Glyptapanteles suzannegreenae Arias-Penna, sp. nov. Fig. 211

Female.

Body length 3.18 mm, antenna length 3.98 mm, fore wing length 3.83 mm.

Type material.

Holotype: ECUADOR • 1♀; EC-7074, YY-A217; Napo, Yanayacu Biological Station, Comedor Susanita (Loreto), Plot 93; cloud forest; 1,009 m; - 0.7, -77.733333; 10.ix.2005; Drew Townsend leg.; caterpillar collected in second instar; cocoon formed on 07.x.2009; adult parasitoid emerged on 23.x.2005; ( PUCE).

Diagnosis.

Face punctate-lacunose ( Fig. 211B ), distal antennal flagellomere longer than penultimate, scutellum in profile slightly convex, but on same plane as mesoscutum ( Fig. 211J ), petiole on T1 distally with lateral margins convex ( Fig. 211H ), mesoscutum punctation proximally distinct, but distally absent/dispersed ( Fig. 211F ), dorsal furrow of pronotum with a well-defined smooth band ( Fig. 211C, J ), precoxal groove deep, smooth and shiny ( Fig. 211A, J ), dorsal carina delimiting a dorsal furrow on propleuron absent ( Fig. 211C ), petiole on T1 parallel-sided but narrowing at apex ( Fig. 211H ), anteroventral contour of mesopleuron straight/angulate or nearly so ( Fig. 211A, J ), edges of median area on T2 polished and followed by a deep groove ( Fig. 211H, I ), and fore wing with r vein curved, outer side of junction of r and 2RS veins forming a slight stub ( Fig. 211L ).

Coloration

( Fig. 211 A–M ). General body coloration satin black except pedicel brown-reddish distally with a brown ring; scape yellow-brown; all antennal flagellomeres brown on both sides; labrum and mandibles yellow-brown; maxillary and labial palps, and tegulae yellow; clypeus brown-red/reddish. Eyes and ocelli silver. Fore middle and legs dark yellow except brown claws; hind legs dark yellow except black coxae distally yellow, femora distally brown, distal 1/3 of tibiae brown and proximally with a brown band, and tarsomeres brown, although basitarsus proximally with a yellow ring. Petiole on T1 dark yellow, however, laterally distal half with light yellow-brown tints, contours brown, and sublateral areas light yellow; T2 with median area with two colorations: 1/3 proximal yellow-brown and 2/3 distal brown, and lateral ends yellow; T3 mostly brown, but distally with a wide yellow band, and lateral ends yellow; T4 and beyond completely dark brown; distally each tergum with a wide yellow transparent band. In lateral view, T1-3 yellow; T3 and beyond yellow, but dorsally brown, the extent of that brown area remaining relatively constant from proximal to distal. S1-5 yellow; hypopygium brown.

Description.

Head ( Fig. 211 A–D ). Head triangular with pubescence long and dense. Proximal three antennal flagellomeres longer than wide (0.25:0.09, 0.27:0.09, 0.26:0.09), distal antennal flagellomere longer than penultimate (0.17:0.07, 0.14:0.07), antenna longer than body (3.98, 3.18); antennal scrobes-frons shallow. Face convex, 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, 0.13). Malar suture present. Median area between lateral ocelli without depression. Vertex laterally pointed or nearly so and dorsally wide.

Mesosoma ( Fig. 211A, F, G, J ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation proximally distinct, but distally absent/dispersed, interspaces smooth. Scutellum triangular, 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 completely concealed; BS mostly overlapping the MPM; ATS demilune almost smooth; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation depressed centrally and with same kind of sculpture as mesoscutum. Metanotum with BM convex; MPM semicircular without median longitudinal carina; AFM without setiferous lobes 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 without median longitudinal carina, proximal half curved with medium-sized 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 without distal carina; nucha surrounded by very short 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 finely sculptured only ventrally and dorsally without a carina. Metasternum convex. Contour of mesopleuron straight/angulate or nearly so; precoxal groove deep, smooth and shiny; epicnemial ridge widen.

Legs ( Fig. 211A ). Ventral margin of fore telotarsus slightly excavated and with a tiny curved seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.15, 0.08). Hind coxa finely punctate throughout, and dorsal outer depression present. Inner spur of hind tibia longer than outer spur (0.49, 0.34), entire surface of hind tibia with dense strong spines clearly differentiated by color and length.

Wings ( Fig. 211L, M ). Fore wing with r vein slightly curved; 2RS vein straight; r and 2RS veins forming a weak, even curve at their junction and outer side of junction forming a slight 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; veins 2CUa and 2CUb completely spectral; vein 2 cu-a present as spectral vein, sometimes difficult to see; vein 2-1A proximally tubular and distally spectral, although sometimes difficult to see; tubular vein 1 cu-a straight, incomplete/broken and not reaching the edge of 1-1A vein. Hind wing with vannal lobe narrow, subdistally and subproximally straightened, and setae evenly scattered in the margin.

Metasoma ( Fig. 211A, H, I, K ). Metasoma laterally compressed. Petiole on T1 finely sculptured only laterally, virtually parallel-sided over most of length, but barely narrowing at apex, apex truncate (length 0.42, maximum width 0.26, minimum width 0.20), and with scattered pubescence on distal half only laterally. Lateral grooves delimiting the median area on T2 clearly defined and reaching the distal edge of T2 (length median area 0.20, length T2 0.20), lateral grooves deep, median area broader than long (length 0.20, maximum width 0.28, minimum width 0.13); T2 with scattered pubescence only distally. T3 longer than T2 (0.26, 0.20) and with pubescence more notorious in distal half. Pubescence on hypopygium dense.

Cocoons ( Fig. 211E ). White or beige oval cocoon with ordered silk fibers, but covered by a net.

Comments.

The body is stout as well as the hind coxae ( Fig. 211A ), the limit between the mesopleuron and the metasternum with a flattened area, the petiole on T1 with lateral margins sinuous and distally curved (convex, Fig. 211H ), and the hind telotarsus and fourth tarsomere are missing in the holotype.

Male.

Unknown.

Etymology.

Suzanne Rab Green’s research is focused upon Arctiinae, the tiger moths. Her major fields are general systematics, biodiversity, and biogeography. She is a curatorial assistant at American Museum of Natural History, New York, NY, USA.

Distribution.

Parasitized caterpillar was collected in Ecuador, Napo, Yanayacu Biological Station (Comedor Susanita -Loreto), during September 2005 at 1,009 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Pyralidae feeding on Miconia sp. ( Melastomataceae ). Caterpillar was collected in second instar.
