Corythalia circumflexa (♀) (MELLO-LEITÃO, 1939)

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

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. Window - shapeoval. Windows - septum - statecontinuous. medium-sized (> 1/6, < 1/3 the width of epigynal window). at anteriormost section clearly diverging. Window - posterior margin - distance to EpGF medium-sized (> 1/3 the length of epigynal window; < 1/2). 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 - shapemedially with relatively steep and long increase (medio-)anteriorly, leaving a distinctly large, approximately triangular field between them and the epigastric furrow. Copulatory opening - locationlocated centrally or more or less centrally in epigyne. Vulva: blind sac - lengthblind sac absent. fertilization duct - arising pointcentro-anteriorly. fertilization duct - widthinitial section of fertilisation duct narrow. primary spermatheca - shaperound. primary spermatheca - size rel.medium-sized (diameter of primary spermatheca more than 1/2 the length of epigynal window, but less than 2/3). primary spermatheca - position(main parts) posterior of secondary spermatheca (in dorsal view without gap between the two; may touching each other). secondary spermatheca - presencepresent. secondary spermatheca - shapelongitudinally oval. secondary spermatheca - size rel. very small (ratio "diameter primary spermatheca / diameter secondary spermatheca" > 2.5). secondary spermatheca - spanspan over both secondary spermathecae longer than span over both primary spermathecae. secondary spermatheca - orientationlongitudinal (posterio-anteriorly; with spermathecal head orientated posteriorly). connective duct - initial positionanterio-medially. connective duct - widthbroad (width of secondary spermatheca / width of connective duct < 2.5, but > 2). connective duct - final positionventro-medially. connective duct - length rel.medium-sized (length of connective duct / width of primary spermatheca > or equal 1.25, but < 1.5). head of spermatheca - shaperound (or at least spherical) (length > or equal 1 x width, but < 1.25x). head of spermatheca - orientationstraight posterior. Distribution: Geographical DistributionSouth America.
