description: Madecorphnus dentatus Frolov, sp. nov.   
(Figure 13, 24, 31)  
 Type material   
 Holotype, male. Chaînes Anosyennes, SW of Trafonaomby, plateau Andohahelo, 1770–1950 m, V.1972 (MNHN). Paratype, female with the same data as the holotype. Paratype, male: NW of Fort-Dauphin, massif Andohahelo, forest Andranomangara, Integral Nature Reserve no. 11, 1750 m, 20-25.I.1974, A. Peyrieras leg.   
 Description   
 Holotype, male. Body length 6.0 mm. Colour reddish brown, head, legs, and apices of elytra somewhat darker.   
Right mandible slightly longer than left, without tooth behind of apex. Labrum trapezoidal, its length about 1/4–1/5 width (in dorsal view).  
Clypeus asymmetrical, slightly convex anteriorly, obtuse, with two long and a number of smaller setae. Genae very small, not protruding past eyes. Canthus and frontal suture indistinct. Clypeus somewhat depressed in the middle anteriorly, sparsely punctate.  
Pronotum 1.8 times wider than long, widest medially. Margins with relatively wide border, lateral margins with four long setae. Pronotum evenly convex, punctate (punctures separated by two to three puncture diameters).  
Elytra convex, with distinct humeral and apical calli. Maximum width approximately at basal third. First stria distinct and reaching the apex of elytron, other striae indistinct. Disc of elytra with sparse punctures. Epipleura with long, sparse, brown setae. Base of elytra with border from scutellum to humeral callus. Elytra minutely punctate except for a few relatively large punctures in the middle of each elytron near stria 1.  
Anterior tibiae with three outer teeth, lateral margin basad of outer teeth not crenulate. Apex with robust, spur-like seta and a few smaller setae basally. Middle and posterior legs similar in shape. Longer tibial spur as long as two basal tarsomeres in middle legs and as long as three tarsomeres in posterior legs.  
 Aedeagus. Parameres symmetrical, tapering apically in lateral view, with large teeth laterally (Figure 13). Internal sac of aedeagus with one sclerite composed of two long slender spinules connected basally (Figure 24).   
 Variability   
The paratypes are about the same size as the holotype, somewhat paler. Male paratype with shorter mandibles similar to those in female. Female, except for shorter mandibles, differs in having two setae on hind angles of pronotum and in robust protibial spur.  
 Diagnosis   
 This species can be separated from other Madecorphnus species by distinct shape of parameres and internal sac armature.
