Myosoma brullei SZÉPLIGETI

(Figs 38–47)

Myosoma brullei Szépligeti, 1906: 587 (1 ♀), type locality: “ Bolivien: Mapiri”, female holotype (designated by J. PAPP in QUICKE 1991 l.c.) in Magyar Természettudományi Múzeum, Budapest; examined. – SHENEFELT 1978: 1707 (literature up to 1906). QUICKE 1991: 184 (type depository).

Designation of the female holotype of Myosoma brullei – (first label, printed) “ Bolivia / Mapiri”; second label is the holotype card, third label is with the inventory number “1243” (2nd and 3rd labels attached by me); fourth label is with the actual name Myosoma brullei given by QUICKE 1989 (label reverse with “teste Papp J. 1991”). – Holotype is in fairly poor condition: (1) pinned by mesosoma (before prescutellar furrow); (2) both flagelli distally deficient; (3) right fore wing (proximal from pterostigma) somewhat deficient; (4) missing: tarsomeres 3–5 of left middle and right hind legs, pair of ovipositor sheaths.

Redescription of the female holotype of Myosoma brullei – Body 8 mm long. Both flagelli deficient distally: right flagellum with 31 and left flagellum with 39 flagellomeres. Scape in outer-lateral view dorsally just longer than ventrally and 1.35 times longer than broad apically; first flagellomere somewhat longer than broad, 2–6(–7)th flagellomeres shortening to transverse, i.e. slightly broader than long. – Head in dorsal view transverse (Figs 38–39), 1.7–1.8 times as broad as long, eye 1.5 times longer than temple, temple moderately rouned, eye slightly protruding. Ocelli jus elliptic, OOL almost three times longer than POL. Eye in lateral view 1.3 times as high as wide, temple beyond eye 0.7 times as wide as eye and narrowing ventrally. Horizontal diameter of oral opening 1.6 times longer than shortest distance between opening and eye. Head polished and with long hairs.

Mesosoma in lateral view 1.7 times as long as high, polished. Notaulix almost indistinct. – Hind femur less thick, 3.8 times as long as broad medially and with long hairs (Fig. 40). Hind basitarsus as long as tarsomeres 2–4 combined. Legs hairy. Claw downcurved with wide and pointed basal lobe (Fig. 41).

Fore wing as long as body. Pterostigma (Fig. 42) 2.8 times as long as wide and isuing r somewhat proximally from its middle, r 0.8 times length of pterostigma. Second submarginal cell long, 3–SR 2.6 times as long as 2–SR; SR1 bent, reaching tip of wing, slightly longer than 3–SR. First discal cell: 1–SR–M 1.6 times longer the 1–M, 1–M and m–cu parallel (Fig. 43). – Hind wing: 1r–m bent (Fig. 45) or straight (Fig. 44).

First tergite (Fig. 46) 2.6 times as long as broad behind, together with further tergites polished. Second tergite 3.3 times as broad behind as long medially, laterally narrowing; third tergite 1.25 times longer than second tergite (Fig. 47). Hypogium pointed, ovipositor sheath long, as long as hind tibia + tarsomeres 1–3 combined (Fig. 47).

Antenna, body and legs black. Mandible dark rusty. Cheek brownish yellow. Tergites 1–2 laterally reddish. Wings brown fumous, distally (beyond pterostigma) subhyaline.

Male and host unknown.

Distribution – Bolivia.

Taxonomic position – Myosoma brullei is nearest to M. errans, for their distinction see key-couplets 12 (13)–13 (12).
