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.

Cogon grass (Imperata cylindrica)

Cogon grass ( Imperata cylindrica ) is a species of plant in the Poaceae, an annual grass, sharp leaves, long and scaly shoots, creeping underground, white or purplish flowers, very adaptive and grows in all climates. I. cylindrica has sharply pointed shoot tips that emerge from the ground, up to 3 meters high, short stems, rising above the ground surface. Leaves are long ribbon-shaped, pointed tip, narrow base, up to 100 cm long, very rough and sharply serrated edges, long hairs at the base and wide veins. Inflorescences in panicles, up to 28 cm long, spikes long-haired and white to 1 cm. The seeds spread quickly with the wind or via rhizomes that quickly penetrate the soil. This species grows in tropical to subtropical areas, elevation up to 2000 meters, temperature 20-40C, rainfall 500-3500 mm/year, pH 4-7.5, lots of sunlight to a bit of shade. This plant dominates open land, former forests, dry rice fields, roadsides and so on. This plant contains mannitol, glucose, sacharose...

A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis...
