Subtribe Plexippina

Plexippina is a subtribe of jumping spiders within the family Salticidae, subfamily Salticinae, and tribe Plexippini. The subtribe is widely distributed across tropical and subtropical regions, particularly in the Old World, with several species occurring in temperate areas and many adapted to human-modified environments. Members of Plexippina are commonly encountered on walls, buildings, tree trunks, fences, and vegetation in both natural and urban habitats.

Spiders of the subtribe Plexippina are generally medium to large-sized jumping spiders with a robust and compact body form. Coloration is often contrasting and patterned, featuring bands, spots, or patches of white, black, brown, or gray, and in some species subtle iridescent hues. The cephalothorax is relatively high and broad, and the abdomen is oval to elongate, often bearing distinctive markings that aid in species recognition.

Morphologically, Plexippina are distinguished by characteristic structures of the male palpal organs and the female epigyne, which are central to defining genera and species within the subtribe. Legs are strong and well developed, supporting powerful jumps and agile movement across open and vertical surfaces. Sexual dimorphism is common, with males frequently exhibiting more pronounced patterns or ornamentation.

Behaviorally, members of Plexippina are active, diurnal visual predators. They do not construct capture webs but hunt by stalking prey and capturing it with a rapid leap. Many species display bold and curious behavior, often readily approaching moving objects, including humans. Courtship behavior is visually driven and involves leg movements, body postures, and short display sequences.

Ecologically, Plexippina spiders are important predators of small insects and other arthropods and contribute to natural pest control in a wide range of ecosystems. The subtribe includes well-known and widespread genera such as Plexippus and Hyllus, making Plexippina one of the most familiar and adaptable lineages within the jumping spiders.
