- Abstract
Background We report the genus Ticapimpla Gauld, 1991 from French Guiana and the species Ticapimpla amazonica Palacio et al., T. carinata Palacio et al., T. matamatae Palacio et al. and T. soinii Palacio et al. from Brazilian Amazonia. The new discoveries suggest that the genus is widely distributed in Amazonian lowland rain forests. In addition, we diagnose and illustrate the males of T. carinata and T. matamatae for the first time. Short diagnoses and layer-photos for all the Amazonian species are provided. New information The genus Ticapimpla is reported for the first time from French Guiana and the species T. amazonica, T. carinata, T. matamatae and T. soinii from Brazilian Amazonia. In addition, the males of T. carinata and T. matamatae are diagnosed and illustrated for the first time. © Pádua D et al.

BIOLOGICAL classification ,SPECIES - Abstract
The omission of critical data in the pursuit of "revolutionary" methods to accelerate the description of species However, the latter authors failed to diagnose their 15 new I Zelomorpha i Ashmead, 1900 species from 51 out of 52 previously known species (only the type species was used in the analysis) and their three new I Hemichoma i Enderlein, 1920 species from any of the five previously known species. (2004) proposed to recognize ten species of skipper butterflies (genus I Astraptes i ) based on DNA characters and ecology and some morphological characters, but the species were not formally named until Brower (2010) described them based exclusively on unique mutations in the DNA barcode region. DNA barcoding is a rapid means to sort specimens into clusters, identify species and discover new ones (when a library of the relevant named species is already available), but does not overcome the bottleneck of the description process itself.

Triclistus amazopeikkus sp. nov. (Figs 1 A–B, 2 A–F, 3 A–E) Diagnosis. The species is easily identified as Triclistus by the specialized form of the subgenital plate which is modified to support the thin ovipositor (Fig. 3 E). In addition, the species is dark colored (Figs 1 A–B) whereas most Colpotrochia Holmgren / Cubus Townes are mostly orange and black in coloration. Triclistus amazopeikkus sp. nov. can be easily distinguished from all other species of the genus by its extremely specialised face which is centrally projecting and forming an extraordinary sub-pyramidal prominence, ending anteriorly with two apical points (Figs 1 B, 2 B–C). These in turn arise from lamellae, which are separated by vertical grooves from the antennal sockets (Fig. 2 B). Description. Female: Body size, 4.9–5.4 mm. Fore wing length 3.2–3.6 mm. Head: antennae with 20 flagellomeres, gradually narrowed towards the apex (Figs 1 A, 1 B), first, second and subapical flagellomeres 5.0– 5.3, 1.4 and 2.0 × as long as centrally broad, respectively; combined face and clypeus 1.0– 1.1 × as long (from clypeal apex to level of antennal sockets) as wide (shortest distance between eyes) (Fig. 2 D); face centrally projecting, forming an extraordinary sub-pyramidal prominence (Fig. 2 A–C), ending apically with two points which arise from lamella and both vertical grooves separating it from antennal sockets (Fig. 2 B), shiny very densely and coarsely punctate at the prominence, gradually sparse ventrally (Fig. 2 C); prominence with strong longitudinal striae ventrally (Fig. 2 E); clypeus smooth and shiny, clypeal margin concave (Fig. 2 C); labrum exposed when mandibles closed (Fig. 2 C), 2.3–2.5 × as wide as long, shiny, with few sparse setiferous puctures, apical rim somewhat bilobed; mandible strongly tapered, somewhat bent upward at the apex, with upper tooth conspicuously longer than lower tooth; malar space 1.0– 1.2 × as long as basal mandibular width; lateral ocellus separated from compound eye by 1.5–1.7 × maximum ocellar diameter; distance between posterior ocelli about 1.0 × maximum ocellar diameter (Fig. 2 B); head in dorsal view with gena slightly rounded and moderately constricted behind eyes (Fig. 2 B); gena, on lateral view 0.7–0.8 × as long as compound eyes, upper part mostly smooth and shiny, sparsely punctate behind ocelli, lateral part smooth and shiny, with a line of 5–6 brown small sensillae close and parallel to the posterior margin of eye, posteriorly with a group of 6–7 sensillae (Fig. 2 F, arrows); lower part gradually densely punctate (Fig. 2 C); vertex quite prominent, coarsely and densely punctate in interocellar space (Fig 2 A–B); frons coarsely and densely punctate, very leaning forward and confluent with the dorsal part of the facial subpiramidal prominence, crest between antennal toruli wide, laterally with two deep grooves to house the antennae when directed backwards (Fig. 2 B). Mesosoma: pronotum shiny, very densely punctate on upper medial and lateral part, setae long; femoral concavities smooth and hairless; mesoscutum flat, coarsely and densely punctate (Fig. 1 A); notauli extending beyond centre, very weak (Fig. 1 B); scuto-scutellar groove deep and smooth; scutellum slightly convex, almost flat, with longitudinal lateral carinae reaching to about 0.4 × its length (Fig. 1 B); mesopleurum smooth and shiny, densely punctate anteriorly, impunctate posteriorly (Figs 1 A, 3 A); mesosternal region with a flattened subtriangular process projecting backwards over the basis of the mid coxa (Fig. 3 A); metapleuron smooth and shiny, with isolated setae in anterior and posterior area, posterior upper corner forming a right angle (Fig. 3 A); submetapleural carina smooth, anteriorly expanded into a conspicuous triangular lobe (Fig. 3 A). Propodeum quite long and slightly convex, weakly declivitous and abruptly down-turned posteriorly with longitudinal carinae strong; confluent area basalis and area superomedia smooth and shiny, hairless (Fig. 3 B), confluent area externa and dentipara smooth and shiny with fine and sparse setiferous punctures (Fig. 3 B), confluent area spiracularis and area lateralis slightly rugulose-granulate, with very dense white pubescence (Fig. 3 A); posterior transverse carina strong; area peciolaris and area posteroexterna confluent, slightly rugulose-granulate with white pubescence; area coxalis forming a deep concavity with white setae (Fig. 3 A); spiracle elongate (Fig. 3 A). Front leg with tibial spur stout and claw-like (Fig. 3 C, arrow); mid leg with anterior tibial spur 0.8–0.9 x length posterior spur, not specialized; hind leg with anterior spur short and stout about 0.5 × length of posterior spur, both spurs strongly sclerotized apically, claw-like (Fig. 3 D); distal hind tarsomere without apparent hooked lobe on the inner side. Fore wing with vein 3 rs-m absent. Metasoma: tergite I smooth and shiny, with fine and very sparse setiferous puctures laterally, 1.45 × as long as posteriorly broad, lateral longitudinal carinae reaching to spiracle, lateromedian carinae extending 0.5 × length of tergite (Fig. 3 B); tergite II smooth and shiny, with very fine and moderately dense setiferous punctures, denser laterally, about 0.92 × as long as posteriorly broad; rest of tergites with same microsculpture but punctures somewhat denser in last ones; subgenital plate with hind margin modified into deeply V-shaped concavity centrally (Fig. 3 E). Colouration (Figs 1 A–B). Black. Antennae, central part of mandibles front and mid legs, and hind tibia basally yellow; hind coxa and femur, and distal apex of front and hind tibial spurs, dark brown; hind trochanters, distal part of hind tibia, hind tarsi, labrum and base of mandibles light brown; maxillae and labium entirely white. Male. Unknown Etymology. We are pleased to name the species as “ amazopeikkus ” which is a combination of names suggested by the children studying in the Kuparivuori School (class 4 B), Naantali, Finland. The word “ amazo ” refers to Amazonia and the word “ peikkus ” is derived from the Finnish word “Peikko” (Peikko is a troll in Finnish). The name “ amazopeikkus ” means “the troll of Amazonia”. In our opinion, it describes well the extraordinary morphology and unknown habits of this species. Material examined. Holotype female: Peru, Department of Loreto, National Reserve of Allpahuayo- Mishana, Malaise trap E 1 (12), 14.IX. 2000, Ilari E. Sääksjärvi et al. leg. (UNSM). Paratype female: Peru, Department of Loreto, National Reserve of Allpahuayo-Mishana, Malaise trap C 1, VIII–XII. 1998, Ilari E. Sääksjärvi et al. leg. (ZMUT).

Ticks (Acari: Ixodoidea) are among the most common vectors of zoonotic pathogens worldwide. While research on tick-borne pathogens is abundant, few studies have thoroughly investigated small-scale spatial differences in their occurrence. Here, we used long-term cloth-dragging data of Ixodes ricinus and its associated, known and putative pathogens (Borrelia burgdorferi s.l., Borrelia miyamotoi, Anaplasma phagocytophilum, Rickettsia spp., Candidatus Neoehrlichia mikurensis, Bartonella spp., Babesia spp., and tick-borne encephalitis virus, TBEV) from a small, well-studied island in southwestern Finland to analyze potential temporal and spatial differences in pathogen prevalence and diversity between and within different biotopes. We found robust evidence indicating significant dissimilarities in B. burgdorferi s.l., A. phagocytophilum, Rickettsia, and Ca. N. mikurensis prevalence, even between proximal study areas on the island. Moreover, during the 6 years of the ongoing study, we witnessed the possible emergence of TBEV and Ca. N. mikurensis on the island. Finally, the stable occurrence of a protozoan pathogen that has not been previously reported in Finland, Babesia venatorum, was observed on the island. Our study underlines the importance of detailed, long-term tick surveys for public health. We propose that by more precisely identifying different environmental factors associated with the emergence and upkeep of enzootic pathogen populations through rigorous longitudinal surveys, we may be able to create more accurate models for both current and future pathogen distributions.

Acrotaphus ,Vespa parasitoide - Abstract
O grupo de gêneros Polysphincta é um clado dentro da tribo Ephialtini (Ichneumonidae, Pimplinae) cujas vespas parasitoides utilizam adultos e sub-adultos de aranhas construtoras de teia orbiculares como hospedeiros. A filogenia mais recente do grupo, utilizando dados morfológicos, havia dividido o grupo em sete clados, sendo o clado F composto pelos gêneros ‘Polysphincta’ + (Ticapimpla + (Hymenoepimecis + Acrotaphus)), ou seja, Polysphincta parafilético e Ticapimpla, Hymenoepimecis e Acrotaphus monofiléticos. O objetivo aqui foi estudar a taxonomia dos gêneros do clado F a fim de organizar e contribuir com estudos futuros dos Pimplinae neotropicais. Para isso, a tese foi dividida em cinco partes: 1) A revisão taxonômica do gênero Acrotaphus Townes. Foram descritas 16 novas espécies (A. amajari sp. n., A. amazonicus sp. n., A. bodoquenaensis sp. n., A. cuzconus sp. n., A. dolichopus sp. n., A. homeofranklini sp. n., A. jackiechani sp. n., A. kourou sp. n., A. micrus sp. n., A. monotaenius sp. n., A. nambilloensis sp. n., A. pseudoamazonicus sp. n., A. pseudomexicanus sp. n., A. sobczaki sp. n., A. venezuelanus sp. n. e A. zampieronae sp. n.). Em adição, A. mexicanus (Cameron) foi redescrita, novos caracteres foram adicionados, no qual foi realizado a descrição da genitália do macho pela primeira vez. Além disso, foi providenciado uma chave de identificação, diagnoses e imagens digitais para todas as espécies do gênero. 2) Uma análise cladística do gênero Acrotaphus Townes foi realizada usando 46 caracteres morfológicos e 35 táxons terminais (nove no grupo externo e 26 no grupo interno). Acrotaphus foi corroborado como monofilético (Zaglyptus + (Polysphincta + (Ticapimpla + (Hymenoepimecis + Acrotaphus)))), tendo como grupo irmão o gênero Hymenoepimecis Viereck. Além disso, a topologia interna do gênero foi proposta pela primeira vez, resultando em oito clados, com o maior número de espécies em seus ramos terminais nos clados G e H. Em adição, foram adicionados e testados pela primeira vez caracteres da cápsula genital dos machos. 3) O grupo de espécies Polysphincta dizardi Gauld foi revisado. Seis espécies novas foram descritas: P. cosnipata sp. n., P. inca sp. n., P. macroepomia sp. n., P. organensis sp. n., P. pichincha sp. n. e P. teresa sp. n.. Em adição, foram providenciadas diagnoses, chave taxonômica e imagens digitais para todas as espécies. 4) Um estudo taxonômico do gênero Hymenoepimecis Viereck do Equador, Guiana Francesa, Nicarágua e Peru foi realizado. Sete novas espécies foram descritas: H. andina sp. n., H. castilloi sp. n., H. dolichocarinata sp. n., H. ecuatoriana sp. n., H. longilobus sp. n., H. pucallpina sp. n. e H. rafaeli sp. n.. Em adição, novos registros geográficos, imagens digitais e uma chave de identificação para todas as espécies do gênero foram providenciadas. 5) O estudo taxonômico do gênero Ticapimpla Gauld foi realizado. Os machos de T. carinata e T. matamatae foram descritos e registrados pela primeira vez para a Guiana Francesa, como também foram registradas, pela primeira vez, as espécies T. amazonica, T. carinata, T. matamatae e T. soinii para o Brasil. Em adição, foram adicionadas diagnoses e imagens digitais dessas espécies. The Polysphincta genus-group is a clade within the tribe Ephialtini (Ichneumonidae, Pimplinae) characterized by parasitoid wasps that utilize adult and sub-adult spiders as host. The most recent phylogeny of the group, using morphological data, divided the group into seven clades, the clade F consisting of ‘Polysphincta’ + (Ticapimpla + (Hymenoepimecis + Acrotaphus)), being Polysphincta paraphiletic and Ticapimpla, Hymenoepimecis and Acrotaphus monophyletic. This study aimed to study the taxonomy of genera of clade F in order to organized and contribute to future studies of neotropical Pimplinae. For this the thesis was divided in five parts: 1) the genus Acrotaphus Townes was reviewed. Sixteen new species were described (A. amajari sp. n., A. amazonicus sp. n., A. bodoquenaensis sp. n., A. cuzconus sp. n., A. dolichopus sp. n., A. homeofranklini sp. n., A. jackiechani sp. n., A. kourou sp. n., A. micrus sp. n., A. monotaenius sp. n., A. nambilloensis sp. n., A. pseudoamazonicus sp. n., A. pseudomexicanus sp. n., A. sobczaki sp. n., A. venezuelanus sp. n. and A. zampieronae sp. n.). In addition, A. mexicanus (Cameron) was redescribed, new characters were added, such as the description of the male’s genitalia for the first time. Also, an identification key, diagnoses and digital images for all species of the genus were provided. 2) A cladistic analysis of genus Acrotaphus Townes was performed using 46 morphological characteres and 35 terminal taxa (nine outgroup and 26 ingroup). Acrotaphus was corroborated as monophyletic, having your sister group the genus Hymenoepimecis Viereck (Zaglyptus + (Polysphincta + (Ticapimpla + (Hymenoepimecis + Acrotaphus)))). Besides, the internal topology of the genus was here first proposed, resulting in eight clades, with the largest number of species in its terminal branches in the clades G and H. In addition, characters from the male genital capsule were added and tested for the first time. 3) Polysphincta dizardi Gauld species-group was reviewed. Six new species were described: P. cosnipata sp. n., P. inca sp. n., P. macroepomia sp. n., P. organensis sp. n., P. pichincha sp. n. and P. teresa sp. n.. Also, diagnosis, taxonomic key and digital images for all species were provided. 4) A taxonomic study of genus Hymenoepimecis Viereck from Ecuador, French Guiana, Nicaragua and Peru was realized. Seven new species were described: H. andina sp. n., H. castilloi sp. n., H. dolichocarinata sp. n., H. ecuatoriana sp. n., H. longilobus sp. n., H. pucallpina sp. n. and H. rafaeli sp. n.. Besides, new geographical records, digital images and an identification key for all species of genus were provided. 5) A taxonomic study of genus Ticapimpla Gauld was realized. The males T. carinata Palacio et al. and T. matamatae Palacio et al. were associated and described, the genus was recorded for the first time to French Guiana, the species T. amazonica Palacio et al., T. carinata, T. matamatae and T. soinii Palacio et al. were recorded for the first time to Brazil. Besides, diagnosis and digital images of these species were added.

- Abstract
Background: Dolichomitus Smith, 1877 is a genus of Darwin wasps characterised by their large bodies and long ovipositors, that includes more than 75 species worldwide, 20 of which occur in the Neotropical Region. Due to recent efforts, the number of species of this genus continues to increase in South America., New Information: A new iridescent species of Pimplinae, Dolichomitus meii sp. nov., is described and illustrated. It was discovered from the biological station of Yanayacu located in the north-eastern slopes of the tropical Andes. It may be separated from all other species of Dolichomitus Smith by the striking colour pattern and apically strongly decurved ovipositor., (Filippo Di Giovanni, Diego Galvão Pádua, Rodrigo Oliveira Araujo, Alvaro Doria Santos, Ilari Eerikki Sääksjärvi.)
