Abstract. A new species of Polytes Stål, P. debra Eger (Heteroptera: Scutelleridae: Pachycorinae) is described based 
on a single female collected in Peru. The new species is described and fi gured and compared to P. ruth (Breddin), 
its most similar congener. A revised key to species of Polytes is provided.
Key Words. Polytes, New World.
Introduction
 The genus Polytes Stål was revised by Eger (1990) and included 18 species. An additional species, 
that was described in Pachycoris Burmeister was subsequently added to the genus (Eger 1994). During 
a collecting trip to Peru in 2012, I collected a single female of an undescribed species that is described 
herein.
Materials and Methods
 Terminology for external female genitalia follows McDonald (1966). Photos were taken and edited 
using Auto-Montage™ software (Syncroscopy, Cambridge, UK). All measurements are given in mm. 
Polytes debra Eger, new species
Description. Dorsum (Fig. 1) densely, fi nely punctate, punctures provided with short curved setae. 
Dorsal coloration black with following orange markings: pair of large macules on pronotum, each con-
tiguous with posterior pronotal margin and occupying a large part of each side of pronotum; cicatrices 
mesially and thin longitudinal line between cicatrices; large transverse macule stretching across scu-
tellum beginning at about 1.0 mm posteriad of basal margin and extending nearly half-way to apex of 
scutellum; and claval vein on hemelytra. Anterolateral pronotal margins, lateral margin of hemelytra 
basally, lateral margin of connexiva and extreme apex of scutellum bordered with thin pale line; apex 
of tylus pale. Venter black (Fig. 2) with the following pale markings: fi ne line along lateral margins of 
pronotum, hemelytra basally, and abdomen; fi ne line on posterior margin of seventh sternite mesially, 
this not as wide as tibial diameter; base of head, and parts of fi rst two rostral segments, and anterior 
margin of prosternum. Ventral punctation moderately dense laterally, sparse mesially, most provided 
with fi ne curved setae. Length of body 10.5, width at widest point 7.2.
 Head broadly rounded apically (Fig. 3), relatively short, width at 1/4 of distance from apex to base 
equal to about 3/4 of head length; lateral margin before eyes sharply angled; length 2.1, width 3.05, 
interocular distance 1.95, interocellar distance 1.0. Length of antennal segments 1–5: 0.7; 0.6; 0.7; 1.3; 
1.6. Rostrum reaching posterior margin of metasternum, length of segments 1–4: 1.1; 1.6; 0.65; 1.0.
 Pronotum rather evenly convex, slightly impressed submarginally along anterolateral margins; an-
terolateral margins convex, carinate, posterolateral margins sinuate, posterior margin concave. Length 
of pronotum at meson 3.25, width across humeri 6.65. Scutellum strongly convex, 7.1 long, maximum 
width 7.1. Legs black, coxae and trochanters somewhat lighter colored and with some pale markings.

 Abdominal venter uniformly black except for pale markings mentioned previously. Mid-ventral 
length of segments 3–7: 0.6; 0.6; 0.45; 0.5; 1.9.
 Female genital plates (Fig. 4). First gonocoxae elongate, relatively thin, moderately punctate and 
wrinkled, provided with few long setae; posterior margins broadly concave laterally, narrowly convex 
mesially; mesial margins contiguous, distinctly but narrowly elevated. Exposed portion of second 
gonocoxae small, pale. Ninth paratergites elongate; mesial margins rounded, narrowly overlapping; 
sparsely punctured, provided with sparse long setae mesially; anterior margins laterally and posterior 
margins mesially pale-bordered. Eighth paratergites narrow, sparsely punctured; posterior margins 
pale, provided with row of long setae.
Type Material. HOLOTYPE: female, labeled: a) PERU: San Martín Dept., Mirador Alto Mayo, Km 
374 on 5N, 18-X-2012, 1960 m., J. E. Eger. b) S 05º40’07.9”, W 077º45’22.0”. Deposited in the Florida 
State Collection of Arthropods, Gainesville, FL. There are no paratypes.
Comments. Polytes debra is similar to P. ruth (Breddin) in overall size, the shape of the head, and 
the presence of a thin pale line on the posterior margin of the last sternite. The dorsal coloration is 
quite different, though. The latter species is known only from males which are relatively consistent in 
coloration (Fig. 5). Polytes debra is similar in color except that the pronotal macules are not invaded by 
a lanceolate marking, and the scutellar macule does not cover most of the scutellum, and is not inter-
rupted mesially by black. In addition, the dorsal surface of P. ruth tends to be relatively glabrous and 
mostly lacks setae in punctation, whereas the dorsal surface of P. debra is matte and most punctures 
are provided with setae (this difference may be an artifact of specimen age); the area around the cica-
trices in P. ruth tends to be more strongly impressed than in P. debra; the lateral margin of the head 
anterad of the eyes is sharply angled in P. debra, smoothly rounded in P. ruth (Fig. 6). It is conceivable 
that P. debra is a female of P. ruth, but the fact that the coloration of P. ruth was relatively consistent 
and species of Polytes for which both sexes are known do not display sexual dimorphism in coloration 
leads me to believe that this is a distinct species.
 Within the fenestra species group, P. debra can be recognized by the head broadly rounded ante-
riorly, the lack of a bilobed pale macule mesially on the posterior margin of the seventh sternite, and 
the distinctive color pattern. The type of P. debra was swept by me along a roadside and immediately 
recognized as distinctive. I returned to this area and swept and beat intensively, but was not able to 
fi nd additional specimens.
Etymology. This species is dedicated to my wife, Debra Eger, for many years of love, support and 
encouragement.

Deposited in the Florida State Collection of Arthropods, Gainesville, FL. There are no paratypes.Comments. Polytes debra is similar to P. ruth (Breddin) in overall size, the shape of the head, and the presence of a thin pale line on the posterior margin of the last sternite. The dorsal coloration is quite different, though. The latter species is known only from males which are relatively consistent in coloration (Fig. 5). Polytes debra is similar in color except that the pronotal macules are not invaded by a lanceolate marking, and the scutellar macule does not cover most of the scutellum, and is not inter-rupted mesially by black. In addition, the dorsal surface of P. ruth tends to be relatively glabrous and mostly lacks setae in punctation, whereas the dorsal surface of P. debra is matte and most punctures are provided with setae (this difference may be an artifact of specimen age); the area around the cica-trices in P. ruth tends to be more strongly impressed than in P. debra; the lateral margin of the head anterad of the eyes is sharply angled in P. debra, smoothly rounded in P. ruth (Fig. 6). It is conceivable that P. debra is a female of P. ruth, but the fact that the coloration of P. ruth was relatively consistent and species of Polytes for which both sexes are known do not display sexual dimorphism in coloration leads me to believe that this is a distinct species. Within the fenestra species group, P. debra can be recognized by the head broadly rounded ante-riorly, the lack of a bilobed pale macule mesially on the posterior margin of the seventh sternite, and the distinctive color pattern. The type of P. debra was swept by me along a roadside and immediately recognized as distinctive. I returned to this area and swept and beat intensively, but was not able to fi nd additional specimens.Etymology.
