fruit fall. However, the species abundance patterns for all Notiobia at all observed fruit falls for each of the two
commonest fig species (Ficus subapiculata, F. guianensis), as well as for fruit falls of the remaining fig species, were
very similar. Through feeding and breeding experiments and observations of reproductive success by dissection of
females, only two of the eight Notiobia species were found to be specialized fig seed feeders, being able to reproduce
only on fig fruit falls. The remaining six species of this genus use fig fruit falls as alternate hosts or ‘stepping stones’
between fruit falls of their host trees, which are widely separated both in time and space.
“…Individuals were collected in various field trips between 1987 and 2019. Identifications were made following the taxonomic keys proposed by Arndt (1998), Martínez (2005), Hoover (2016), Erwin and Henry (2017), and Shpeley et al (2017), and by identification/confirmation by specialists in the family: Terry Erwin (Smithsonian Museum of Natural History, Washington, USA), Danny Shpeley (Strickland Museum, University of Alberta, Edmonton, Canada) and Pierre Moret (Université Toulouse II, France). In addition, some records were confirmed by comparison with high quality images of type material deposited in the Natural History Museum (NHM, London, United Kingdom) and the Museum of Zoology of the University of Sao Paulo (MZUSP, São Paulo, Brazil).…”

We report new records of eight species of ground beetles (Coleoptera, Carabidae) from Colombia originated from recent field trips and from museum specimens: Amblygnathus suturalis Putzeys, 1845 (Atlántico), Bembidion chimborazonum Bates, 1891 (Valle del Cauca), Homopterus subcordatus Darlington, 1950 (Caquetá), Hyboptera auxiliadora Erwin, 2004 (Bolívar), Neoaulacoryssus cupripennis (Gory, 1833) (Tolima), Notiobia disparilis Bates, 1878 (Caquetá), Notiobia glabrata Arndt, 1998 (Caquetá), and Trichopselaphus magnificus Ball, 1978 (Valle del Cauca). These records belong to species expected to be found in Colombia, because previous studies have shown their presence in nearby countries, but whose presence in the country was not confirmed so far.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
