Tettigoniidae (Orthoptera: Ensifera) do Parque Nacional do Iguaçu, Brasil: diversidade, bioacústica e descrição de novas espécies

Dissertação apresentada ao Programa de Pós-Graduação em Biodiversidade Neotropical, do Instituto Latino-Americano de Ciências da Vida e da Natureza da Universidade Federal da Integração Latino-Americana, como requisito parcial à obtenção do título de Mestre em Biodiversidade Neotropical. Orientador: Luiz Roberto Ribeiro Faria Junior e Coorientador: Neucir SzinwelskiTettigoniidae é a família mais diversa de Orthoptera, seus representantes ocupam todos os extratos vegetacionais, da serrapilheira ao dossel florestal, e grande parte das espécies são florestais, e utilizam sinais acústico para comunicação. O objetivo deste trabalho foi fazer um inventário faunístico das espécies de Tettigoniidae para o Parque Nacional do Iguaçu, incluindo descrição de espécies novas e descrição da bioacústica das espécies. Para isso coletamos em três cidades que compõe o ParNaIguaçu, Foz do Iguaçu, Serranópolis do Iguaçu e Céu Azul, os indivíduos coletados foram mantidos em laboratório e o som de chamado produzido pelos machos foi registrado com gravador Tascam e AudioMoth em configurações específicas. Registramos 83 táxons, destes 62 identificados em nível de espécie, 11 que correspondem a espécies novas para a ciência e 9 identificados a nível de gênero, que podem vir a corresponder espécies novas para a ciência. A subfamília mais abundante foi Phaneropterinae, com 52 táxons, seguida de Conocephalinae com 22, Pseudophyllinae e Meconematinae com 4 cada e Pterochrozinae com 2. Registramos e descrevemos o som de chamado para 36 táxons de Tettigoniidaae, destes 31 ainda não registrados e formalmente descritos na ciência. Destes sons, oito correspondem a espécies de Conocephalinae, um à Meconematinae, 25 a espécies de Phaneropterinae, três à Pseudophyllinae e um a Pterochrozinae.Tettigoniidae is the most speciose family within Orthoptera, occupying all vegetational strata, from litter to canopy. Most katydids are related to forests, and the production of acoustic signals is paramount to their biology. This work aimed at inventoring the species of Tettigoniidae occurring at the Iguaçu National Park, a large remnant of Atlantic forest in southern Brazil, besides describing new species and the calling songs of collected katydids. Collected specimens were maintained in the laboratory for sound recording in Tascam and AudioMoth devices, using specific configurations. A total of 83 species (62 of them identified in species level), 11 of them corresponding to undescribed species (new to science). The most abundant subfamily was Phaneropterinae (52 taxa), followed by Conocephalinae (22), Pseudophyllinae and Meconematinae (four each), and Pterochrozinae (two species). We were also able to record and describe the calling songs of 36 species, 31 unknown to science until then. Sounds were recorded for species of Phaneropterinae (24), Conocephalinae (8), Pseudophyllinae (3) and Pterochrozinae (1)

A tritrophic interaction at the Brazilian triple frontier: new record of parasitism on Conocephalus saltator (Sausurre, 1859) (Orthoptera, Tettigoniidae)

ABSTRACT We report for the first time a tritrophic relationship (host-parasitoid-hyperparasitoid) among Conocephalus saltator (Sausurre, 1859) (Orthoptera, Tettigoniidae), Ormia cfr. crespoi Tavares, 1965 (Diptera, Tachinidae), and Perilampus sp. (Hymenoptera, Perilampidae). Specimens of C. saltator were collected at the Parque Nacional do Iguaçu (Foz do Iguaçu, Paraná, Brazil) and reared in the laboratory, in order to detect eventual parasitoids. We collected and reared 904 katydids, with 113 of them parasitized, producing 123 fly puparia, and 18 puparia that developed to adults of Ormia cfr. crespoi. We also recorded the emergence of four hyperparasitoid wasps, Perilampus sp., from the fly puparia

Antennal sockets a little dilatated at the curvature near base of the fastigium of the frons and in the apex of the fastigium of the frons. Fastigium of the vertex conical; a little dilatated at apex; with a sulcus on middle reaching apex. <b>Thorax:</b> Pronotum plain colour. Pronotal disc (Fig. 8C) with posterior margin convex; anterior margin concave; furcal sulci bell-shaped; with the same width from anterior to posterior region. Lateral lobes (Fig. 8D) smaller than pronotal disc, longer than wide; anterior margin straight; posterior margin convex and semilunar; humeral sinus presenting an angle of <i>ca.</i> 85º. Tegmina (Fig. 8A; 12B) shorter than hindwings; anal and costal margins parallel; Sc with one bifurcation; R with 12 bifurcations that reaches costal margin; M long, following R in all extension; MA with one apical bifurcation; MP with one bifurcation after half of its length; CuA almost straight, with none bifurcations; stridulatory area of left tegmen with brownish stains, A1 brown (Fig. 8F, G). Mesobasisternum (Fig. 8E) a little elevated on middle; anterior margin almost concave; lateral lobes small, demilune shaped, posterior margins very distant from each other. Metabasisternum (Fig. 8E) triangular; very large; with a straight anterior margin; lateral lobes demilune shaped, not so distant in the posterior margin. <b>Abdomen:</b> Tergite X fused to epiproct; posterior margin projected posteriorly and downwards, depressed on medial region. Cercus (Fig. 8H, I) not very long; bifurcation on apex, giving a shallow cup aspect; the ventral process longer than others, curved upwards and to the middle region; medial process shorter than others, triangular; dorsal process as long as half of ventral process, pointed, ending in a spine, moderately curved to the medial region. Subgenital plate (Fig. 8H, I) very long; triangular shaped; medial region depressed; posterior processes long, curved upwards and to the medial region, touching in apex. <i>Genitalia</i> (Fig. 8J, K): Phallus symmetrical with exception to titillator’s sclerites, rounded, membranous but with two titillator sclerites that is quite big and curves in a U form; and titillator’s tips exposed and more sclerotized.</p> <p> <b>Type Material:</b> <i>Holotype male</i>, ‘ DPTO ZOOL \ UF –PARANÁ’ ‘Cáceres, MT. \ 14.XI.1984 \ Buzzi, Mielke, Elias \ Casagrande leg. \\ PROJ.

This new species confirms the proximity of Furcata and Juanchoi species group, and its positioning in the <i>A.</i> (<i>Oecella</i>), when the subgenera was described, by Gorochov (2020), the author comments that the Juanchoi species groups possibly belongs to the aforementioned subgenus. Additionally, this species gives clues that the Furcata and Juanchoi species group are indeed related. From the Juanchoi species group, <i>A.</i> (<i>O.</i>) <i>mediastina</i> <b>sp. n.</b> is closely related to <i>A.</i> (<i>O</i>.) <i>zebrina</i> <b>sp. n.</b>, since the apex of male cerci presents three processes, and have a cup-like aspect. From the Furcata species group the closest relative is <i>A.</i> (<i>O.</i>) <i>darwinii</i> Scudder, specially for the thickness of the cerci. Besides being placed in any group of <i>A.</i> (<i>Oecella</i>), the <i>A. mediastina</i> <b>sp. n.</b> is more related to the aforementioned species groups of the subgenera than the ungrouped species of the subgenera (<i>A.</i> (<i>O</i>.) <i>confusa</i>, <i>A.</i> (<i>O</i>.) <i>lingulata</i>, <i>A.</i> (<i>O</i>.) <i>mediastina</i>, and <i>A.</i> (<i>O</i>.) <i>marshae</i> <b>sp. n.</b>)</p>Published as part of <i>Fianco, Marcos, 2021, Nine new species of the Anaulacomerina subtribe of katydids (Orthoptera Tettigoniidae: Phaneropterinae: Phaneropterini) from Brazil, pp. 33-54 in Zootaxa 4952 (1)</i> on pages 45-47, DOI: 10.11646/zootaxa.4952.1.2, <a href="http://zenodo.org/record/4671657">http://zenodo.org/record/4671657</a&gt
