Head, anterior lobe of pronotum, and scutellum shining reddish brown; apex of tylus, posterior lobe of pronotum, clavi and coria shining chestnut orange; head basally with two iridescent spots, one on either side of midline, each spot consisting of a series of parallel ridges; antennal segment I pale reddish brown, II-IV chestnut orange; humeri yellow; anterolateral borders of pronotum shining reddish brown; hemelytral membranes hyaline ambarine to dark yellow. Ventral coloration. Head, thorax and abdominal sterna shining reddish brown; rostral segments I-IV yellow (apex of IV brown); coxae and trochanters shining chestnut; femora shining chestnut with apices pale; tibiae and tarsi yellow; ostiolar peritremes dark orange; evaporative areas dark brown. Structure. Body length shorter than 3.9 mm, width greatest beyond middle. Head. Impunctate; vertex convex; ocelli absent; ventrally with short, shallow longitudinal sulcus; rostrum reaching posterior border of metasternum; rostral segment I extending just beyond level of middle of eye. Thorax. Pronotum glabrous, bilobed, transverse impression shallowly incised; posterior pronotal lobe with scattered shallow punctures. Hemelytra. Macropterous; clavi and coria glabrous; hemelytral membranes reaching apex of last abdominal segment. Abdomen. Sterna sparsely clothed with fine longer hairs.
Male. Not examined.
Measurements. Female. Body length 4.00; head length 0.67; head width across eyes 0.72; interocular distance 0.45; preocular length 0.46; length antennal segments: I 0.51, II 0.67, III 0.51, IV 0.55; pronotum: total length 0.75; maximum width across humeral angles 1.20; scutellum: length 0.70; width 0.72.
General distribution*. Only known from Argentina and Brazil. ARGENTINA: CHACO (P. N. Chaco); CORDOBA (Los Cocos); MISIONES (Parque Nacional Iguazu); SALTA (Departamento General San Martin, Abra Grande, Oran). BRAZIL (Minas Geraes, Piracicaba, Espiritu Santo, Bahia). (Brailovsky 1981; O’Donnell 1986, Dellapé, et al. 2015).
* The following records given by O’Donnell (1986) are erroneous and belong to another species: BAR- BADOS (Parish St. Michael). TRINIDAD (St. Augustine). VENEZUELA (Sucre, Maracay, Portuguesa, Aragua, Yaracuy).
Material examined. New records: ARGENTINA: 3 females, Tucuman, Buruyacu-Chilcas, 10.xi.1979, col. Golbach (UNAM); 1 female, Entre Rios, xii.1976, col. D. Carpintero (UNAM).
Discussion. Bubaces enatus, belongs to “ uhleri ” group. It is similar to B. uhleri in having the pronotum, clavi and coria glabrous,the body length shorter than 4.30 mm., rostral segment I is short, reaching only the middle third of the eye, ocelli are absent, and the rostrum reaches the posterior border of the metasternum.
In B. uhleri, known from the West Indies, each corium has a circular pale yellowish-orange subapical spot and the femora are tuberculate (Fig. 6). In B. enatus, recorded from Argentina and Brazil, each corium lacks a circular yellow subapical spot, and the femora lack tubercles (Fig. 3).
