Genus Ciplakastacus gen. nov.

Diagnosis

Leptastacidae . Integument smooth. Hyaline frills of abdominal somites well developed, consisting of rectangular lappets. Anal opening flanked by conspicuous serrate extensions. Caudal ramus long, with distal outer corner acutely produced posteriorly; seta I very long, flanked by two elongate spinules; setae III and VI vestigial. Sexual dimorphism in antennule, P5, P6, abdominal spinulation and genital segmentation.

Rostrum triangular. Antennule with very long segment 2; seven-segmented in ♀, with aesthetasc on segment 4 and as part of apical acrothek on segment 7; haplocer and nine-segmented in „, with geniculation between segments 7 and 8 and aesthetascs on segment 5 and as part of apical acrothek on segment 9. Antenna with basis and proximal endopod segment completely fused forming allobasis; exopod with one lateral and two distal setae. Labrum with few long spinules medially; without frontal spinous process; not distinctly trilobate. Mandibular palp two-segmented; basis with one seta, endopod with one lateral and four apical setae. Maxillule with endopod and exopod represented by three and two setae, respectively; arthrite only slightly rotated relative to coxa and basis. Maxilla with two welldeveloped cylindrical endites on syncoxa; endopod short. Maxilliped with seta on syncoxa; accessory seta of endopod reduced.

P1 basis with both outer and inner seta. P1 exopod three-segmented; exp-3 with four setae/spines. P1 endopod three-segmented; enp-2 without seta; enp-3 with one vestigial and two geniculate setae; not prehensile. P2–P4 bases with outer seta; endopods two-segmented; outer distal element of enp-2 fused to segment. Armature formulae for P1–P4 are shown in Table 2.

P5 with baseoendopod and exopod forming a common plate in both sexes; in ♀ with six setae and two spines; in „ with five setae and two spines. Sixth pair of legs asymmetrical in „, with three setae each; represented by opercula closing off gonopores in ♀, with three setae each.

Type and only species. Ciplakastacus mersinensis sp. nov.
