Genus Corythalia C.L. Koch, 1850
Diagnosis: Corythalia is distinguished from all other salticid genera by the following characters in combination:
Cheliceral fangs very short, retromargin of cheliceral furrow with one very small and slim tooth, promargin either with one tooth or, more rarely, with two teeth located very close together or even connected with each other. Anterior surface of cheliceral base medio-distally with a small lobe with several hairs. In dorsal view carapace anteriorly not broader than centrally. Anterior lateral eyes in frontal view clearly located further dorsally than anterior median eyes. Carapace at proximo-lateral margins usually with broad bands of light scale hairs. Opisthosoma dark brown with at least one light and usually broad transverse band, only rarely narrow and/or interrupted medially; most species with three light transverse bands on abdomen.
Males with long dark fringe of hairs on tibiae and metatarsi of walking legs III, often similarly well developed on legs I–II. Embolus coiled, at least at its disc-shaped base. Tegulum proximally extending beyond proximal margin of cymbium and partly covering palpal tibia, generally in form of a proximal lobe (at retrolateral section). Male palpal tibia ventrally usually with a bump. Distal haematodocha developed. RTA mostly with dorsal serration.
Female epigyne with epigynal windows, separated by a longitudinal septum. In general, vulva with primary and secondary spermathecae (the former mostly larger than the latter), both connected by a narrow and long duct, often longer than diameter of primary spermathecae.
