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.

PromethION Sequencing Report:

Output:

34.81 Gigabases

Approximate N50:

1.09 kilobases

Draft Genome Assembly Statistics:

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.

Porthetes sp. nov.
(ex Encephalartos horridus)

Cycad pollination weevil

Species Card Details

Importance:

Porthetes beetles are pollinators of Encephalartos cycads. Both the cycads and weevils have a high extinction risk. Genome sequencing provides a basis for further molecular studies to understand host specificity and options for conserving and recovering pollinator interactions.
