Dorothee
gen. nov.
(
Figs 1–18
)
Type
species.
Dorothee panguanensis
n. sp.
, by present designation.
Diagnosis
. This new genus is similar to
Aprix
Townes, 1961
and
Chamula
in having lower tooth of mandible as long as upper tooth (
Fig. 11
), frons with a single median horn (
Figs 11 & 12
), apical margin of clypeus without a median pair of tubercles (
Fig. 11
) and frontal horn without a groove along its upper edge (
Fig. 12
). However, it differs from
Chamula
in not having a distinct epomia (
Figs 2
&
9
) and from
Aprix
(from
Australia
) in lacking a dorsal lobe in the lower valve of ovipositor (
Fig. 17
).
Dorothee
also differs from
Trachyglutus
(from
Brazil
) in having a horn in the frons (
Figs 11 & 12
).

, 1. Habitus (lateral view), 2. Mesosoma (lateral view).
Female
. Fore wing
14.4 mm
. Hind wing
10.2 mm
. Body rather slender.
Head
. Frons with a moderate median conical horn (
Figs 11 & 12
); clypeus wide, convex, its apical margin truncate forming a narrow flange (
Fig. 11
); malar space 0.85 × as long as the base of mandible (
Figs 9 & 11
); lower part of gena forming a distinct flange, ventrally bordered by the hypostomal carina (
Fig. 9
); lower tooth of the mandible about the same length as upper tooth (
Fig. 11
); eye laterally 3.1 × as long as temple (
Fig. 9
).
Mesosoma
. Lower corner of pronotum with a sharp end (
Figs 2
&
9
); epomia almost completely absent (ventrally vestigial) (
Figs 2
&
9
); epicnemium smooth; notauli distinct, reaching center of mesoscutum (
Figs 4
&
9
); propodeum convex, with anterior transverse carina complete and strong, posterior transverse carina only represented by sublateral teeth (
Figs 2
&
4
); transverse furrow at base of propodeum moderately broad (
Fig. 2
); fore wing with areolet about 1.7 × as wide as high, receiving 2m-cu distad of center, basad of 3rs-m, which is only pigmented in its basal 0.40 and in its apex (
Figs 5 & 6
); fore wing with 1cu-a basad of M&RS by about 0.13 × its length (
Fig. 6
).

Metasoma
. Petiole of 1
st
abdominal segment subcylindrical, mostly rounded, the juncture of its sternite and tergite not marked by a distinct suture (
Figs 14 & 15
); base of petiole with a lateral triangular tooth (
Fig. 16
); apex of first sternite opposite to spiracle (
Fig. 14
); hind tibia 0.76 × as long as ovipositor (
Fig. 13
); tip of lower valve of ovipositor without lobe (
Fig. 17
).

Etymology
. The genus name is dedicated to the German geographer
Dorothee Uchtmann
, with my respect and admiration for her undergraduate work on deforestation in the Colombian Amazon and wishing her all the best in her Master’s studies in sustainable development.
Biology
. Unknown.
