Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica. [1]

Contents

Life style

They live in burrows that are open and not closed with a trapdoor. [2]

Description

The typical eye pattern of Hogna species: the width of the bottom row of eyes is less than the width of the two largest eyes in the middle row. Eye Arrangement of a Hogna Wolf Spider.png
The typical eye pattern of Hogna species: the width of the bottom row of eyes is less than the width of the two largest eyes in the middle row.

The genus has never been properly revised, even in Europe, and a reliable diagnosis is lacking. [2]

The genitalia are very conservative and closely resemble those of many other lycosine genera, making diagnosis on genitalic characters alone difficult. Characters that may be significant include the form of the female epigyne with a very long, relatively narrow longitudinal bar of the central T-shaped structure, the dorsal color pattern with the central longitudinal pale stripe of the prosoma extending the full length as far as the posterior median eyes, the abdominal pattern with a central lanceolate mark flanked by two darker longitudinal stripes, and the dense ventral scopulae present on tarsi and metatarsi of all legs. [2]

However, the African fauna includes specimens that differ somewhat from this in either genitalic or somatic characters, some appearing intermediate between Hogna and Trochosa . [2]

Hogna carolinensis is among the largest spiders found in the United States; females may have a body length of from 22 mm (0.87 in) to 35 mm (1.4 in). The carapace of H. carolinensis is characterized by an overall dark brown coloration, usually without any patterned variations. Its abdomen has a slightly darker stripe down its center, and its ventral side is black. This spider typically dwells in a vertical tube dug into the ground that may reach as deep as eight inches.[ citation needed ]

Taxonomy

The genus is in need of revision. [2]

Etymology

The word Hogna might be a rough latinization of one of the Greek words ὄχνη (ókhnē) "pear" or ὄγχνη (ónkhnē) "pear-tree". [3]

Species

As of October 2025, this genus includes 229 species and four subspecies. [1]
