pronotal carina distinct, reaching pronotal
crest dorsomedially. Lateral surface of pronotum
foveate-reticulate and punctate. Dorsal
pronotal area glabrate, present to middle
of posterior margin of pronotum. Mesoscutum
strongly arched dorsally and foveatereticulate.
Scutellar sulcus divided by a median
longitudinal carina. Mesoscutellum foveate-reticulate;
posterior margin with a broad
emargination in dorsal view; lateral dorsal
process distinct. Axillar area without distinct
pubescence. Mesopleural triangle pubescent,
well defined ventrally by smoothly curved
carina. Median mesopleural impression percurrent,
transversely costate; upper mesopleuron
glabrous except finely punctate
anteriorly; lower mesopleuron glabrous,
conspicuously depressed along ventral
margin, and conspicuously pubescent ventrally.
Metepisternum areolate-reticulate in
upper part and conspicuously pubescent
ventrally. Lateral propodeal carina abruptly
curved medially; median propodeal area
areolate-reticulate; median longitudinal
carina percurrent, crossed by submedian
transverse carina. Rs+M of forewing arising
from middle of basal vein. Marginal cell
2.4 times as long as wide and slightly longer
than submarginal cell. Bulla on Sc+R 1
absent.
Petiole 1.4 times as long as wide in lateral
view. Relative length of T3–8: 1.7:1.0:1.1:
1.0:0.8:1.1; T3–4 glabrous; T5–8 densely
punctate; T6–8 also with sparse, larger
puncture with pubescence. Apical teeth of
metatibia long, slender, and pointed apically.
1mt/2–5mt 5 0.65.
FEMALE: Unknown.
Paramblynotus hainanensis is similar to P.
annulicornis and the other species of the
annulicornis species complex discussed below.
It differs from the latter by its entirely brown
to dark brown body, antenna with a submedial
pale ring, and mesoscutellum with
a broad posterior emargination.
TYPE MATERIAL: HOLOTYPE: =, China:
Hainan, Tien Fong Mt. (as reads in the label,
but most probably Tie Feng Mt.), 1983-V-16,
Boucek coll. (USNM). PARATYPE: 1=, same
data (USNM).
DISTRIBUTION: Hainan, China.
ETYMOLOGY: This species is named after
the type locality.
Paramblynotus annulicornis Cameron, 1910
figures 64–71
Paramblynotus annulicornis Cameron (1910: 132,
=; Borneo; BMNH HT=, no. 7.11).
FEMALE:
Length 4.0–8.0 mm. Body usually
entirely light to dark brown; metasoma
of some males nearly black. Antenna 13-
segmented and parti-colored with a medial
pale ring including distal half of F6, F7,
usually F8, and occasionally F9; scape,
pedicel, and F1–5 dark brown; flagellomeres
beyond the pale ring black. Forewing
with a deep ferruginous macula covering
marginal cell and the basal part of submarginal
cell.
MALE: Length 4.0–5.0 mm. Antenna
14-segmented. Pale ring of antenna usually
less extensive than in female, only involves
F6–7.
Paramblynotus annulicornis, barbarae,
stigi, shimenensis, glaberus, yuani, weiae,
eriki, asae, filippae, ebbae, and axelli form
a monophyletic clade referred here as the
annulicornis species complex. All of these
species are distributed in the tropical southern
Pacific islands, except P. shimenensis
from the subtropical central south of China
(also see earlier biogeographical discussion).
The species complex is easily distinguished
from other species of the genus in that the
antenna has a submedial pale ring including
F5/6–6/10, contrasting to the rest of flagellum;
body mostly yellow and sometimes dark
brown; and forewing with a deep ferruginous
macula covering marginal cell and basal third
of submarginal cell.
Considering the relatively small amount of
effective distinguishing features among the
species and variations across species of the
species complex, it is likely that some of the
species names described herein may eventually
turn out to be synonymies of the others.
Nonetheless, we think that it is advantageous
to describe them as we perceive and provide
a platform for future taxonomic revision
when a greater number of specimens of the
complex become available.
