Maxilla 1 (fig. 2 d) with first inner lobe or gnathobase bearing about 10 strong spines, small second inner lobe bearing ?3 setae and third inner lobe bearing 3 terminal setae. Outer lobe or coxal epipod bearing 8 long setae. Exopod with 9 marginal setae. Endopod 3-segmented bearing 4 setae medially. Fig. 2. Pseudodiaptomus hessei (Mrazek). a, antenna 2; b, divided seta from maxilliped; c, mandible; d, maxilla 1; e, maxilliped;/, maxilla 2. on the basal portion (second basal segment) and groups of 4 setae medially on segments 1 and 2 and approximately 7 terminal setae on segment 3. Maxilla 2 (fig. 2 /) with 5 large medial lobes or endites and 2 smaller terminal lobes each bearing 3 or 4 setae. Distal portion indistinctly segmented. Maxilliped (fig. 2 e) 6-segmented, 2 basal segments large, 4 distal segments small and decreasing in size distally. First segment with 3 medial lobes bearing 2 setae, 3 setae and 2 setae and a spine respectively. There are short fine hairs medially and tiny hooked spinules on the third lobe. Second segment expanded medially with 3 setae and a fringe of short fine hairs on the medial margin. Third segment bearing 2 + 3 setae, fourth segment 2 setae, fifth segment 2 setae, sixth segment 2 setae medially and 6 on an outer lobe. Among the setae on segments 3, 4 and 5 are four with a peculiar branched structure. These. Please note that these images are extracted from scanned page ima
