The species is named in honor of our colleague Jean-Louis Giuglaris, of Matoury, French Guiana, in recognition of his ongoing efforts in collecting and rearing cerambycids and making them available for study.	en	Santos-Silva, Antonio, Bezark, Larry G., Tavakilian, Gérard L., Audureau, Alain (2025): Cerambycidae (Coleoptera) biodiversity in French Guiana: description of a new genus and four new species in Acanthocinini (Lamiinae).

03E77501FFF6FFAFFF2B7BA3C503FF5F.taxon	discussion	Remarks. Baryssinus is a problematic genus that includes species with (e. g. B. marisaea Martins & Monné, 1974) and without (e. g. the type species, B. penicillatus Bates, 1864) erect setae on the elytra. Females of Baryssinus have the ovipositor long and distinctly surpassing the elytral apex. Therefore, we chose to describe the new species in Baryssinus until it is possible to make a complete revision of the genus. Baryssinus giuglarisi sp. nov. is similar to B. albifrons Monné & Martins, 1976 (see photographs on Bezark (2025) and in Monné et al. (2020 a )) and B. bilineatus Bates, 1864 (see photographs on Bezark (2025) and in Monné (1990 )), but differs as follows: pronotum without longitudinal dark band on each side of middle; elytra without oblique dark pubescent band from apex of centrobasal crest to near suture; elytra without longitudinal dark pubescent band dorsally after middle; elytra with longitudinal white pubescent bands dorsally; elytra without dense white pubescent macula apically; and apex of abdomen distinctly surpassing elytral apex in females. In B. albifrons and B. bilineatus, the pronotum has a longitudinal dark band on each side of the middle, elytra with oblique dark pubescent band from apex of centrobasal crest to near suture and dark longitudinal pubescent band dorsally after middle (sometimes, absent in B. bilineatus), elytra without longitudinal white pubescent bands dorsally and with dense white pubescent macula apically, and apex of the abdomen slightly surpassing the elytral apex in females.	en	Santos-Silva, Antonio, Bezark, Larry G., Tavakilian, Gérard L., Audureau, Alain (2025): Cerambycidae (Coleoptera) biodiversity in French Guiana: description of a new genus and four new species in Acanthocinini (Lamiinae).

03E77501FFF2FFA2FF2B799EC280FA43.taxon	etymology	Etymology.

03E77501FFF2FFA2FF2B799EC280FA43.taxon	discussion	Remarks. According to Gilmour (1960) Nyssodrysternum has “ a distinct, narrow apical cicatrix. ” However, currently, Nyssodrysternum includes species with (e. g. N. fasciatum Gilmour, 1960), sometimes very narrow, almost absent (e. g. N. serpentinum (Erichson, 1847 )), or without (e. g. N. amparense (Melzer, 1934 )) an apical cicatrix on the scape. This suggests that it includes species belonging to at least two genera, or that the feature is extremely variable in the genus. Nyssodrysternum angulatum sp. nov. is similar to N. freyorum (Gilmour, 1963) (see photograph on Bezark (2025) and in Gilmour (1963 a )) but differs as follows: light elytral pubescence on basal half forming a subrectangular macula with its inner apex projected backward; and elytra with M-shaped dark macula dorsally on posterior third. In N. freyorum, the light elytral pubescence on the basal half does not form a subrectangular macula and posterior third of elytra without M-shaped dark macula dorsally.	en	Santos-Silva, Antonio, Bezark, Larry G., Tavakilian, Gérard L., Audureau, Alain (2025): Cerambycidae (Coleoptera) biodiversity in French Guiana: description of a new genus and four new species in Acanthocinini (Lamiinae).

03E77501FFFFFFA3FF2B7E3AC363FC6F.taxon	discussion	Remarks. According to Dillon (1956), the prosternal process in Styloleptus is “ one-fourth to one-third as broad as a prosternal cavity. ” In the original description of the genus, Dillon (1956) included the type species, Styloleptus biustus (LeConte, 1852), and Styloleptus minuens (Hamilton, 1896) (currently, = S. scurra (Chevrolat, 1862 )). However, the narrowest area of the prosternal process in S. scurra is distinctly wider than one-third of the width of a procoxal cavity (see photograph in Devesa et al. 2019). Gilmour (1963 a) included in Styloleptus: S. caymanensis (Fisher, 1948); S. lewisi (Fisher, 1948); S. parvulus (Gahan, 1895); S. thompsoni (Fisher, 1948); S. atrovittatus (Fisher, 1925); S. dozieri (Fisher, 1932); S. infuscatus (Fisher, 1932); S. laticollis (Fisher, 1925); S. maraicola (Fisher, 1942); S. pilosellus (Fisher, 1942); S. cubanus (Fisher, 1926) (described as L. biustus var. cubanus); S. scurra (Chevrolat, 1862); S. variabilis (Fisher, 1925); S. puertoricensis (Fisher, 1935); S. darlingtoni (Fisher, 1942); S. vanduzeei (Fisher, 1935); and S. planicollis (Fisher, 1935). Additionally, Gilmour (1963 a) described S. nigrofasciatus and S. divisus, and described Antilleptostylus for A. nigricans (Fisher, 1935). Gilmour (1963 b) described Caribbeana for C. hebes Gilmour, 1963. Many species included by Gilmour (1963 a) are currently junior synonyms of other species of Styloleptus. Ivie (1985) synonymized Caribbeana with Styloleptus, and Micheli (2010) synonymized Antilleptostylus with Styloleptus. We agree with Micheli (2010), who reported that the width of the prosternal process cannot be used to define Styloleptus. In fact, it is distinctly wider than half the width of the procoxal cavity, at least in some species. Still, according to Dillon (1956): “ Elytra densely punctate but punctures largely concealed by vestiture, with several prominent costae and usually with a number of fine elevated points or fine tubercles; basal gibbosity nearly wanting; apices obliquely truncate at suture. ” However, the pubescence does not obscure the punctures in some species, at least on considerable areas of the elytra (e. g. S. posticalis (Gahan, 1895) and S. scurra); the elytral costae [carinae] are absent or nearly so in some species (e. g. S. lilliputanus (Thomson, 1865) and S. inermis (Fabricius, 1801 )), and may or may not be distinct in the same species, as reported by Micheli (2010); and the small elytral tubercles (not the centrobasal crest) may be absent or nearly so (e. g. S. darlingtoni (Fisher, 1942 )) — reported in the original description as “ usually ” present. Dillon (1956) and Linsley & Chemsak (1995) described the sides of the prothorax respectively: “ lateral tubercles broad, unarmed, imperceptibly [sic] merging with side margins anteriorly, strongly angularly rounded to the constricted base; ” “ sides with obtuse tumid tubercles just before basal impression. ” Nonetheless, the posterior region of the lateral tubercles of the prothorax is distinctly angled in some species (e. g. S. atrovittatus and S. infuscatus), or even somewhat sinuous with a short, pointed apex (e. g. S. cubanus). Therefore, as in several genera of Acanthocinini, the current definitions are very fragile, and a comprehensive revision is needed to try to provide a reliable definition for Styloleptus. The new species described herein is tentatively included in Styloleptus due to its general similarity to other species currently included in it.	en	Santos-Silva, Antonio, Bezark, Larry G., Tavakilian, Gérard L., Audureau, Alain (2025): Cerambycidae (Coleoptera) biodiversity in French Guiana: description of a new genus and four new species in Acanthocinini (Lamiinae).

03E77501FFFBFFA4FF2B7ECAC5E1F9EA.taxon	discussion	Remarks. The keys from Monné et al. (2020 b, 2020 c) lead the new genus to Hamatastus Gilmour, 1957. However, Sternacutoides gen. nov. differs from Hamatastus as follows: lateral tubercles of prothorax located near posterolateral angles; and elytra somewhat cuneiform. In Hamatastus, the lateral tubercles of prothorax are located on beginning of the posterior third or closer to middle, and the elytra are parallel-sided or almost so from base to about posterior quarter or fifth. The new genus also shares the centrobasal crest projected backward with Pucallpa Lane, 1959, but differs by the prothorax with small and acute lateral tubercles (absent in Pucallpa), and elytra without small tubercles (present in Pucallpa). Anisolophia Melzer, 1935 is another genus with the centrobasal crest of elytra projected backward, but differs from Sternacutoides by the lateral tubercles of the prothorax larger and located on middle (smaller and located near apex in Sternacutoides), pronotum tuberculate (not tuberculate in Sternacutoides), and lower eye lobes about as long as genae (distinctly longer in Sternacutoides). The key from Monné et al. (2020 c) can be updated as follows: 18 (17). Sides of prothorax with distinct tubercle, acute at apex ....................................................... 18 ’ - Sides of prothorax without tubercle or, at most, with rounded protuberance ....................................... 19 18 ’ (18). Lateral tubercles of the prothorax distant from the posterolateral angles; elytra not distinct narrowed only from apical quarter ........................................................................
