Notes
The most recent previous generic diagnosis for Mastigoniscus provided by Brökeland and Brandt (2006), page 86, contains several characters that do not apply to M. latus ( Birstein, 1971) , M. microcephalus (Gamó, 1989) and M. minimus Wenz, Knauber & Riehl , sp. nov. from the northwest Pacific Ocean. Character states listed by Brökeland and Brandt (2006) applying only to the remaining species of Mastigoniscus are: posterior body part (pereonites 5–7 and pleotelson) length exceeding length of anterior part; pleotelson posterolateral processes strongly projecting in males, shorter in females; pereopod VI carpus distodorsally with spine-like setae.
The similarities of M. latus , M. microcephalus and M. minimus Wenz, Knauber & Riehl , sp. nov., as well as the geographic proximity of their occurrence, can be interpreted as evidence for a shared recent ancestry and may justify further studies on their relationships with the remaining species of Mastigoniscus . However, whether the observed similarities are chance similarities or justify the appraisal of a separate genus-level taxon or subgroup within Mastigoniscus requires a thorough systematic analysis, preferably including a broader genetic representation of Mastigoniscus .
Diagnosis
Head without rostral process; pereonites 5–7 and pleotelson tergites medially fused, sutures more or less distinct; pereonite 7 reduced in adults, short, with fully developed pereopods 7; antenna 2 article 3 dorsal projection distal margin serrated; male pleopods 1 and 2 large, covering most of the pleotelson ventral surface, pleopod 2 endopod elongate, article 1 curved backwards, article 2 much longer than article 1, forming slender copulatory filament; female operculum relatively smaller in relation to pleotelson than male operculum.
