White Darwin wasp (Protoleptops nyeupe), a new species and the fifth in genus since Heinrich's description in 1967

White Darwin wasp (Protoleptops nyeupe) species baru dan kelima dalam genus sejak dideskripsikan Heinrich pada 1967

NEWS - Researchers established a new species, white darwin wasp (Protoleptops nyeupe) marking the first occurrence of an Ichneumoninae species in Burundi, first described a female P. farquharsoni Heinrich 1967 from KwaZulu-Natal, documented P. magnificus from Mpumalanga, South Africa, and P. angolae Heinrich 1967 from Uganda,

P. nyeupe can be easily distinguished from all other known species of the genus by the combination of characters of incomplete carination of the propodeum, absence of costulae and fused dentiparous area with area externa and area spiracularis.

The temples are straight and fused (P. farquharsoni, P. heinrichi and P. magnificus are prominent and not fused). The hind tarsus is white (P. farquharsoni, P. heinrichi and P. magnificus are fused). The presence of scopa that occupies 1/3 of the ventral part of the coxa (P. heinrichi does not have it, P. angolae and P. farquharsoni are small, P. magnificus occupies 2/3 of the ventral side of the coxa).

Mesocutellum is white (P. farquharsoni and P. angolae are reddish orange, P. heinrichi and P. magnificus have lateral white markings). T2 is striped longitudinally in the middle (P. angolae and P. farquharsoni are densely spotted). Petiolar area is sharply demarcated (P. angolae is not sharply demarcated). Mesopleuron is spotted on the surface and is sparse (P. angolae is densely and strongly spotted).

The specific epithet nyeupe is a noun in apposition derived from the Swahili word “nyeupe” for white. This name refers to the extensive white color of the mesoscutum and mesoscutellum which contrasts sharply with the dark color of the rest of the body.

This study presents a comprehensive revision of Protoleptops Heinrich, 1967, and extends its range. A specimen of P. nyeupe in a bush on the edge of a dirt road was collected together with several unidentified females of Cryptini (Ichneumonidae, Cryptinae) that had the exact same coloration pattern as the new species.

P. nyeupe and the Cryptinae stood out from the background as small whitish moving balls. Researchers scoured museums and collections for species and genera of Ichneumoninae and Cryptinae that have this distinctive coloration pattern in the Afrotropics.

The discovery of this surprising new species also marks the first record of the Ichneumoninae subfamily for Burundi, coupled with the first record of P. angolae in East Africa, demonstrating that knowledge of the diversity and distribution of Darwin's wasps in the Afrotropics is still lacking.

Liverwort (Marchantia)

Liverwort ( Marchantia ) is a genus of plants in the Marchantiaceae, growing vines and attached to the soil surface, soft, dark green, upright phallus like a cup, grows in colonies on slopes and vertical soil that is moist and shady. Marchantia has elongated strands, rounded ends, branched, flat margins and a black vein in the middle. The strands formed a circular formation, growing widely and forming new formations around it. Sexual reproduction involves sperm from antheridia in male plants to fertilize ova in archegonia in female plants. The zygote develops into a small sporophyte which remains attached to the larger gametophyte. The sporophyte produces spores which develop into free-living male and female gametophytes. Asexual reproduction via gemmae in the cup-like structures on the upper surface of the plant. Asexual reproduction can also occur when older plant parts die and new, surviving branches develop into separate plants. Kingdom: Plantae Phylum: Marchantiophyta Class: ...

Wild durian (Cullenia exarillata)

Wild durian ( Cullenia exarillata ) is a species of plant in the Malvaceae, a tall tree with smooth, greyish-white bark, peeling on older trees, a straight trunk, horizontal branches and often with a series of knob-like tubercles for flower and fruit attachment. C. exarillata has young branches and the underside of the leaves is covered with golden brown peltate or shield-like scales. The leaves are single, alternate, glabrous, glossy green on the upper side and covered with silvery or orange peltate scales on the underside. Hermaphroditic flowers are tubular and also covered with golden brown scales, 4-5 cm long and cream or reddish brown in color. Flowers have no petals, formed of tubular bracteoles and tubular calyxes, 5-lobed. Fruit is round, 10-13 cm in diameter, covered with thorns and clustered along the branches. Many seeds, reddish brown, 4-5 cm long and 2-3 cm wide. The seeds are enclosed by a fleshy, whitish aril. The fruit splits open when ripe and dries to release the s...
