Name
Blacus latestigma Papp, 2012 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Holotype ♀:
COLOMBIA, Amazonas, PNN Amacayacu San Martin, 150 m, 3°23'S, 70°6'W, Malaise trap, leg. B. Amado. Holotype is in good condition: (1) glued on a card point by the right metapleuron, (2) right femur + tibia in glue, hardely visible, (3) left hind leg on the right side owing to the mounting.
Etymology
The name latestigma refers to the wide pterostigma.
Description
Body 2.5 mm long. Antenna somewhat longer than body and with 25 antennomeres. First flagellomere six times as long as broad apically and 1.5 times as long as second flagellomere, subsequent flagellomeres shortening so that penultimate flagellomere twice as long as broad. Head in dorsal view (Fig. 41) distinctly twice as broad as long, eye almost four times as long as temple, temple receding. Occiput carinate. Ocelli elliptic, OOL twice as long as POL. Malar suture present. Maxillary palp somewhat longer than height of head. Eye in lateral view 1.3 times as high as wide. Head polished.
Mesosoma in lateral view 1.4 times as long as high. Notauli distinct, smooth. Precoxal suture short with weak crenulae. Lateral carina of scutellum missing. Propodeum rugose (like Fig. 101 in van Achterberg 1976[1]: 64). Hind femur five times as long as broad distally (Fig. 11). Claw simple, basal lobe distinct (Fig. 43).
Fore wing almost as long as body. Pterostigma wide (Fig. 44), 2.6 times as long as wide, r issuing somewhat distal to middle, r 0.8 times as long as width of pterostigma. 2–SR nearly 1.6 times as long as r, 3–SR + SR1 slightly bent and reaching tip of wing, 2–M short. First subdiscal cell open distally (Fig. 45, see arrow). Hind wing: cu–a slightly proximal to middle of vein M+CU + 1–M (Fig. 46, see arrow).
First tergite long and hardly broadening posteriorly (Fig. 47), 2.2 times as long as broad posteriorly, pair of keels distinct, finely striate. Second tergite almost 1.9 times as broad posteriorly as long, anteriorly strio-rugulose. Further tergites polished. Hypopygium fairly large, ovipositor sheath downcurved, somewhat longer than hind tibia.
Scape, pedicel and flagellomeres 1–2 straw yellow, rest of flagellum brown. Head brownish yellow, occiput brown, mouthparts whitish. Mesosoma blackish brown, tegula brown. Legs yellow, coxae and trochanters straw yellow. First tergite blackish brown, further tergites brown, anterior sternites whitish. Wings hyaline, pterostigma brown, parastigma whitish, veins opaque brown.
Male and host
unknown.
Distribution
Colombia.
Diagnosis
The new species, Blacus (Tarpheion) latestigma, runs to Blacus (Tarpheion) erugatus van Achterberg with the help of van Achterberg’s keys (1976: 186, 1988: 140–141); the two species differ from each other by a few features.
