Etymology. Unknown, probably from the characteristic costal area in the forewings.

Type locality. South Africa, Western Cape Province. Cape of Good Hope (“ CGH ”)   . Type locality subsequently designated by Tjeder (1967): Clanwilliam, 32°10’S 18°53’E.

Type depository. OXUM   .

Diagnosis. Nemia costalis   resembles N. elongata   by the same head colouration and abdominal pubescence patterns. Nemia costalis   can easily be distinguished from N. elongata   by the broad forewings with rounded apex ( Fig. 165 View FIGURES 162–166 ), while in N. elongata   the forewings are more slender and the apex is short and acute ( Fig. 163 View FIGURES 162–166 ).

Size (mm). Male: body length 10.9 (9.1–14.1); forewing 24 (21.6–28.4); hind wing: 52.2 (41.3–63.6); antenna 20.7 (14–24.2). Female: body length 10.4 (10.2–15); forewing 23.6 (20.4–27.9); hind wing 51 (41–61.4); antenna 15 (10.2–19.7). (N = 118).

Distribution and habitat. This species is confined to the Western Cape Province, South Africa ( Fig. 173 View FIGURES 172–177 ). The collection sites fall within the greater Cederberg Region. This area stretches from the town of Clanwilliam in the North to Citrusdal in the south in the Olifants River valley. The habitat in this region is typified by a Mediterranean climate with cold, wet winters and hot, dry summers ( Cowling et al. 1996). The vegetation is composed of strandveld, renosterveld and fynbos.

Remarks. Westwood (1836) described Nemoptera costalis   (= Nemia costalis   ) and Nemoptera angulata   (= Nemia angulata   ) in the same paper as two distinct species. However, this classification was disputed by Hagen (1866) who synonymised N. costalis   with N. angulata   and, inversely, Kirby (1900) and Navás (1910) synonymised N. angulata   with N. costalis   . Tjeder (1967) recognised that they represented two distinct species and consequently redescribed both in his paper ( Tjeder 1967).
