Metrobates sanciprianensis View in CoL sp. nov.
( Figs. 1a View FIGURE 1 , 2a View FIGURE2 , 3a View FIGURE 3 , 4a View FIGURE 4 , 5 View FIGURE 5 )
Description. Apterous male ( Fig. 1a View FIGURE 1 ): measurements, holotype / paratype (n= 2): Body: length 3.62; maximum width 1.75. Head: length 0.37, width 0.60, interocular distance 0.42. Lengths of antennal segments I–IV 1.30, 0.47, 0.27, 0.35. Rostrum length 0.60. Thorax: pronotum length 0.40. Legs: leg segment lengths (femur, tibia, tarsomere I, tarsomere II): foreleg 1.30, 0.87, 0.12, 0.40; midleg 3.0 5, 5.61, 0.80, 1.05; hindleg 5.0 5, 1.45, 0.13, 0.35.
Color. Head black with a V-shaped interocular reddish brown stripe ( Fig. 1a View FIGURE 1 ). Antennal segment I with basal quarter reddish brown and distal three quarters dark brown; antennal segments II–IV brown with golden pubescence. Pronotum black with a light green patch medially, which is wider anteriorly. Mesonotum black, bluish gray medially, and a longitudinal light green stripe on each side, stripe not covering anterior region of mesonotum and completely reaching mesoacetabulum; mesopleuron black. Metanotum and mediotergite I black with a bluish grey patch on each side. Thorax bluish gray ventrally. Fore femur with basal region reddish brown, distal region black; fore tibia and tarsus black. Mid- and hindlegs black. Mediotergites II–V black with bluish gray patches covering most of its surface; mediotergite VI with a central bluish grey patch. Laterotergites I and II black with light green patches, remaining segments black.
Structure. Antennal segment I slightly narrower basally with a row of long and erect setae ventrally. Antennal segments II and III each with a small apical tuft of short, erect setae. Rostrum reaching anterior margin of mesosternum. Pronotum with a medial depression and enclosed by posterolateral angles of eye and medioanterior angles of mesonotum. Mesonotum with a median longitudinal suture. Mesoacetabulum in ventral view with a long tooth-shaped projection ( Fig. 2a View FIGURE2 ). Mesosternum with a median longitudinal suture. Metanotum with posterior margin sinuous. Fore tibia with a row of short and erect setae on lateral margin and with an apical triangular projection. Mediotergite I as long as metanotum; mediotergite VIII three times longer than mediotergite VII, narrowed and rounded distally. Paramere long with a concavity in the basal fourth and widended medially, the apical region gradually tapering to a narrow point ( Fig. 3a View FIGURE 3 ). Vesica: auxiliary basal sclerite visibly narrowed medially ( Fig. 4a, b View FIGURE 4 ); dorsal sclerite elongated and angled downwards anteriorly ( Fig. 4b View FIGURE 4 ); lateral sclerite reduced at base and widended medially, with distal region pointed and directed towards center in dorsal view and hookshaped in lateral view ( Fig. 4 a, b View FIGURE 4 ).
Apterous female measurements, paratypes (n=4): Body: length 4.0 0, maximum width 2.28. Head: length 0.50; width 0.68; interocular distance 0.46. Lengths of antennal segments I–IV: 1.14, 0.48, 0.29, 0.37. Rostrum length 0.78. Thorax: pronotum length 0.42. Leg segments lengths: (femur, tibia, tarsomere I, tarsomere II): foreleg 1.52, 1. 0 6, 0.15, 0.52; midleg 3.25, 5. 85, 0.82, 1.31; hindleg 5.3, 1.65, 0.15, 0.49.
Similar to the male in color and structure, but differs by: antennal segment I slightly narrower basally without setae ventrally. Antennal segments II and III without a small apical tuft of short and erect setae. Mesoacetabulum in ventral view without a tooth-shaped projection. Fore tibia with a row of short setae on lateral margin and without an apical triangular projection.
Material examined. Holotype: 1 apterous ♂. COLOMBIA. Valle del Cauca: Buenaventura, San Cipriano , Qda. San Cipriano . 14.v.2005, J. Rivera leg. ( UPTC-MHN-ART 0074 ) . Paratypes: 3 apterous ♀. COLOMBIA. Valle del Cauca: Buenaventura, San Cipriano, Qda. San Cipriano. 14.v.2005, J. Rivera leg. (UPTC-MHN-ART 0075). 1 apterous ♂ 1 apterous ♀. Buenaventura, San Cipriano, Vereda Tutunendo, Quebrada La Canoa. 08.xii.2015, F. Molano leg. (UPTC-MHN-ART 0029).
Etymology. The term sanciprianensis refers to the name of the region (San Cipriano Municipality) where the type series was collected.
Diagnosis. The new species resembles M. fugientis but differs in the color, the shape of the male paramere and the lack of a spine in the fore femur. In M. sanciprianensis the mesonotum, metanotum and mediotergites present bluish gray stripes ( Fig. 1a View FIGURE 1 ), whereas M. fugientis presents light green stripes ( Fig. 1c View FIGURE 1 ). The male paramere of M. sanciprianensis has a concavity in the basal fourth and is widended medially ( Fig. 3a View FIGURE 3 ), whereas M.fugientis has the concavity closer to the middle region ( Fig. 3c View FIGURE 3 ). Moreover, M. sanciprianensis does not present a spine in the fore femur as does M. fugientis ( Fig. 1d View FIGURE 1 ).
Distribution. Metrobates sanciprianensis sp. nov. is known only from the Department of Valle del Cauca ( Fig. 5 View FIGURE 5 ).
