Maxillopoda - Lepadiformes - Stramentidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|D. E. Hattin 1977||Capitulum and peduncle typical
for family, comprising 10 plates and 8 columns,
respectively. Scutum trapezoidal, with
upper lateral margin forming obtuse angle
with base and lower part of occludent margin
forming acute angle with base. Scutal umbo
lies at position of angulation of occludent margin;
lies a little more than one-third distance
from scutal apex to rostral angle of scutum.
Occludent margin of capitulum strongly inflected
in largest known (type) specimen, less
inflected in smaller specimens. Upper latus
broadly triangular. Carinobasal angle of carinal latus strongly obtuse. Peduncle joins capitulum
with strong obliquity, has up to four
more plates in carinal lateral column than in
scutal column. Peduncle widest at summit,
margins convex, with plates in paired columns
usually more than three times wider than high.
