Lipas (Panesthia angustipennis)

Lipas (Panesthia angustipennis) is a species of animal in Blaberidae, a black, winged cockroach, nymphs having brown features on the upper back near the head, decomposer macrofauna which inhabit many wood residues in the forest ecosystem by eating wood that creates cavities producing wood shreds and fecal pellets.

P. angustipennis has a black or dark brown base color. Males have black heads with brown eyes, ocelli and yellowish brown upper lip. Black antenna with pale yellow apical segment. Sternite and reddish brown or black legs.

Females are similar to males, but rounded back margins, anterior pronotum margins with excision. The nymph is black, has four layers of upper back with four yellowish brown marks on the third and fourth layers, the stomach has six or seven layers.

Lipas live in the tropics with many woody trees for altitudes up to 1500 m. Noted four subspecies is Panesthia angustipennis ssp. angustipennis, Panesthia angustipennis ssp. cognata, Panesthia angustipennis ssp. spadica and Panesthia angustipennis ssp. yayeyamensis.

P. angustipennis has a very important meaning in the wood decomposition process including acacia. Wood cavity by macrofauna will expand the surface of the wood to be attacked by decomposer microorganisms. Wood residue is a source of food and a place to live.

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

Black nightshade (Solanum nigrum)

Ranti or black nightshade ( Solanum nigrum ) is a species of plant in the Solanaceae, shrub and short-lived, stems erect or lying on the ground, berries have a black color when ripe, grows in forests, agricultural land and disturbed habitats. S. nigrum has stems erect or lying at ground level, 30–120 cm (12 to 47 in) long, branched, tubular with several linear grooves forming a cone, green and white-haired. Leaves are elliptical to heart-shaped, 4-7.5 cm long, 2-5 cm wide, pinnate base, pointed or blunt tip, wavy edge or large toothed, dark green upper side, pale underside, hairy or hairless and has a stalk with a length of 1-3 cm. Flowers have greenish to whitish petals, curved when old and surrounded by bright yellow anthers. The berries are mostly 6-8 mm in diameter and are green then turn dull black or black purple or red. Black nightshade grows well with a soil pH of 5.5-6.5 and is rich in organic matter. It is difficult to grow under conditions of high temperature and high hum...

Redflower ragleaf (Crassocephalum crepidioides)

Sintrong or ebolo or thickhead or redflower ragleaf ( Crassocephalum crepidioides ) are plant species in Asteraceae, terma height 25-100 cm, white fibrous roots, generally grow wild on the roadside, yard gardens or abandoned lands at altitude 200- 2500 m. C. crepidioides has erect or horizontal stems along the soil surface, vascular, soft, non-woody, shallow grooves, green, rough surface and short white hair, aromatic fragrance when squeezed. Petiole is spread on stems, tubular and eared. Single leaf, spread out, green, 8-20 cm long, 3-6 cm wide, longitudinal or round inverted eggshell with a narrow base along the stalk. Pointed tip, flat-edged or curved to pinnate, jagged rough and pointed. The top leaves are smaller and often sit. Compound flowers grow throughout the year in humps that are arranged in terminal flat panicles and androgynous. Green cuffs with orange-brown to brick-red tips, cylindrical for 13-16 mm long and 5-6 mm wide. The crown is yellow with a brownish red...
