Myosoma hirtipes BRULLÉ

( Figs 66–73 )

Myosoma hirtipes BRULLÉ, 1846: 451 ♀ (1 ♀), type locality: “l’Amérique méridionale”, female holotype (designated by VAN ACHTERBERG 1978, in litt.), in Muséum National d’Histoire Naturelle, Paris; examined. – VIERECK 1914: 97 (type species of Myosoma ). SHENEFELT 1978: 1708 (literature up to 1914).

Designation of the female holotype of Myosoma hirtipes – ( First label, printed) “Museum Paris / EY000000166”; (second label) “Museum Paris” (printed) “Cayame / Leprieur 302 1899” (handwriting, “ Cayame ” = Cayambe in Ecuador); (third label, handwriting) “ Myosoma / hirtipes Br. ”; fourth label is the holotype card attached by vAN ACHTERBERG in 1978. – The holotype is in poor condition: (1) pinned by mesosoma; (2) missing: both flagelli, fore right wing and metasoma; (3) left fore wing torned medially.

Redescription of Myosoma hirtipes – Body? 8 mm long. Scape broad, in outer-lateral view 1.25 times as long dorsally as broad apically, dorsally longer than ventrally ( Fig. 66 ). – Head in dorsal view less transverse ( Fig. 67 ), 1.6 times as broad as long, eye 1.7 times longer than temple, temple less rounded ( Fig. 67 ). Ocelli less large, elliptic, OOL twice longer than POL. Eye in lateral view 1.4 times as high as wide, temple beyond eye 0.7 times as wide as eye and narrowing ventrally ( Fig. 68 , see arrows). Horizontal diameter of oral opening twice longer than shortest distance between opening and eye. Head polished, face just uneven, shiny.

Mesosoma in lateral view 1.8 times as long as high, polished. Notaulix faintly distinct anteriorly, smooth. – Hind femur 3.5 times as long as broad medially and together with hind tibia with long hairs ( Fig. 69 ). Hind basitarsus as long as tarsomeres 2–3 combined. Claw downcurved and its basal lobe wide and pointed as in Fig. 70 .

Fore wing twice longer than head and mesosoma combined. Pterostigma ( Fig. 71 ) 3.3 times as long as wide and issuing r somewhat proximally from its middle, r 0.8 times as long as width of pterostigma. Second submarginal cell long, 3–SR 2.1 times as long as 2–SR; SR1 bent, reaching tip of wing and 1.25 times longer than 3–SR. First discal cell: 1–SR–M twice longer than 1–M, 1–M and m–cu almost parallel ( Fig. 72 ). – Hind wing: 1r–m curved ( Fig. 73 ).

Metasoma missing.

Scape, head, mesosoma and legs black. Metasoma entirely reddish. Long hairs of hind femur and tibia also black. Inner side of hind coxa, femur and tibia rusty. Fore wing: proximal half subhyaline, distal half brown fumous (medially less fumous).

Distribution – Ecuador.

Taxonomic position – Myosoma hirtipes is nearest to M. fuscipenne , distinction of the two species is presented in the key-couplets 15 (16)–16 (15).
