Abstract: Despite an increase in studies involving lycophytes and ferns in recent years, Maranhão is still one of the northeastern states with a poorly known flora, mainly due to low sampling. For Chapada das Mesas National Park, a protected conservation unit in the Cerrado maranhense with phytophysiognomies that favor floristic diversity, there are no floristic studies about lycophytes. This study aimed to conduct the floristic inventory and taxonomic study of lycophytes in Chapada das Mesas National Park. Three collection expeditions, of three days each, were made between March 2017 and June 2018. Three families of lycophytes represented by three genera and six species were identified in the study area. The most diverse family was Selaginellaceae with four species: Selaginella conduplicata, S. erythropus (Mart.) Spring, S. radiata (Aubl.) Baker and S. simplex Baker. The other two families, Isoëtaceae and Lycopodiaceae, had one species each, Isoëtes sp. and Palhinhaea cernua (L.) Franco & Vasc. This study also reports two new record for the Brazilian Cerrado phytogeographic domain, S. conduplicate and S. radiata, of which the first is a new record for Maranhão State. Most specimens were found in riparian forest on rocky outcrops.

Five Achaeta species (A. affinis, A. bohemica sensu stricto, A. camerani, A. cf. danica, A. unibulba) and a new species, described here as A. tothi sp. n., were found during the investigation of the enchytraeid fauna of western Hungary (Őrség National Park and Kőszeg Mts.). Comparative morphological and molecular taxonomic investigations were performed with several individuals representing these six Achaeta species. A detailed description of the new species is given, and we also present some additional morphological data and photos about the other five Achaeta species. Such information could have importance in subsequent taxonomic studies and will aid the discrimination among the members of genus Achaeta. Furthermore, the obtained sequences could serve as references in forthcoming studies applying DNA-based taxon identification.

A biodiversidade da flora, o funcionamento e a conservação dos ecossistemas de ambientes degradados podem ser entendidos através de informações geradas por pesquisas florísticas. Assim, objetivou-se realizar um inventário florístico de fanerógamas do Parque Ambiental do Brejo do Buritis em Gilbués, Piauí. Para tal, foi realizado o método de ponto quadrante com quatro parcelas de 10x10 m2, na região que abrange uma nascente hídrica próxima à zona urbana. O material coletado foi herborizado, identificado, classificado e as duplicatas foram direcionadas ao acervo do Herbário Graziela Barroso da Universidade Federal do Piauí (TEPB), para ratificação da classificação e registro. Concomitantemente, foram realizadas análise observacional e estudo bibliográfico para caracterização do ecossistema e identificação de fatores relacionados à vulnerabilidade ambiental. A região em estudo apresentou vegetação típica com mata ciliar e trechos de vereda, no entanto, é uma área poluída com lixo doméstico, construção de moradia irregular e desmatamento, que podem influenciar o assoreamento do brejo. Foram coletadas trinta espécies de fanerógamas distribuídas em vinte e três famílias, destas, 50% foram incluídas no herbário e estão disponíveis para estudantes e pesquisadores. As mais representativas em número de espécimes foram Piperaceae (17,7%), Poaceae (11,1%), Arecaceae (6,6%), Cucurbitaceae (6,6%) e Vitaceae (6,6%). Foram identificadas espécies com propriedades farmacológicas, econômicas, bioindicadores, ornamentais e de uso em recuperação de áreas degradadas. Esta pesquisa possibilitou o conhecimento de uma amostra da biodiversidade vegetal do Parque Ambiental do Brejo dos Buritis, primordial para estratégias de conservação dos ecossistemas e reflorestamento, ações preconizadas pelos Objetivos do Desenvolvimento Sustentável (ODS) da agenda 2030.   Palavras-chave: Inventário Florístico. Degradação Ambiental.  Unidade de Conservação.   Abstract The biodiversity of flora, the functioning and conservation of ecosystems in degraded environments can be understood through information generated by floristic surveys. Thus, the objective was to carry out a floristic inventory of phanerogamous of Environmental  Park Brejo dos Buritis in Gilbués, Piauí. Thus, the Quadrant Point method was performed with four 10x10 m2 plots, in the region that covers a water source near the urban area. The collected material was herborized, identified, classified and the duplicates were directed to the collection of Graziela Barroso Herbarium of the Federal University of Piauí (UFPI), for ratification of classification and registration. Concomitantly, observational analysis and bibliographic study were performed to characterize the ecosystem and identify factors related to environmental vulnerability. The region under study presented typical vegetation with riparian forest and stretches of path, however it is a polluted area with household waste, irregular housing construction and deforestation, which can influence the swamp siltation. Thirty species of phanerogams distributed in 23 families were collected, of which 50% were included in the herbarium and are available to students and researchers. The most representative in number of specimens were Piperaceae (17.7%), Poaceae (11.1%), Arecaceae (6.6%), Cucurbitaceae (6.6%) and Vitaceae (6.6%). Species with pharmacological, economic, bioindicator, ornamental and recovery use of degraded areas were identified. This research allowed the knowledge of a sample of the vegetal biodiversity of the  Environmental Park Brejo dos Buritis, primordial for strategies of ecosystem conservation and reforestation, actions recommended by the 2030 Agenda Sustainable Development Goals (SDG).   Keywords: Floristic Inventory. Ambiental Degradation. Conservation Unit.

A new Tardigrada species, Claxtonia goni sp. nov. is described from specimens collected in the central area of the Haleakalā National Park, the island of Maui, Hawaii, U.S.A. The new species and Clx. pardalis (Degma & Schill, 2015) together with several examples of Clx. wendti (Richters, 1903) are the only known Claxtonia species with the plates having an intracuticular pattern resembling that on a leopard’s fur. Claxtonia goni sp. nov. differs from Clx. pardalis in the absence of pores on leg plates, in smaller and uniform pores on dorso-lateral plates, in very unequally spaced teeth in the dentate collar, in lesser ratio of internal cephalic cirrus and lateral cirrus A lengths, and in relatively shorter claws in fourth pair of legs. The differences between the new species and the other congeners as well as Echiniscus species with the same cirri composition and similar cuticular sculpture are also defined. The diagnosis of the genus Claxtonia is amended and three Echiniscus species are transferred into the genus with the proposed new combinations: Claxtonia aliquantilla (Grigarick, Schuster & Nelson, 1983) comb. nov., Clx. mosaica (Grigarick, Schuster & Nelson, 1983) comb. nov. and Clx. nigripustula (Horning, Schuster & Grigarick, 1978) comb. nov..

The Jaú National Park, located in the Amazon, is the largest National Park of Brazil and still its insect fauna is barely known. Herein we describe two new species of Psychodinae, Alepia iy sp. nov. and Parasetomima timmirima sp. nov., and report 19 other species of Psychodidae, subfamilies Phlebotominae, Psychodinae and Trichomyiinae collected from this Conservation Unit. Micrommatos Quate & Brown, represented by M. stephaniae Quate & Brown, and Platyplastinx culmosus Quate & Brown are recorded for the first time for Brazil. Among the collected phlebotomine sand fly species, three species have previously been implicated in transmission of Leishmania: Nyssomyia anduzei (Rozeboom), Psychodopygus ayrozai (Barretto & Coutinho) and Trichophoromyia ubiquitalis (Mangabeira).

A new species of Tomoptema, T. krugerensis, sp. n., has been recorded from the Kruger National Park, Republic of South Africa.Morphologically it is very similar to T. delalandei cryptotis (Boulenger) but the mating call is markedly different from that of the other members of the genus and this is coupled with small but consistent morphological differences.T. krugerensis sp. n. is known to occur only on a portion of the western fringe of the vast sandveld areas of Mozambique, but possibly has a much wider distribution. Mating call, calling behaviour, eggs, early development and defence mechanisms are described. The affinities of the new form are discussed and the mating calls of other members of the genus are reviewed. Mating call is again shown to be a sensitive non-morphological taxonomic tool.

<p class="5abstrak"><em>Papilio</em><em> blumei</em> is an endemic butterfly of Sulawesi and especially in Bantimurung Bulusaraung National Park. This research was to observed of the behaviour and natural enemies of <em>P. blumei</em> in Bantimurung Bulusaraung National Park. The behaviour of the insect were mating, foraging, competiting, ovipositing and mud-puddling. Life table was used for analysis of mortality factors, therefore the number of mortality was analyzed by key-factors formulation. The result indicated that mating strategies is patrolling. Foraging activity of the sixth instar was the highest compared to the other instars and the lowest one activity of the prapupa stadium of <em>P. blumei</em>. Nectar host plants for the imago of butterfly were <em>Sarcosephalum latifolius</em> and <em>Eugenia sp</em>. There was <em>Scudderia sp</em>. as an interspesific competitor for larval <em>P. blumei</em>. The intraspesific competitor of the imago stage was male of <em>P. blumei</em>. Female <em>P. blumei</em> laid eggs on abaxial leaf <em>E.hupehensis</em> and the eggs hatched after six days. The larva of  <em>P. blumei</em> has a overheating behaviour and the adults has a mud puddling. The natural enemies of <em>P.blumei </em>is <em>Trichogramma</em> sp., with k value = 0.381, <em>Pteromalus </em>sp., with k value = 0.125 and <em>Formica </em>sp., with k value = 0.096.</p>

Abstract A taxonomic treatment of the genera Turnera and Piriqueta in the state of Pernambuco, northeastern Brazil, is presented. Fourteen species of Turnera and six species of Piriqueta were found in the Atlantic Forest and Caatinga, of which nine are endemic to Brazil. Turnera pernambucensis is threatened and restricted to the Atlantic Forest of Pernambuco, while T. joelii is a new record for the state. The species predominate in steppe savanna and semideciduous seasonal forest, but several of them grow naturally in anthropized areas. Catimbau National Park is the locality with the highest species richness. Tristyly is recorded for the first time in Piriqueta guianensis. Identification keys, descriptions, illustrations, distribution maps, and comments about habitat, flowering, fruiting, and morphological relationships are provided.

In the Democratic Republic of the Congo (DRC), the protectionist conservatism influenced by colonialism, which exploited African countries for the prosperity of the colonizing countries, still has a high visibility in the Salonga National Park (PNS). If, in theory, the Central Africans seem to free themselves from the colonial powers on their land, in practice they are still there. The hostility of settlers who have become neo-colonists to the development of Central Africa remains intact, he adds (Ndinga, 2003). This reflects a "logic from above" that has disregarded local values. Yet, in the era of sustainable development and globalization, African protected areas appear to be essential tools for States to reposition themselves in a complex set of actors with the aim of capturing and using the new environmental rent (Giraut, Guyot, & Houssay-Holzschuch, 2003). This is a "bottom-up logic", placing people at the heart of all activities and aiming to reorganize their long-term relationships with the environment. From these two logics, a third "logic from the other side" emerges, reflecting a collective awareness of the fragility of the planet. The restoration of the rights of Africans in the various national frameworks constitutes a major challenge for the contemporary management of African protected areas. Because the protected areas inherited from the different colonial systems must accompany the change in management methods and the redefinition of their functions in order to better serve the local community in the long-term.
