Hydatothrips flavidus sp. n.

( Fig. 3 )

Female macropterous: Body light yellow to brownish yellow, abdominal tergites II, III, V & VI grayish brown, IV whitish yellow, VII–X yellow, antecostal ridges on tergites II–VI dark brown, on tergite VII grayish brown; antennal segments I–III yellow, IV and base of V grayish brown, VI-VIII brown; forewings brown but lighter toward apex, with a sub-basal pale area; legs yellow.

Head short, dorsum with dense transverse striae with wrinkles between them. Occiput large, apodeme touching posterior margin of eyes, transverse striae on anterior portion, followed by reticulate sculpture, weak markings inside. Ocellar setae III situated just in front of posterior ocelli, outside ocellar triangle. Mouth cone narrow and long, reaching posterior margin of pronotum; maxillary palpi 3-segmented. Antennae 8-segmented, segments V and VI each with a linear sensorium.

Pronotum outside of blotch with reticles, some with inner dotted wrinkles; distance between two anteromarginal median setae less than or nearly equal to length of setae. Pronotal blotch covered with dense transverse striae, 3 pairs of anteromarginal setae, 1 pair of anterior submarginal setae, 1 seta each on lateral margin, 2 pairs of posteromarginal setae. Mesonotum with dense striae with wrinkles, metanotum with irregular reticles medially, with wrinkles. Forewing first vein setal row complete, second vein with 2 distal setae.

Abdominal tergite I with rows of microtrichia on sides; tergites II–VII with dense rows of microtrichia on areas lateral to submedian setae, tergites II–VI with posterior marginal comb, minute medially; tergites VII and VIII posteromarginal comb long and complete, sublateral of antacostal ridge on tergite II–VII with forwardly protruded spots. Sternites without discal setae.

Male: Similar to female in shape and structure; body length 0.96 mm on slide. Sternites VI & VII with transverse glandular area.

Measurements of holotype female in microns: Body length 1280. Head dorsum length 36. Pronotum length 108, width 192, blotch median length 68. Forewing length 780. Antennal segments I–VIII (L/W): 20/ 28, 32/28, 56/20, 60/20, 48/16, 56/16, 12/4, 12/4. Male body length 960, dorsum of head 28, forewing length 580.

Specimens examined: Holotype female: TAIWAN, Hsinchu, Wufeng , on Acacia confusa , 16-xii-1993.

Paratype: TAIWAN, Miaoli, Dahu , 1 male from Phyllostachys sp. , vi-1993 .

Remarks: Most of the species of this genus are in dark color, whereas this is a yellow species. Other characteristics are similar to H. multipunctatus , from which it can be distinguished by the short comb medially on tergites II–VI.
