Abstract
Four new species are described: Urgleptes noguerai sp. nov. (Acanthocinini), from Mexico; Styloleptus charynae sp. nov.
(Acanthocinini), from Bolivia; Nealcidion achiraense sp. nov. (Acanthocinini), from Bolivia; and Estola nearnsi sp. nov.
(Desmiphorini), from Bolivia. Notes on the differences between Pseudolepturges Gilmour, 1957 and Urgleptes Dillon,
1956 are provided. Styloleptus nigricans (Fisher, 1935) is synonymized with Leptostylus lilliputanus Thomson, 1865, and
the species is transferred to Styloleptus Dillon, 1956.
Key words: Neotropical region, South America, taxonomy
Introduction
Urgleptes Dillon, 1956 is a large genus of Acanthocinini with 97 species distributed from Canada to southern South
America, including the Caribbean Islands (Monné 2023; Tavakilian & Chevillotte 2022).
Styloleptus Dillon, 1956 is a genus of Acanthocinini and includes 20 species distributed especially in the Carib-
bean Islands, except S. biustus biustus (LeConte, 1852), known from the United States of America and some Carib-
bean Islands, and S. rhizophorae Chemsak & Feller, 1988 known only from Belize (Twin Cays Islands) (Monné
2023; Tavakilian & Chevillotte 2022).
Nealcidion Monné, 1977 is another large genus of Acanthocinini with 61 species distributed from Mexico to
southern Brazil (Monné 2023; Tavakilian & Chevillotte 2022; Bezark 2023).
Estola Fairmaire & Germain, 1859 is a large genus of Desmiphorini including 100 species known from Mexico
to southern South America, including the Caribbean Islands (Monné 2023; Tavakilian & Chevillotte 2022).
The study of specimens sent by the late James E. Wappes allowed us to recognize and describe four new species
in Urgleptes, Styloleptus, Nealcidion, and Estola. Additionally, we are synonymizing Styloleptus nigricans (Fisher,
1935) with Leptostylus lilliputanus Thomson, 1865, and transferring the species to Styloleptus Dillon, 1956. We are
also commenting on the differences between Urgleptes and Pseudolepturges Gilmour, 1957.
Material and methods
Photographs were taken at MZSP with a Canon EOS Rebel T3i DSLR camera, Canon MP-E 65 mm f/2.8 1-5X
macro lens, controlled by Zerene Stacker AutoMontage software. Measurements were taken in ‘‘mm’’ using an
ocular Hensoldt/Wetzlar—Mess 10 in the Leica MZ6 stereomicroscope, which was also used in the study of the
specimens.
Nearly all specimens used in this study were sent by the late James E. Wappes and belonged to his private col-
lection, which is now deposited at the FSCA.

RESULTS
ACANTHOCININI Blanchard, 1845
On Pseudolepturges Gilmour, 1957 and Urgleptes Dillon, 1956
Remarks. Gilmour (1957) described Pseudolepturges to include Lepturges rufulus Bates, 1885. According to him:
“Allied to the genus Lepturges Bates, but differing conspicuously by the parallel sided prothorax, in the strongly
posteriorly convex elytra and the very small eyes.” In the original description, Gilmour (1957) did not inform
whether the rows of coarse punctures on posterior region of the pronotum continues or not to the sides of the pro-
thorax. Monné & Monné (2007) reported that the row of coarse punctures on the pronotum is interrupted. However,
it is clearly not interrupted in the type species of the genus, not interrupted in P. triplarinus Nascimento & Perger,
2018 and, apparently, not interrupted in P. caesius Monné & Monné, 2007. This feature alone makes it possible to
separate Lepturges from Pseudolepturges, since in Lepturges, the row of coarse punctures does not continue toward
the sides of the prothorax. However, it does not allow separating Pseudolepturges from Urgleptes Dillon, 1956. It is
understandable that Gilmour (1957) did not make a comparison with Urgleptes because, although it was published
in 1957, the work was prepared in 1955 (or earlier), as that year appears in the publication in which Pseudolepturges
was described. The other feature pointed out by Gilmour (1957), the eye size, is very variable in Urgleptes and,
since the description of P. triplarinus, also variable in Pseudolepturges. The length of the lower eye lobes is very
variable in the species currently included in Urgleptes, and are much longer than the gena or distinctly shorter, as
for example, in U. signatus (LeConte, 1852). In the same way, the size of the upper eye lobes as well as the distance
between them are very variable in Urgleptes: from somewhat wide and about as distant from each other as the width
of one upper lobe (e.g. U. physoderus (Bates, 1885)) to slender and more distant from each other than four times the
width of one upper lobe (e.g. U. duffyi Gilmour, 1961). The prothoracic shape in Urgleptes is also very variable and
seem very similar to that in Pseudolepturges, as for example in U. multinotatus (Bates, 1881). The shape of the ely-
tra, “strongly posteriorly convex elytra,” is another variable feature in the species currently included in Urgleptes,
and may be very similar to that in Pseudolepturges, especially in P. rufulus and P. caesius (e.g. U. bruchi (Melzer,
1932)). As the antennal length may be a distinctive feature (antennae proportionally shorter in Pseudolepturges,
especially in males), we are keeping Urgleptes as different from Pseudolepturges, at least until a complete revision
of Urgleptes is done.

Dimensions (mm) (Holotype female/paratype female). Total length, 4.30/4.50; prothoracic length, 0.80/0.95;
anterior prothoracic width, 1.10/1.25; posterior prothoracic width, 1.30/1.35; maximum prothoracic width, 1.40/1.50;
humeral width, 1.95/2.10; elytral length, 3.15/3.25.
Type material. Holotype female from BOLIVIA, Santa Cruz: 4-6 km SSE Buena Vista, Flora & Fauna Hotel,
16-31.III.2003, Robin Clarke leg. (FSCA). Paratype female, same data as holotype (MZSP, formerly FSCA).
Etymology. We are pleased to name this species in honor of Charyn Micheli (Department of Entomology,
National Museum of Natural History, Smithsonian Institution, United States of America) for her contribution to the
study of Antillean Lamiinae.
Remarks. Currently, the separation between Styloleptus Dillon, 1956 (= Antilleptostylus Gilmour, 1963; =
Caribbeana Gilmour, 1963), Leptostylus LeConte, 1852, and Leptostylopsis Dillon, 1956, based on their defini-
tions and species included into them is almost impossible (Lingafelter & Micheli 2009; Micheli 2010). Based on
the chaotic concept of these three genera, the maintenance of Pygmaleptostylus Gilmour, 1963 and Styloleptoides
Chalumeau, 1983 as distinct genera becomes almost impossible. However, we are not proposing the synonymy with
one of these three genera because we have insufficient specimens of all species to allow the study of morphologi-
cal features. Notwithstanding, we are describing the new species in Styloleptus due to the presence of S. nigricans
(Fisher, 1935) in this genus (now a junior synonym of S. lilliputanus (Thomson, 1865)). Both, S. charynae sp. nov.
and S. lilliputanus share a very similar general appearance, especially the prothoracic shape, elytral pubescent pat-
tern, and presence of a slightly elevated centrobasal crest with tuft of setae on its top.
Styloleptus charynae sp. nov. differs from S. lilliputanus (Figs 14–16) by rounded area of the sides of the
prothorax less projected (very projected in S. lilliputanus), posterior half of the elytra with wide and oblique dark
brownish orange band on posterior half (absent in S. lilliputanus), and pubescence on this band contrasting in color
with that on apex (pubescence on the elytral apex not contrasting with that on remaining posterior half in S. lillipu-
tanus).

Remarks. Based on the short original description of Leptostylus lilliputanus Thomson, 1865 (Fig. 14), but especial-
ly on the photograph of the holotype, it is not possible to find a reliable difference with Leptostylus nigricans Fisher,
1935 (Fig. 15) (= Leptostylus puertoricensis Fisher, 1935 (Fig. 16)). Even the dimensions are very similar: 4 mm
in L. nigricans and L. puertoricensis; 3 mm in L. lilliputanus. We are following Micheli (2010) who transferred L.
nigricans to Styloleptus, and transferring L. lilliputanus to this genus. Leptostylus lilliputanus was described as from
“Columbia,” while L. nigricans and L. puertoricensis were described from Puerto Rico. However, we do not know
if the type locality of L. lilliputanus is correct. Furthermore, as L. lilliputanus was described in 1865, the holotype
was collected at the latest in 1865. Furthermore, what is now known as Colombia did not cover the same territory in
the 19th century. Depending on the year, it could include Venezuela, Ecuador, and Panama.

Nealcidion achiraense sp. nov. is somewhat similar to N. brachiale (Bates, 1872) (Fig. 26) and N. emeritum (Erich-
son, 1847) (Fig. 27), but differs by the scape not sinuous on inner surface (sinuous in N. brachiale and N. emeritum),
centrobasal crest of the elytra longer and tuberculate about middle and apex (shorter and not tuberculate dorsally in
N. brachiale and N. emeritum), and elytra with moderately wide and oblique whitish pubescent band, inclined back-
ward from humeral carina to suture (with very wide whitish pubescent band, inclined forward from sides to suture
in N. brachiale; short irregular, inclined forward, sometimes as in N. kayi, in N. emeritum).

Etymology. We are happy to name this species in honor of Eugenio H. Nearns (National Museum of Natural
History, Smithsonian Institution, United States of America) for his friendship and for his great contribution to the
knowledge of the Onciderini (Coleoptera, Cerambycidae, Lamiinae).
Remarks. Estola nearnsi sp. nov. is similar to E. annulipes Breuning, 1940 (see photographs on Bezark 2023
and Galileo & Martins 2006), but differs by the lower eye lobes distinctly longer than genae (according to Breuning
(1974), lower eye lobes half as long as genae in E. annulipes), frons distinctly wider than long (according to Breun-
ing (1974), frons as wide as long), and pronotum without oblique yellowish band basally (present in E. annulipes).
The new species differs from E. fuscomarmorata Breuning, 1940 (see photographs on Bezark 2023 and Lingafelter
et al. 2023) by the body stouter (slender in E. fuscomarmorata), antennomeres III and VI bicolorous (entirely dark
in E. fuscomarmorata), and elytral pubescence not forming oblique band on anterior third (forming in E. fusco-
marmorata). Estola nearnsi sp. nov. can be separated from E. nigrosignata Breuning, 1940 (see photographs on
Bezark 2023) and E. obscura (Fabricius, 1793), by the elytra without grayish-white or whitish pubescent maculae
interspersed (grayish-white or whitish pubescence present on the elytra of E. nigrosignata and E. obscura); from
E. compacta Breuning, 1940 (see photographs on Bezark 2023), by the elytra without wide dark pubescent area
on anterior half (present in E. compacta); from E. hispida Lameere, 1893 (see photograph on Bezark 2023), by the
body stouter (slender in E. hispida), and elytral punctures not distinctly contrasting with the pubescence (distinctly
contrasting in E. hispida); and from E. timbauba Martins & Galileo, 2006 (see photographs on Bezark 2023 and
original description), by the pronotal and elytral pubescence distinctly denser (sparser in E. timbauba, especially on
the pronotum).
