Green vestment mantis (Phyllothelys qingjinum) from Malipo, Yunnan, with cross collar on pronotum

NEWS - Green vestment mantis (Phyllothelys qingjinum) from Malipo, Yunnan, China, is described based on geometric morphometric, genetic distance and molecular phylogenetic analyses. The discovery of this new species fills a significant distribution gap for the P. werneri group in southern Yunnan and highlights the need for further exploration in this region.

Phyllothelys Wood-Mason, 1876 (Mantodea, Hymenopodidae) includes 22 species with China being the hotspot containing 15 species in four groups, especially P. werneri which includes 6 species. This suggests a wide distribution across the mountainous region south of the Yangtze River extending from Medog in the west to Taiwan Island in the east.

P. qingjinum has dimensions (mm) with head to abdomen: 52.75-54.95, head to wing: 58.60-62.14, pronotum: 15.30-17.76, prozone: 3.46-3.95, metazone: 11.84-13.88, anterior coxa: 8.39-10.64, anterior femur: 9.36-11.46, anterior tibia: 5.55-7.02, posterior femur: 7.82-9.35, posterior tibia: 6.82-8.54, anterior wing: 32.03-36.79 and posterior wing: 28.70-33.16.

The new species has a distribution in Yunnan. The name is derived from the Chinese word ‘青衿’(Qingjin) which refers to the green cross-collared robe in ancient Hanfu. The term metaphorically refers to the distinctive green color of the dorsal edge of the pronotum of this species when alive.

The researchers compared with other species based on morphometrics with P. qingjinum being distant from the others. P. chuangtsei and P. werneri were each clearly separated from the other species. In contrast, P. jiazhii, P. jianfenglingense and P. dulongense were closer to each other showing considerable overlap.

P. qingjinum differs from the other species based on morphology and the colored patches on the prothoracic legs. The large, closely arranged colored patches in the discoid area of the forewings resemble those of P. jianfenglingense and P. dulongense. However, P. qingjinum shows a relatively prominent supracoxal dilatation with obvious lateral pronotal expansion.

P. chuangtsei shows lateral pronotal expansions developing around the supracoxal dilatation. However, P. qingjinum can be further distinguished by its larger size and the presence of numerous longer and sharper spines on the sdp and apha of the male external genitalia.

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 ...

Javanese grasshopper (Valanga nigricornis)

Wooden grasshopper or Javanese grasshopper ( Valanga nigricornis ) is an animal species of Acrididae, grasshoppers that have at least 18 subspecies, insects with very wide diversity in color and size, sexual dimorphism in which females are larger in size and paler in color. V. nigricornis in males has a length of 45-55 millimeters and females 15-75 mm. The head is square and green or yellow or brown or black in color. A pair of antennas has a black color. The eyes are large and gray or white or brownish. The hind legs are very large and have a green or yellow or brown or black color, plain or brindle. The limbs have two rows of large and long spines with black tips facing backward. The wings have a length exceeding the belly, a rough surface and are brown or green or yellow or black in color with pulse lines forming spaces filled with black color. The hind wings are rose red which will be visible when flying. Nymphs are pale green or yellow or brown or blackish in color. Javanese gr...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
