Description.

Head ( Fig. 133A, C, E, F ). Head triangular with pubescence long and dense. Proximal first antennal flagellomere longer than wide (0.24:0.08), distal antennal flagellomere longer than penultimate (0.14:0.06, 0.09:0.06); antennal scrobes-frons shallow. Face flat or nearly so, punctations barely noticeable, interspaces smooth and longitudinal median carina present. Frons smooth. Temple wide, punctations barely noticeable and interspaces clearly smooth. 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 slightly depressed. Vertex laterally rounded and dorsally wide.

Mesosoma ( Fig. 133A, G, H, J ). Mesosoma dorsoventrally convex. Distal 1/3 of mesoscutum with lateral margin slightly dented, punctation distinct throughout, interspaces smooth. Scutellum triangular, apex sloped and fused with BS, but not in the same plane, scutellar punctation scattered throughout, in profile scutellum flat and on same plane as mesoscutum, phragma of the scutellum completely concealed; BS mostly overlapping the MPM; ATS demilune entirely covered by parallel carinae; dorsal ATS groove with carinae only proximally. Transscutal articulation with small and heterogeneous foveae, area just behind transscutal articulation nearly at the same level as mesoscutum (flat) and with same kind of sculpture as mesoscutum. Metanotum with BM convex; MPM semicircular and bisected by a 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, distal half slightly rugose; distal edge of propodeum with a flange at each side and short stubs; propodeal spiracle distally framed by faintly concave/wavy carina; nucha surrounded by long radiating carinae. Pronotum with a distinct dorsal furrow, dorsally with a well-defined smooth band; central area of pronotum and dorsal furrow smooth, but ventral furrow with short parallel carinae. Propleuron with fine punctations throughout and dorsally without a carina. Metasternum convex. Contour of mesopleuron convex; precoxal groove indistinct, smooth and shiny; epicnemial ridge widen.

Legs. Ventral margin of fore telotarsus entire without seta, fore telotarsus almost same width throughout and longer than fourth tarsomere (0.12, 0.08). Hind coxa finely punctate throughout, and dorsal outer depression absent. Inner spur of hind tibia longer than outer spur (0.25, 0.22), 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, 0.15).

Wings ( Fig. 134L, 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 distinct stub; 2M vein straight; 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 tubular throughout; tubular vein 1 cu-a straight and complete, but junction with 1-1A vein spectral. Vannal lobe in hind wing very narrow, subdistally and subproximally straightened, and setae absent proximally, but scattered distally.

Metasoma ( Fig. 133A, I, K, L ). Metasoma laterally compressed. Petiole on T1 with a mix of fine rugae and punctate sculpture over most of the surface, virtually parallel-sided over most of length, but barely narrowing over distal 1/3, apex truncate (length 0.41, maximum width 0.24, minimum width 0.13), 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 0.18, length T2 0.18), edges of median area polished and lateral groove deep, median area broader than long (length 0.18, maximum width 0.28, minimum width 0.12); T2 with scattered pubescence throughout. T3 longer than T2 (0.24, 0.18) and with scattered pubescence throughout. Pubescence on hypopygium dense.

Cocoon ( Fig. 133B ). White oval cocoon with messy/disordered/fluffy silk fibers, although sometimes evenly smooth.

Comments.

The median area on T2 with noticeable rugae throughout; the pubescence are all over the entire surface of T2; the hind telotarsus and fourth tarsomere are missing in holotype. The females have long ovipositor as Sathon .

Male

( Fig. 134 A–M ). Similar in coloration to female.

Etymology.

John O. Stireman III’s research is focused on tritrophic interactions, speciation, adaptive radiation, insect biodiversity, insect community structure, biology/systematics of Tachinidae ( Diptera ), plant-insect interactions, parasitoid biology and behavior. Currently, he is on the faculty at Wright State University, Dayton, OH, USA.

Distribution.

Parasitized caterpillars were collected in Ecuador, Napo, Yanayacu Biological Station (Yanayacu Road, Papallacta, and Río Chalpi Grande), during June, August, and October 2005 at 2,112 m, 2,768 m, and 2,876 m in cloud forest.

Biology.

The lifestyle of this parasitoid species is solitary.

Host.

Undetermined species of Pyralidae feeding on Urtica sp. ( Urticaceae ) and undetermined species of Apiaceae . Undetermined species of Lepidoptera feeding on undetermined species of Urticaceae . Caterpillars were collected in first, second and late instar or prepupal.
