range of genus

Pyrrhoscolia is a genus of scoliid wasps in the subfamily Scoliinae. It is native to the Afrotropics, where they have been recorded in various Afromontane regions. They are external parasitoids of beetle larvae. [1] The wings of all three species are noted for their brilliant lustre. [2]

Description

Horizontal lobes of the propodeum Pyrrhoscolia fax, lobbe van propodeum, a.jpg
Horizontal lobes of the propodeum

The body and its vestiture are black, apart from the apical segments of the abdomen which are bright reddish in both sexes (3 segments in females, 4 in males). Two species of Scolia are similarly coloured, but have swarthy wings and a red spot in each ocular sinus (or sini oculares, the "bays" bordered by the kidney-shaped eyes). In males, unlike Scolia, the propodeum has two distinct horizontal lobes, which project well behind the insertion of the petiole. [2]

The forewings lack the second recurrent vein and third submarginal cell in both sexes. The wings are closely striolate apically, as with the Scoliidae generally, and feature strong blue, blue-green or golden-green effulgence. [2] The eyes are deeply notched, as with the family generally. [3] On the faces of females the front and frontal space (or spatium frontale, located between the antennae [4] [5] ) are separated by a distinct furrow, though not so in males. The male genitalia are distinctive. [2]

<span class="mw-page-title-main">Scoliidae</span> Family of wasps

The Scoliidae, the scoliid wasps, are a family of wasps comprising about 560 species worldwide. They tend to be black, often marked with yellow or orange, and their wing tips are distinctively corrugated. Males are more slender and elongated than females, with significantly longer antennae, but the sexual dimorphism is not as apparent as in many of the Tiphiidae and Thynnidae.

The Narina trogon is a largely green and red, medium-sized, bird of the family Trogonidae. It is native to forests and woodlands of the Afrotropics. Though it is the most widespread and catholic in habitat choice of the three Apaloderma species, their numbers are locally depleted due to deforestation. Some populations are sedentary while others undertake regular movements.
