Saphonecrus chaodongzhui sp. n.
( Figs 34–41 View Figs 34–41 )
Description – Female. Vertex, interocellar area, occiput and central rounded area on frons black; genae, narrow stripes around compound eyes, lower face and clypeus brown, except two blackish brown lateral spots on lower face; mandibles yellow with dark brown tips, labial and maxillar palpi yellow; antennae and legs uniformly light brown, except darker hind coxae; wing veins distinct, brown; mesosoma black, except light brown to yellow tegula; petiole black, metasoma reddish brown, to dark brown dorsally, uniformly lighter till ventral part. Head from above 1.9–2.0 times as broad as long ( Fig. 34 View Figs 34–41 ), 1.2 times as broad as high and subquadrate in front view, as broad as thorax, gena not broadened behind eye ( Fig. 35 View Figs 34–41 ); POL nearly equal OOL, OOL 1.8–2.0 times as long as diameter of lateral ocellus. Vertex, interocellar area, occiput, frons and gena delicately coriaceous; two very weak frontal carinae delimited a dark very slightly impressed central area between antennal sockets and ocelli, with very weak incomplete central vertical carinae ( Figs 34–35 View Figs 34–41 ); lower face and gena with delicate striae irradiating from clypeus to compound eye and antennal socket ( Fig. 35 View Figs 34–41 ); malar space 0.65–0.7 times as long as height of eye ( Fig. 35 View Figs 34–41 ). Antenna 14-segmented, flagellomeres slightly broadened to F12, F1 1.6 times as long as pedicel and 1.8 times as long as F2, F12 1.7 times as long as F11, F2-F5 shortest flagellomeres ( Fig. 36 View Figs 34–41 ). Mesosoma 1.25–1.3 times as long as high from lateral view ( Fig. 37 View Figs 34–41 ). Pronotum with uniform dense pubescence, delicately coriaceous dorsally, with stronger sculpturing laterally, with weak lateral striae, laterally rounded, without lateral pronotal carina. Scutum subquadrate from above, nearly as long as broad, with weak, interrupted transverse
Figs 31–33. Synergus pallicornis sp. n.: 31 = antenna, F1–F2, female, 32 = antenna, F1–F2, male, 33 = gaster, lateral view, female rugae, interspaces between rugae delicately coriaceous; notauli complete, narrow and distinct, slightly broader posteriorly and narrowed down anteriorly; median scutellar line absent or in two paratype females only very indistinctly indicated at main base; parapsidal lines present reaching to ¾ of scutum ( Fig. 38 View Figs 34–41 ). Mesopleuron with delicate transverse striae ( Fig. 37 View Figs 34–41 ). Scutellum slightly longer than broad, dull rugose, scutellar foveae indistinctly delimited from disk of scutellum, in a form of fore wing, 40 = hind leg, tarsal claw, 41 = metasoma, lateral view male depressions with same sculpture as the disk, separated by elevated central portion ( Fig. 38 View Figs 34–41 ). Propodeum uniformly delicately coriaceous, with uniform short dense white setae, lateral propodeal carinae straight, parallel, central area delicately coriaceous; metascutellum smooth, shining. Fore wing margin ciliate; radial cell opened, 3.0 times as long as broad, areolet distinct, closed, second abscissa of Rs only slightly curved, not reaching wing margin, as well as R 1; R 1 +Sc interrupted before reaching R 1 ( Fig. 39 View Figs 34–41 ). Tarsal claws with basal lobe ( Fig. 40 View Figs 34–41 ). Petiole sulcate; metasomal terga 2+3 with posterior very minute punctures, limited to small apical dorsal patch; hypopygium with very minute dense punctures, ventral ridge with short white setae, prominent part of ventral spine of hypopygium short, 2.0 times as long as broad ( Fig. 41 View Figs 34–41 ). Length 1.9–2.1 mm.
Male unknown.
Type material – Holotype female: both labels in Chinese language “ Yunnan, Diqing, Xiaozhongdian, 3200M, 1984.07.31 ”, “84.7.31, coll. Changfang Li ”, and a red label in English language “ HOLOTYPE. Female. Saphonecrus chaodongzhui Melika, Ács & Bechtold , desig. G. Melika 2003”. Two paratype females with the same labels as the holotype . Holotype female in the Institute of Zoology of Chinese Academy of Sciences, Beijing, China and 2 female paratypes in the collection of the Systematic Parasitoid Laboratory, Kőszeg, Hungary .
Etymology – The species is named in honour of Dr. Chaodong Zhu, Associate Professor of the
Institute of Zoology, Chinese Academy of Sciences (Beijing, China).
Host cynipid galls are unknown.
Diagnosis – Closely resembles the Western Palaearctic Saphonecrus connatus (HARTIG, 1840): the lateral pronotal carina is absent, the pronotum is rounded in dorsal view; F1 of the antenna less than 2.0 times as long as the pedicel, and the radial cell is 2.5–3.0 times as long as broad. However, in S. chaodongzhui the head and metasoma are brown or reddish brown, the frons with two weak frontal carinae, delimited an impressed central area, notauli are distinct, deep and complete, the disk of the scutellum is dull rugose; the propodeum with dense white setae; the metasoma with an apical patch of minute punctures, while in S. connatus the entire body is black, the frons without central impression and frontal carinae; notauli are absent or very indistinctly traceable at the main posterior part of the scutum; the disk of the scutellum is delicately coriaceous; the propodeum is smooth, shiny, without setae; the metasoma without apical patch of minute punctures. Saphonecrus chaodongzhui also closely related to S. sinicus BELIZIN, 1968 , described from China, Sechuan, but differs in the presence of a central impressed area on the frons, notauli are distinct, deep, parapsidal lines present, anterior parallel lines are absent, the scutellum is narrower than the scutum; tergite 3 without a line of short white setae at the base, while in S. sinicus the frons is uniformly delicately coriaceous, without traces of frontal carinae and impressed central area, notauli are very narrow, parapsidal lines are absent, anterior parallel lines are present, and the base of scutellum as broad as the scutum; tergite 3 with a line of short white setae.
Distribution – China, Yunnan, Diqing, Xiaozhongdian.
