Corythalia metallica (♂) (PECKHAM & PECKHAM, 1893)

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 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 - sizelong (at least 1.5x as long as width of sperm duct, sometimes extending beyond lateral margin of tibia in ventral view). Tibia - ventral bump - characteristicsconspicuous. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum narrower than cymbium. tegulum as broad as 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 structureswith (fine) transversal ridge (often at distal half at the area of the border between embolic division and tegulum). Sperm duct - locationoccupying clearly more than retrolateral half and at most 3/4. 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 sizelarge (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 point4 o´clock-position. 5 o´clock-position. 6 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 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. without apophysis. in ventral view subdistally not narrower or narrower, but not distinctly narrower than proximally (more than 1/7 as broad. narrow to medium-sized and hose shaped. Special structuredistally irregularly bifurcated. S-shaped. distally distinctly bent retrolaterally. tip bent retrolaterally (tip may be very fine and light). Legs: Leg formula3-4-1-2. 3-4-2-1. Colourationdark red-brown or brown with few lighter annulations, mainly at proximal articles and tarsi. Opisthosoma: Colourationthree bands; AM broadest; AM & C narrower (C < 1/6 OL), with light small stacked chevrons betw. C & PM . Distribution: Geographical DistributionNorth America.
