Zagrammosoma dulanense Cao & Zhu, 2014

( Figs 5–10)

Zagrammosoma dulanense Cao & Zhu in Cao, LaSalle & Zhu, 2014: 48.

Diagnosis (from Cao & Zhu 2014): “Antenna with fuscate setae on flagellum … Mesosoma yellow with dark pattern and marking except pronotum and lateral lobes of mesoscutum pale yellow. A narrow median black stripe extends along the whole length of the mesosoma excluding the neck. Forewing with large bare area and fuscate parastigma and stigma vein … Stigma long and slightly curved. …black marking pattern on gastral tergites, on which there are three black spots on Gt6 and Gt7 respectively in female and marking on Gt7 are reduced into one median black spot in male”.

Extended diagnosis (based on Israel material): Antenna: F1 1.0–1.1× as long as broad ( Fig. 8), and as long as F2, clava 1.5–1.6× as long as broad. Pronotum pale yellow or whitish with two narrow lateral dark stripes ( Figs 8, 10). Forewing 2.2× as long as broad. Triangular area between PMV and STV bare. SMV with 5–6 setae ( Fig. 5). STV 1.85–1.90× as long as PMV. Size: female 2.2–2.4 mm, male 1.8–2.0 mm.

Description: Female. Body length 2.2–2.4 mm.

Color. Face whitish from frons, vertex yellow ( Figs 7, 8). Occipital foramen with two pairs of dark stripes diverging from occipital foramen ( Figs 6, 9). Pronotum whitish. Propodeum with a black stripe on median line in female ( Figs 5, 6).

Head: POL 1.6× as OOL.Antenna ( Figs 7, 8): scape 4.2× as long as broad; pedicel 1.1× as long as broad; F1 and F2 as long as broad, F1 1.2× as long as F2; clava 3-segmented and 1.7× as long as broad.

Mesosoma ( Figs 5, 6) 1.8× as long as broad. Pronotum 2.7× as broad as long. Mesoscutum 1.2× as broad as long. Scutellum 1.2× as broad as long. Dorsellum as long as propodeum medially. Propodeum 7.5× as broad as long; callus with 2 setae. Forewing 1.95× as long as broad. SMV with 5–6 setae. SMV:MV:PMV:STV 50:41:14:26. Triangular area between PMV and STV bare, or with single seta. MV with 13 setae. Admarginal setae absent. Speculum large and open.

Gaster ( Fig. 5) 1.8× as long as broad, 1.2× as long as thorax, smooth. Sheaths of ovipositor slightly extending from gaster.

Male. Body length 1.8–2.0 mm.

Color ( Figs 9, 10) same as in female except three black triangular spots on Gt6 ( Fig. 9). Antenna ( Fig. 10): scape 4.2× as long as broad; pedicel 1.13× as long as broad; F1 1.06× as long as broad and F2 transverse (1.2× as broad as long), F1 1.13× as long as F2; clava 2.0× as long as broad.

Material examined (all SMNHTAU): Israel: 2♀ Hefer Valley , 32°22'48.7"N 34°55'58.4"E, 17.vii.2013, suction from herbaceous vegetation in a pomegranate orchard, M. Kishinevsky ; 2♂ same data but 31.vii.2013, M. Kishinevsky ; 2♀ Givat Haim [32°23'30"N 34°55'51"E], 17.vii.2013, suction from herbaceous vegetation in a pomegranate orchard, M. Kishinevsky .

Distribution: China (Cao et al. 2014), Israel (new record for the country; Fig. 19-2).

Host: Micrurapteryx sophorivora Kusnetsov & Tristan ( Lepidoptera : Gracillariidae ) (Cao et al. 2014).

Taxonomic remarks: Perry and Heraty (2021) synonymized Z. dulanense under Z. talitzkii stating that morphological differences between these species are of the intraspecific level. We, however, disagree with this synonymy and treat Z. dulanense as a valid species. There is a distinct hiatus in characters between Z. dulanense and Z. talitzkii . Thus, in female of Z. dulanense scape 4.0× as long as broad (3.7× in Z. talitzkii ), F1 1.0–1.1× long as F2 (1.6–1.8× in Z. talitzkii ), POL 1.6× as OOL (1.8× in Z. talitzkii ), STV 1.8–1.9× as long as PMV (3.0× in Z. talitzkii ), body pale yellow with whitish fontal face and pronotum ( Figs 5, 6) (body bright yellow in Z. talitzkii ; Figs 1–3). In male of Z. dulanense , F1 1.13× as long as F2 and 1.06× long as broad and F2 1.2× long as broad (F1=F2 and 2.0× long as broad in Z. talitzkii ), three black spots on Gt7 ( Fig. 9) (only one spot on Gt 7 in Z. talitzkii ; Fig. 4).
