Description.
Tree to 25 m tall, the young branches sparsely puberulous, not conspicuously lenticellate. Leaves with lanceolate stipules to 2 mm long, caducous, adnate to
base
of petiole; petioles 2-3 mm long, terete, tomentellous when young; lamina elliptic, coriaceous, 3-7
x
1.5-3.5 cm, cuneate at base, acuminate at apex, the acumen 3-6 mm long, glabrous above, densely brown-tomentellous beneath; midrib plane above, prominent beneath; veins 6-7 pairs, plane above, prominulous beneath. Inflorescence of terminal and subterminal panicles of racemes, the rachis and branches yellow-brown tomentose. Bracts and bracteoles lanceolate to triangular, 1-2 mm long, tomentose, caducous. Flowers almost sessile on primary inflorescence branches. Receptacle turbinate, tomentose on exterior, densely tomentose--pilose within, constricted at base to a minute pedicel 0.5 mm long; calyx lobes 5, acute, triangular, tomentose on exterior, sparsely tomentose within. Petals absent. Stamens 5-6, inserted opposite four calyx lobes. Style basal, pubescent for
3/4
of length; ovary rufous tomentose. Fruit pyriform, 2-2.5
x
1 cm, exterior densely rufous-brown tomentose.

This species falls into subgenus
Licania
section
Licania
and it is close to
Licania harlingii
Prance but differs in the smaller more coriaceous leaves (3-7
x
1.5-3.5 vs 7-12
x
3-7 cm), fewer veins (6-7 vs 8-11) and the shorter leaf acumen. The habitat is noted as primary forest. This is named for Abel Monteagudo, the collector of the types of two of the species described here.
Since two of these new species and the recently described
Licania condoriensis
Prance (2013)
from the borders of Peru and Ecuador all belong to subgenus
Licania
section
Licania
I have provided a key based mainly on vegetative characters to all species of the section known to occur in Peru. All other species of
Licania
from Peru fall into other subgenera and sections of
Licania
of
Prance and Sothers (2003a)
. They differ from
Licania apiknae
,
Licania condoriensis
and
Licania monteagudensis
in one or more of the following characters:
Stamens 10-50, exserted (Subgenus
Moquilea
)
Petals present
Leaf undersurface with a furfuraceous pulverulent pubescence (Section
Pulverulenta
)
Inflorescence a panicle of cymules (Section
Cymosa
)
Leaf undersurface glabrous or with a hirsute pubescence (Sections
Hymenopus
and
Hirsuta
)
