Fig. 30 SEM micrographs. Applanola hirsuta (Thompson & A. Scott, 1903) comb. nov. ( 9). A, Cephalothorax and rostrum, frontal [anterodorsal pore 

 arrowed]; B, cephalothorax, ventral [anteroventral pore arrowed]; C, anal opening and caudal ramus, ventral [ventral pore arrowed]; D, right caudal 

 ramus, ventral, showing cup-shaped pore. [Scale bars: 6 um (D), 15 um (C), 20 um (B), 60 urn (A)]. 



Genus Troglophonte gen. nov. 



Diagnosis. Laophontidae. Body shape unknown but somites not 

 well demarcated. Rostrum short, presumably fused at base. 

 Integumental cup-shaped pores unconfirmed. Anal operculum 

 spinulose. Caudal rami short, squarish. 



Sexual dimorphism in antennule, P3 endopod, P5, P6 and in 



genital segmentation. 



Antennules 7-segmented in $, segmentation unknown in S. An- 

 tenna with 4 setae on exopod; allobasis with abexopodal seta. 

 Mouthparts unknown. Maxilliped very slender. 



PI with 3-segmented exopod bearing 4 setae on exp-3 and slender 

 endopod; enp-1 without inner seta, enp-2 with minute seta and 

 slender, strong claw. P2-P4 with 3-segmented exopods and 2-seg
