Towards global insect biomonitoring with frugal methods.

None of the global targets for protecting nature are currently met, although humanity is critically dependent on biodiversity. A significant issue is the lack of data for most biodiverse regions of the planet where the use of frugal methods for biomonitoring would be particularly important because the available funding for monitoring is insufficient, especially in low-income countries. We here discuss how three approaches to insect biomonitoring (computer vision, lidar, DNA sequences) could be made more frugal and urge that all biomonitoring techniques should be evaluated for global suitability before becoming the default in high-income countries.

(Sauaia and Alves)-An Overview of a Model Organism in Genetics, with New Aspects in Morphology and Systematics.

(Sauaia & Alves, 1968) is a sciarid that has been continuously cultured in the laboratory for nearly 60 years. Studies on this species have contributed to the understanding of DNA puffs, which are characteristic of Sciaridae, and to the knowledge of more general aspects of insect biology, including cell death, nucleolar organization, and the role of the hormone ecdysone during molting. The genome of has now been sequenced, and it is the third publicly available sciarid genome.

The oldest Gondwanan fossil of Leiinae (Diptera, Mycetophilidae): Phylogenetic and evolutionary implications.

A fossil Mycetophilidae from the Aptian Crato Formation-Cretomanota gondwanica gen. nov., sp.

Atlantic flower-invertebrate interactions: A data set of occurrence and frequency of floral visits.

Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costly and time-consuming, especially in the highly diverse tropics.

Four new Neotropical species of Loew (Diptera, Mycetophilidae, Sciophilinae) from the Colombian high Andean ecosystems, with comments on the genus.

Four new species of the sciophiline genus Loew are described for the Eastern and Central Andes of Colombia- , , and . These are the first species of described from the extreme northern range of the Andes. The altitudinal distribution of these species in the paramos and high Andean forest ecosystems is restricted to 1750-3660 m a.

A total of 286 male specimens of Manota from 38 different collecting sites in the Brazilian Atlantic Forest were analysed. They belong to 32 different species, including 20 described as new to science and 12 recognized as previously described species. The new species are M.

Comprehensive inventory of true flies (Diptera) at a tropical site.

Estimations of tropical insect diversity generally suffer from lack of known groups or faunas against which extrapolations can be made, and have seriously underestimated the diversity of some taxa. Here we report the intensive inventory of a four-hectare tropical cloud forest in Costa Rica for one year, which yielded 4332 species of Diptera, providing the first verifiable basis for diversity of a major group of insects at a single site in the tropics. In total 73 families were present, all of which were studied to the species level, providing potentially complete coverage of all families of the order likely to be present at the site.

Remarkable fly (Diptera) diversity in a patch of Costa Rican cloud forest: Why inventory is a vital science.

Study of all flies (Diptera) collected for one year from a four-hectare (150 x 266 meter) patch of cloud forest at 1,600 meters above sea level at Zurquí de Moravia, San José Province, Costa Rica (hereafter referred to as Zurquí), revealed an astounding 4,332 species. This amounts to more than half the number of named species of flies for all of Central America. Specimens were collected with two Malaise traps running continuously and with a wide array of supplementary collecting methods for three days of each month.

First two species of Austroleptis Hardy (Diptera: Brachycera: Austroleptidae) from Brazil.

Two new species of the genus Austroleptis Hardy, so far known only from Australia and Chile, are described from the Brazilian Atlantic Forest-A. longirostris nov. sp.

New species and new records of Williston from Colombia, Brazilian Amazonia, and Costa Rica (Diptera, Mycetophilidae).

The following five species are described as new: (Colombia), (Colombia), (Costa Rica), (Colombia) and (Colombia). In addition, new records for the following 11 species are presented: Jaschhof & Hippa, 2005 (Costa Rica), Jaschhof & Hippa, 2005 (Costa Rica), Jaschhof & Hippa, 2005 (Costa Rica), Jaschhof & Hippa, 2005 (Costa Rica), Jaschhof & Hippa, 2005 (Colombia, Brazilian Amazonia, Costa Rica), Hippa, Kurina & Sääksjärvi, 2017 (Brazilian Amazonia), Jaschhof & Hippa, 2005 (Costa Rica), Jaschhof & Hippa, 2005 (Colombia, Costa Rica), Hippa & Kurina, 2013 (Brazilian Amazonia), Jaschhof & Hippa, 2005 (Colombia) and Jaschhof & Hippa, 2005 (Costa Rica). Distribution patterns include (1) species known only locally in Costa Rica or Colombia, (2) distributions connecting Central America to west Andes lowlands, and (3) north-west Neotropical components, extending from Central America to Brazilian Amazonia.

The first phylogenetic study of Mesembrinellidae (Diptera: Oestroidea) based on molecular data: clades and congruence with morphological characters.

The Mesembrinellidae (Diptera: Oestroidea) comprise a small group of strictly Neotropical calyptrate flies, with 36 described species. The group has often been treated as a subfamily of Calliphoridae, but there is growing evidence that it corresponds to a distinct Oestroidea lineage. Internal relationships have so far been addressed based only on morphology, with results lacking resolution and support.

Baby Killers: Documentation and Evolution of Scuttle Fly (Diptera: Phoridae) Parasitism of Ant (Hymenoptera: Formicidae) Brood.

Background: Numerous well-documented associations occur among species of scuttle flies (Diptera: Phoridae) and ants (Hymenoptera: Formicidae), but examples of brood parasitism are rare and the mechanisms of parasitism often remain unsubstantiated.

New Information: We present two video-documented examples of ant brood (larvae and pupae) parasitism by scuttle flies. In footage from Estação Biológica de Boracéia in Brazil, adult females of Borgmeier can be seen attacking workers of (Mayr) species group while they are carrying brood, and ovipositing directly onto brood in the nest.

Going beyond the tip of the Drosophilidae iceberg: New Cladochaeta Coquillett, 1900 (Diptera: Drosophilidae) from Brazil.

Drosophilidae comprises more than 4,000 described species worldwide. Despite the huge number of papers published on the genus Drosophila Fallén, 1823, large parts of the family are still poorly known. The drosophiline genus Cladochaeta Coquillet, 1900 has more than 100 Neotropical and several southern Nearctic described species, but there is quite a large number of undescribed species.

Three new species of Calliceratomyia Lane (Diptera: Ditomyiidae) from Neotropical Mexico.

Three new species of the ditomyiid genus Calliceratomyia Lane, so far known only from the type-species from southeastern Brazil, are described from Mexico. The new species-Calliceratomyia papaveroi sp. n.

FAMILY SCATOPSIDAE.

An updated catalogue of the family Scatopsidae in Colombia is presented. Seven species of six genera have being recorded for the country, but four of these species are still undescribed. The Ectaetiinae genus Ectaetia, the Psectrosciarinae genera Anapausis and Psectrosciara, and at least the Scatopsinae genera Scatopse, Efcookella, and Abrhexoza are expected to be present in the fauna of the family in Colombia.

FAMILY MYCETOPHILIDAE.

The Mycetophilidae include small fungus-gnats which life cycle is associated with fungi, especially of the larvae. The known diversity of the family in the Neotropical region is 1,145 species, but only some very few papers have been published on the Colombian species of Mycetophilidae, with records for the genera Docosia Winnertz, Paraleia Tonnoir, and Dziedzickia Johannsen. This catalogue gathers the information available on mycetophilids from Colombia, including genera and some species that for the first time are mentioned to occur in the country-as Leiella unicincta Edwards and Leiella zonalis Edwards.

FAMILY LYGISTORRHINIDAE.

The Lygistorrhinidae are a family belonging to the suborder Bibionomorpha, with no previous record from Colombia. This paper refers for the first time to the occurrence of the family in the country, an undetermined species of the genus Lygistorrhina (Probolaeus) Williston.

FAMILY RANGOMARAMIDAE.

This small family of Diptera is poorly known in Colombia. In the present catalogue, we feature a single report for the country, of a species of the genus Eratomyia.

FAMILY BIBIONIDAE.

The Bibionidae are a family belonging to the suborder Bibionomorpha with four genera and 17 species known from Colombia. This work expands the distribution of these species to other localities in the country.

FAMILY ANISOPODIDAE.

This considerably small family is poorly known in Colombia, with only two species reported for the genus Sylvicola Harris (1776) so far. We synonymize Neomesochria Amorim & Tozoni (1994) to Mycetobia Meigen (1818), hence transferring the Dominican amber species Neomesochria antillea (Grimaldi 1991) and N. cryptambra (Grimaldi 1991), and the recent Neotropical species N.
