Eight new Palaearctic wasps species of Apsilocera Bouček 1956, female and 2 species for the first time described

NEWS - The researchers reviewed 12 Palaearctic species of Apsilocera Bouček 1956 with 8 new species described, the female Apsilocera verticillata Bouček 1956 was described for the first time, Apsilocera dupla Mitroiu & Achterberg 2013 and A. elongata Mitroiu & Achterberg 2013 were recorded from the Palaearctic for the first time.

The pteromalid genus Apsilocera Bouček 1956 with the type species A. verticillata Bouček 1956 belongs to the family Pteromalidae, subfamily Pteromalinae and is distributed in the Nearctic, Palaearctic, Oriental and Australian regions. It currently includes 19 species with only A. bramleyi Graham 1966 and A. verticillata Bouček 1956 found in the Palaearctic region.

Another species A. breviscapus Bouček 1993 is distributed in the Nearctic region. Three species, A. australis Bouček 1988, A. bidens (Bouček, 1988) and A. brevis (Bouček, 1988) are distributed in the Australian region.

Thirteen other species are distributed in the Eastern region: A. acuticristata Mitroiu & Achterberg 2013, A. bicristata Mitroiu & Achterberg 2013, A. brevivena Xiao & Huang 2001, A. cornuta Mitroiu & Achterberg 2013, A. dentata Mitroiu & Achterberg 2013, A. dupla Mitroiu & Achterberg 2013, A. elongata Mitroiu & Achterberg 2013, A. fulvipennis Mitroiu & Achterberg 2013, A. longicornis Mitroiu & Achterberg 2013, A. pallikava Mitroiu & Achterberg, 2013 and A. tuberculata Mitroiu & Achterberg 2013.

Unfortunately, the biology of most Apsilocera species is unknown, but most were collected near dead trees in forests. Only A. bramleyi is known to parasitize small diptera of the family Cecidomyiidae: Cecidomyia sp. and Mycocecis ovalis Edwards 1922.

The eight new species are Ray Douglas Bradbury wasp (Apsilocera bradburyi) Tselikh, Lee & Ku (Republic of Korea), Buddha wasp (A. budai) Tselikh, Lee & Ku (Republic of Korea), elegant wasp (A. eleganta) Tselikh, Haas & Ku (Republic of Korea, Sweden), wide stigma wasp (A. grandistigma) Tselikh, Lee & Ku (Republic of Korea).

Jeju Island wasp (A. jejuensis) Tselikh, Lee & Ku (Republic of Korea), Marina Kopylova wasp (A. marina) Tselikh, Lee & Ku (Republic of Korea), Totoro wasp (A. totoroi) Tselikh, Haas & Ku (Germany, Japan, Sweden) and Vladimir Trjapitzin wasp (A. triapitzini) Tselikh, Haas & Ku (Russia, Republic of Korea, Sweden).

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 ...

Red costate tiger moth (Aloa lactinea)

Red costate tiger moth ( Aloa lactinea ) is an animal species in the Erebidae, a moth with a wingspan of 40 mm, a yellow belly, black antennae with red basalt joints, dark red palpi on the sides and white below, black terminal joints, living in forests and agriculture in the lowlands to mountainous areas. A. lactinea has a white head with a red stripe on the back. Thorax is white. The wings are predominantly white in color with black dots on each corner of the cells and a red margin. The wings have branched pulse lines and a starchy surface. The wing-covered upper abdomen is black with large elliptical plots and is colored yellow forming cells. The lower abdomen is white and has fine hairs that fall out easily. A pair of antennas is black. The forelegs are red, white and black. The other legs are white on the top and black on the bottom.
