Paralimnadia wolterecki ( Brehm, 1933) New

Combination

= Eulimnadia wolterecki ( Brehm, 1933)

= Limnadia wolterecki Brehm, 1933

Comments: Celebes. Reported only once. Based on the drawings by Brehm (1933), this species appears to have the morphological characteristics of Paralimnadia .

Diagnosis: (From Schwentner et al. 2020a). Cephalic fornices extending anteriorly to rostral apex. Rostrum variable, blunt to acute, long or short, generally triangular to subquadrate in lateral view. Rostrum with or without an apical spine. Compound eyes fused medially, sometimes projecting in smoothly arcuate ocular tubercle. Frontal organ sessile. Occipital notch present. Carapace thick, generally rounded. Carapace dorsal margin smooth, lacking carinae, hinge line straight. Carapace with or without pigmentation, growth lines obvious, projecting. Umbone present, projecting well above hinge line. Muscle scar rarely visible. Male first two thoracopods with endopod (sensu Olesen, 2007) lacking an apical suctorial organ or modified tactile setae. If modified setae or spines are present these are never arranged in a transverse apical row of spatulate spines. Telson without a ventroposterior, posteriorly directed spiniform projection. Eggs 110– 170 μm in diameter, spherical and generally lacking ornamentation.

Comments: Two genera are recognised here. Daday (1913a: 14) designated Cyzicus as the type genus. Novojilov (1954) created Bairdestheriidae for a large number of fossil genera, among which were Opsipolygrapta and Pseudograpta , and then moved several recent cyzicid species into these genera based on their descriptions. However, the relationships are at best dubious, and no subsequent authors have followed this arrangement.
