Corythalia insularis (♂) RUIZ, BRESCOVIT & FREITAS, 2007

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 indistinct but present. base of RTA not or not distinctly wider than distal section. RTA in ventral view slim. 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 slight ventral orientation (less than 10° angle). 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.medium-sized. Proximal lobe - shaperegularly rounded. Special structureswithout special structures. Sperm duct - locationoccupying clearly more than retrolateral half and at most 3/4. Sperm duct - shapedouble-stacked S-shaped, with proximal and distal loop equal in size. 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. Base - special structuresSpecial structures at/ on embolus base absent (except for indistinct ridges or flat bulges that are often recognisable). Arising point5 o´clock-position. 6 o´clock-position. Direction of distalmost sectiondistally to minimally prolatero-distally (not more than 10° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyfrom 2.1x to 2.5x broader. width relation - subdistally - centrallyfrom > 1/2 to < 3/4 the width of central section. General structurewithout or with 1-3 (at most) longitudinal ridges. medium-sized, between 1/2 and 1x the width of tegulum. with less than 1/2 winding. without distinct embolic lamella over entire embolus length. 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). Special structuresickle-shaped. without apohysis (apophyses). Legs: Colourationcompletely 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.
