(
Figs 42–52
)
Description
– Female. Head uniformly dark brown to black; pronotum, scutum and scutellum black; mesopleuron, propodeum dark brown, antennae and legs uniformly light brown; wing veins light brown; metasoma reddish brown. Head from above 2.2 times as wide as long (
Fig. 42
), 1.3 times as broad as high and subquadrate in front view, as broad as thorax, gena not broadened behind eye (
Fig. 43
); POL 3.5 times as long as OOL, OOL slightly longer than diameter of lateral ocellus; vertex, frons and gena delicately coriaceous; interocellar area and occiput with very weak, delicate dense transverse striae; lower face and gena with delicate striae irradiating from clypeus to eye and antennal socket (
Fig. 43
); malar space 0.5 times as long as height of eye (
Fig. 43
); lower face, clypeus and malar space with dense uniform white setae, frons with very sparse few white setae. Antenna 13-segmented, flagellomeres slightly broadened to F11, F1 1.6 times as long as pedicel and 1.3 times as long as F2 and nearly equal F3; F11 1.3 times as long as F10 (
Fig. 44
). Mesosoma 1.25–1.3 times as long as high from lateral view (
Fig. 46
). Pronotum with uniform dense pubescence, dorsally delicately coriaceous, with stronger sculpturing laterally, with strong lateral pronotal carina (
Fig. 46
). Scutum from above 1.25 times as broad as long, with weak, interrupted transverse rugae, interspaces between rugae delicately coriaceous; notauli complete, narrow and distinct, slightly broader posteriorly and narrowed down anteriorly; median scutellar line present in form of impression at the main base of scutum; parapsidal lines present, reach to 1/2 of scutum (
Fig. 47
). Mesopleuron with delicate transverse striae reach to the end of mesopleuron in ventral half, while upper half posteriorly smooth and shiny (
Fig. 46
). Scutellum slightly longer than broad, with sparse white setae, dull rugose, scutellar foveae narrow, distinctly delimited from disk of scutellum, separated by a central narrow carina, bottom of foveae smooth (
Fig. 47
). Propodeum finely coriaceous, with uniform short dense white setae laterally, lateral propodeal carinae straight, slightly diverging towards metascutellum, central area smooth, without setae; metascutellum smooth, shining. Fore wing margin ciliate; radial cell open, 3.0 times as long as broad, areolet distinct, small, closed, second abscissa of Rs only slightly curved not reaching wing margin, as well as R
1
(
Fig. 48
). Tarsal claws with basal lobe. Petiole sulcate; metasomal terga 2+3 without minute punctures posteriorly, prominent part of ventral spine of hypopygium short, nearly as long as broad (
Fig. 50
). Length
1.9–2.3 mm
.
Male. Similar to female, except frons, lower face, pronotum, scutum and scutellum with very dense white pubescence; antennae and legs yellow; antenna 15-segmented, F1 curved and slightly expanded apically, F7–F9 broadest flagellomeres, F10 to F13 narrower (
Fig. 45
); fore wing narrower, with longer margin cilia, areolet slightly larger (
Fig. 49
); metasoma in
Fig. 51
.

Holotype

and

and
1 male
paratypes
in the collection of the

Etymology
– The species is named in honour of Dr. Nai-quan Lin, Professor of the Biological
Control Research Institute,
Fujian
Agriculture and Forestry University (Fuzhou,
Fujian
,
China
). Host cynipid galls are unknown
.
Diagnosis
– Closely related to
S. diversus
BELIZIN
, 1968
, however,
S. naiquanlini
differs in the F1 of female antenna only 1.3 times as long as F2, F11 1.3 times as long as F10, subsequent flagellomeres nearly of the same length; the mesopleuron striate, the median scutellar line is very short, in a form of a depression at the main base of the scutum; the central propodeal area is smooth and shiny, without pubescence; the base of terga 2+3 without a line of sparse white setae. In
S. diversus
F1 almost nearly 2.0 times as long as F2, F11 2.0 times as long as F10, subsequent flagellomeres shortening to the end of the antenna; the mesopleuron is shiny and smooth; the scutum with a distinct median scutellar line; the propodeum is uniformly pubescent; the base of terga 2+3 with a line of sparse white setae.
