Leptostylus is one of the most problematic genera within Acanthocinini . Several features are extremely variable, especially the shape and width of the prosternal and mesoventral processes (Figs 2–11). Additionally, there are intermediate forms between distinctly narrow and distinctly wide processes, making it impossible to use them to attempt to divide Leptostylus . The same situation occurs with other very variable features in this genus, as for example the body shape and the length of lower eye lobes and genae. Currently, Leptostylus includes 95 species (Bezark 2024), of which we examined 46 species. Among the species examined, some of them have narrow thoracic processes, but none with them as narrow as in the new species described here (Fig. 2). Even so, we prefer not to establish a new genus based solely on the width of the thoracic processes, precisely because of the enormous variation found in the genus.</p></div>	https://treatment.plazi.org/id/03E6A70A755CFFE8FF4A3FCCE3C8FBD2	Public Domain	No known copyright restrictions apply.

Head with prominent jaws. Antennae slender, about one and three times the length of the body, first joint long, subcylindrical, second short, third barely longer than the first, fourth subequal to the third, fifth, and sixth a little shorter, the remainder not distinctly separable. There is no visible antennal vestiture. Prothorax nearly twice as broad as long, sides arcuate with no defined spine nor tubercle. Elytra long, four and a half times the prothoracic length, strongly tapering from about the middle to the apices which are moderately sharply pointed but unarmed. Legs lacking except one which probably belongs to the middle pair; this is of moderate length and stoutness, tarsal joints ill defined. Length, from front of head to tip of abdomen, 11.35 mm. Described from a single specimen. Type.—No. 2,598 M. C. Z. Florissant, Col. (No. 929 S. H. Scudder Col.). The facies of this insect are entirely that of a Leptostylus [sic, Leptostylus], with which genus it agrees in the antennal and thoracic structures. The long antennae are in accord with those of L. biustus [currently in Styloleptus Dillon, 1956] and L. terraecolor [currently in Leptostylopsis Dillon, 1956]. The coloration seems to have been a mottling, arranged in irregular transverse bands, the best marked of which are in the form of two rather broad postmedian fasciae. It will be noted that the thoracic sides, as preserved, are not symmetrical, the left one showing about the same shape as in L. biustus, while the other is simply rounded.”</p><p>Remarks. The original description and drawing (Fig. 1) do not allow considering L. scudderi as belonging to Leptostylus, Leptostylopsis, or Styloleptus . This is because currently, there are no species in these three genera with the apex of the elytra uniformly acute and divergent from apical fifth. The drawing in the original description shows a single femur on the right side and it is not clavate, while the femora are pedunculate-clavate in these genera. However, photographs of the holotype (MCZBASE 2024) show that the holotype has two femora, one on each side, and that in the left side appears to be clavate. Additionally, the original description does not inform if there are small tubercles on the elytra, which are present in the three genera mentioned by Wickham (1914). It is not possible to see if the tubercles are or are not present in the holotype. Lateral tubercles of the prothorax rounded as in L. scudderi are not rare in Acanthocinini . Therefore, we are transferring L. scudderi to incertae sedis in Acanthocinini since we have not been able to find a reliable feature that allows us to be certain about the genus of this species.</p></div>	https://treatment.plazi.org/id/03E6A70A755CFFEBFF4A39F0E702FECD	Public Domain	No known copyright restrictions apply.

Holotype male from COSTA RICA, Alajuela: Cariblanco area, 1.VI.1980, J.E. Wappes leg. (FSCA).</p><p>Etymology. The species name arcuatus (Latin, meaning “arched”) refers to the distinctive elytral markings</p><p>Remarks. Leptostylus arcuatus sp. nov. is similar to L. albicinctus Bates, 1885 but differs as follows: prothorax without dense whitish pubescence; light elytral pubescent band on posterior region of elytra forming a distinct arc; and prosternal and mesoventral distinctly narrower (Fig. 2). In L. albicinctus, the pronotum has dense whitish pubescence, light elytral pubescent band on the posterior region of elytra is transverse and usually triangularly projected forward close to suture, and the prosternal and mesoventral processes are much wider. It is somewhat similar to L. xanthopygus Bates, 1880 (see photographs on Bezark 2024 and in Santos-Silva &amp; Botero 2023), but differs by the prosternal and mesoventral processes notably narrower (much wider in L. xanthopygus). Leptostylus arcuatus differs from L. transversus (Gyllenhal, 1817) by the narrowest area of the prosternal and mesoventral processes much narrower (respectively, about half procoxal width and distinctly wider than half of mesocoxal width in L. transversus).</p></div>	https://treatment.plazi.org/id/03E6A70A755FFFEFFF4A3B78E372F915	Public Domain	No known copyright restrictions apply.

Devesa &amp; Vlasak (2023) reported the problematic definition of Pseudastylopsis in the original description and in the redescription by Linsley and Chemsak (1995). In the key to genera of Acanthocinini from North America, Linsley &amp; Chemsak (1995) separated Pseudastylopsis from Leptostylus LeConte, 1852 and Leptostylopsis Dillon, 1956, in the alternative of couplet “17:” “Prothorax with intercoxal process less than half as broad as coxal cavities,” leading to Pseudastylopsis; and “Prothorax with intercoxal process more than half as broad as coxal cavities,” leading to Leptostylus and Leptostylopsis . Nonetheless, in the same work they described P. nelsoni nelsoni from the United States of America and reported the prosternal process as “about half as broad as coxal cavity.” As the width of the prosternal process is very variable in Leptostylus and Leptostylopsis, although it is never noticeably narrow, this feature cannot be used to separate these three genera, even species from the United States of America . For example, Linsley &amp; Chemsak (1995) described the prosternal process in Leptostylopsis argentata (Jacquelin du Val) as “about as broad as coxal cavity,” exactly as in Pseudastylopsis nelsoni nelsoni . Based on the general appearance of other species currently included in Pseudastylopsis, we are provisionally describing a new species in this genus.</p></div>	https://treatment.plazi.org/id/03E6A70A755AFFEEFF4A3C1EE78DFC17	Public Domain	No known copyright restrictions apply.

Latin, “ Quissunego ” (Quis sun ego?) (Who am I?), allusive to the complicated process of including the type-species in a genus. Masculine gender.</p><p>Description. Male. Body widened, slightly flattened, less than 10 mm in the type species. Frons subsquare. Eyes moderately coarsely faceted; upper eye lobes wide, distance between them slightly larger than width of one upper lobe; lower eye lobes distinctly longer than genae; area of connection between eye lobes distinctly narrower than upper lobe.Antennae 11-segmented, distinctly longer than body; scape gradually widened from base to middle, then subparallel-sided slightly narrowed on apical fifth without apical modification, not reaching posterior margin of prothorax, with one long, erect dark seta near apex of ventral surface; pedicel cylindrical, slightly longer than wide; antennomeres III–XI filiform, without tufts of setae; III and IV similar same length, the longest, with a few short, erect, fine setae ventrally. Prothorax wider than long; anterior constriction narrow, well marked; sides slightly rounded and divergent from anterior constriction to lateral tubercles, then convergent to posterolateral angles; lateral tubercles large, as a continuation of the lateral margin, located slightly before posterior quarter. Pronotum without tubercles; sparsely, coarsely punctate on anterior 3/4, abundantly punctate on posterior quarter, punctures not following toward sides of prothorax. Prosternal process strongly narrowed centrally, then strongly widened posteriorly; narrowest area distinctly shorter than one-tenth of procoxal width. Mesoventral process narrow, gradually narrowed from base to posterior fifth, then moderately widened; narrowest area about one-eight mesocoxal width. Scutellum semicircle shaped. Elytra without tubercles and erect setae; subparallel-sided on anterior half, slightly narrowed just after humeri, then gradually convergent toward apex; apex slightly oblique and concave, with rounded outer and sutural angles; humeral angles not projected; humeral and dorsal carinae and centrobasal crest absent. Femora pedunculate-clavate; femoral clubs strongly widened; metafemora reaching apex of elytra. Tibiae cylindrical, without modifications. Metatarsomere I longer than II–III together.</p><p>Remarks. The key from Monné et al. (2020a) leads Quissunego gen. nov. to the alternative of couplet “40” with Lepturges (Lepturges) Bates, 1863 . However, the lateral tubercles of the prothorax are distinctly distant from the posterolateral angles of the prothorax, making it very artificial to consider the new species as belonging to Lepturges (Lepturges) . Furthermore, the femoral clubs are much stouter than in the species currently included in Lepturges (Lepturges) . The key from Monné et al. (2020b) leads Quissunego gen. nov. to the alternative of couplet “56,” and in it to Lophopoenopsis Melzer, 1931 . Although included in a key to genera without erect setae on elytra, we now know that the type species of Lophopoenopsis, L. singularis Melzer, 1931, has erect setae on elytra, which are absent in Quissunego . Using the key by Dillon (1956), which includes only a few American genera of Acanthocinini, Quissunego is included in the alternative of couplet “31” with Lepturges (Lepturges) . Finally, using the key to North American genera of Acanthocinini from Linsley &amp; Chemsak (1995), Quissunego is included in the alternative of couplet “10” with Sternidius LeConte, 1853, which has the mesoventral process very wide, while it is very narrow in Quissunego .</p><p>Quissunego is similar to Leiopus (Leiopus) Audinet-Serville, 1835, but differs by the upper eye lobes wide (narrow or moderately narrow in Leiopus ( Leiopus)), and the punctures on the posterior region of the pronotum do not follow toward sides of the prothorax (following toward sides of the prothorax in Leiopus (Leiopus), at least in the type species of the genus).</p><p>The key from Monné et al. (2020b) can be updated as follows, with the exclusion of Lophopoenopsis:</p><p>56(55). Distance between upper eye lobes larger than three times width of one upper lobe.... Luteolepturges Monné &amp; Monné, 2012</p><p>– Distance between upper eye lobes slightly larger than width of one upper lobe.....................

Legs. Femoral peduncles with abundant white pubescence not obscuring integument; femoral clubs with abundant light yellowish-brown pubescence not obscuring integument dorsally and on superior region of sides, and abundant white pubescence not obscuring integument on remaining surface. Protibiae with abundant whitish pubescence on basal half, more yellowish depending on light intensity and source, sparse yellowish-brown pubescence dorsally and laterally on anterior half, except both whitish and yellowish pubescence apically, and dense, bristly yellowish-brown pubescence on ventral apical half; meso- and metatibiae with sparse yellowish-brown pubescence basally, dense whitish pubescence on remaining basal half, and sparse, bristly, both yellowish-brown and brown setae on apical half of dorsal and lateral surfaces, and dense, bristly yellowish-brown pubescence on apical half of ventral surface; dorsal surface of mesotibiae with abundant, short, thick, erect dark-brown setae, setae gradually shorter toward apex. Dorsal surface of tarsomeres with abundant white pubescence not obscuring integument; metatarsomere I distinctly longer than II–III together.</p><p>Abdomen. Ventrites with abundant whitish pubescence not obscuring integument, denser apically on ventrites 1–4; apex of ventrite 5 strongly concave.</p><p>Dimensions (mm). Total length, 5.50; prothoracic length, 1.00; anterior prothoracic width, 1.25; posterior prothoracic width, 1.40; maximum prothoracic width, 1.65; humeral width, 2.15; elytral length, 4.00.</p><p>Type material. Holotype male from BOLIVIA, Santa Cruz: 4–6 km SSE Buena Vista, F &amp; F [ Flora &amp; Fauna Hotel], 1–6.IV.2003, R. Clarke leg. (MNKM).</p><p>Etymology. The species name “ similis ” (Latin, meaning “similar”) refers to the fact that this species is similar to several already described species of the genus.</p><p>Remarks. Sternacutus similis sp. nov. is similar to S. angulistigma (Bates, 1885), S. cinerascens (Bates, 1863), S. compactus Roguet, 2023, S. cribripennis (Bates, 1885), S. dimidiatus (Aurivillius, 1922), and S. griseostigma (Monné &amp; Monné, 2012) . It differs from S. angulistigma (see photographs on Bezark 2024 and drawing in the original description) by the body stouter, width about 0.4 times the total length (slender, with width almost 0.3 times the total length in S. angulistigma, the difference much more conspicuous when comparing the two species); from S. cinerascens (see photographs on Bezark 2024) especially by the upper eye lobes distinctly wider and the distance between them slightly wider than the width of one upper lobe (distinctly narrower and the distance between then larger than twice the width of one upper lobe); from S. compactus (see photographs on Bezark 2024 and original description) by the lateral tubercles of the prothorax smaller (moderately large in S. compactus), the elytral length about 1.9 times the humeral width (about 1.6 times in S. compactus), outer apex of elytra projected (not projected in S. compactus), and prosternal and mesoventral processes wider (slender in S. compactus); from S. cribripennis (see photographs on Bezark 2024 and Santos-Silva &amp; Devesa 2021) by the stouter body, width about 0.4 times the total length (slender, about 0.5 in S. cribripennis), elytra with a short and longitudinal yellowish pubescent band between base and centrobasal crest slightly contrasting with the pubescence on its sides (distinctly contrasting with the pubescence on its sides in S. cribripennis), with large dark macula on the posterior half of elytra oblique (not oblique in S. cribripennis), and by the metafemoral clubs distinctly stouter in males (slender in S. cribripennis); from S. dimidiatus (see photographs on Bezark 2024) by the stouter body (slender in S. dimidiatus, about as in S. angulistigma), distance between upper eye lobes slightly larger than the width of one upper lobe (wider than twice the width of one upper lobe in S. dimidiatus), and elytra without transverse dark macula on middle of the dorsal surface (present in S. dimidiatus); and from S. griseostigma (see photographs on Bezark 2024 and original description), by the pronotum with large subreniform dark macula on each side of middle (absent in S. griseostigma), pronotum without narrow longitudinal light pubescent band on each side of the posterior half (present in S. griseostigma), and elytra without wide and large dark zig-zag macula on posterior half (present in S. griseostigma).</p></div>	https://treatment.plazi.org/id/03E6A70A7553FFF8FF4A3997E6DAF889	Public Domain	No known copyright restrictions apply.
