Type
species,
zurqui
sp. nov.
, here designated.
This new genus is introduced to absorb an unusual diallactiine from
Costa Rica
, which has the
Haplusia
type
of wing venation (
Fig. 15D
), but is otherwise completely different from other
Diallactiini
, including
Haplusia
.
Diagnosis.
Loboplusia
is the only genus of Winnertziinae, including
Diallactiini
, whose scutum has a bright membranous window anterior of the scutellum (= prescutellar window, ↓,
Fig. 15C
). Setae on the legs, especially the tarsi, are fringed (
Fig. 15E
), a condition I have not noticed in any other mycophagous cecidomyiids. Male genitalia are remarkable for the gonostylus consisting of two lobes (↓,
Fig. 15A
), and for the gonocoxae whose ventrobasal bridge is extremely short (↓,
Fig. 15A
). The ovipositor of
Loboplusia
is more compact (
Fig. 16A
) than that of any other diallactiine I have seen.
Etymology.
The generic name is composed of
Lobo
-, from the Latin word
lobus
for lobe, with reference to the bilobed gonostyli, and the ending -
plusia
, from
Haplusia
, a genus with which
Loboplusia
shares similar venation. Gender of the name is feminine.
