Species Falsilandrumius lobatus - Plate 1 of morphological figuresIssued from : G.O. Sars in Résult. Camp. Scient. Prince Albert I, 69, pls.1-127 (1924). [Pl.LI, figs.8-13]. As Scolecithrix lobata.
Female: 8, habitus (dorsal); 9, idem (lateral left side); 10, rostrum; 11, P1 (rami incomplete); 12, P2; 13, P5.

Nota Female:
- Rostrum small, with notched base and 2 long and slender filaments.
- head and 1st pedigerous segment fused, 4th and 5 th pedigerous segments more or less visible.
- Posterolateral corners of the 5th thoracic segment narrow tongue-like backward.
- Urosome short, about 1/3 of prosome length (69 : 22).
- Genital segment very swollen ventrally; the length longer than the two following segments together.
- Caudal rami not divergent and slightly longer than wide.
- A1 broken , probably large.
- P5 2-segmented, almost straight, directed obiquely outward; distal segment flat, widdened in the middle, with 4 spines, 2 apical and 2 lateral; the inner spine the strongest; the 2 apical spines of inequal lengths, the outer very small anfd tooth-like; the external spine very small and attached nearest of the base of segment.

Rem.: For Vyshkvartseva (2001, p.93) Scolecithricella lobata Sars (1920), Scolecithrix lobata Sars (1924), Amallothrix lobata Sars (1925) probably belons to Falsilandrumius, as the species agrees with this genus in the shape of the posterolateral corner of the thoracic segment 5 and rostrum, structure of P1 (basipod without inner distal seta, endopod without setose outer lobe), structure of P2 (outer distal corner of endopodal segments 1 and 2 produced as a spine-like process), and armament of its segments (posterior surface of exopodal segment 1 with spinules, of exopodal segments 2 and 3 without spinules; endopodal segment 2 with numerous long spinules, while in Amallothrix and Scolecithricella endopod and exopod of P2 with a few spinules; and in the shape and armament of P5 (3-segmented, distal segment longer than wide and slightly flattened, with 4 spines, inner spine the longest, subequal in length to the segment, outer spine situated closer to the segment base, not opposite the inner spine, as is typical of Amallothrix). But the generic position can be confirmed only after description of mouthparts and the male.
