Type material: Holotype ♂ ( MUSM): Peru, Cajamarca, provincia de Celendin, Sorochuco, El Punre , 06°59′28″S, 78°17′17″, alt. 3,652 m, 11-12.IV.2009, leg. L. Huerto. Paratypes: 1♂, 1♀, same locality and date as the holotype, leg. L. Huerto ( MUSM) ; – 19 ex., provincia de Celendin, Punre, initio de la carretera de la Mina Galeno, flowering shrubs, 06°59′51″S, 78°17′25″W, alt. 3,636 m, 05.V.2018, leg. R. Constantin; – 12♂, 4♀, provincia de Celendin, Punre 500 m S, flowering shrubs, 06°59′53″S, 78°17′07″W, alt. 3,460 m, 05.V.2018, leg. R. Constantin. Holotype and fifteen paratypes deposited in the collection of the MUSM, other paratypes preserved in author’s collection ( CCo) .

Description: Holotype. Length 5.0 mm. Head, pronotum, elytra and abdomen black. Antennae black, the second antennomere rufous brown. Mandibles yellow. Legs brown. Head 0.76 times as wide as pronotum. Eyes small, very convex, bulging, the inter-ocular space twice as wide as the length of eye. Clypeus protruding. Frons concave between the antennal sockets, flat behind. Temples short and right. Cephalic surface shiny, strongly punctate,the punctation one and a half as wide as the intervals, with sparse yellowish setae. Pronotum 1.42 times wider than long, thinly bordered all around, the lateral sides with a convex, narrow bead, the apical corners shortly bevelled and concave, the basal corners obtuse angled, not protruding. Pronotal surface irregular, shiny, strongly punctate on the disc and smaller punctations on the sides. Elytra distinctly elongate,3.4 times longer than wide basally, with trace of a single narrow costa, strongly and irregularly punctate, the punctations shallowly wrinkled, as wide as three times their intervals. Sternite VIII densely micropunctate, elongate and apically rounded. Aedeagus: tegmen with apices of lateral lobes strongly emarginated, apical angles laterally as long as wide; lateral sclerites apically wide with a preapical denticle.

Dimensions of the holotype: TL = 5.0 mm; AL = 3.9 mm; HW = 0.86 mm; IOW = 0.52 mm; OL = 0.27 mm; IAW = 0.22 mm; PL = 0.8 mm; PW = 1.14 mm; EL = 3.9 mm; EW = 1.14 mm. Length of the antennomeres, in mm: aI = 0.35; aII = 0.14; aIII = 0.33; aIV = 0.38; aV = 0.39; aVI = 0.4; aVII = 0.38; aVIII = 0.37; aIX = 0.32; aX = 0.31; aXI = 0.34. Paratype ♂: length 4.3 mm.

Paratypes ♀: Differ from the males by the smaller eyes and shorter antennae. Sternite VIII densely micropunctate, short and wide, the apical edge deeply incised in

the middle. Dimensions ♀. TL = 4.4 mm; AL = 2.7 mm; HW = 0.73 mm; IOW = 0.5 mm; OL = 0.21 mm; IAW = 0.21mm;PL= 0.66mm;PW= 1.07mm;EL = 3.3 mm; EW = 1.06 mm.

Differential diagnosis: Plectonotum huertoae sp. nov., is similar to the Peruvian species P. longissimum ( Pic, 1927) by the elongate elytra, and differs of the latter by the smaller size, shiny surface, stronger and less dense pronotal punctation, and different aedeagus shape.

Etymology: Respectfully dedicated to Luz Maria Huerto Santillá, biologist and entomologist at the MUSM, specialist of Diptera , Tephritidae . L. M. Huerto was the collector of the first three type specimens in this interesting site during inventories field works.
