Species Tortanus (Atortus) manadoensis - Plate 1 of morphological figuresIssued from: Mulyadi, S. Nishida & S. Ohtsuka in Crustaceana, 2017, 90 (1). [p.92, Fig.8].
Male (from 1°23.943'N, 125°07.162'E): a, habitus (dorsal); b, right A1 (number of ancestral segment indicated by Roman numerals); c, right P5; d, left P5.

Nota:
- Prosome about 3.1 times as long as urosome.
- Posterior corners of prosome produced into symmetrical, rounded lobes.
- Genital somite asymmetrical, produced postero-laterally on left side.
- Urosomite 2 without any lateral processes.
- Caudal rami asymmetrical, right ramus longer than left.
- Appendages as in male T. (A.) sulawesiensis, except right A1 and P5.
- P5: Right leg coxa short and swollen; basis expanded with triangular proximomedial process, medial margin produced medially into rounded process bearing long setule, posterior surface of segment with long setule; inner margin of exopod lamellar with leteral spinule at distal 1/3. Left leg coxa unarmed; basis elongated and straight with medial setule at mid-length; exopodal segment 1 curved medially with medial setule at mid-length; exopodal segment 2 curved medially with 3 semicircular processes along distal half of medial margin and stout serrated seta at tip, subterminal medial setule and midlateral and subdistolateral spinules.

Rem.: For Mulyadi & al. (2017, p.93), Tortanus (A.) manadoensis belongs to the recticauda species complex, and can be assigned to the murrayi species group by the characteristic processes on the basis and Re of the male right P5. Tortanus (A.) manadoensis is distinguished from the other species of the group by the triangular proximomedial process on the basis of the male right P5 and the semicircular processes on the Re2 of the male left P5.
