Corythalia ricti (♂) BAYER, 2020

In addition to the genus diagnosis, the following features characterize the species:

MALE

Body: MarkingsOpistosoma with dark or bright spots . basic colouring dark. Carapace: ColourationLaterally with light bands. Eyes: AERdorsal edge recurve. Labium: Lengthlonger than wide. Palp: GnathocoxaCorner present. Tibia - retrolateral tibial apophysis - characteristicsdorsal serration distinct. base of RTA distinctly wider than distal section (consider also retrolateral view). RTA in ventral view medium-sized in width (between 3x longer than broad and 4.5x). RTA medium-sized in length. RTA in retrolateral view with clear ventral orientation (at least 10° angle). RTA in retrolateral view with bent (distal section at least with 70° bent from longitudinal axis of proximal section). Tibia - ventral bump - sizevery short and indistinct. Tibia - ventral bump - characteristicsinconspicuous. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum narrower than cymbium. Shape of proximal halfproximal tegulum lobe present. Proximal lobe - positionstill retrolaterally, but slightly shifted centrally. Proximal lobe - size rel.relatively narrow. Proximal lobe - shapeprolaterally with very flat extension. Special structureswith (fine) transversal ridge (often at distal half at the area of the border between embolic division and tegulum). Sperm duct - locationoccupying clearly more than retrolateral half and at most 3/4. Sperm duct - shapedouble-stacked S-shaped, with proximal loop smaller than distal. Embolus: Base positioncentro-distally (or even retrolatero-distally). Base circle sizelarge (width between 2/3 and 3/4 the width of tegulum). Base - special structureswith prolateral extension in form of an elongated bulge. Arising point4 o´clock-position. 5 o´clock-position. 6 o´clock-position. Direction of distalmost sectiondisto-prolaterally to prolaterally (with at least 51° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyfrom 2.1x to 2.5x broader. from 2.6x to 4x broader. width relation - subdistally - centrallyfrom > 1/4 to < 1/2 the width of central section. Shapecircular curved. bent counterclockwise. General structurewithout or with 1-3 (at most) longitudinal ridges. short, between 1/3 and 1/2 the width of tegulum. medium-sized, between 1/2 and 1x the width of tegulum. with less than 1/2 winding. with more than 1/2 winding but less than 3/4 winding. without distinct embolic lamella over entire embolus length. without apophysis. in ventral view subdistally not narrower or narrower, but not distinctly narrower than proximally (more than 1/7 as broad. narrow (centrally between 1/4 and 1/3 the width of sperm duct). narrow to medium-sized and hose shaped. Special structuresickle-shaped. distally pointed. tip bent proximo-ventrally. without apohysis (apophyses). Legs: Leg formula3-4-2-1. 4-3-2-1. Colourationdark red-brown or brown with few lighter annulations, mainly at proximal articles and tarsi. completely or mainly with dark colour (e.g. dark red-brown) ((hardly with lighter sections, e.g. only tarsi lighter). Opisthosoma: Colourationthree bands; AM broadest; C second broadest (but only slightly narrower than AM), without dark chevron; PM narrowest. Distribution: Geographical DistributionSouth America.
