Pseudomogrus logunovi
Pseudomogrus logunovi
Pseudomogrus logunovi is a small jumping spider that lives in the United Arab Emirates. It belongs to the jumping spider family Salticidae.
Discovery and classification
- First described in 2010 by Wanda Wesołowska and Antonius van Harten.
- It was originally placed in the genus Yllenus, later moved to Logunyllus in 2016, and finally assigned to the current genus Pseudomogrus in 2019.
- The species is named in honor of arachnologist Dmitri Logunov.
Where it is found
- Endemic to the United Arab Emirates.
- The male holotype was found near Wadi Bih in 2008.
- It has since been found in several emirates, including Ajman (2006), Ras Al Khaimah (2008), and Umm Al Quwain (2009).
What it looks like
- Size: Very small. Males have a cephalothorax about 1.5–1.8 mm long and 1.4–1.7 mm wide; abdomen about 1.6–1.8 mm long and 1.7–2.1 mm wide. Females are larger, with a cephalothorax about 1.7–2.0 mm long and 1.6–1.8 mm wide; abdomen about 2.0–2.2 mm long and 1.7–2.1 mm wide.
- Color and pattern: Males have a dark carapace with two white stripes; their legs are yellow with brown patches. The abdomen is whitish and hairy. Females have a brown carapace with lighter hairs; their abdomen is yellow or fawn, sometimes with a vague brown streak or grey spots.
- Distinguishing features: The male’s copulatory organs include a straight tibial apophysis on the pedipalps and a long embolus with a narrow terminal apophysis. The female has an oval epigyne with two elongated openings and short insemination ducts. These reproductive organs are key to telling this species apart from similar spiders.
Genetic and genus notes
- Pseudomogrus is related to several other genera in the Leptorchestini group within the broader Salticoida clade.
- The genus Logunyllus, once used for this species, is now considered a junior synonym of Pseudomogrus, so the species is correctly named Pseudomogrus logunovi.
