Describing spatial and temporal occurrence patterns of wild animal populations is important for understanding their evolutionary trajectories, population connectivity, and ecological niche specialization, with relevance for effective management. Throughout the world, blue whales produce stereotyped songs that enable identification of separate acoustic populations. We harnessed continuous acoustic recordings from five hydrophones deployed in the South Taranaki Bight (STB) region of Aotearoa New Zealand from January 2016 to February 2018. We examined hourly presence of songs from three different blue whale populations to investigate their contrasting ecological use of New Zealand waters. The New Zealand song was detected year-round with a seasonal cycle in intensity (peak February\–July), demonstrating the importance of the region to the New Zealand population as both a foraging ground and potential breeding area. The Antarctic song was present in two distinct peaks each year (June\–July; September\–October) and predominantly at the offshore recording locations, suggesting northbound and southbound migration between feeding and wintering grounds. The Australian song was only detected during a 10-day period in January 2017, implying a rare vagrant occurrence. We therefore infer that the STB region is the primary niche of the New Zealand population, a migratory corridor for the Antarctic population, and outside the typical range of the Australian population.

Gryllotalpa weisei Simeu-Noutchom \& Kekeunou sp. nov. was collected only in Tombel in the South-West region of Cameroon, during a survey conducted from March 2016 to March 2018 in the West, South-West and Centre regions of Cameroon. This species is close to Gryllotalpa microptera, collected for the first time in Cameroon during these investigations, only in the West region. G. weisei is different from G. microptera due to the hind wings that are vestigial; average fore wings length of 5.85\±0.56 mm in male and 5.34\±0.45 mm in female, not reaching the fifth abdominal segment; anal end of fore wings slightly concave; a stridulatory file with 54\±8.02 teeth (47\–71) in average, fairly spaced, with an average of 30\±5.06 teeth per millimeter; hind tibia bearing 11 spines; internal process of ectophallus quite short. G. weisei abounds in mixed crop fields, followed by cocoa agro-forests; it is scarce in grassy fallows and in forest undergrowth. G. microptera was present in all types of vegetations in Bafoussam, Babet\é and Bangoulap in the West region where it has been abundant in mixed crop fields, grass-fallow and coffee agro-forest but rare in forest undergrowth.

The Ecuadorean species Dichopetala andeana Hebard, 1924, is transferred to the new genus Cohnia. Cohnia g. nov. is characterized by short pronotum, subexagonal undivided elongated female subgenital plate, regularly up-curved and coarsely serrulated ovipositor, male simple cerci and presence in male of a structure titillators-like. Cohnia andeana comb. nov. is extensively illustrated and described, its song is presented for the first time as well as some ecological data.

The reproductive biology of the Myristica Swamp tree frog (Mercurana myristicapalus- tris), a monotypic rhacophorid frog endemic to the foothills of the Western Ghats mountains of India, has remained unknown since the description of the genus and species. We monitored individuals from parental generation amplexus to the comple- tion of offspring generation tadpole metamorphosis. Surprisingly, our observations revealed that this species exhibits many previously unknown characteristics, including the first ever record of the female, and a diverse call repertoire, consisting of five different call types (the functions of which remain incompletely known). We were also able to determine that reproductive activity peaked during the late pre-monsoon season, that males engaged in intraspecific aggressive encounters to occupy and to defend desirable territories, and that oviposition took place in terrestrial nests made by females. Embryonic development in the unattended nest was followed by tadpole development, which concluded within 40 days. The specific breeding mode employed by Mercurana, which restricts its range to the endangered Myristica swamp ecosystem, likely renders it susceptible to multiple threats, which should be considered jointly in future conservation planning.

Field and laboratory observations of Cylindraustralia kochii are presented with notes on some congeners. Nymphs and adults create galleries in moist soil by compression of the soil with their powerful fore legs, burrowing to depths of up to 1.9 m. During the cooler months and 1ñ2 days after rain, sandgropers commonly burrow long distances close to the soil surface producing conspicuous raised trails. Adults and nymphs of various sizes were found throughout the year. Eggs and early immatures of the genus (and family) are described for the first time. Pedicellate eggs of C. kochii were suspended singly in closed chambers 40ñ190 cm deep in moist soil. A ëlarvalí stage hatches from the egg and moults to a first instar nymph while still in the egg chamber. Five nymphal instars are indicated by morphometric and morphological data. Eggs are laid from autumn to spring but hatching was only observed in mid summer. A duration of at least 12 months is indicated for first instar nymphs, so the complete life cycle may extend over several years. Examination of gut contents revealed that sandgropers are omnivorous, consuming a wide array of plant, fungal and arthropod material. Plant food included root, stem, leaf, flower and seed tissue. Cannibalism occurred in one very dense population of C. kochii. Otherwise, no insect predators or parasitoids were encountered. Associated organisms included gregarines and Amoeba (Protista) in the intestines, rhabditid nematodes in the genital chambers of adults, and six species of mesostigmatid and astigmatid mites which adhered externally to the body. Nymphs and adults produce an odorous, probably defensive secretion from a pair of abdominal glands.

Although Eurycorypha is the most species-rich Phaneropterinae genus in Africa, little is known about the distribution and the ecology of the species. In this study data on distribution, ecology, song and on chromosomes of some East African species are provided. The nymphs of some species are shown, famous for their ant-like appearance and behaviour. The male of E. punctipennis Chopard and three species of Eurycorypha are newly described. These are E. resonans n. sp. and E. combretoides n. sp. occurring in different habitats on Mount Kilimanjaro, and E. conclusa n. sp from forest habitats along the Tanzanian coast. Bioacoustically, the four recorded species are unusually divers, presenting non-resonant and resonant songs. As four Eurycorypha species occur syntopically on geological young Mount Kilimanjaro, the biogeographical pattern and possible speciation mechanisms in the genus Eurycorypha are discussed in context of the climatical history of eastern Africa.
