03ED8784FFA8DA61FCC6CDA14173D17E.taxon	discussion	Remarks. – Comparing the paratypes, we can see that the shape of the prothorax varies from trapezoidal to almost rectangular. This variation does not allow the new species to be considered equal to any of the other known species. Examination of several specimens and the recent descriptions of new species showed that the species of Xixuthrus present a high rate of endemism by island or even by biotope (low or high altitude). All specimens previously identified as Xixuthrus helleri are now considered three different species. Length. – 56.4 – 69.6 mm (from apex of mandibles to elytral apex).	en	Delahaye, Norbert, Marazzi, Giuseppe, Marazzi, Valentino, Missori, Paolo (2024): Synonymy and description of a new species in Xixuthrus Thomson, 1864 from Indonesia (Coleoptera, Cerambycidae, Prioninae, Macrotomini, Xixuthrina).

03ED8784FFAADA6FFF4FCF69465DD1A3.taxon	description	“ 1. Daemonarthra Helleri nova species. Une seule femelle, de la Nouvelle-Guinée anglaise (contrée de l'Astrolabe), communiquée par M. le Dr Heller, directeur du Musée de Dresde. La longueur est de 53 millimètres, la teinte d'un brun marron foncé; l’Insecte est recouvert d'une pubescence d'un jaune doré, mais la suture et quatre bandes longitudinales accompagnant les côtes élytrales sont dénudées. Les mandibules sont un peu plus convexes que chez Xixuthrus, et elles manquent de dent externe vers l'extrémité. Les antennes atteignent le milieu des élytres; le 1 er article, qui dépasse considérablement le niveau du lobe postérieur de l'oeil, est très déprimé, tranchant au bord interne qui est très peu denticulé; sa ponctuation est grosse et confluente; il est égal aux 3 e et 4 e réunis; le 3 e est un peu plus long que le 5 e et surtout que le 4 e, la différence entre le 4 e et le 5 e étant plus prononcée que chez Xixuthrus microcerus; l'angle interne de tous les articles est avancé, mais non épineux; le système porifère est très développé: il couvre déjà tout le côté interne du 4 e article, presque tout le 8 e et entièrement les trois derniers. La tête est rugueuse, granuleuse en arrière et derrière les yeux. Les côtés du prothorax sont épineux, el ils convergent peu en avant; les angles antérieurs sont développés en un lobe formant une courte oreillette. Le pronotum, couvert çà et là de granulations, est très inégal: il offre deux dépressions postérieures très marquées et des crêtes lisses et dénudées disposées absolument comme chez Xixuthrus heros. L'écusson offre une fine ponctuation réticulée. Les élytres sont épineuses à l'angle sutural, et elles présentent de gros points superficiels accompagnant les côtes: celles-ci sont peu saillantes, sans anastomoses, la 3 e étant plus près de la plus externe que de la 2 e. Le prosternum est légèrement rugueux sur la saillie qui est peu rétrécie au milieu; tout le métasternum el l'abdomen offrent une très fine ponctuation serrée. Les pattes ont tous les fémurs épineux en dessus et en dessous, et tous les tibias très épineux dans tous les sens. ” Length. – 49 - 91 mm (specimens from GVMPC)	en	Delahaye, Norbert, Marazzi, Giuseppe, Marazzi, Valentino, Missori, Paolo (2024): Synonymy and description of a new species in Xixuthrus Thomson, 1864 from Indonesia (Coleoptera, Cerambycidae, Prioninae, Macrotomini, Xixuthrina).

Teguments blackish, palps reddish, antennae from apex of 3 rd antennomere onwards dark reddish brown, becoming paler towards apex; dorsal parts extensively covered with short, more or less dense golden pubescence, here and there lacking or reduced to scattered hairs only visible at certain angles, possibly because worn-out. Body stocky, rather broad and flattened. Head massive, a little less than 2 / 3 pronotum wide (ratio = 0.67), with deep medial longitudinal groove, covered with more or less sparse pubescence, distinctly denser on epistome; eyes fairly large, in dorsal view distance between them about 3 / 4 eye width; mandibles fairly elongate, about 2 / 3 as long as antennal scape, with outer edge almost evenly rounded from base to apex, with external preapical tooth hardly visible, with double punctuation consisting of coarse punctures separated by partly narrow and wrinkled, partly wide and finely punctate intervals, covered with sparse pubescence, except for apex and along inner edge. Antennae rather short, reaching backwards about mid-length of elytra, scape elongate (ratio scape length / head width = 0.65), very weakly arcuate, surface microreticulate and dull with coarse punctation made of deep, elongate punctures; 3 rd antennomere short, hardly longer than one 14 15 16 half scape; following articles shorter and of equal length until 6 °, then becoming progressively longer until 10 °, 11 ° distinctly longer (XI / X length ratio = 1.28), only slightly arcuate. Pronotum subtrapezoidal, with sides slightly divergent rearwards, transverse (length / width ratio = 0.56), with distinct medial impression, covered with pubescence, dense and continuous along lateral edges, scattered or lacking on extensive areas in central position, therefore conspicuously blotchy in appearance; surface, only visible in areas lacking pubescence, with uneven, double reticulate punctuation; medial impression laterally edged with a pair of elongate, irregular bumps, about one half as long as the pronotum, anteriorly finely, densely and evenly punctate, posteriorly microreticulate, fairly shiny with scattered, large punctures; external to those two farther, much smaller bumps, from where two oblique crests reach the posterior angles; anterior angles hardly projecting forwards, their front side with a pair of very weak undulations; behind those pronotum sides with some uneven, blunt-tipped teeth, rearwards increasingly obtuse; posterior angles elongated into short, slender tooth; posterior edge internal to angles oblique and subrectilinear about as far as articulation with mesothorax, there with an obvious obtuse tubercle, in the middle distinctly convex and projecting rearwards. Scutellum pubescent, posteriorly rounded. Elytra with broad, flat, glabrous costae, with reticulate, fairly shiny surface, covered with dense, uneven punctuation, double in basal portion, increasingly scattered rearwards; such costae delimit five conspicuous, pubescent stripes, about as wide as twice to three times the adjacent costae; apex broadly rounded and armed with a robust sutural tooth. Legs fairly developed, fore femora a little sho 1 ter than mid ones (fore femur length / pronotum width ratio = 0.76), tegument weakly microreticulate and fairly shiny, with rows of short, slender, irregularly spaced spines along inner femoral and tibial edges; fore femora with coarse punctures, close and with strongly raised intervals towards femoral apex; mid and hind ones with much smaller and more scattered punctures, with flat intervals; all tibiae coarsely and closely punctate, fore ones close to apex obviously expanded and distinctly bent outwards. Fore tarsi short, about 9 / 10 head width, poorly expanded; 1 st tarsomere, as seen in dorsal view, not longer than 2 nd; last tarsomere a little longer than the first three together (ratio = 1: 10). ” Length. – 56 - 61 mm.	en	Delahaye, Norbert, Marazzi, Giuseppe, Marazzi, Valentino, Missori, Paolo (2024): Synonymy and description of a new species in Xixuthrus Thomson, 1864 from Indonesia (Coleoptera, Cerambycidae, Prioninae, Macrotomini, Xixuthrina).
