Three new species of Huntsman spider (Pseudopoda Jäger 2000) from Qizimeishan National Nature Reserve

Three new species of Huntsman spider (Pseudopoda Jäger 2000) from Qizimeishan National Nature Reserve

NEWS - A spider survey in Qizimeishan National Nature Reserve in Xuan’en County, southwest Hubei Province, adjacent to the northeastern edge of the Yunnan-Guizhou Plateau, discovered three new species: arc huntsman spider (Pseudopoda arcuata ♀), Qizimeishan huntsman spider (Pseudopoda qizimeishanensis ♂ ♀) and Mian Wei huntsman spider (Pseudopoda weimiani ♂ ♀).

The reserve covers a total area of 345.5 km2 and the highest peak is about 2010 meters. It mainly protects the central subtropical mountain evergreen broadleaf forest and subalpine sphagnum swamp wetland area. The reserve is rich in wildlife resources and has been listed as a key biodiversity area in the China Biodiversity Conservation Action Plan.

Pseudopoda Jäger 2000 is the largest genus of the Sparassidae Bertkau 1872 with 256 species. Currently, 155 species of Pseudopoda are known in China. This genus is a small to large spider that lives mainly in leaf litter and less frequently in plants.

P. arcuata derives its specific epithet from the Latin word meaning "arch-shaped" referring to the curved LL. Females resemble P. allantoides Zhang, Jäger & Liu 2023, but P. arcuata can be recognized by its horizontally elongated S and FD appearing anterior to the S (vs. S elongated longitudinally and FD appearing medial to the S).

P. qizimeishanensis derives its specific epithet from the type locality, Mount Qizimeishan. Males resemble P. baoshanensis Zhang, Jäger & Liu 2023, but P. qizimeishanensis can be recognized by the long RTA and occurs in the basal part of Ti, T without prolateral growth and E tip pointing towards 11 o'clock (vs. short RTA, occurs in the medial part of Ti, T with prolateral growth, E tip pointing towards 7 o'clock).

Females resemble P. nanyueensis Tang & Yin 2000, but P. qizimeishanensis can be recognized by the long S, with wrinkles, almost parallel to the anterior edge of LL (vs. S without wrinkles and extending horizontally).

P. weimiani is named after one of the collectors, Mian Wei. Males resemble P. hongqi Deng, Zhong, Irfan & Wang 2023, but P. weimiani can be recognized by the short-smooth RTA and twisted EP (vs. RTA long and gradually narrowing towards the tip, EP without twists, terminal not exceeding E).

Females resemble P. taipingensis Zhang, Jäger & Liu 2023, but P. weimiani can be recognized by the nearly straight posterior margin of the LL, parallel to the anterior margin and the S with a clear bend in ventral view (vs. the W-shaped posterior margin of the LL, the S with a tube-like structure).

Pseudopods are widely distributed throughout China with 155 species accounting for about 61% of the world's total species. The majority are found in the southwest region, especially in the Yunnan-Guizhou Plateau, with 84 species highlighting the rich biodiversity and varied topography.

Qizimeishan National Nature Reserve, part of the northeastern extension of the Yunnan-Guizhou Plateau, has a diverse landscape with elevations ranging from 650 to 2010 meters. This variation creates a variety of microclimates and habitats that support a variety of species. However, research on spiders in this area is still limited.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

Cempaki (Termitomyces microcarpus)

Cempaki ( Termitomyces microcarpus ) is a species of fungus in the Lyophyllaceae family. It grows wild in tropical Asian forests near termite nests. It is rarely reported in urban areas. It is edible and known for its deliciousness, high nutritional value, and difficulty in cultivating. In Indonesia, it is used as an alternative food ingredient. T. microcarpus is the smallest of the Termitomyces species, umbrella-shaped, plain white, measuring 5 cm tall and 2.5 cm wide. It grows in dense clusters on surfaces and forms a mutualistic relationship, requiring the metabolic activity of termites as a substrate for growth. This species is known for its deliciousness, rich in nutrients, and has potential bioactive properties, such as helping lower cholesterol and acting as a tonic. Currently, it is difficult to cultivate on a large scale, and people rely solely on wild harvests. This mushroom is highly favored for its savory, delicious flavor and soft, chewy texture. It is often stir-fried ...

Oceanitis abyssalis, the deepest sea fungus at 5707 meters from sunken wood

NEWS - Researchers report a new species of deep-sea fungus, Oceanitis abyssalis , described based on SU rDNA sequence analysis and morphological characteristics. The specimen was found attached to a branch of Prunus sp. at a depth of 5707 meters on the abyssal plain in the Northwest Pacific Ocean, east of the Japanese Islands. This discovery is the deepest recorded for a marine fungus. Previous research by an international team in the Ocean Species Discoveries project reported 11 new species of ocean animals at a depth of 7000 meters . Oceanitis Kohlm (1977) grows on a variety of plant species in a variety of coastal to deep-sea environments. This genus is also widespread in geologically isolated deep-sea areas as one of the most successful fungal taxa in these environments. The thick peridium allows it to adapt to extreme deep-sea conditions. The morphology of O. abyssalis is very similar to O. scuticella Kohlmeyer, but O. abyssalis having unicellular ascospores, smaller deciduous...
