Cosmophasis ombria is a species of jumping spider in the family Salticidae. It was originally described as Maevia ombria by Tamerlan Thorell in 1877.[1]
Taxonomy
The species was originally described by Thorell in 1877 as Maevia ombria based on a male specimen from Kendari, Sulawesi.[2] Thorell later described Maevia marxii in 1890, which was subsequently treated as a synonym.[3]
The species was transferred to the genus Cosmophasis and treated as C. marxi by Prószyński in 1984.[4] However, Żabka and Waldock reinstated the original name C. ombria in 2012, removing it from synonymy with Cosmophasis viridifasciata and establishing C. marxi as a junior synonym.[5]
Distribution
C. ombria is distributed across Indonesia, including Sumatra, Java, Sulawesi, and the Krakatau Islands, with records also from Hainan in southern China.[1][5] The species has been collected from various locations in the Krakatau Islands, including Anak Krakatau, Pulau Krakatau Kecil (Panjang), and Pulau Sertung.[5]
Description
Males have a cephalothorax covered in pearly scale-hairs that are more numerous on the sides and anterior to the eye-field, which has a metallic shine.[5] The eye-field is dark brown with black eye surroundings, and there is a fringe above the anterior eyes. The abdomen is mottled brown, darkening posteriorly, with a light creamy belt around the anterior half and a cream central longitudinal stripe with paired spots on the sides.[5]
Females have a brown cephalothorax with a greyish-light brown eye-field containing numerous creamy scales and scattered brown bristles.[5] The thoracic area and sides are lighter and mottled orange with white scales. The abdomen is covered with brownish scale-hairs and displays a pattern of three yellow transverse stripes joining a central longitudinal stripe, with a wide yellow stripe bordering the anterior abdomen.[5]
The male palpal organ is characterized by a relatively small tegulum and a long, wavy embolus positioned at 9 o'clock.[5] Females have epigynal fossae without distinctive borders, divided by a wide median guide, with a strongly sclerotised posterior epigynal edge and elongate, L-shaped spermathecae.[5]
