No full textLamellipalpus flavomarginatus sp. nov. (Fig. 11) Type locality: India, Assam, Lushai Hills (today in Mizoram). Description. 3. Habitus: Oblong, testaceous with the elytra brown except for suture and the side which are narrowly yellow testaceous along the whole length. Underside completely testaceous. Head: Transverse, testaceous yellow; distance from eye to pronotum equal to 1.8 times diameter of eye. Interocular space very large, 3 times as large as eye diameter. Anterior margin of frons concave, straight on middle. Head slightly depressed on antero-median part. Surface shining, covered with fine punctures and very fine and long yellow setae. Mandibles long, evenly curved. Last segment of maxillary and labial palpi broad, 3.3 times as long as broad, flattened and strongly elongate, about 1 / 3 longer than mandibles, with fine pubescence; setae dense, fine and testaceous. Antennae short, flattened, 1 st and 3 rd joints elongate, 2 nd joint very small, 4 th– 11 th joints subequal and about 1.4 times as long as broad at the broadest point. Pronotum: Testaceous yellow, transverse, depressed posteriorly before angles. Sides rounded and convex. Posterior angles protruding and slightly obliquely carinate. Entire surface shining with small punctures, each with a long and very fine yellow seta. Scutellum broad, triangular and testaceous. Elytra: Brown, narrowly testaceous yellow along suture and outer margin, both of these along their whole length. Sides slightly dilated, broadest behind middle, with 3 distinct costae and coarsely punctured. Punctures strongly impressed, very large and much closer together than their own diameter, all individually visible. Pubescence dense; setae short, very fine and brown. Elytral margin distinctly bordered. Underside: Completely testaceous, finely and densely pubescent. Aedeagus: Small, lateral lobes thin and narrow, rounded posteriorly, ending in a sharp point dorsally. Median lobe with a sharp ridge dorsally. Female: Unknown. Measurements: TL: 7.6 mm; TL-H: 7.1 mm; HL: 1.2 mm; HW: 2.2 mm; LP: 2.2 Type material: Holotype 3 (NHMB): “Assam, Sairang, Lushai Hills / 29.9. 1960, 200/ 500 ’, F. Schmid” “ Lamellipalpus nigripennis Pascoe, det. W. Wittmer” [white Wittmer-handwritten label]. “ Holotype Lamellipalpus flavomarginatus sp.n. Brancucci & Geiser 08” [red printed label]. Etymology: This species is characterized by brown elytra with a testaceous sutural and marginal seam. Affinities: This species is very easy to determine because of the peculiar colour, the flattened antennae, and the very slightly depressed head. Distribution: NE India (Mizoram).Published as part of Brancucci, Michel & Geiser, Michael, 2009, A revision of the genus Lamellipalpus Maulik, 1921 (Coleoptera, Lampyridae), pp. 1-20 in Zootaxa 2080 on pages 12-14, DOI: 10.5281/zenodo.18733

The single known male specimen of D. viridimontanum sp. nov. was fixed with an everted internal sac, which exacerbates the morphological comparison with other species. Etymology The specific epithet viridimontanum refers to the type locality of the species, Monte Verde (Minas Gerais state, Brazil), which translates to ‘green hill’ from Portuguese. Type material Holotype BRAZIL • ♂; Minas Gerais, Monte Verde; 22 Feb. 1960; J. Halik leg.; MZSP 46483 (Fig 4A). Paratype BRAZIL • 1 ♀; same collection data as for holotype; 2 Feb. 1970; MZSP 46484.

Pronotum (Fig. 7J) wide, about 1.4 times as wide as long; anterior margin and anterior angles arched; lateral margins slightly sinuate, with shallow notch at posterior third; anterior, posterior and lateral margins not elevated; integument smooth, densely covered with very fine yellow setae. Elytra very long, each elytron 5.7 times as long as wide, almost parallel; integument coriaceous, densely covered with short and fine decumbent setae, and much longer thick erect setae. Legs slender, densely pubescent, covered with long and thick setae; tarsi flattened dorsoventrally, fourth tarsomere with a transversal slit at base; anterior prothoracic tarsal claws (Fig. 9J) broadly lobed basally, lobe with very broad rounded margin; posterior claws on meso- and metathoracic tarsal claws apparently split at apex, with fine protruding tooth slightly shorter than claws. Abdomen weakly sclerotised, coriaceous, densely covered with long setae; ventrite VI notched at posterior margin; ventrite VII (Fig. 10J) with triangular lobes, inner margins nearly parallel, outer margins convergent posteriorly, apical margins rounded, with tip directed internally. Aedeagus (Fig. 13D–F): ventral wall of tegmen elongate, lateral margins convergent from apical third; apex forming a pair of short, rounded lobes with central acute tip curved ventrally; fringe of long setae along the lateral margins of tegmen dorsally; parameres very short, hidden between tegmen and median lobe; median lobe membranous, with numerous spine-like sclerites and tufts of thick pubescence. Female Similar to male; antennae (Fig. 6U) shorter; pronotum (Fig. 8J) wider, 1.5 times as wide as long, lateral margins sinuate, without notches; tarsal claws without basal lobe or apical slit; ventrite VII (Fig. 15J) with distal margin broadly arched, without projections or notches. Distribution Brazil (Minas Gerais state) (Fig. 16).Published as part of Biffi, Gabriel & Geiser, Michael, 2022, A revision of Discodon tricolor (Guérin-Méneville) and its mimics from the Atlantic forests of Brazil (Coleoptera: Cantharidae), pp. 148-189 in European Journal of Taxonomy 834 (1) on pages 173-176, DOI: 10.5852/ejt.2022.834.1907, http://zenodo.org/record/701767

Antennae (Fig. 6I) slightly flattened dorsoventrally; antennomeres III–IX wider distally, subserrate; antennomeres IX–XI slightly narrower than preceding ones. Pronotum (Fig. 7I) variable, about 1.5 times as wide as long; usually, anterior margin slightly arched, almost straight in middle, anterior angles arched; lateral margins slightly sinuate, with deep notch at posterior third; sometimes lateral margins less sinuate and lateral notches shallow; integument smooth, densely covered with very fine yellow setae. Elytra long, each elytron 4.5 times as long as wide, almost parallel, wider at middle; integument coriaceous, densely covered with short and fine decumbent setae, and much longer thick erect setae. Legs slender, densely pubescent, covered with long and thick setae; tarsi flattened dorsoventrally, fourth tarsomere with transversal slit at base; anterior prothoracic tarsal claws (Fig. 9I) broadly lobed basally, lobe with truncate margin; posterior claws on meso- and metathoracic tarsal claws apparently split at apex, with fine protruding tooth slightly shorter than claws. Abdomen weakly sclerotised, coriaceous, densely covered with long setae; ventrite VI deeply notched at posterior margin, V-shaped, lateral apices arched; ventrite VII (Fig. 10I) with broad lobes, internal and apical margins forming acute tip strongly projecting ventrally. Aedeagus (Fig. 13A–C) triangular, ventral wall of tegmen parallel at base and strongly narrowing apically, apex acute; fringe of long setae along lateral margins of tegmen dorsally; parameres robust, very long, sinuous, apices acute, convergent; median lobe short, membranous, partially retracted behind parameres; central sclerite very long and slender, curved dorsally. Female Similar to male; antennomeres (Fig. 6T) broader; pronotum (Fig. 8I) trapezoidal, wider, 1.6 times as wide as long, lateral margins sinuate, without notches; tarsal claws without basal lobe or apical slit; ventrite VI not notched, distal margin slightly arched, concave; ventrite VII (Fig. 15I) broad, lateral and distal margins broadly arched, distal margin with two apical rounded lobes projecting posteriorly at middle.
