AbstractThe Longman’s beaked whale (Indopacetus pacificus) is one of the rarest cetaceans worldwide. Since it was first described as its own species in 1926, they have been observed alive at sea on several occasions, and less than 20 strandings have been reported worldwide to date. Thus, basic information regarding this species, such as the maximum size of adult individuals or body length at birth, remains unknown. In this study, the external appearance and DNA analysis of a female Longman’s beaked whale stranded on Miyako Island, Okinawa, Japan, are reported. The external appearance of the specimen matched the features of the Longman’s beaked whale presented in previous studies. The mitochondrial DNA control-region sequences obtained from the specimen also matched the reference sequences of the species deposited in GenBank. Based on these features, the specimen was confirmed as a Longman’s beaked whale. The specimen was estimated to be neonate because of its body length (235 cm) and the clear several fetal folds observed on its body surface. To the best of our knowledge, this is the first report of a confirmed new born neonate of Longman’s beaked whale in the world.

Beaked Whales

Beaked whales of the Family Ziphiidae are the least known of all cetacean families. Here, using mitochondrial DNA Control Region and Cytochrome B, and supported by morphological comparisons of skull and teeth, we identified a 4.6 m female beaked whale, stranded in Maco, Compostela Valley, Philippines on December 19 2012, as the Deranayigala's beaked whale,Mesoplodon hotaula. This is the first record ofM. hotaulain the Philippines and only the eighth specimen in the world.

Thelastomatidae is one of the largest families parasitizing insects, within the order Oxyurida. In this work we reported parasitism in nymphs and adults of Neocurtilla claraziana by two different thelastomatid species as a part of a field survey on agricultural pests. Nymphs and adults of this insect were isolated from grasslands of Buenos Aires State, Argentina using a tensio-active solution. The nematode species Gryllophila skrjabini Sergiev, 1923 and Cephalobellus magalhaesi Schwenk, 1926 are briefly described and measurements are given. Both nematodes are reported for the first time in Argentina with C. magalhaesi being the second isolation of this species in the world. Neocurtilla clarziana is a new host record for G. skrjabini.

Specimens of Drilocephalobus moldavicus are described from the Kelso Dunes area, Mojave National Preserve, southern California. This is the first record of the genus in North America. The specimens of this population are characterized by a body length of 322–417 µm in females and 403 µm in the male; cuticle finely annulated; lateral field with five incisures, extending to phasmid and two incisures extending almost to tail terminus in both sexes; lip region helmet-shaped, offset from body contour; lips amalgamated; stoma with thin walls lacking sclerotizations; pharynx without distinct divisions, cylindrical, widening slightly at about 1/3 of its length and basally, without valves; spermatheca 14–19 µm long; postvulval uterine sac 25–27 µm long; spicules 23 µm long; and female tail conoid-elongate with rounded terminus.

Two new species of the genus Laena Dejean, 1821 (Coleoptera: Tenebrionidae: Lagriinae) are described from Hong Kong: Laena hongkongica sp. n. and Laena walkeri sp. n. These constitute the first record of the genus from Hong Kong, as a species previously described from nearby area Laena ovipennis Schuster, 1926, in fact originated from Zhejiang province nearby Shanghai. Both species from Hong Kong possess a wide variation in body length, which is quite unusual for this genus.

Morphology-based identification of North AtlanticSebasteshas long been controversial and misidentification may produce misleading data, with cascading consequences that negatively affect fisheries management and seafood labelling. North AtlanticSebastescomprises of four species, commonly known as ‘redfish’, but little is known about the number, identity and labelling accuracy of redfish species sold across Europe. We used a molecular approach to identify redfish species from ‘blind’ specimens to evaluate the performance of the Barcode of Life (BOLD) and Genbank databases, as well as carrying out a market product accuracy survey from retailers across Europe. The conventional BOLD approach proved ambiguous, and phylogenetic analysis based on mtDNA control region sequences provided a higher resolution for species identification. By sampling market products from four countries, we found the presence of two species of redfish (S. norvegicusandS. mentella) and one unidentified Pacific rockfish marketed in Europe. Furthermore, public databases revealed the existence of inaccurate reference sequences, likely stemming from species misidentification from previous studies, which currently hinders the efficacy of DNA methods for the identification ofSebastesmarket samples.

The wild boar is one of the most dangerous invasive species. It is widespread in the world, including records for many Brazilian states. However, there is a lack of record from Maranhão state. In the present study, we reported a population of wild boar inside the Lençóis Maranhenses National Park, in Barrerinhas county, State of Maranhão. We discuss about the negative effects of this introduction on native species, including a record of predation by wild boar in nests of endangered turtles.
