Type material examined. Holotype female with 45 leg-bearing segments, body length 23 mm, from Brazil: Amazonas: Rio Tarumã Mirím, Igapó , 16 September 1976, Coll: J. Adis. ( INPA).

Supplemental morphological information. Female holotype: The following additional morphological details are provided regarding the antennae: Ventral and dorsal surface of a.a. II, V, IX and XIII with very small specialized sensilla. On the ventral side the sensilla are restricted to an internal latero-apical area, represented by two different types (a and b). Type a sensilla very thin and not split apically, type b sensilla very similar to those of the apex of a.a. XIV but thicker, with two diminutive apical branches slightly more evident than those of the latter. Specialized sensilla on dorsal side restricted to external latero-apical area and represented by three different types: a and b similar to a and b of ventral side; and type c sensilla, similar to type b; but thicker, not divided apically and darker (ocherous in color). Number and distribution of type a, b, and c sensilla as in Table 3.

Remarks. The original description by Pereira et al. (1994), only mentions two types of specialized sensilla (hereby individualized as “ type b ” and “ type c ”). The original source of this nomenclature is Pereira et al. (1995).

Distribution. Known only from the type locality.
