Being about as wide as scapus
, the fastigium is wider than in most genera, but clearly narrower than in Eurycorypha and Monteiroa.
The female has a deep atrium in the epigynum with a long and folded scapus
and base of pedicellus yellow-orange, basal flagellomere and pedicellus apex blackish brown.
Without the suitable use of scapus
of pachymeter suggested by Mandarim-de-Lacerda (1995), to obtain the measures, Barros found significant difference from 6th day for LT and from 5th day for LA.
2.25x as long as maximally wide, 1.05x longer than first flagellomere.
yellow-brown, pedicellus yellow-brown basally, pale brown distally, basal flagellomere pale brown.
1.3 Obtain the measure considering the two points of insertion in each ear using the scapus
of the pachymeter to measure the external ends.
Antennae filiform, reaching fifth abdominal tergum, densely covered with short bristles; scapus
flattened basally, longer than pedicellus; third segment as long as scapus
Antenna as long as the head and the mesosoma combined; 16 antennomeres; scapus
2.0 times as long as wide apically; first flagellomere 3.2 as long as wide apically, second flagellomere 2.4 times and third 2.1 times as long as wide apically, further flagellomeres progressively shortening, 13th-15th subcubic (Figure 2).
Folia numerosa, vaginae distinctae, ellipticae, 7-10 cm longae, 4-5 cm latae; laminae anguste triangulari-lanceolatae, 37-55 cm longae, 1.3-1.7 cm latae, involutae, distaliter arcuatae; scapus
inflorescentiae erectus, teres, 29-50 cm longus; inflorescentia simplicissima; spica anguste elliptica, complanata, 18-25 cm longa, 3.5-4.5 cm lata; bracteae florales distichae, imbricatae, late ovatae, 5-5.5 cm longae, 4-4.5 cm latae, carinatae, supera virides, basalia incarnatae, nervatae; petala 7-8 cm longa, ca.
These values were obtained using the scapus
of a pachymeter, which is used for measure depth (Mandarim-de-Lacerda, 1995).
Antennae formed by three segments, each with a different morphological structure from other segments: scapus
oval in the dorsal view, more or less triangle-shaped in cross section; pedicellus minute, indistinct, and knob-shaped; third segment cylindrical, with a small medial elevation on its inner margin and a few minute, spine-like bristles on the first half of the inner margin.
