Key to the genus Coronarachne gen. nov.
1 Males .............................................................................................. 2
− Females............................................................................................. 6
2 Palp in retrolateral view with two distinct RTAs, with the dorsal RTA with several denticles along its distal margin (e.g. Fig. 75 View FIGURES 74–78 )................................................................................................. 3
− Palp in retrolateral view without a dorsal RTA, but several isolated denticles on the dorsal surface of the palpal tibia ( Fig. 82 View FIGURES 79–84 )................................................................................... C. penicillus sp. nov.
3 Base of dorsal RTA close to middle of dorsal length of tibia; embolus not visible basally, fully enclosed in conductor, with tips of both structures fine and hair-like ( Figs 79, 80 View FIGURES 79–84 )............................................ C. neethlingi sp. nov.
− Dorsal RTA originating terminally, at distal end of tibia (e.g. Fig. 75 View FIGURES 74–78 ); embolus and conductor clearly separated, broader and not hair-like............................................................................................. 4
4 Ventral side of cymbium with cluster of distinct flattened setae at end of cymbial excavation; tegulum with distinct prolateral tegular apophysis distally; embolus somewhat S-shaped or looping, with the tip directed distally ( Figs 86 View FIGURES 86–89 , 90 View FIGURES 90–93 )............ 5
− Ventral side of cymbium without cluster of distinct flattened setae at end of cymbial excavation; tegulum without a prolateral apophysis; embolus forming an almost transverse broad coil, with the tip directed retrodistally ( Fig. 74 View FIGURES 74–78 )................................................................................................... C. denticulata sp. nov.
5 Tegulum with large subtriangular apophysis prolaterally, distal end close to tip of embolus; embolus somewhat S-shaped, basal coil about ⅓ the width of tegulum ( Fig. 86 View FIGURES 86–89 ).................................................... C. setosa sp. nov.
− Tegular apophysis smaller, subrectangular, protruding only slightly beyond distal tegular margin, distal end distant from embolus tip; conductor strongly developed, broader than embolus, with spur-like tip ( Fig. 90 View FIGURES 90–93 ).......... C. unigena sp. nov.
6 ST I consisting of a single oval lobe; copulatory openings oblique, slit-like, close to middle of epigynal plate ( Fig. 83 View FIGURES 79–84 )......................................................................................... C. penicillus sp. nov.
− ST I clearly bilobed, visible through integument ( Figs 76 View FIGURES 74–78 , 88 View FIGURES 86–89 , 92 View FIGURES 90–93 )............................................... 7
7 ST I clearly separated from the copulatory openings and copulatory ducts, by approximately double the length of the ST I ( Fig. 88 View FIGURES 86–89 ).................................................................................... C. setosa sp. nov.
− ST I situated close to copulatory openings and copulatory ducts, separated by less than their length ( Figs 76 View FIGURES 74–78 , 92 View FIGURES 90–93 ).......... 8
8 Copulatory openings small, situated close to anterior of epigyne; copulatory ducts consisting of three tight coils, leading to small oval anterior ST II ( Fig. 76 View FIGURES 74–78 )....................................................... C. denticulata sp. nov.
− Copulatory openings hook-shaped, situated close to centre of epigyne; copulatory ducts short, leading to bilobed ST II ( Fig. 92 View FIGURES 90–93 ).................................................................................. C. unigena sp. nov.
