Designation of the female
holotype
of
Myosoma fasciatum
– (First label, printed) “Museum Paris / EY0000001663”; (second label) “Museum Paris” (printed) “
Surinam
/ Leschenault” (handwriting); (third label, handwriting) “
Myosoma fasciata Br
.”; fourth label is the
holotype
card attached by me. –
Holotype
is in poor condition: (1) ventral side of body, legs and back side of left hind wing dirty; (2) missing: head, tarsomeres 3–5 of right fore leg, tarsomeres 2–5 of right hind leg, tarsus of left hind leg; (3) left hind wing somewhat creased longitudinlly. – Remark: In his original description BRULLÉ (l.c.) indicated: “La tęte manque.”
Designation of the female “Type” (=
Holotype
) of
Ipobracon pennipes
MYERS.
–(First round label with red frame) “Type / H.T.”; second label is with the inventory number “3.c.418”; (third label) “D 115.53” (handwriting) / “Brit.

Berbice
” (printed) / “Myers 12. IV. 29” (handwriting); (fourth label, handwriting) “ex / Dietraea sp.”; (fifth label, handwriting) “
Ipobracon
/ pennipes / Myers type”; sixth label is the presentation card and seventh label is with the actual name
Myosomatoides fasciatus
(BRULLÉ)
(det. J. Papp 2009). – “Type” is in fairly good condition: (1) pinned by the mesosoma, (2) missing: both flagelli and tarsus of right middle leg.

Myosomatoides fasciatus
(BRULLÉ)
,
comb. n.
, female holotype: 94 = hind femur and tibia with hairs, 95 = distal part of right fore wing, 96 = first discal cell of right fore wing, 97 = tergites 1–3
Redescription of the female
holotype
of
Myosoma fasciatum
– Body, i.e. meso- and metasoma (head missing)
5 mm
long. Mesosoma in lateral view 1.5 times as long as high, polished. Notaulix indistinct. Hind femur 2.5 times as long as broad medially, together with tibia with long hairs, femur and tibia laterally flattened (
Fig. 94
;
Fig.
3
in
Quicke 1994: 229
).
Fore wing longer than meso- and metasoma combined. Pterostigma (
Fig. 95
) 4.7 times as long as wide and issuing
r
somewhat distally from its middle,
r
shorter than width of pterostigma. Second submarginal cell long,
3–SR
2.1 times as long as
2–SR
;
SR1
1.2 times longer than
3–SR
, straight and reaching tip of wing. First discal cell long and narrow,
1–SR–M
1.9 times as long as
1–M
(
Fig. 96
).
First tergite (
Fig. 97
) 1.4 times as long as broad behind, broadening posteriorly, together with further tergites polished. Second tergite transverse, 2.4 times as broad behind as long laterally, laterally not narrowing, its medio-longitudinal ridge extending to fore half of tergite. Suture between tergites 2–3 bisinuate (
Fig. 97
). Hypopygium pointed, ovipositor sheath as long as hind tibia and slightly widening posteriorly.
Mesosoma and tergites 1–2 testaceous, tergites 3–5 testaceous with wide blackish band behind, further tergites blackish. Legs also blackish. Wings evenly brown fumous, pterostigma and veins brown.
Complementary description of the head – The female “Type” of
Ipobracon pennipes
is conspecific with the female
holotype
of
M. fasciatus
. Head of the latter type is missing whereas head of the type of
pennipes
is present; subsequently its description is presented: Body
6 mm
long. Scape in outer-lateral view as in
Fig. 84
. Head in dorsal view transverse (cf.
Fig. 85
), 1.7 times as broad as long, eye 1.8 times longer than temple, temple rounded. Ocelli middle-sized, elliptic, OOL twice longer than POL. Eye in lateral view almost 1.5 times as high as wide and 1.5 times wider than temple, temple beyond eye evenly broad. Horizontal diameter of oral opening as long as shortest distance between opening and eye. Head polished, face laterally finely-densely subgranulose, black. Cheek faintly reddish, palpi brown.
Distribution –
Surinam
(
M. fasciatus
);
Argentina
,
Brazil
,
Colombia
,
Ecuador
, Guayana,
Paraguay
(
M. myersi
).
Taxonomic position –
QUICKE (1994)
assigned the species
Myosoma pennipes
WESTWOOD
to the genus
Myosomatoides
QUICKE, 1994
. In his short key the only specific distinction between
M. fasciatus
(BRULLÉ)
(=
M. myersi
) and
M. pennipes
(WESTWOOD)
is the colour pattern of the fore wing: uniformly brown fumous vs hyaline and only the apical third brown fumous, respectively. The short original description of
Myosoma pennipes
by
WESTWOOD (1882)
does not allow for further comments on the characteristics of this species.
