Genus Tylogonus Simon, 1902

Diagnosis. Medium sized spiders usually found on foliage. Body form and color pattern more like dendryphantine jumping spiders. Most species greenish with iridescent scales. Male abdomen usually with white anterior margin and paired large white spots. Male chelicera modified, with front spur and concaved internal margin. Chelicera with two promarginal teeth and one retromarginal tooth. Embolus of male palp fixed and uncoiled. Epigynum without distinct window structure, but usually with small posterior depressions. Vulva anterior to the depressions. Like typical euophryines, male palp has a retrolateral sperm duct loop, but differs from other euophryine genera in the concaved internal margin and the presence of a spur on the front surface of the male chelicera, the fixed and uncoiled embolus of the male palp, and the absence of epigynal window.

Remarks. Nine species have been reported from the Central and South America ( Platnick 2012). Two new species from Ecuador are described here.
