Corythalia obsoleta (♂,♀) BANKS, 1929

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 very slim. RTA long. Tegulum: Widthtegulum as broad as cymbium. Shape of proximal halfproximal tegulum lobe as such absent. Proximal lobe - positionat retrolateral half of tegulum. Proximal lobe - size rel.relatively narrow. Proximal lobe - shaperegularly rounded. Special structureswithout special structures. 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. Arising point5 o´clock-position. 6 o´clock-position. 7 o´clock-position. General structurewith more than 3 longitudinal ridges. long. with less than 1/2 winding. without distinct embolic lamella over entire embolus length. without apophysis. in ventral view subdistally distinctly narrower than proximally. narrow to medium-sized and hose shaped. Special structuresubdistally broadened. sickle-shaped. distally pointed. tip bent proximo-ventrally. with membranous lamella subdistally or distally. Legs: Leg formula3-4-1-2. Colourationcompletely or mainly with dark colour (e.g. dark red-brown) ((hardly with lighter sections, e.g. only tarsi lighter). Distribution: Geographical DistributionNorth America.

FEMALE

Body: MarkingsOpistosoma with dark or bright spots . basic colouring dark. Eyes: AERdorsal edge recurve. Labium: Lengthlonger than wide. Legs: Leg formula3-4-1-2. Colourationcompletely or mainly with dark colour (e.g. dark red-brown) ((hardly with lighter sections, e.g. only tarsi lighter). Epigyne: Field - presencepresent. Field - widthbroader than long. Window - shapeoval. Windows - septum - statecontinuous. very narrow. separating more than only the posterior sections of epigynal windows. at anteriormost section rather converging than diverging. Window - posterior margin - distance to EpGF short. Window - posterior margin - positionnot reaching the epigastric furrow. Window - lateral margin - conditioncontinuous. Window - anterior margin - conditionmargins of both epigynal windows anterio-medially not connected. Window - posterior half - shaperegularly rounded. Copulatory opening - locationlocated in anterior half of epigyne. Vulva: fertilization duct - widthinitial section of fertilisation duct narrow. primary spermatheca - shaperound. secondary spermatheca - presencepresent. secondary spermatheca - shapedrop-shaped. secondary spermatheca - visibilityvisible through cuticle of the epigyne. secondary spermatheca - size rel. medium-sized. secondary spermatheca - spanspan over both secondary spermathecae shorter than span over both primary spermathecae. secondary spermatheca - orientationtransversally (medio-laterally; with spermathecal head orientated medio-posteriorly). connective duct - initial positioncentro-medially. connective duct - widthvery narrow. connective duct - final positionventro-medially. connective duct - shapemainly straight longitudinally, but initially curved. connective duct - length rel.short. head of spermatheca - shapeflat.
