Type material: Holotype ♂ ( MUSM): Peru, Cajamarca, provincia de Santa Cruz de Succhabamba, Pulán, Caserio de Zanja , 78°55′11.7″W, 06°49′17.0″S, 3,457m, 12.IX.2012, leg. I. Medina. GoogleMaps

Description: Holotype. Length 3.5 mm. Head black. Mandibles fulvous yellow.Palpi brown.Antennae, pronotum and abdomen black.Elytra pitchy brown. Legs black, tibiae yellowish brown, tarsi brown. Head 0.77 times as wide as pronotum. Eyes short, convex, bulging. Frons feebly depressed between the eyes, with two small shallow oblique retro-antennal dimples. Cephalic surface dull, with marked punctation, the punctation as wide as their intervals, covered with thin yellowish, sparse setae. Temples short, narrowed basally. Antennae slender, longer than four fifths of body length. Pronotum 1.33 times wider than long. Anterior edge right, basal edge weakly arched, side edges rounded, more narrowing anteriorly than posteriorly, front and rear angles obtuse. Disc wide, moderately convex, separated from the border by a marked furrow with about fifty deep punctations. Lateral borders basally wider and more explanate than the front and rear borders. Elytra 2.55 times longer than their combined width at the base, not costate, subseriately and strongly punctate, the punctations twice wider than their intervals, covered with sparse, long (0.1 mm), stiff, yellowish setae, obliquely backwards directed. Legs simple, tarsi rather elongate, the metatarsi about three quarters of metatibial length, the claws thin, without basal denticles. Abdominal sternite VIII subquadrate, the apical edge truncate, laterally rounded. Aedeagus: tegmen elongate, apically wider, the apico-ventral edge with two long, narrow processes. Lateral sclerites slen- der, not denticulate. Median lobe with narrow tip.

Dimensions of the holotype: TL = 3.5 mm; AL = 3.05 mm; HW= 0.81mm;IOW= 0.56mm;OL= 0.2mm;IAW= 0.22mm;

PL = 0.78 mm; PW = 1.04 mm; EL = 2.55 mm; EW = 1.0 mm. Length of the antennomeres, in mm: aI = 0.25; aII = 0.12; aIII = 0.25; aIV = 0.32; aV = 0.34; aVI = 0.34; aVII = 0.33; aVIII = 0.32; aIX = 0.28; aX = 0.28; aXI = 0.28.

Differential diagnosis: Hyponotum succhabamba sp. nov., is similar to the Chilean H. philippii Gemminger, 1870 by the size and body colour pattern and differs from the latter by the subseriately and coarsely punctate elytra, covered with semi-erected, either short or long, whitish setae and by the pronotal margins entirely furrowed.

Etymology: The specific epithet is related to the province name of the type locality.

Hyponotum philippii ( Gemminger, 1870) ( Figs. 23 View Figures 17-23 , 46 View Figures 36-46 , 91-92 View Figures 79-92 , 115 View Figures 110-115 , 119 View Figure 119 )

Material examined: Paratype ♂ ( NHMB):“Stgo.[Santiago de Chile], 31.VIII.1939, paratype ” [of Plectonotum kuscheli Wittmer ], leg. G. Kuschel ; Santiago Chile, 07.X.1945, leg. W. Wittmer (1♂ NHMB) ; Chile, reg. IX, prov. Cautin , 30 km NE Villarica, 19-31.XII.1964, leg. L. Peña (1♂ NHMB) .

This species is distributed in central and south Chile and included here for comparison with the Peruvian species. It was described as Thelephorus praecox Philippi & Philippi, 1864 (lapsus for Telephorus ), and became a secondary homonym of Cantharis praecox Géné, 1836 when Telephorus Schaeffer, 1766 , was synonymized with Cantharis Linnaeus, 1758 . The taxon was then renamed as Telephorus philippii by Gemminger (1870). Wittmer (1948) transferred Cantharis praecox ( Philippi & Philippi, 1864) to Chauliognathus Hentz, 1830 , probably anaware of the replacement name proposed by Gemminger (1870). Wittmer (1945) described Plectonotum kuscheli as a new species,but subsequently ( Wittmer, 1957) recognized it as a synonym of Hyponotum praecox ( Philippi & Philippi, 1864) . The current and valid name for the species is therefore Hyponotum philippi ( Gemminger,1870) (see ICZN, 1999,article 59.3).
