Genus Terrylee gen. n. Broad, Sääksjärvi & Veijalainen
( Figures 1–5 View Figure 1 View Figure 2 View Figure 3 View Figure 4 View Figure 5 )
Type-species: Terrylee peruensis Broad, Sääksjärvi & Veijalainen.
Diagnosis
Terrylee is one the most distinctive genera of the subfamily Banchinae . It may easily be separated from all other banchine genera by the combination of the following characters: highly polished and shiny cuticle ( Figures 1–5 View Figure 1 View Figure 2 View Figure 3 View Figure 4 View Figure 5 ), long mandibles, with the upper tooth about three times longer than the lower tooth, wide gena, extremely narrow occiput, backward-facing “pocket” on the dorsal part of the pronotum ( Figure 2 View Figure 2 ), reduced hind wing venation and strongly upcurved ovipositor ( Figures 1 View Figure 1 , 4 View Figure 4 ).
Description
Small-sized (body length c. 3–4.4 mm, excluding ovipositor, wing length c. 3–3.8 mm) insects with highly polished and shiny cuticle, reduced hind wing venation, narrow occiput, small compound eyes, strongly up-curved ovipositor and black or dark brown, patterned orange, yellow and white ( Figures 1 View Figure 1 , 3 View Figure 3 , 4 View Figure 4 ). Clypeus evenly convex and wide, about 2.2–2.5 times as wide as high; in anterior view with margin almost transverse and with some long hairs ( Figure 5 View Figure 5 ). Malar space wide, c.0.9–1.3 times basal width of mandible. Mandible long and rather strongly tapered apically, with some long hairs and with upper tooth clearly longer (c.3 times) than lower tooth. Lower face subquadrate and weakly convex, with rather weak vertical swelling and some scattered punctures and hairs. Margins of antennal sockets raised to form round lamellae. Inner margins of antennal sockets unspecialized, about as high as other margins. Frons highly polished and very slightly concave. Eyes and ocelli small, ocellar–ocular distance about 2.5 times maximum diameter of lateral ocellus. Gena wide and shiny, about 0.05–1.0 times as broad as compound eye ( Figures 2 View Figure 2 , 4 View Figure 4 ). Occipital carina dorsally complete, its lower part joining hypostomal carina distinctly above base of mandible. Occiput very narrow. Antenna moderately slim, not whitebanded. Scape apically truncate, about 40 ◦ from transverse. Subapical flagellomeres with placoid sensilla evenly distributed. Mesosoma rather long and low, about twice as long as high, highly polished and shiny ( Figures 2 View Figure 2 , 4 View Figure 4 ). Pronotum rather long and shiny, in dorsal and lateral view with a pocket-like structure, posterior margin with rather weak swelling just opposite pocket-like structure ( Figure 2 View Figure 2 ). Epomia present, rather strongly developed and long, more or less central on pronotum. Dorsal, posterior corner of pronotum slightly twisted, partly exposing pre-spiracular sclerite. Mesoscutum convex and centrally somewhat flattened, highly polished, with some small punctures. Notauli very weakly developed and short but separating lateral lobes, or apparently absent. Mesopleurum shiny, with scattered punctures and hairs. Epicnemium with weak secondary carina near lower corner of pronotum. Sternaular region of mesopleurum weakly impressed. Epicnemial carina short, hardly reaching lower corner of pronotum, with lower part weakly sinuous. Metapleuron with submetapleural carina broadened anteriorly into relatively broad lobe. Propodeum short and fairly evenly rounded, with rather long hairs ( Figure 2 View Figure 2 ), carination varying from only pleural and posterior transverse carinae strong to pleural, posterior transverse, lateromedian longitudinal and lateral longitudinal carinae behind posterior transverse carina strong. Propodeal spiracle subcircular. Fore, mid and hind tibiae slimly clavate (outer surface subapically concave). Tarsal claws small and pectinate. Tarsomeres cylindrical. Fore wing with vein 3rs-m entirely absent. 2m-cu with a single short bulla close to M. Vein cu-a distal to base of Rs&M. Hind wing with very reduced venation, distal abscissa of Rs absent; M present only as a small stubb; distal abscissas of Cu1 and 1A absent. Tergite I, in lateral view, with spiracle positioned anterior to centre, about 0.38–0.4 of length from base, in dorsal view smooth and polished, with or without weak dorsal impression, with lateromedian longitudinal carinae present as short vestiges anteriorly. Sternite I short, not reaching back to spiracle, in lateral view forming evenly rounded, rather weak lobe ( Figure 2 View Figure 2 ). Tergite II subquadrate, with shallow but wide thyridia anteriorly. Laterotergites II–III rather narrow and turned under, laterotergites IV–V not clearly separated from their respective tergites. Female with subgenital plate moderately large and evenly but rather weakly sclerotized. Ovipositor strongly up-curved, about same length as hind tibia, apex subcylindrical, without dorsal subapical teeth or denticles, with weak subapical notch dorsally ( Figure 1 View Figure 1 ).
Etymology
Terrylee is named in honour of Dr Terry Lee Erwin, in recognition of his pioneering work on tropical rain forest canopies and for providing us with the ichneumonids of the diverse canopy fogging samples he has collected. The type species of the genus, T .
peruensis , was found from samples collected by Dr Erwin in Peruvian Amazonia. The gender of the genus name is masculine.
Remarks
We have found two species belonging to this new genus. Terrylee peruensis is only known from Peru and T. olearius from Honduras. The distribution of the genus is very interesting as there are no specimens known from Costa Rica, where the banchine fauna has recently been revised and is relatively very well known ( Gauld 2002).
