Distribution and Abundance of Necrophagous Flies (Diptera: Calliphoridae and Sarcophagidae) in Maranhão, Northeastern Brazil

This study aimed at surveying the local calliphorid and sarcophagid species in Maranhão State (Brazil) to determine their distribution and abundance, as well as the distribution of exotic Chrysomya species. In total, 18,128 calliphorid specimens were collected, distributed in 7 genera and 14 species. The species Hemilucilia semidiaphana (Rondani, 1850) and Paralucilia paraensis (Mello, 1969) were new state records. Chrysomya albiceps (Wiedemann, 1819) and Cochliomyia macellaria (F., 1775) were the most abundant species, and the exotic species of Chrysomya together contributed more than 50% of total blow fly abundance. The abundance distribution of the calliphorid community conformed to a log series model, characterized by a steep curve that reflects an assemblage with a high degree of dominance. For the Sarcophagidae, a total of 14,810 specimens were collected and distributed in 15 genera, 11 subgenera, and 52 species. Tricharaea (Sarcophagula) occidua (F., 1794) and Peckia (Sarcodexia) lambens (Wiedemann, 1830) were the most abundant species. The abundance distribution of the species followed a log normal model, with a gentler slope, consistent with a more uniform community. The cumulative species curve for the sarcophagids did not reach the asymptote. Forty-three sarcophagid species were new state records and 22 were new records for the Brazilian northeast, which emphasizes the need for a continued survey in this region.

A further new species of Sarcofahrtiopsis Hall (Diptera: Sarcophagidae) associated with faeces of the disk-winged bat ( Thyroptera Spix: Chiroptera) in Brazil and the redescription of the female terminalia of S. cuneata (Townsend)

The male, female and puparium are described for Sarcofahrtiopsis cupendipe sp. nov., whose larvae live in the roosts of disk-winged bats (Thyroptera species). Sarcofahrtiopsis cupendipe and S. thyropteronthos Pape, Dechmann & Vonhof are both associated with the faeces of the disk-winged bat and are the only species of Sarcofahrtiopsis with wing vein R1 fully setose dorsally and a short parameral apodeme in the male terminalia. In addition, the female terminalia of S. cuneata (Townsend) is redescribed.

A new species of Japanagromyza Sasakawa (Diptera: Agromyzidae) from the Brazilian Amazon with notes on biology.

Japanagromyza sasakawai sp. n. is described from the Brazilian Amazon, based on the male, female, third instar larva and puparium. This species is a leaf-miner of Terminalia catappa L. (Combretaceae), which is an introduced plant from the Old World tropics used in Brazil as an ornamental. The male aedeagus of J. sasakawai sp. n. differs from other species mainly in having the mesophallus covered with many spine-like processes. This is the third record of Japanagromyza Sasakawa in Brazil and first in the Brazilian Amazon. The key to Neotropical species of Japanagromyza by Sousa & Couri (2014) is modified to include this new species.

Observations on the nesting behaviour of the spider wasp Eragenia congrua (Hymenoptera: Pompilidae), with the first record of the host

We describe, for the first time, the nesting behaviour of an Eragenia spider wasp, Eragenia congrua, based on field observations in the Brazilian Amazon. This species was observed nesting in holes at the base of the trunk of a Jacaranda copaia tree and provisioning nests with both amputated and non-amputated species of undetermined Corinna sp. (Corinnidae) spiders. The spiders are carried forward and grasped at the base of the chelicerae. Nesting is gregarious with females nesting in the same small area on successive days.

A new species of Sarcofahrtiopsis (Insecta, Diptera, Sarcophagidae) from mangrove forests in the Brazilian Amazon, with a key to species identification

A new species of Sarcofahrtiopsis Hall, 1933, S. terezinhae sp. nov., is described based on male specimens collected in traps baited with rotting crabs in a mangrove forest in the state of Pará, eastern Brazilian Amazon. This species differs from congeneric species in having vesica with a row of toe-like projections. We provide a key to the species of the genus.

Description of a nomen nudum species of Liriomyza Mik and the first record of Liriomyza blechi Spencer from Brazil (Insecta: Diptera: Agromyzidae)

The nomen nudum Liriomyza flagellae is formerly described in this paper as Liriomyza valladaresae sp. nov., based on male and female specimens collected in the Brazilian Amazon and reared from leaves of Alternanthera tenella and Amaranthus viridis (Amaranthaceae). Information on the puparium and the biology of this new species are provided. The species Liriomyza blechi, previously recorded from the U.S.A., Guadeloupe and Dominican Republic, is newly recorded from Brazil, reared from leaves of Blechum pyramidatum (Acanthaceae) and Spigelia anthelmia (Loganiaceae).

Description of new species of Surimyia Reemer and Carreramyia Doesburg (Diptera: Syrphidae) from the Brazilian Amazon

Surimyia reemeri sp. n. and Carreramyia jatai sp. n. are described from the Brazilian Amazon. The diagnosis of Surimyia Reemer is emended to include S. reemeri sp. n. that differs from other species of the genus mainly by the shape of male terminalia and basoflagellomere length. In addition, S. rolanderi Reemer is recorded for Brazil for the first time. The key to species of Carreramyia Doesburg by Reemer (2008) is modified to include C. jatai sp. n., and a key to species of Surimyia is provided.
