Key to the Tasman Sea species of the microps View in CoL -group

1 Telson with lateral spiniform setae only in posterior part ( Figs 1C View Figure 1 , 9C View Figure 9 , 13C View Figure 13 ). Uropodal endopod with medial spiniform setae set distantly apart from each other ( Figs 1D View Figure 1 , 9E View Figure 9 , 13E View Figure 13 ) ............................................................. 2

—— Telson with lateral spiniform setae along entire or nearly entire margins ( Fig. 5C View Figure 5 ). Uropodal endopod with spiniform setae set close to each other ( Fig. 5E View Figure 5 ) ................................................................... H. (H.) keablei sp. nov.

2 Telson cleft spinules along entire cleft length ( Figs 1C View Figure 1 , 13C View Figure 13 ). Pereopod 1 carpopropodus, segment 1 with bifurcated distomedial spiniform setae ( Figs 2F,G View Figure 2 , 14H,J View Figure 14 ) ................................................................................ 3

—— Telson cleft spinules only in anterior part (0.1−0.7 of cleft length) ( Fig. 9C,D View Figure 9 ). Pereopod 1 carpopropodus, segment 1 with normal, non-bifurcated distomedial spiniform setae ( Fig. 10G View Figure 10 ) ....................................................................................................... H. (H.) macropsis View in CoL

3 Telson with rather deep cleft, about 0.3 of telson length ( Fig. 1C View Figure 1 ). Telson lateral margins with six to eleven spiniform setae. Eyes with distomedial rim ( Fig. 1A,B View Figure 1 ). Pereopod 3−6 unguis rather short and thick ( Fig. 3 View Figure 3 A−C). Uropodal endopod with two to five proximal spiniform setae ( Fig. 1D View Figure 1 ) ..................................................... H. (H.) communis View in CoL

—— Telson with rather shallow cleft, about 0.14−0.15 of telson length ( Fig. 13C View Figure 13 ). Telson lateral margins with 13 to 20 spiniform setae. Eyes without distomedial rim ( Fig. 13B View Figure 13 ). Pereopod 3−6 unguis rather long and thin ( Fig. 15C,D View Figure 15 ). Uropodal endopod with 8 to 16 spiniform setae along almost entire length ( Fig. 13E View Figure 13 ) .................................................................................. H.
