Madecorphnus punctatus Frolov, 2010

( Figs. 16 View FIGURE 16 A–G)

Madecorphnus punctatus Frolov, 2010c: 1104 .

Type material examined. Holotype ( Figs. 16 View FIGURE 16 A–F), male, “ MADAGASCAR CENTRE Est du lac Mantasoa, frt Ambohiboatavo 1340 m, III.1973 P. Griveaud et A. Peyrieras / Holotypus Madec. punctatus Frolov 2009 ” ( MNHN) .

Paratypes: two males with the same locality data as the holotype.

Diagnosis. This species can be separated from other Madecorphnus species by the densely pubescent head and pronotum and by the shape of the parameres and internal sac armature.

Description. Male. Body length 4.5–5.0 mm. Head and pronotum dark brown, elytra and legs brown ( Fig. 16 View FIGURE 16 A).

Right mandible as long as left, without tooth basad of apex. Labrum trapezoidal, length about 1/4–1/5 width (in dorsal view).

Frontoclypeus symmetrical, slightly convex anteriorly, obtuse, with 2 long and a number of smaller setae. Frontoclypeus, slightly depressed in the middle anteriorly, rather densely, irregularly punctate (punctures separated by 1–3 puncture diameters) ( Fig. 16 View FIGURE 16 B).

Pronotum 1.8 times wider than long, widest medially. Margins with relatively wide border, lateral margins with 4 long setae. Pronotum evenly convex, densely, irregularly punctuate (punctures separated by 1–3 their diameters anteriorly, becoming sparser basally).

Elytra convex, with distinct humeral and apical tubercules. Maximum width approximately at basal 1/3. First stria distinct and reaching the apex of elytron, other striae indistinct. Epipleura with long, sparse, brown setae. Base of elytra with border from scutellum to humeral callus. Elytra sparsely punctate with relatively large punctures (more densely near suture).

Protibiae with 3 outer teeth, lateral margin basad of outer teeth not crenulate. Apex with robust, spur-like seta and a few smaller setae basally. Mesothoracic and metathoracic legs similar in shape. Longer tibial spur a bit shorter than 2 basal tarsomeres in mesothoracic legs and a bit shorter than 3 tarsomeres in metathoracic legs.

Parameres tapering apically, somewhat arrow shaped, angulate laterally ( Fig. 16 View FIGURE 16 C). Internal sac with 3 large sclerites and an area of short spinules ( Figs. 16 View FIGURE 16 E, F).

Female unknown.

Variation. Except for body size variation, the examined specimens are similar.

Distribution and habitat. Madecorphnus punctatus is known from one locality in central Madagascar ( Fig. 16 View FIGURE 16 G).
