Group:
Insect
Estimated genome size:
Its body is about 16-21 mm, and its probiscis (tongue) is 20-47mm long.
Size:
Its body is about 16-21 mm, and its probiscis (tongue) is 20-47mm long.
Distribution:
Its range is in south western Africa, specifically extreme southwestern Namibia through the western part of Northern Cape Province in South Africa (Namaqualand), and into the northwestern portion of the Western Cape Province. Key areas of high diversity include the Kamieskroon area of Namaqualand and the Pakhuis Mountains in the Western Cape.

Genome Length:
0.56 Gigabases
BUSCO completeness score (single and duplicated genes):
99.0% [S: 94.7%, D: 4.2%]
Importance:
The Long-tongued fly is important ecologically. It is a keystone pollinator for a whole guild of long-tubed, vividly colored flowers. Through its specialized morphology and behavior, it facilitates efficient and species-specific pollination, supports plant biodiversity, and likely drives co-evolution in its plant partners.

Labeo rosae
Rednose labeo

Importance:
The Rednose labeo is a freshwater fish endemic to Southern Africa. Preliminary unpublished short DNA sequence data suggest additional taxonomic diversity within this taxon, but comprehensive genomic data are necessary to resolve its phylogenetic relationships and refine its taxonomic diversity. Although the species is currently listed as Least Concern on the IUCN Red List, its population is experiencing a decline due to impacts of human activities. The Rednose labeo is important for subsistence fisheries.
