Guizhou slug moth (Fignya qiana), triangle slug moth (Fignya trigonum) and Samkos slug moth (Fignya samkosa)

NEWS - Researchers have established the taxa Guizhou slug moth (Fignya qiana), triangle slug moth (Fignya trigonum) and Samkos slug moth (Fignya samkosa) from China and Cambodia as new species in the genus Fignya Solovyev & Witt, 2009.

Fignya is a small genus established in the family Limacodidae with two species F. melkaya Solovyev & Witt, 2009 and F. ravalba Wu, Solovyev & Han, 2022. The type species, F. melkaya, was first discovered in northern Vietnam on Mount Fan-si-pan and then F. ravalba in China.

Jun Wu and Huilin Han from Northeast Forestry University in Harbin proposed a slight extension of the definition of the genus with a focus primarily on the male genitalia. During examination of moths from southwest China and Cambodia several specimens were identified that morphologically resembled the two known relatives, but dissection revealed differences in the structure of the male genitalia.

F. qiana is not much different from F. melkaya, F. ravalba and F. trigonum, but the overall color is lighter. This species can be clearly distinguished from the other species by the characteristics of the male genitalia.

F. trigonum has a prominent inner cucullus, a well-developed thick and long horn-like cornutus at the base of the vesicle and triangular sclerites, while F. melkaya and F. ravalba have smooth inner cucullus and a well-developed horn-shaped basal cornutus and no triangular sclerites.

F. samkosa is most similar to the new combined species, F. brachygnatha comb. nov. but the male genitalia can be clearly distinguished. F. samkosa has a relatively straight valve, a small triangular hairy fold at the base of the valve, and a slender phallus, whereas F. brachygnatha has a slightly inward-curved valve, no hairy fold at the base of the valve, and a thicker phallus.

F. qiana was found in Guizhou (China) and the new name comes from the abbreviation of Guizhou Province, “Qian”, which is the type locality. F. trigonum is from Yunnan (China) and the name comes from the Latin “trigonum” meaning triangle, referring to the unique triangular sclerite at the base of the bladder. F. samkosa is from Cambodia and is named after the type locality, Phnom Samkos Wildlife Sanctuary.

Dry Valleys on Antarctic continent is the driest place in the world

The Sahara Desert is the largest desert in the world, rainfall is very low, only stretches of sand and rocks without rivers and plants further strengthen the view of drought. However, it turns out that the place is not the driest place in the world. Dry Valleys in Antarctica, although the continent is covered in ice, but has one part that is completely dry. Although the average rainfall in most of the Sahara Desert is less than 20 millimeters per year, there are still drier places. Dry Valleys in Antarctica is much drier where the average rainfall is 0 millimeters per year and gets the title of the driest place in the world. The valleys have so low humidity that there is almost no ice. This is the largest ice free place on the Antarctic continent. The area is surrounded by mountains that block ice from flowing into the valley. Drought is also caused by strong katabalic gusts from mountain peaks where cold air blows down the hill due to gravity. The wind has speeds of up to 322 k...

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 ...

Tripa tiger moth (Nannoarctia tripartita)

Tripa tiger moth ( Nannoarctia tripartita ) is an animal species in the Erebidae, a moth with a forewing length of 14-18 mm, predominantly black or dark brown with white and orange hues, thick fur on the dorsal surface, long legs and antennae, living in forest scrub and agricultural land. N. tripartita in females has forewings 15-18 mm long, black or dark brown with slightly oblique transverse and few spots. The hind wings are yellow with large dark discal points and three other dots. Males have forewings 14-17 mm long, black or dark brown with transverse oblique postdiscal bands and several spots. The hind wings are yellow with brown costal margins, discal confluent points, wide ridges on the crest and angular points in the tornus. The head has a thin orange pattern and a pair of long black antennae. Long legs are black. Tripa tiger moths live in forest scrub, farmland and roadsides. More stationary by sticking to the leaf surface at the top. Kingdom: Animalia Phylum: Arthropod...
