Etymology
The specific epithet kompirensis refers to the location "Saga, Kompira" in Japan, near Nagasaki. Bösenberg & Strand (1906) repeatedly mentions this location for specimens collected by Dönitz.
Taxonomy
The species was originally described as Meta kompirensis by Wilhelm Bösenberg and Embrik Strand in 1906.[2] At the same time, the synonym Meta vena was described by Dönitz & Strand.[2] In 1955, Yaginuma synonymized Meta vena with Meta kompirensis.[3] The species was transferred to the genus Metleucauge by Herbert Walter Levi in 1980.[4]
Distribution
Description
Females are larger than males, with total body length ranging from 10.7–15.6 mm compared to males at 5.7–7.8 mm. The cephalothorax in females measures 4.2 × 3.4 mm, while in males it is 2.6 × 2.1 mm. The opisthosoma is 6.5 × 4.3 mm in females and 3.1 × 2.0 mm in males.[5]
The species can be distinguished from the closely related Metleucauge yunohamensis by several characteristics: the "V"-shaped marking on the carapace is uniform without light-colored spots, the anterior portion of the abdominal folium is distinct and darker, the middle bulge of the epigyne is sub-spherical, the spermathecae are relatively larger, and in males the tibia is slightly longer than the cymbium, though their length ratio does not exceed 1.5.[5]
