ANTENNAL CLUB (Fig. 10a, b). The scaleless club is 540 µm in length in the male and 580 µm in the female.
ANTENNOMERE (Fig. 10 a–d). There are four scaleless antennomeres, and the distal two are fused. In the male, the dorsal and ventral surfaces of the distal antennomere have a suture; in the female, there is an interrupted division in the basal antennomere. The flagellomere immediately preceding the scaleless antennomere shows a small uncovered area that is slightly larger in the female than in the male. The antennomeres are not as depressed as congeners, and the maximum ratio (l:w) is 1:3. The scaled area of the dorsal surface extends two antennomeres beyond that of the ventral surface.
SULCI AND PSEUDOSULCI (Fig. 10e, f). The male has 4 central and 8–9 lateral sulci and the female 4 central and 9 lateral; the trisulcate configuration is present from the basal antennomere. The sulci are very irregular and disaggregated; some are slender at their proximal end. The central sulci usually do not occupy the entire length of the antennomere but reach nearly to the distal edge, except in the basal antennomere. The lateral sulci extend toward the dorsal surface from the second antennomere; in the distal antennomere they are not visible on the ventral surface. There are some pseudosulci, especially in the male.
MICROTRICHIA (Fig. 10g, h). In this species we observed m1, m2, and m4. The st:m1 ratio is 1:2.
TRICHOID SENSILLA (Fig. 10g). Theses sensilla average ca. 14 µm in length. In the central sulci, their number ranges from 17 to 67, for a total of 195 in the female and 257 in the male.
CHAETIC SENSILLA. The chaetic sensilla average ca. 21.2 µm in lnegth. There are six or seven on the ventral surface and additional six on the dorsal surface, for a total of up to 12 per antennomere. On the dorsal surface they are located near the lateral sulci and toward the upper margin of the antennomere.
BASICONIC SENSILLA. Basiconic sensilla are scarce and located on the ventral and dorsal surface.
AURICULATE SENSILLA (Fig. 10h). These sensilla are frequent on the ventral surface and on the dorsal surface, where they are located near the lateral sulci.
COELOCONIC SENSILLA (Fig. 10i, j). In most cases, sc1 are found on the dorsal surface and are also abundant in the ventral lateral area of the distal antennomere; they usually occur in pairs.
OTHER SENSILLA (Fig. 10k, l). The campaniform sensilla are found only in the basal antennomere without scales, and on the dorsal surface. The styloconic sensilla without stylus are present at the apex of the last antennomere.
