Dendrocephalinus

Diagnosis (Updated from Rogers 2006) Fully extended gonopods extending to third or base of fourth abdominal segment. Gonopod basal portion chitinised, rigid, subcylindrical, bearing a single ventromedial tubercle. Gonopod distal eversible portion soft, distal third expanded, comb plate lacking, distal half with four longitudinal rows of short spines, each row evenly spaced around gonopod. Brood pouch expanded proximally, distal portion either narrowing abruptly to posteriorly directed subcylindrical tube, extending to base of fourth to eighth abdominal segment, or absent. Male abdomen first two or three segments with ventrolateral spiniform projections. Male first thoracopods unmodified. Nearctic (USA, Mexico (? )). All species occur within the Coastal Plain anostracan biogeographic region (Rogers, 2014 a).

Remarks We suspect that this taxon may actually represent an independent genus, however molecular analyses will be required to demonstrate this. At this time we choose to conservatively maintain the taxon as a subgenus.
