Corythalia blanda (♂,♀) (PECKHAM & PECKHAM, 1901)

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 distinct. base of RTA not or not distinctly wider than distal section. RTA in ventral view slim. RTA long. RTA in retrolateral view more or less parallel with longitudinal axis of palp. Tibia - ventral bump - sizeshort (between 0.5x and 0.8x the width of sperm duct). Tibia - ventral bump - characteristicsmoderately conspicuous. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum narrower than cymbium. Shape of proximal halfproximal tegulum lobe present. Proximal lobe - size rel.medium-sized. Proximal lobe - shaperegularly rounded. Special structureswith (fine) transversal ridge (often at distal half at the area of the border between embolic division and tegulum). Sperm duct - locationoccupying more than retrolateral 3/4 of tegulum. Sperm duct - shapedouble-stacked S-shaped, with proximal loop larger than others. 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 point6 o´clock-position. 7 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 - subdistallyat most 2x 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. long. with more than 1/2 winding but less than 3/4 winding. with distinct embolic lamella (longitudinally associated hyaline membrane (homologous to conductor?), 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). Special structuresickle-shaped. distally pointed. 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. Opisthosoma: Colourationthree bands; AM broadest; C second broadest (but only slightly narrower than AM), without dark chevron; PM narrowest. Distribution: Geographical DistributionSouth America.

FEMALE

Body: MarkingsOpistosoma with dark or bright spots . basic colouring dark. Eyes: AERdorsal edge recurve. Labium: Lengthlonger than wide. Legs: Leg formula4-3-1-2. 4-3-2-1. Colourationdark red-brown or brown with several lighter annulations, mainly at proximal articles and tarsi, but also at distal sections of tibiae and/or metatarsi. Opisthosoma: Colourationthree bands; AM broadest; C second broadest, with dark chevron; PM narrowest. Epigyne: Field - presencepresent. Field - widthbroader than long. Window - shape(approximately) round (length / width < 1.1). without transversal division. anterior 1/3 of epigynal window more or less as broad as posterior 1/3. Windows - septum - statecontinuous. very broad (> 2/3 the width of epigynal window). at anteriormost section clearly diverging. Window - posterior margin - distance to EpGF short.
