Comments.
This is a well-known species, redescribed and illustrated by Rosen & Alon (1983). It was described from
Australia
, and later recorded from
Malaysia
,
Samoa
,
Israel
, and
India
(Andaman &
Nicobar Islands
; Hayat 2006). It is here recorded for the first time from Karnataka State.

Type
species
Semen politum
Hoffer, 1957
, by monotypy and original designation.
A diagnosis of
Globulencyrtus
is given below based on the original description by Hoffer (1975), the description of an Australian species by Simutnik & Trjapitzin (2008) and the two Indian specimens.
Female.
Body convex, short, compact. Head sublenticular; occipital margin sharp; frontovertex broad, at least 0.4× head width; ocelli small and arranged in an obtuse-angled triangle; antennal torulus in line with or slightly below lower margin of eye, and separated from mouth margin by at least 2× torulus height. Mandible with two teeth and a dorsal truncation. Antennal formula, 1163; scape cylindrical and elongate; dimensions of funicle segments variable, slightly broader than long to longer than broad; clava 3-segmented and shorter than funicle.
Mesosoma. Pronotum and at least anterior part of mesoscutum hidden by posterior part of head; pronotum shorter than mesoscutum; mesoscutum with posterior margin truncate (straight); scutellum with both posterior and anterior margins truncate; axilla small and elongated; tegula large; metanotum and propodeum not visible in cardmounted specimens, but in a specimen dissected and mounted on slide, metanotum appears as a very narrow strip and propodeum also as a narrow strip except laterally expanded with spiracles visible (
Fig. 25
). Fore wing rudiments sclerotized or membranous, subtriangular, posteriorly reaching to about apex of scutellum and the two wing rudiments widely separated posteriorly; hind wing not detected. Legs with fore and hind femora robust; tarsal formula, 5–5–5.
Metasoma. TI of gaster 3–4× as broad as long and longer than TII–TVI individually; TII–TVI narrow strips; median length of TVII slightly shorter to distinctly longer than length of TI; hypopygium extending nearly to apex of gaster (
Fig. 19
); ovipositor with third vulvulae free (
Fig. 27
).
Male
.
Unknown.
Hosts.
Coineau & Davis (1999, not seen, but noted from Simutnik & Trjapitzin 2008) recorded
G. politus
(Hoffer)
as a parasitoid of the predatory mite,
Microcaeculus steineri delamarei
Coineau
(Acarina:
Caeculidae
). Hosts are unknown for the
type
material of
G. politus
,
G. dahmsi
Simutnik & Trjapitzin
, and the Indian specimens.
Distribution.
The
type
species is known from the Palaearctic (
France
,
Mongolia
,
Slovakia
), and is recorded here for the first time from
India
. A second species,
G. dahmsi
, was described from
Australia
(Simutnik & Trjapitzin 2008).
Comments.
Globulencyrtus
is similar to
Semen
Hoffer
(1954,
type
species
S. apterum
Hoffer
) but differs in the following characters: head posteriorly overlapping at least the pronotum and anterior part of mesoscutum; axilla narrow, elongate, small sclerite on each side of scutellum; apex of scutellum truncate; tegula large, about as long as anterior margin of the fore wing; fore wing small, the two wings widely separated posteriorly. In
Semenhead
posteriorly overlapping only pronotum; axilla small but normal, triangular; tegula small; fore wing posteriorly broad, with right wing overlapping left wing posteriorly. The genera
Globulencyrtus
and
Semen
belong to the tribe Discodini Hoffer (1954; see also Noyes 2010).
