9 Remarks: In two specimens without gender indication the gender could not be determined with certainty. The specimens have an empty hind cavity, obviously resulting from a mounting attempt of a former researcher.

DIAGNOSIS. A sturdy looking big sized species, with maximum width of the elytra behind middle, with pronotum distinctly transverse and shaped in dorsal view like a wider bowel, and lateral margin distinctly crenulated and convex in its whole length, and the surface covered with small coreaceate-like meshes, fine granula and indistinct reticulation. The transverse costa at the neck is distinctly convex, the eyes are distinctly globose, and the lateral margin of the supraantennal plates are distinctly convex. Beside the transverse shape of the pronotum, the most distinguishing characters from the other species are the body size (it is the largest species of the genus) with the costae on the frons and the head showing a different colour. In addition the mentum shows a light emargination only, and the tip of the aedeagus is shaped like half of a spoon with distinctly crenulated margin.

REDESCRIPTION.

Measurements: Body length 4.08–4.91 mm (0 = 4.51 mm *), width 1.30–1.51 mm (0 = 1.41 mm *), ratio length/width of pronotum 0.69–0.73 (0 = 0.71*), ratio length/width of elytra 1.64–1.77 (0 = 1.69*); (*n = 10).

Colour: Head opaque, costae on frons glossy; pronotum semi-opaque, body and legs shiny. Uniformly ferrugineus with brunneus tinge, slightly darker at base of elytra, in a few specimens with a slightly brownish indistinct and unclear spot at middle of the elytra, lateral margins and front legs darker, costae on frons fuscous, antennae flavus; supraantennal plates translucent flavus, mandible piceous apically.

Head: A fifth narrower than pronotum. Clypeus with short longitudinal costa at middle, with two projecting tubercles anteriorly, wings broad, surface smooth, each with a projecting tubercle on each wing, as advanced as tubercles of clypeus, separated from clypeus by a costa at each side, tubercles of clypeus and wings convex on top; supraantennal plates wide, laterally convex, margins distinctly reflexed; supraantennal plates with conspicuous costae running from clypeal wing slightly beyond mid-eye level. Frons with six conspicuously raised longitudinal costae, two of which run paramedian in parallel from neck to clypeus, with a second pair of costae running laterally to the central costae from the neck distinctly beyond mid-eye level, distinctly converging anteriorly and indistinctly adjoining the central costae, with a third shorter pair of costae located laterally at anterior-eye level each in parallel to the costae of the supraantennal plates, distinctly interrupted posteriorly. Supraorbital setae located at posterior-eye and neck level. Neck composed of a transverse conspicuously raised distinctly convex costa, not joined with other costae. Surface of head covered with distinct isodiametric reticulation. Eyes globose, raised laterally more than 2x as high as supraantennal plates. Genae indistinct. Antenna of moderate length, reaching up to basal constriction of pronotum, segments five to ten distinctly longer than wide. Labrum slightly bilobed and convex anteriorly, with irregular to isodiametric reticulation, seven-setose. Mandible moderately long, straight at middle part, arcuate nearly hook-like at apex, reflexed margined. Apical segment of maxillary palpomere elongate, securiform, pointed at apex, terminal segment of labial palpomere bottle like, slender apically. Mentum quadridentate apically, slightly excised between teeth, lateral lobes with broad carina, surface slightly coreaceate, central tooth obtuse, separated from lateral lobes with slight emargination.

Pronotum ( Figs 3 , 11): Convex on disc (lateral view). Distinctly convex in frontal view. Outline shaped in dorsal view like a wider bowl, transverse, wider than long. Lateral margin regularly convex. Anterior angles broadly rounded off by reflexed lateral margin. Reflexed lateral margin distinctly crenulated. Lateral channel distinctly wide from anterior angle to

10 posterior angle, separated from disc by a carina. Anterior setigerous puncture situated in marginal channel, posterior puncture removed from channel by diameter of pore. Posterior angle marked by a small tooth. Pleura somewhat swollen, visible in dorsal view. Anterior margin slightly excised. Anterior transverse line wide, not reaching anterior angle, with conspicuous transverse carina between anterior margin and anterior transverse line, distinctly interrupted at middle. Median line wide, valley-like, joining with anterior transverse line and basal constriction, bilaterally with carina in anterior part. Basal constriction of moderate size, flange with sharp carina. Disc somewhat opaque, with small coreaceate-like meshes, fine granula and reticulation, in few specimens with indistinct paralateral impression parallel to lateral channel.

Elytra ( Fig. 3 ): Slightly transversally depressed in anterior third (lateral view). Subelongate, sides moderately convex, maximum width at middle. Base truncated nearly straight. Marginal channel moderately wide, running over rounded humerus up to level of sixth interval, series of umbilical setigerous punctures not interrupted. Reflexed margin smooth. Humeral tooth small but distinct. Striole distinct, elongated. Basal tubercle with setigerous puncture distinct, situated at declivity of first stria, tubercle at declivity of interval three distinct. Striae one to four free at base, all striae deep, indistinctly punctuate-striate (punctuation nearly invisible). Intervals distinctly convex, carinate apically. Interval three with four setigerous punctures, all approaching stria three. Surface of intervals irregularly reticulated but glossy, with transverse rugae.

Hind wings: Fully developed.

Ventral description: Proepisternum with isodiametric reticulation, pleura somewhat swollen postero-laterally. Prosternum smooth, shiny. Abdomen smooth, shiny, laterally with isodiametric reticulation. Last five abdominal sternites with two rows of setae. Abdominal sternum with the two bigger marginal setae separated.

Legs: Profemur dorsally covered densely with transverse parallel wrinkles and isodiametric reticulation, ventrally with eight transverse carinae. Protibia with the three upper spines elongated, the basal one shorter and rounded off, surface with isodiametric to longitudinal reticulation, movable apical spur shorter than terminal spine, spur and spines not sharp, rounded apically, basal tarsomere nearly as long as tarsomeres two to five together. Mesotibia without preapical spine, with four strong setae distally arising from tubercles.

Male genitalia (Fig. 17): Median lobe moderately slender, in dorsal view moderately arcuate in basal third and towards apex, nearly straight but slightly distorted in lateral view, tip of apex widened, obtusely truncated in dorsal view, rounded spoon like in lateral view, crenulated apically. Oroficium relatively small. Internal sac with group of bristles, strongly folded apically. Parameres moderately slender, without much distortion, both of them with one long seta at apex, the dorsal one with an additional pilus at apex.

Female genitalia (Fig. 23): Coxostyli slender, hyaline, bottle-like shaped, with three long nematiform setae in the middle part and with one minute pilus at tip of apex.

Variation: The most striking variability was observed in the intensity of coloration and size of the brownish unclear spot at middle of the elytra observed in a few specimens. The reflexed lateral margin of the elytron exhibits in some specimens indistinct blunt scars. The transverse rugae on the intervals of the elytra show some variability in distinctness. Few specimens show a very indistinct paralateral impression parallel to lateral channel of the pronotum.

DISTRIBUTION: Known from Maroantsetra which is located in the North-East of Madagascar. The record “Saint-Augustin, près de Tuléar” and the mark in the map in BASILEWSKY (1973, p. 247 FIG. 107 and text p. 251) refers to another species ( L. hanoti sp. nov.).
