description: Glyptapanteles marcpolleti Arias-Penna, sp. nov.Fig. 151 Male. Body length 2.53 mm, antenna length 3.58 mm, fore wing length 3.0 mm. Type material. <b>Holotype</b>: ECUADOR• 1♀; EC-37478, YY-A167; Napo, Yanayacu Biological Station, Yanayacu Road; cloud forest; 2,100 m; - 0.566667, -77.866667; 10.iii.2009; CAPEA leg.; caterpillar collected in fourth instar; cocoon formed on 19.iii.2009; adult parasitoid emerged on 18.iv.2009; <i>Mesochorus</i> (Ichneumonidae: Mesochorinae) was reported as hyperparasitoid; (PUCE). Diagnosis. Hind coxa with medium-size punctate throughout (Fig. 151A, J), hind telotarsus as equal in length as fourth tarsomere, distal antennal flagellomere subequal in length with penultimate, phragma of the scutellum widely visible (Fig. 151F), propodeum medially rhomboid-shaped with transverse rugae, but no trace of median longitudinal carina (Fig. 151F), anteroventral contour of mesopleuron convex (Fig. 151A, I), edges of median area on T2 polished and followed by a deep groove (Fig. 151G, H), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a distinct stub (Fig. 151K). Coloration (Fig. 151 A–L). General body coloration polished black except scape, pedicel and all antennal flagellomeres (on both sides) brown; mandibles brown-reddish; glossa maxillary and labial palps light yellow-brown; tegulae brown. Eyes gray and ocelli reddish (in preserved specimen). Fore and middle legs light yellow-brown, except coxae medially brown with surrounded areas light brown, femora, tibiae and tarsomeres with a narrow dorsal brown strip from top to bottom, and claws brown; hind legs light yellow-brown except black coxae, femora brown, but proximally light yellow-brown, tibiae and tarsomeres brown. Petiole on T1 black and sublateral areas yellow-brown; T2 with median area black and lateral ends brown; T3 and beyond completely brown; distally each tergum with a very narrow whitish translucent band. In lateral view, T1-2 completely yellow-brown; T3-4 yellow-brown, but dorsally brown; T5 and beyond completely brown. S1-4 yellow-brown; penultimate sternum and hypopygium brown. Description. <b>Head</b> (Fig. 151 A–D). Head rhomboid with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.20:0.06, 0.25:0.06, 0.22:0.06), distal antennal flagellomere subequal in length with penultimate (0.13:0.05, 0.12:0.05), antenna longer than body (3.58, 2.53); antennal scrobes-frons sloped and forming a shelf. Distal half of face dented only laterally, punctate-lacunose, interspaces wavy and longitudinal median carina present. Frons smooth. Temple wide, punctate-lacunose and interspaces wavy. Inner margin of eyes diverging slightly at antennal sockets; in lateral view, eye anteriorly convex and posteriorly straight. POL shorter than OOL (0.10, 0.12). Malar suture present. Median area between lateral ocelli slightly depressed. Vertex laterally pointed or nearly so and dorsally wide. <b>Mesosoma</b> (Fig. 151A, E, F, I). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, interspaces smooth. Scutellum shield-shaped, apex sloped and fused with BS, but not in the same plane, scutellar punctation distinct throughout, in profile scutellum slightly convex, but on same plane as mesoscutum, phragma of the scutellum widely visible; BS only very partially overlapping the MPM; ATS demilune with short stubs delineating the area; dorsal ATS groove with semicircular/parallel carinae. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation with a smooth and shiny sloped transverse strip. Metanotum with BM convex; MPM circular without median longitudinal carina; AFM with a small lobe and not as well delineated as PFM; PFM thick, smooth and with lateral ends rounded; ATM proximally with a groove with some sculpturing and distally smooth. Propodeum medially romboid-shaped with rugae, proximal half curved rather coarse sculpture and distal half relatively polished and with a shallow dent at each side of nucha; distal edge of propodeum with a flange at each side and without stubs; propodeal spiracle distally framed by a short transverse carina; nucha surrounded by long radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum smooth, but both dorsal and ventral furrows with short parallel carinae. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove smooth, shiny and shallow, but visible; epicnemial ridge convex, teardrop-shaped. <b>Legs.</b> Ventral margin of fore telotarsus apex excavated, but without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.07). Hind coxa with medium-size punctate throughout and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.27, 0.19), entire surface of hind tibia with dense strong spines clearly differentiated by color and length; hind telotarsus as equal in length as fourth tarsomere (0.15, 0.14). <b>Wings</b> (Fig. 151K, L). Fore wing with r vein slightly curved; 2RS vein slightly convex to convex; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a distinct stub; 2M vein slightly curved/swollen; distally fore wing [where spectral veins are] with microtrichiae more densely concentrated than the rest of the wing; anal cell 1/3 proximally lacking microtrichiae; subbasal cell with microtrichiae virtually throughout; vein 2CUa absent and vein 2CUb spectral; vein 2 cu-a absent; vein 2-1A present only proximally as tubular vein; tubular vein 1 cu-a curved, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe very narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin. <b>Metasoma</b> (Fig. 151A, G, H, J). Metasoma laterally compressed. Petiole on T1with a mix of fine rugae and coarse sculpture over most of the surface, virtually parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.37, maximum width 0.20, minimum width 0.15), and with scattered pubescence on distal half. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.15, length T2 0.15), edges of median area polished and lateral grooves deep, median area broader than long (length 0.15, maximum width 0.20, minimum width 0.11); T2 with scattered pubescence throughout. T3 longer than T2 (0.20, 0.15) and with scattered pubescence throughout. <b>Cocoon.</b> Unknown. Comments. The propodeum with a transverse discontinuous carina present only laterally; proximally the propodeum with coarse sculpture, in contrast distally is polished and each lateral side has a deep dent (Fig. 151F). This species looks like <i>Parapanteles</i> because of petiole shape (parallel-sided almost throughout) and the propodeum (each side of distal half with a distinctive dent). A whole specimen was used for DNA extraction. Female. Unknown. Etymology. Marc A. A. Pollet's research is focused on biodiversity, sampling methodologies, ecology, systematics, taxonomy, phylogeny, and conservation of the long-legged flies Dolichopodidae (Diptera) in the Palaearctic and the Neotropics. Currently, he is a research manager at the Research Institute for Nature and Forest (INBO), Brussels, Belgium. Distribution. Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road), during March 2009 at 2,100 m in cloud forest. Biology. The lifestyle of this parasitoid species is gregarious. <i>Mesochorus</i> (Ichneumonidae: Mesochorinae) was reported as hyperparasitoid. Host. Undetermined species of Apatelodidae feeding on <i>Miconia</i> sp. (Melastomataceae). Caterpillar was collected in fourth instar.
