Hogna angusta
This record describes Hogna angusta (species). Recorded family: Lycosidae. Recorded order: Araneae.
Identification and Appearance
At one point described as an inland form (FL) of H. timuqua due to the male palp being identical, and species being similar in appearance. However, there is obvious difference in the female epigynum, currently separating the two. H. timuqua adult females are easily identified by a small, protruding (deeper), and more square shaped epigynum as opposed to the typical elongated shape of female angusta and other species in the lenta group. H. angusta can be significantly larger than H. timuqua . Wallace, 1942 Fig. 5,6 male Fig. 19 female Fig. 27 triangles Differences listed in H. timuqua description.

About Spiders: the wider group
Order-level background for Araneae, the group containing Hogna angusta. Species-specific details appear above.
Group overview
As of 2023, 51,673 spider species in 136 families have been recorded, though an estimated 150,000 species exist. Spiders rank 7th in total species diversity among all organism orders. Only 0.5% of spider species pose any risk to human health.
Ecological role of the group
Spider venom contains complex peptides with diverse pharmacological activities, making them valuable for drug development research. Spiders produce up to 7 types of silk from specialized glands. Spider silk genes have been inserted into mammals and plants for biotech applications.
Economic and practical significance of the group
The global spider community kills an estimated 400-800 million tons of prey annually (2017 study). Spiders provide billions of dollars in natural pest control for agriculture. Spider silk is 5× stronger than steel of the same diameter, driving a biomaterials research industry.
Recorded sources for this group: World Spider Catalog, PNAS, Nature, ScienceDirect. Imported estimates may describe particular regions or reporting periods.
