description: 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)................................................................................................. 3
− Palp in retrolateral view without a dorsal RTA, but several isolated denticles on the dorsal surface of the palpal tibia (Fig. 82)................................................................................... 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)............................................ C. neethlingi sp. nov.
− Dorsal RTA originating terminally, at distal end of tibia (e.g. Fig. 75); 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, 90)............ 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)................................................................................................... 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).................................................... 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).......... 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)......................................................................................... C. penicillus sp. nov.
− ST I clearly bilobed, visible through integument (Figs 76, 88, 92)............................................... 7
7 ST I clearly separated from the copulatory openings and copulatory ducts, by approximately double the length of the ST I (Fig. 88).................................................................................... C. setosa sp. nov.
− ST I situated close to copulatory openings and copulatory ducts, separated by less than their length (Figs 76, 92).......... 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)....................................................... C. denticulata sp. nov.
− Copulatory openings hook-shaped, situated close to centre of epigyne; copulatory ducts short, leading to bilobed ST II (Fig. 92).................................................................................. C. unigena sp. nov.
