Psyttalia masneri

Description. Female (Fig. 20). Head (Figs 16–18, 23): Frons, vertex, occiput, and gena polished; frons weakly punctate and setose along eye margin, otherwise as in halidayi; gena distinctly striate ventrally, laterad malar sulcus; face heavily sculptured, with deep punctures coalescing to form somewhat transverse rugae. Face 1.4–1.6 × wider than high. Width of ocellar field 1.3–1.4 × distance from lateral ocellus to eye. Eyes in dorsal view distinctly bulging beyond temples; eye in lateral view 3.8–4.2 × longer than temple. Malar space long, 0.55–0.70 × width of clypeus, about 0.65–0.80 × basal width of mandible; malar sulcus deep, distinct. Clypeus relatively tall, narrow, 1.85–2.00 × wider than high, triangular in outline, nearly flat in profile, ventral margin very shallowly concave; surface sparsely punctate; anterior tentorial pits large, round. Mandibles with dorsal tooth longer than ventral tooth, ventral tooth strongly twisted medially. Occipital carina widely separated from hypostomal carina ventrally; sharp and distinctly elevated throughout, extending dorsally distinctly below top of eye in lateral view, strongly reflected medially at dorsal terminus; anterior margin impressed and weakly crenulate, especially dorsally. Hypostomal carina protruding as a short flange beneath mandible when mandible closed. Antenna with 44–46 flagellomeres; first flagellomere 2.50–2.75 × longer than wide, 1.15–1.20 × longer than second, twentieth flagellomere 1.50–1.85 × longer than wide; apical flagellomere with long, spine-like extension at tip. Maxillary palps considerably longer than height of head.
Mesosoma (Figs 21, 22) 1.3–1.4 × longer than high, 1.8–1.9 × longer than wide; 1.3–1.4 × higher than wide. Pronotum dorsally with median pit indistinguishable within transverse, crenulate sulcus, otherwise polished, with two transverse rows of setae; pronotum laterally with transverse sulcus extending ventrally along posterior side of sharp vertical carina, carina distinctly distant from anterior margin, weakening ventrally; posterior margin weakly crenulate from ventral corner nearly to level of mesothoracic spiracle; surface otherwise completely smooth and polished. Propleural flange small but distinct, flat or nearly so, not strongly bent posteroventrally; not separated from remainder of propleuron by a sculptured groove. Notaulus a small, teardrop shaped dimple, not extending to anterior margin of mesoscutum; scattered setae present around notaulus, extending as a discrete row along lateral margin to tegula and as a somewhat irregular row posteriorly, covering at least anterior 0.5 of disc, with a few, scattered setae extending further posteriorly; mesoscutum otherwise as in halidayi. Scutellar sulcus narrow, with 6–7 distinct ridges. Scutellum weakly convex, polished throughout. Metanotum with small median tubercle bearing a low median longitudinal carina. Propodeum coarsely carinate-rugose throughout, with median, bifurcating carina (as in halidayi) present but not as readily discernible due to surrounding sculpture, and with portion anteriorad bifurcation shorter; depression separating propodeum from metapleuron poorly defined relative to surrounding sculpture, distinct boss absent adjacent spiracle. Metapleuron and mesopleuron as in halidayi except band of setae between subtegular ridge and hind coxa broader, usually extending to hind margin, subtegular ridge less prominently buldging anteriorly, nearly flat, and crenulate precoxal sulcus extending over middle 0.60–0.75 of mesopleuron.
Fore wing (Fig. 13) with stigma about as in halidayi except, r nearly equal in length to width of stigma at junction of r; second submarginal cell large, weakly converging distally, 4-sided, m-cu distinctly antefurcal, 2M straight, 2RS reclivous, nearly straight, without medial thickening, r-m completely depigmented and desclerotized; 3RSa 2.3–3.0 × longer than r; r-m and 3RSb essentially as in halidayi; (RS+M)a distinctly sinuate, arising further from parastigma than in halidayi, 1RS variable, 3.5–5.5 × longer than wide, 0.25 × length of 1M; (RS+M)b not obviously thickened, often partly depigmented, distinctly longer than 1CUa; 1M 1.3–1.4 × longer than m-cu, m-cu straight; 3M tubular basally and usually distinctly pigmented at least over about basal 0.5, spectral and depigmented distally; 1cu-a inclivous, separated from 1M by distinctly less than its own length, 1CUa thickened throughout; 1st subdiscal cell closed, parallel-sided, 2CUa inclivous, less than twice length of tubular, nearly vertical 2cu-a; 1-1A weakly bowed towards wing margin, slightly thickened along portion nearest margin, separated from the latter at that point by 2.0 × its width. Hind wing with RS absent or present only as a very short, basal stub; 2M weakly but distinctly pigmented for most of its length; m-cu absent; 2-1A present but very short.
Metasoma (Figs 21, 22) with petiole 0.95–1.10 × longer than apical width, apex 1.9–2.0 × wider than base; dorsal carinae extending over about basal 0.8 of petiole, slightly converging throughout, bordering median elevation posteriorly, outline of dorsal carinae and median elevation tapered posteriorly, not hour-glass shaped, in dorsal view; sculpture and contour otherwise as in halidayi except scupture more evident posteromedially; dorsal and lateral carinae meeting at base above small, round laterope, dorsope absent. T2 distinctly shorter than T3; portion of T2 median tergite on which spiracle resides not clearly delimited from rest of median tergite. Hypopygium weakly sclerotized medially, folded along midline; long, with posterior margin strongly protruding medially, extending to tip of metasoma; densely covered with long, nearly erect setae. Ovipositor protruding distinctly beyond metasoma, 2.0 × longer than mesosoma, upper valve with low but distinct subapical node, the node relatively short, blunt; ovipositor sheath 1.4 × length of mesosoma, with setal pattern as in halidayi.
Color. Antenna, labrum, mesothorax, most of pronotum, at least margins of metanotum, fore and middle trochanters, trochantelli, femora, and tibiae, most of hind tibia, hind tarsomeres 1–4, and basal 0.9 of ovipositor sheath black; apical teeth of mandible, vertex, occiput, and sometimes frons medially, small area ventrad mesopleural sulcus, tegula often, and middle portions of metanotum brown to reddish brown; remainder of head and most of metasoma dorsally yellow; palps, small spot near middle of anterior margin of pronotum laterally, hind coxa, trochanter, and trochantellus, all of metapleuron, propodeum, and petiole, and remainder of metasoma pale yellow to white; propleuron yellow, though often extensively infumate; apical 0.1 of ovipositor sheath usually orange; fore and mid coxae usually dark brown apically, yellow to pale yellow basally; fore and mid tarsomeres dark yellow to yellow brown; posterior face of mid femur often variegated dark brown and yellow; hind femur pale yellow with apical dark spot dorsally, hind tibia dark brown to black, usually with discrete basal/subbasal and median yellow spots dorsally; hind tarsus with fifth tarsomere dark yellow; wings lightly but distinctly infumate throughout, stigma and veins black except most of M+CU usually brown to dark brown.
Male (Fig. 19) as in female except as follows: antenna a little shorter, 5.9–6.0 mm, with 43–45 flagellomeres; eye/temple ratio more variable, in lateral view eye 4.1–4.6 × longer than temple; malar space 0.55–0.60 × width of clypeus; fore wing 3RSa 2.6–2.8 × longer than r; petiole more slender, 1.10–1.25 × longer than apical width, apex 1.65–1.80 × wider than base. Color as in female except T7–8 dark brown to black and propleuron yellow.
