ANTENNAL CLUB (Fig. 5c): The nudum is 4.4 mm in length.
ANTENNOMERES (Figs. 5f, i): This species has 14 scaleless antennomeres, although the first has scales in the dorsolateral area and its proximal margin. The first of the proximal antennomeres is compressed, the second and third are isometric, and the fourth is a bit depressed. The medial and distal antennomeres are depressed, and the last distal is compressed. In the proximal segments, the l/w ratio is 1.5 in the first segment. In the second and third, l/w ratio is 1.1 and 1.0 and in the fourth is 0.9. In the median antennomeres, the l/w ratio is 0.9 and 0.8 in the fifth and sixth; from the seventh to the eleventh is 0.7 and, in the twelfth, it is 0.8. In the distal segment, the l/w ratio is 1.4. The first two antennomeres of the nudum are cylindrical. The following antennomeres are doliform but the third and fourth are more elongated. The distal segment is finger-shaped with the blunt apex.
SULCI AND PSEUDOSULCI: It exhibits 13–14 central sulci and 21–23 laterals. The trisulcate configuration is present from the third or fourth antennomere. The central sulci are present in all segments of the nudum. In the proximal, these sulci occupy 1/6 to one-fourth of the length of the antennomere that contains them; in the medial and distal ones, they occupy one-third to three-fourths. In the medial and distal segments, the central sulci occupy 1/7 to one-third of the amplitude of the antennomere. The distal margin of the antennomere truncates almost all central sulci; two rows of microtrichia m2 separate some of them from this margin. The central sulci are present from the first antennomere and in no case are they disintegrated. In all the segments, in the basal ones, the central sulci are irregular and with discontinuous edges. All sulci are elongated, and a few ends in a tip in their proximal portion. The lateral sulci appear from the third antennomere, in the two previous segments, they are absent, or in their place, there is one pseudosulcus; they are smaller than the central ones. Up to five rows of microtrichia m2 separate the lateral sulci from the distal margin of the antennomeres and are not truncated as with the central ones. They are quite irregular with very discontinuous edges. The pseudosulci (ps) are more frequent in the basal and medial segments and are absent in the first. Usually, they are small (one or three st), and large (up to eight st) are very rare and only found in the medial antennomeres. In the second and third antennomeres they are below the central sulcus; in the other segments, the pseudosulci are between the central sulcus and the lateral ones. The pseudosulci are few or absent in the fused distal antennomere.
MICROTRICHIA (Fig. 5x): They present microtrichia type m1 and m2. The l/w ratio is 1/5 to 1/ 6 in the basal antennomeres; from one-fourth to 1/ 5 in the medial and one-third to one-fourth in the distal ones.
TRICHOID SENSILLA: In this subspecies are the shortest, and their average length is 18.4 µm (15–24 µm). The st in the pseudosulci show a similar length. In the central sulcus of the last antennomere, there are trichoid and basiconic sensilla so close together that they seem to emerge from the same socket.
CHAETIC SENSILLA: They measure on average 47.7 µm (n = 4; 39–60.5 µm). They show the characteristic distribution of the subfamily. They are abundant (8 sq) at the apex of the distal fused segment.
OTHER SENSILLA (Fig. 5x): The squamiform sensilla measure on average 23.7 µm (n = 4; 22.0–33.6 µm). The coeloconic sensilla are on the sides of the antennomeres, near its proximal margin. Without considering the trichoid sensilla, the basiconic and auriculate sensilla are the most abundant (eight out of ten are basiconic or auriculate). The auriculate sensilla are also within the central sulci although in a minimal number (one or two). There is a campaniform sensillum and one styloconic sensillum with stylus, though reduced.
