Hesse (1969) described this species as follows: Female: Body with the integument of dorsum of thorax distinctly more coarsely rugulose, with an indication of a submedial groove discally on each side; that of metanotum on the other hand less coarsely rugulose, more shining; antennal segments 1-3 pale yellowish brownish; reddish on sides of thorax narrower; metanotum entirely black; hind margin of tergite-1 much broader yellowish and tergites-2 and -3 entirely and conspicuously yellowish discally above; legs distinctly more brownish or reddish brownish, only the knees and bases of hind femora yellowish. Vestiture on head, sides of tergites 1 and 2 longer, denser, but that on femora comparatively shorter and less dense; hairs on abdomen posteriorly more whitish. Wings similarly infuscated, but middle parts of marginal and first submarginal cells more broadly and more distinctly clearer, and posterior vein of third posterior cell with more distinct, though faint, fuscous borders; knobs of halteres brownish above. Legs relatively shorter, the hind femora not only shorter, but comparatively slightly more rapidly thickened in apical part, being more clavate. In other respects it is indistinguishable from the females of C. longirostris and their various colour-forms. Length of body: about 15.5 mm; Length of wing: about 11 mm.

This species is represented in the collections by a single female specimen and closely resembles the female of C. longirostris, but differing in many respects included in the morphological descriptions.

Type locality: South Africa, Northern Cape at Okiep.

South Africa.

This genus is endemic to South Africa and Namibia (Kirk-Spriggs & Sinclair 2017). This species was collected in the Northern Cape: Namaqualand: Okiep (L. Péringuey, 20 Nov. 1885) (Hesse 1969).

The information below was extracted from Cannings and Scudder (2005): Dipterans are primarily aerial insects and the mesothorax, which bears the only pair of wings, dominates the thorax - the prothorax and metathorax are greatly reduced. The legs are normally rather simple and are used primarily for perching; in some groups, they are modified for prey capture or for signaling during courtship. The tarsi are nearly always 5-segmented. The functional wings are membranous and their pattern of veins is critical in fly classification and identification. During the evolution of flies, there has been a trend towards a reduction in veins, especially in the rear half of the wing – changes that evidently relate to improvements in two-winged flight. The hindwings, present in most other insects, are reduced in Diptera to small, club-like organs, called halteres, used for stabilising flight.

Herbivore - Nectarivore (nectar-eating)

The flies in this family are not known to hunt, catch or prey upon other insects as asilids do. They are however known to imbibe on the flower nectar especially Afroleptomydas and Cephalocera. These species sometimes visit flowers, especially those of species of Mesembryanthemum (Hesse 1969).

Like the others, flies in the Mydidae family begin life as an egg, which hatches into a grub-like larva. Most of the fly life is spent in the larval stage, mainly eating and growing as well as molting several times. Some flies may spend at least a year as a larva. The next stage is a pupa, during which the insect transforms into its final stage, emerging from the pupa as a winged adult, able to mate and reproduce. In many species, males stake out positions at favourable egg-laying sites and wait for females to arrive (Hesse 1969).
