Capitulum: Length of capitulum from tips of palpi to tips of cornua is about
0.31 mm; width of basis is 0.22
0.25 mm. Cornua are moderate and pointed.
Palpal article II is strongly salient laterally and longer than article III. Article III is
without dorsal spur. Palpal article II is with a blunt retrograde spur at the ventrolat-
eral angle. Article III has a very short, pointed retrograde spur. Dentition in 4/4 pat-
tern, with seven or eight denticles in each file.
Scutum: Length of scutum from tips of scapulae to posterior margin ranges
from 1.09 to 1.33 mm. Lateral grooves well defined and enclosing one festoon on
each side. Cervical grooves are short and inconspicuous. Punctations are coarse
and deep, and evenly distributed. Festoons are longer than broad.
Legs: A moderate spur on coxa I; spurs are progressively shorter on II, III, and IV.
All trochanters have short, pointed ventral spurs, which diminish in size from I to IV.
