– Apical process (x) of posterior gonopod always completely sclerotized ( Fig. 55M View Figure 55 ). Sternite of anterior gonopod rectangular ( Fig. 56D View Figure 56 ), if triangular then not slender ( Fig. 55L View Figure 55 ) ................................................................................ 6
5 Central part of collum and anterior half of telson dark grey ( Figs 53B View Figure 53 , 57A View Figure 57 ). Retrorse process of anterior gonopod laterally not protruding above telopodite margin ( Fig. 57G View Figure 57 ). Telopodite of posterior gonopod without a membranous lobe ( Figs 57F, H View Figure 57 ).................................................. H. griseus View in CoL sp. n.
– Collum and telson shiny white ( Figs 53C View Figure 53 , 58A View Figure 58 ). Retrorse process of anterior gonopods laterally slightly protruding above telopodite margin ( Fig. 58F View Figure 58 ). Telopodite of posterior gonopod with a membranous lobe (y in Figs 58E, G View Figure 58 )............................................................................... H. albicollaris View in CoL sp. n.
6 Lateral margin (w) of posterior gonopod apically with a thick, swollen, wellrounded projection ( Figs 55M View Figure 55 , 60E View Figure 60 ). Apical process (x) basally wide, apically extended into a slender projection ( Fig. 55M View Figure 55 )............................................ 7
– Lateral margin of posterior gonopod without a swollen projection ( Figs 56E View Figure 56 , 59E, w View Figure 59 ). Apical process (x) either wide ( Fig. 56E View Figure 56 ) or slender ( Fig. 59E View Figure 59 ) ..... 8
7 Collum in anterior half entirely red or white ( Figs 53A View Figure 53 , 55A View Figure 55 ). Sternite of anterior gonopods wide, triangular ( Fig. 55L View Figure 55 ). Retrorse process of anterior gonopod laterally not protruding above telopodite ( Fig. 55N View Figure 55 ). Apical process (x) of posterior gonopod basally with a protruding margin ( Fig. 55M View Figure 55 )......... .......................................................................... H. brachiosauroides View in CoL sp. n.
– Collum grey, only at margins white ( Fig. 60A View Figure 60 ). Sternite of anterior gonopods wide and well-rounded ( Fig. 60D View Figure 60 ). Retrorse process of anterior gonopod laterally widely protruding above telopodite ( Fig. 60F View Figure 60 ). Apical process (x) of posterior gonopod basally wide, but not protruding ( Fig. 60E View Figure 60 ).................... ..................................................................................... H. montanus View in CoL sp. n.
8 Apical process (x) of posterior gonopod wide ( Figs 56E View Figure 56 , 63B View Figure 63 ). Retrorse process of anterior gonopod slightly protruding above telopodite lateral margin ( Fig. 56F View Figure 56 )................................................................................................... 9
