Glymmatophora submetallica Stål 1855

The genus Glymmatophora ('Sculpturated' Millipede Assassin Bugs) was described by Carl Stål in 1853 (Stål, C. 1853. Nya genera bland Hemiptera. Öfversigt af Kongliga Vetenskaps-Akademiens Förhandlingar 10. https://archive.org/details/biostor-235032/page/n1/mode/2up ). 35 species of Glymmatophora are knowm from Africa. Glymmatophora submetallica Stål, 1853 is the type species of the genus.


Description by Stål 1855:
https://www.biodiversitylibrary.org/page/15969777#page/51/mode/1up
Dark steel-green; thorax, marginal spots on the abdomen, knees, tibiae and tarsi red, incisions on the thorax, the antennae and the base of the femora black. Length 19 mm, width 7 mm -
'Caffraria interior'

Female (after Horváth 1914): The whole head and the base of the femora are black. The segments of the connexivium are red with a black basal spot. The anterior lobe of the pronotum is marked with a black median vitta which is apically broader.

Eristalinus (Eristalinus) euzonus (Loew 1858)

Original description in:
Loew, H. 1858. Bidrag till kannedomen om Afrikas Diptera [part]. Öfversigt af Kongliga Vetenskapsakademiens Förhandlingar 14[1857]:
https://www.biodiversitylibrary.org/item/150443#page/393/mode/1up
Face greyish-pollinose, with a median black streak, shortened above; antennae black, the third joint round; thorax yellowish-hairy, scutellum fulvous, yellow-hairy. The abdomen of the male is very often black with the first segment and the base of the second, the following segments pale ferrugineous-rufous, the last segments darker brown; the abdomen of the female is shiny black, with three yellow bands on the second third and fourth segments, the band on the second segment are laterally widened, the bands on the third and forth segmens are equal and complete, covered very densely with yellow-white tomentum; the posterior margin of the fourth segment is marked with a yellowish-white band; the fifth segment of the female's basal band is very narrowly interrupted and white; the genitals of the male are black and shiny. Wings hyaline with a minute brown stigma.

Type locality: Cape of Good Hope

A very detailled description of the male's and female's abdominal pattern can be found in Loew 1860. Die Dipteren-Fauna Südafrika's 1. Abt
https://www.biodiversitylibrary.org/item/35325#page/343/mode/1up

Bezzi described a variety andersoni which is treated as a proper species in recent publications.

Distribution: Kenya, Tanzania, Congo, South Africa

Palparidius capicola Péringuey 1910

Thorax ashy grey with yellow patches. Forewing with hook-shaped band in the middle. Male with elongated ectoprocts.
Original description & illustration in:
Péringuey, L. 1910. Description of a new or little known species of the Hemerobiidae (Order Neuroptera) from South Africa. Annals of the South African Museum. https://www.biodiversitylibrary.org/item/30489#page/469/mode/1up
https://www.biodiversitylibrary.org/item/30489#page/483/mode/1up

Head of a greyish colour slightly edged with flavescent, labrum, forehead, vertex, and legs flavous, antenne entirely black, broadening considerably towards the apex; thorax ashy grey, with four or five sub-flavescent patches on the discoidal part; abdomen sub-flavescent with longitudinal broad fuscous black bands; wings hyaline with the patches fuscous, cross veins sub-flavescent or light brown, speckles distinctly brown. Fore wings each with three cross bands and a sub-basal spot, the first, sub-median, and the second, post-median bands are incised inwardly somewhat in the shape of a hook in the male, but in the female the first one is not distinctly hooked; the third one is more or less sharply triangular, somewhat in the shape of an arrow, and connected at the upper basal part with the pterostigma which is flavescent for a very short distance and fuscous afterwards; on the basal part of the disk are a few spots; the hind
border has a continuous series of them, and the nervules of the costal space are speckled with brown at the base. Hind wings also with three cross bands corresponding to the position of those of the anterior wings, but broader and therefore better defined; the first one, also hooked, extends from the border to three-fourths of the width; the second extends over the whole width, is strongly zig-zagged, and even occasionally narrowly interrupted in the centre, the upper part abuts on the distinct, elongated, flavescent white pterostigma, the apical band encloses a narrow hyaline spot, the hind border is edged with continuous macules from half the length to the apical band. Head and thorax sparsely, abdomen densely mbut briefly bristly and hairy, the bristles black, the hairs whitish; legs bristly and spinose. The arcuate, dilated basal part of the clasping organs of the g has inwardly two parallel hairy lobes, filling half the circumscribed space.

Length of body 29-31 mm.; clasps of male 11 mm.; fore wings expanded 70-81 mm.

Hab. Cape Colony, Carnarvon (Wyk’s Vlei), G. Alston; Beaufort West (Hottentot River), A. R. Walker.

Distribution: Western South Africa, Namibia, Botswana.
