“…It coincided with band sequences of C. columbiensis and C. anonymus , as well as those of C. reissi and C. inquinatus Correia et al, 2006. Three inversion steps distinguished it from C. calligraphus (Spies et al 2002).…”

“…Very conservative is the band sequences of arm E -it is not changed in comparison with other American species. Also, groups of bands close to the centromere and telomere regions of arms A, B, C, D, E and F are constant and found in other American species , 2006. Only one step of inversion in arm F distinguished this species from C. anonymus.…”

“…Comparative karyological analysis was done with other American species , Spies et al 20022006). The identification of chromosome banding patterns of the new species follows Keyl (1962) Paratypes: 3 males with pupal and larval exuviae (B1-02, B1-03, B1-04, LEIA/UFSCar), 2 males with pupal exuviae (B1-04, B1-06, LEIA/UFSCar), 4 larvae in two slides (B1-07, B1-08, LEIA/UFSCar), as holotype; 1 male with pupal and larval exuviae (B1-09, LEIA/ UFSCar), 2 larvae in the same slide, (B1-10, LEIA/UFSCar), as holotype except, Lagoa do Infernão, 10/v/1996; 1 male with pupal exuviae, (B1-11, LEIA/UFSCar), as holotype except, São Carlos (21° 59' 10''S, 47° 52' 52'' W), leg.…”

“…The cosmopolitan genus Chironomus Meigen, 1803 comprises several hundred species, some of which are separable only on cytological characters. In Brazil are known until to the present 16 species, including 15 records to São Paulo State 2006;Correia & Trivinho-Strixino, 2007). Some species of this genus are very abundant in heavily polluted standing or running waters; others commonly colonize small water bodies such as fish breeding tanks where they complete their life cycle in a few days.…”

The paper presents a description of larva, pupa, imago (male) and karyotype of Chironomus amissum from southeastern Brazil. It belongs to pseudothummi cytocomplex with 2n=8 and chromosome arm combinations: AE BF CD G. Several fixed homozygous inversions distinguished arm A of the new species from that of Chironomus columbiensis Wülker et al. 1989 and Chironomus anonymus Williston, 1896. One homozygous inversion of arm F differentiated it from C. anonymus. Species-specific characters were presented in the larva, pupa and imago.

“…Spies and Reiss (1996) catalogued 19 species from the Neotropical region. However, this number clearly represents outdated knowledge and signiicantly underestimates the real diversity of Chironomus in the Neotropics, considering that several new species have been described more recently (CORREIA; 2006;. In our study, larvae of Chironomus (see Figure 1a) were found associated with the following freshwater sponges: Corvoheteromeyenia australis (Bonetto; Ezcurra de Drago), Heteromeyenia cristalina Batista, Volkmer-Ribeiro & Melão, Radiospongilla inesi Nicacio & Pinheiro and Tubella variabilis Boneto & Ezcurra de Drago.…”

A região Neotropical possui uma rica fauna de esponjas de água doce, porém o conhecimento sobre sua taxonomia, bem como sobre as comunidades dentro delas permanece fragmentado. Larvas de Chironomidae (Insecta, Diptera) associadas a esponjas de água doce têm sido amplamente relatadas na literatura, com alguns gêneros que são reconhecidos como contendo espécies exclusivamente dependentes desses organismos. Neste estudo, analisamos a ocorrência de larvas de Chironomidae associadas a esponjas de água doce (Spongillidae) no nordeste do Brasil. As amostras foram coletadas em dois sistemas aquáticos em Pernambuco, no período de fevereiro de 2011 a outubro de 2012. No Rio Sirinhaém, Corvoheteromeyenia australis (Bonetto & Ezcurra de Drago) foi a única esponja coletada, sendo que Polypedilum Kieffer, Goeldichironomus Fittkau, Xenochironomus Kieffer e Cricotopus Van der Wulp foram os Chironomidae registrados como representantes dessa fauna associada. Por outro lado, no tanque de piscicultura, Heteromeyenia cristalina Batista, Volkmer-Ribeiro & Melão, Radiospongilla inesi Nicacio & Pinheiro e Tubella variabilis Boneto & Ezcurra de Drago foram as esponjas coletadas, e Polypedilum, Chironomus Meigen, Dicrotendipes Kieffer e Goeldichironomus foram as larvas associadas a essas espécies de esponjas. Embora apenas espécies pertencentes ao gênero Xenochironomus sejam relatadas em estreita interação com esponjas de água doce, aqui documentamos outros gêneros de Chironomidae também associados a esses organismos. No entanto, é necessária uma investigação mais aprofundada para entender melhor como as larvas de Chironomidae usam esponjas como abrigo e/ou prevenção de predação de forma facultativa. O objetivo do presente estudo foi analisar a ocorrência de habitantes de Chironomidae de esponjas de água doce em sistemas aquáticos no estado de Pernambuco, a fim de incrementar o conhecimento de Chironomidae habitantes de esponjas no nordeste do Brasil.

We present data on Chironomidae (Insecta: Diptera) collected in South America together with results on the mitochondrial DNA diversity within selected megadiverse genera. This work is part of an ongoing project on the ancient origin of South American biodiversity using non-biting midges. Collections were made at 42 localities, in March 2014 and February 2015, in a diverse array of habitats, including small streams, rivers, ponds, lakes and bays. In total, 3196 representatives of six subfamilies were collected. Sixty-one genera were identified, containing at least 211 species. The subfamilies Chironominae and Orthocladiinae predominated in all samples. Tanypodinae were often present, but rarely in large numbers. Except for Podonomus pepinellii, reported from Brazil, Podonominae were collected in a few localities in Argentina (Arroyo Lopez, and Arroyo Gutierrez and Gutierrez Lake) and Chile (Llanquihue Lake). Prodiamesinae were only recorded in Chile. Analysis of DNA barcode sequences using neighbor-joining estimation supported 66 species within the selected genera. The chironomid fauna of South America includes multiple genera with worldwide distributions, with Australian, Nearctic and Neotropical components.
