Aclastus mantaricus sp. nov.
( Figs 2 View FIGURE 2 A–C, 3A–B, 4A–F, 5A–F)
Diagnosis: Winged females of Aclastus mantaricus sp. nov. can be distinguished from all other females of New World and European species by the combination of the following characters: metasomal tergites hairless dorsally ( Figs 5 View FIGURE 5 E–F); malar space about 2.2–3.2 times the basal width of mandible and 0.8–0.9 times the width of clypeus ( Fig. 2 View FIGURE 2 A); eyes at most 1.5 times the length of gena; antenna with 17–18 flagellomeres, first flagellomere 4.3–5.0 times as long as wide, length from third to fifth flagellomeres 7.0 times its maximum width ( Fig. 2 View FIGURE 2 B); fore wing with abscissa of Cu 1 between 1 m-cu and Cu 1a shorter than Cu 1b; vein 2 m-cu present ( Fig. 5 View FIGURE 5 A); postpetiole 1.0– 1.1 times as long as wide posteriorly; ovipositor relatively slender, nodus indistinct ( Fig. 2 View FIGURE 2 C), ovipositor sheaths 0.9–1.3 times as long as first tergite; legs entirely light brown.
Brachypterous females can be distinguished from A. glabriventris Horstmann by the combination of the following characters: malar space 1.7–2.5 times as wide as basal width of mandible; antenna with 18 flagellomeres, length from third to fifth flagellomeres 7.5 times its maximum width, and from A. nigritus (Ashmead) by having all coxae orange (black in A. nigritus ).
Description. Winged female: Body length (without ovipositor) 2.6 mm ( Fig. 3 View FIGURE 3 A). Head 0.3 mm long and 0.6 mm wide (from above). Mesosoma 0.4 mm long, 0.4 mm wide (mesoscutum without scutellum). Fore wing 2.5 mm. First tergite 0.4 mm long. Ovipositor sheaths 0.5 mm.
Head ( Figs 2 View FIGURE 2 A–B, 4A). Transverse, 1.9–2.0 times as wide as long, barely constricted behind eyes, rounded ( Fig. 4 View FIGURE 4 A). Gena 0.3–0.4 times as long as eye (viewed from above in a right angle). Frons barely convex, slightly flat just behind antennal sockets. Vertex, face and frons finely punctate (setiferous punctures) on a smooth and shiny background, denser on face, hairs white. Malar space long, 2.2–3.2 times as wide as basal width of mandible ( Fig. 2 View FIGURE 2 A). Antenna with 17–18 flagellomeres; first flagellomere 4.3–5.0 times as long as wide, second one 3.3–3.9 times, length from third to fifth flagellomeres 7.0 times its maximum width ( Fig. 2 View FIGURE 2 B). Genal carina joining hypostomal carina far behind base of mandible, at a distance slightly greater than basal width of mandible. Hind ocelli separated from eye by 1.6–1.9 times their diameter. Space between hind ocelli 1.3–1.5 times as long as their diameter. Occipital carina complete, situated far from ocelli ( Fig. 4 View FIGURE 4 A).
Mesosoma ( Figs 4 View FIGURE 4 A, C, E, 5A). Pronotum smooth and polished, only a few setiferous punctures in its upper hind corner. Epomia distinct, short. Mesoscutum as wide as long, nearly round, and strongly convex; finely punctate on a shiny background. Notaulus present, ending at approximately half length of mesoscutum. Scutoscutellar groove wide, smooth, without longitudinal wrinkles. Scutellum convex, same sculpture as mesoscutum, not delimited by a strong carina ( Fig. 4 View FIGURE 4 A). Mesopleuron mostly smooth and shiny, finely punctate on upper edge and convex area just below sternaulus, which is clearly distinct and reaches, at least, half width of mesopleuron. Epicnemial carina distinct, reaching propleura on its upper third, upper part slightly diverging from it. Mesopleural fovea deep, mesopleural suture absent ( Fig. 4 View FIGURE 4 C). Metapleuron smooth and shiny, with sparse and fine setiferous punctures, with irregular wrinkles in its lower part, beside hind coxa; metapleural fovea absent; propodeum with transverse and longitudinal carinae, sometimes longitudinal carinae are faintly developed, area superomedia transverse; mostly smooth and shiny, with some granulate areas, specially adjacent to carinae; propodeal spiracle small, rounded, not touching dorsal nor pleural carinae, but connected to latter by a short carina ( Fig. 4 View FIGURE 4 E). Hind femur 5.7–6.5 times as long as high. Hind tibia 8.3–8.6 times longer than wide; tibial spurs nearly same length.
Wings ( Fig. 5 View FIGURE 5 A). Ramulus absent. Vein 3 rs-m absent, thus areolet open. Vein 2 m-cu slightly inclivous, reaching areolet at a distance from 2 rs-m approximately equal to its length, with a single bulla occupying approximately its upper half, lower half not completely pigmented. M absent beyond areolet. Cu-a interstitial to Rs & M. Cu 1a reaching Cu 1b slightly above its middle, Cu 1b barely reclivous, distinctly angular, Cu 1a not complete until end of wing. Cu-a in hind wing not intercepted, Cu 1 absent; M + Cu strongly curved in its distal half.
Metasoma ( Figs 2 View FIGURE 2 C, 5C, E). First metasomal tergite 1.8–2.2 times as long as wide. Lateral longitudinal carinae absent or indistinct; spiracle situated at apical 0.4 of first tergite ( Fig. 5 View FIGURE 5 C). Tergites 2–8 transverse, second one 0.7–0.9 times as long as wide. First tergite strongly granulate and faintly aciculate; other tergites smooth and polished; tergites 2–5 with few sparse hairs, 6–7 more or less hairy ( Fig. 5 View FIGURE 5 E). Ovipositor slightly and uniformly upcurved, nodus indistinct, without teeth, apex gradually pointed ( Fig. 2 View FIGURE 2 C). Ovipositor sheaths 0.9–1.3 times as long as first tergite.
Colouration ( Fig. 3 View FIGURE 3 A). Body dark brown to black. Antennae brownish. Legs and mandibles light brown. Anterior part of tergite II and basal part of tergite III light brown, sometimes tergite II entirely light brown.
Brachypterous female: Body length (without ovipositor) 2.4 mm ( Fig. 3 View FIGURE 3 B). Head 0.3 mm long and 0.5 mm wide (from above). Mesosoma 0.3 mm long, 0.3 mm wide (mesoscutum without scutellum). Fore wing 1.2 mm. First tergite 0.4 mm long. Ovipositor sheath 0.5 mm.
Head ( Fig. 4 View FIGURE 4 B). Transverse, 1.6–1.8 times as wide as long ( Fig. 4 View FIGURE 4 B). Malar space 1.7–2.5 times as wide as basal width of mandible. Clypeus only slightly convex. Antenna with 18 flagellomeres; first flagellomere 5.3–6.2 times as long as wide, second one 3.5–4.5 times; length from third to fifth flagellomere 7.5 times its maximum width. Hind ocelli separated from eye by 1.7–2.2 times their diameter. Space between hind ocelli 1.7–2.4 times as long as their diameter ( Fig. 4 View FIGURE 4 B).
Mesosoma ( Figs 4 View FIGURE 4 B, D, F, 5B). Pronotum smooth and polished, only a few setiferous punctures in its upper hind corner ( Fig. 4 View FIGURE 4 D). Epomia distinct, short. Mesoscutum very sparsely and finely punctate on a shiny background ( Fig. 4 View FIGURE 4 B). Propodeum mostly smooth and shiny, with some granulate areas adjacent to the carinae, more extensive than in winged female; area superomedia slightly longitudinal ( Fig. 4 View FIGURE 4 F). Hind femur 5.9–7.1 times as long as high. Hind tibia 8.0–9.0 times longer than wide.
Metasoma ( Figs 5 View FIGURE 5 D, F). First metasomal tergite ( Fig. 5 View FIGURE 5 D) 1.8–1.9 times as long as wide. Tergites 2–8 transverse, second one 0.6–0.7 times as long as wide ( Fig. 5 View FIGURE 5 F). Ovipositor sheaths 1.1–1.2 times as long as first tergite.
