Description

Size range (including rostrum): Holotype male: 7.8 mm, Paratypes: 7.3–7.9 mm.

Habitus ( Figs 2 and 4 ), body black.

Head wide; rostrum as long as wide, rostral dorsum flat and shiny, punctate-striolate; impressed behind V-shaped epistome; frons twice as wide as rostral dorsum between insertions of antennae, with small puncture-like fovea; scrobes short; pterygia well pronounced, rostrum at level of pterygia narrower than width of head at level of eyes.

Antennae: Scape short and robust, weakly widening towards tip, of about twice its width at apex; first and second funicular segments of same length, 1.2 longer than wide; third to seventh globular, club fusiform.

Pronotum moderately transverse (length/width: 0.75–0.8), widest just before midlength, hind margin wider than anterior one. Mainly tuberculate, tubercles flattened, some (especially lateral ones) umbilicate with very scarce, bowed, brownish bristles, at disc punctuate, surface shining, without microsculpture.

Elytra (length/width 1.42–1.46) long-oval, widest just before midlength, without shoulders and laterally regularly rounded towards base. Striae very shallow, hardly visible, small sharp punctures spread over elytra; tiny, hardly visible bowed brown bristles arise from punctures (best visible at elytral declivity). Outer intervals with rasp-like punctures appearing as pointed microscopic tubercles. Surface of elytra chagrinated, thus appearing more dull than shiny pronotum.

Legs very robust, protibiae not dilated outwards, apex of metatibiae in males thornlike prolonged; tarsi very robust.

Genitalia: penis parallel-sided from basal third up to apex, apex truncate with faint depression in middle; in lateral view weakly bowed, almost straight ( Figs 4A–B ). Transfer apparatus consisting of four twisted sclerites ( Fig. 4C ). Female sternite VIII very robust and entirely strongly sclerotized, plate roundish, apical margin straight and set with hairs ( Fig.

5 4D). Spermatheca with long and narrowly bowed cornu, and short globular nodulus and ramus ( Fig. 2E ). Ovipositor rather simple, very robust and strongly sclerotized, torpedoshaped ( Fig. 4F ). Apex inconspicuous (without long styli nor bristles), apical half with numerous sensorial grooves.

Sexual dimorphism: elytra of males narrower and shorter than those of the female; legs in males stronger, tarsi – especially third bilobed segment and strongest pronounced in protibiae – broader, almost twice as wide as in females; apex of hind legs longer thorn-like prolonged in males ( Figs 3 A-B).

Derivation of name: The new species is named after Dr. h. c. Werner Marggi, scientific collaborator at the NMBE, esteemed colleague and renowned carabidologist. We collected together on numerous excursions, and worked together in the field on Carabidae , I could always count on Werner's exceptionally rich and broad knowledge and experience in entomology.

Ecology: The new species was collected together with similar black and shiny Carabidae under stones on Alpine meadows above 2300 m a.s.l.
