Taxonomy
This page represents the following TreeOfLife-200M taxonomic path.[1]
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Diptera
- Family: Simuliidae
- Genus: Austrosimulium
- Species: Austrosimulium colboi
Taxonomic Note
While historically described as Austrosimulium colboi (Davies & Györkös, 1988), recent taxonomic revision based on molecular and morphological evidence has reassigned this species to the genus Paraustrosimulium [2].
Visual Description
Based on examination of specimens in the TreeOfLife-200M dataset, the species exhibits characteristic features of the family Simuliidae, including a compact, robust body form typical of black flies [1]. The specimens appear dark in coloration, consistent with the "blackish brown" or "black" descriptions found in literature [2].
Morphology
- Adult Female: Body length ranges from 1.9–2.3 mm. The antenna consists of 8 flagellomeres. The mandible is broadly triangular apically, featuring 48–50 inner teeth and 9–11 outer teeth. Cervical sclerites are notably developed [2].
- Adult Male: Body length ranges from 2.2–2.6 mm. The antenna has 8 flagellomeres and is narrower than that of the female. The ventral plate of the genitalia is directed ventrally and appears broadly concave apically, with a well-developed median keel [2].
- Pupa: The cocoon is slipper-shaped and medium brown, with a complete ventral floor. The gill consists of a single expanded tapered tube directed anteroventrally [2].
- Larva: Total length is 4.0–4.9 mm. The head is distinctly bicoloured with marked spots. The postgenal cleft is small and U-shaped [2].
Distribution
This species is known from Victoria, Australia [2].
