Phradis wolfgator sp. n.

Figs 5, 10 , 14, 18, 20, 22

Etymology: From the type locality.

Diagnosis: The new species is distinguished from all the known species of Phradis by the yellow pterostigma, almost entirely smooth head and mesonotum, densely punctate mesopleuron, and shape and coloration of the hind tibia ( Fig. 22 ).

Description:

Female.

Body length 3.3 mm.

Head 0.74 mm wide, strongly and roundly narrowed behind eyes in dorsal view; temple almost as long as eye width ( Fig. 14 ). Ocelli small. Antenna filiform; flagellum with 11 segments, very slender, basal segments broadened apically ( Fig. 18 ). Mandible punctate basally, upper tooth longer than lower tooth. Malar space distinctly shorter than basal width of mandible. Head predominantly smooth (frons very finely granulate); upper half of clypeus, face and frons distinctly and more or less densely punctate, vertex and temple finely and sparsely punctate. Occipital carina complete.

Mesonotum mostly smooth, finely granulate and distinctly punctate anteriorly and medially. Notaulus weak. Mesopleuron strongly prominent, very coarsely and densely punctate (distances between punctures shorter than diameter of puncture), partly punctato-rugulose, finely granulate to smooth between punctures. Sternaulus situated in anterior part of mesopleuron, about half as long as mesopleuron. Dorsolateral area of propodeum smooth anteriorly, granulate to irregularly rugulose laterally and anteroposteriorly; basal furrow distinctly elongate, widened anteriorly ( Fig. 5 ); spiracle round, separated from pleural carina by 1.5–1.8 diameters of spiracle; apical area round anteriorly, with median longitudinal depression, coarsely irregularly rugulose, its longitudinal carinae developed posteriorly and indistinct anteriorly (not reaching transverse carina).

Forewing length 2.6 mm. Pterostigma distinctly wider than length of first section of radial vein. Metacarp very short, slightly projecting beyond the radial vein ( Fig. 20 ). Second recurrent vein interstitial, unpigmented anteriorly.

Hind femur length 0.63 mm, maximum width 0.18 mm. Hind tibia length 0.72 mm, distinctly longer than hind femur, curved apically ( Fig. 22 ). Hind spurs relatively long, distinctly curved apically.

First tergite length 0.72 mm, posterior width 0.22 mm. First tergite smooth dorsally and partly striate laterally. Second tergite length 0.36 mm. Thyridia very short, transverse. Ovipositor slender, evenly upcurved, without teeth; its sheath 1.2 mm, about 1.7 times as long as first tergite.

Body mainly black, metasoma behind first segment with brownish tinge. Labial palpi and mandibles (except teeth) yellow-brown. Base of antenna and clypeus in its lower part brownish. Maxillary palpi darkened.Tegula strongly darkened. Pterostigma yellow, veins light brown. Legs strongly darkened (to black); femora apically, and tibiae basally and apically (fore tibia almost entirely) yellow-brown.

Male.

Similar to female. Flagellum of antenna with 13 segments; basal flagellomeres shorter. Malar space shorter than in female. Basal furrow of propodeum narrow, not widened posteriorly, bordered by carinae laterally.
