MALE. Unknown. Variation. The colour of the mesoscutellar-axillar complex is blue in the paratype. The body length of the paratype is 3.5 mm. In frontal view, the head is 1.09× as wide as high, the distance between the eyes below is 0.2× the distance between the eyes above; in dorsal view, the head is 1.5× as wide as long, with the interocular distance 0.2× the head width and 0.3× the width of an eye; in lateral view, the malar space is 0.4× the height of an eye; the distance between the toruli is 1.6× the distance between the torulus and the clypeal edge, and 1.5× the distance from the torulus to an eye. OOL:POL:LOL:MPOD = 1.0:1.5:6.6:5.8. The relative length(width) of antennal segments is: scape 86.5(15.8), pedicel 25.6(11.6), 1st to 8th flagellomeres: 9.6(10.0), 28.9(11.6), 33.3(11.8), 31.8(15.1), 23.8(18.9), 22.2(20.4), 18.4(21.6), 17.8(23.1), clava 46.2(29.1). cc:mv:pmv:stv = 4.0:3.4:1.6:1.0. Host. Unknown. Distribution. ORIENTAL: China (Fujian). Remarks. The fore wing colour pattern of females of this new species is very similar to females of Z. covid Jiang & Peng (Tang et al. 2022, fig. 1), with the following character states distinguishing females of the two species: 1) the body colour of Z. covid is black, much darker than that of Z. tianbaoyanensis, and it exhibits a strongly contrasting purple metallic luster on the pronotum, acropleuron, and occiput (in contrast, females of Z. tianbaoyanensis display a more greenish luster on these areas (Fig. 13A,C,F,G)); 2) the hind tibia of Z. covid is yellowish-white only in the basal third, whereas the hind tibia of Z. tianbaoyanensis is white except for a darker sub-medial band (Fig. 13A); and 3) the mesoscutellum of Z. covid features a coarsely reticulate sculpture with the cells aligned in a longitudinal orientation (Fig. 13I). This sculpture pattern of the mesoscutellar-axillar complex is common among most Chinese species of Zaischnopsis, whereas Z. tianbaoyanensis is distinguished by its uniquely finer punctate-reticulate sculptural pattern, characterized by clearly visible ridges between the individual cells both longitudinally and transversely (Fig. 13F).
