Corythalia ursina (♂) (MELLO-LEITÃO, 1940)

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

MALE

Body: MarkingsOpistosoma with dark or bright spots . basic colouring dark. Eyes: AERdorsal edge recurve. Labium: Lengthlonger than wide. Palp: Tibia - retrolateral tibial apophysis - characteristicsdorsal serration indistinct but present. base of RTA not or not distinctly wider than distal section. 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 more or less parallel with longitudinal axis of palp. RTA in retrolateral view without bent (or just indistinct bent). Tibia - ventral bump - sizeabsent or at least not recognisable as such. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum narrower than cymbium. Shape of proximal halfproximal tegulum lobe present. proximal tegulum lobe as such absent. Proximal lobe - positionat retrolateral half of tegulum. Proximal lobe - size rel.broad. Proximal lobe - shaperegularly rounded. Special structureswithout special structures. Sperm duct - locationoccupying clearly more than retrolateral half and at most 3/4. occupying more than retrolateral 3/4 of tegulum. Sperm duct - shapeshape not recognisable, as only parts of sperm duct visible through tegulum surface. Embolus: Base positionin prolateral half (or, depending on the size, prolateral 2/3, 3/4, etc.) of tegulum, but not reaching the prolateral margin; at distal section. Base circle sizemedium-sized. large (width between 2/3 and 3/4 the width of tegulum). Base - special structuresSpecial structures at/ on embolus base absent (except for indistinct ridges or flat bulges that are often recognisable). Arising point6 o´clock-position. 7 o´clock-position. Direction of distalmost sectionprolatero-distally (with between 11° and 50° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyfrom 4.1x to 7.5x broader. width relation - subdistally - centrallyfrom > 1/2 to < 3/4 the width of central section. General structurewith more than 3 longitudinal ridges. medium-sized, between 1/2 and 1x the width of tegulum. 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 distinctly narrower than proximally. quite broad and hose-shaped. massive (centrally almost as broad or broader than width of sperm duct). Special structureS-shaped. sickle-shaped. distally rounded. without apohysis (apophyses). Distribution: Geographical DistributionSouth America.
