“…5). Among the Neotropical Tanytarsus, a similar anal point is known in T. fastigatus Reiss, 1972 (but broader Paggi, 1992 (triangular at tip), T. sanseverinoi Dantas, Amat, Hamada et Giłka, 2022 (nearly identical with T. pinedoi), T. tuberculatus Reiss, 1972 (with vestigial crests or flap-like enlargements), and in species of the impar group (but shorter, broader or with narrow crest) (Reiss 1972, Paggi 1992, Trivinho-Strixino & Strixino 2004, Trivinho-Strixino & Sonoda 2006, Trivinho-Strixino et al 2015, Dantas & Giłka 2017, Dantas et al 2022. The simple (bare) and slender anal point, but with round apex, we also describe in other new species here (see T. kaxinawa).…”

This research is focused on the diversity and systematics of Neotropical non-biting midges of the genus Tanytarsus van der Wulp, 1874, based on specimens collected from pristine areas of the western Amazon region in Peru and Brazil. Six new species are described: Tanytarsus aries sp. nov. (Peru), T. chicomendesi sp. nov. (Brazil, Acre), T. kaxinawa sp. nov. (Brazil, Acre; Peru), T. pinedoi sp. nov. (Peru), T. serra sp. nov. (Peru), and T. frameatus sp. nov. (Peru), the latter placed in the Tanytarsus hastatus species group, here defined. Data on several recently described Neotropical Tanytarsus, obtained by analyzing specimens recorded from different regions of Brazil (Amazonas, Bahia, Federal District, Pará, São Paulo, Tocantins) are appended, and remarks on the taxonomy and variations of their diagnostic structures are provided. Tanytarsus pollicis Reis, Lin et Ferreira-Keppler, 2022 is treated as a new synonym of Tanytarsus insolens Dantas et Giłka, 2017. Further two species, Tanytarsus marianae Reis, Lin et Ferreira-Keppler, 2022 and Tanytarsus rafaeli Reis, Lin et Ferreira-Keppler, 2022 are placed in the Tanytarsus kiche group. The Tanytarsus curvicristatus group is also supplemented with Tanytarsus giovannii Sanseverino et Trivinho-Strixino, 2010.

“…Chironomidae are the most representative of aquatic insects as a result of the range of habitat occupancy; the use of various resources, which confers adaptive strategies to colonize different types of micro-habitats by different genera of the family (Trivinho- Strixino & Sonada, 2006). This wide range of occurrence in terms of Chironomidae can be explained by their diversified eating habits (Armitage et al, 1995).…”

The objective of this research was to validate the colonization process on natural and artificial substrates by benthic invertebrates in a tropical stream in South Brazil. The samples were performed in July and August-2012, and 32 samplers were used, being 16 natural and 16 artificial substrates. In each sample, two replicas were taken for each substrate at the 2th, 4th, 7th, 14th, 21th 28th, 35th and 42th days of colonization. The organisms were identified to the lowest possible taxonomic level. In both substrates 3,070 benthic invertebrates were detected, of which 1,753 individuals were collected on the natural substrate, and 1,317 on the artificial substrate. From the identified taxa 8.5% were not dominant (Anacroneuria, Orthocladiinae, Tupiara, Smicridea, Baetodes, Tupiperla, Macrogynoplax, Gripopteryx, Cylloepus, Macrelmis, Microcylloepus, Hetaerina, Argia, Coryphaeschna, Atopsyche, Pomacea, Corydalus, Leptohyphes and Eccoptura), and 31.5% were dominant (Tanypodinae, Chironominae, and Paragripopteryx). The genus Simulium was very common, dominant and abundant, representing 65% of the collected individuals. No significant difference was found in the abundance and species composition between artificial and natural substrates. On the natural substrate, the higher colonization index was at the 35th day with 459 individuals, and the lowest was at the 14th day, with 87. On the artificial substrate the highest index was at the 42th day with 337 individuals, and the lowest was at the 4th day, with 85. Both natural and artificial substrates are efficient in characterizing the benthic community. In the evaluation of the ecological succession, it was not possible to observe a pattern that described the process, since the composition was nearly constant throughout the study period.

“…The gonapophysis VIII is divided as in Micropsectra Kieffer and related genera, while all genera of the Zavreliina of which the female genitalia are known as well as in all Tanytarsus van der Wulp and related genera the gonapophysis VIII is undivided. [Trivinho Strixino and Sonoda (2006), however, mention that gonapophysis VIII in Tanytarsus obiriciae is slightly divided, but their drawing contradicts this]. Saether & Roque (2004) did a parsimony analysis of the tribe Tanytarsini.…”

Nandeva digitifer sp. n. from Chile is described and figured as male and female and N. verruculata sp. n. from Brazil as male. The female of N. latiloba Sæther et Roque is also described and figured and new Neotropical records of N. latiloba, N. strixinorum Sæther et Roque and N. tropica Wiedenbrug, Reiss et Fittkau are given. The female of N. fittkaui Cranston is re-examined. New generic diagnosis and description are given for the imagines. Some character states from previous parsimony analyses are corrected and new analyses performed indicating Nandeva as part of Tanytarsini or as part of the sister group to Tanytarsini.
