Hydatothrips meriposa sp. n.

( Fig. 5 )

Female macropterous: Body yellowish brown, abdominal tergites I–V grayish brown, VI whitish yellow, VII– X brown; antecostal ridges on tergites II–VII dark brown; antennal segments I, II and basal half of III–V whitish yellow, VI & VII grayish brown; forewings brown but lighter toward apex, with sub-basal pale area; legs yellow, mid femur brown medially, hind femur brown and lighter on both ends.

Head short, dorsum with dense transverse striae and wrinkles between them; occiput very short, with dense transverse striae, occipital apodeme not reaching posterior margin of eyes; ocellar setae III situated in front of posterior ocelli, inside ocellar triangle; mouth cone reaching posterior margin of pronotum; maxillary palpi 3-segmented. Antennae 7-segmented, segments V and VI each with a linear sensorium.

Pronotum outside of blotch with reticles, some reticles with dotted inner wrinkles, anteromarginal median setae wide apart, much longer than length of setae. Pronotal blotch with anterior and posterior margins concave, median length about 0.5 lateral length, covered with dense transverse striae, 1 pair of anteromarginal median setae, 2 pairs of anterior submarginal setae, 23 setae each on lateral margin, 1 pair of posteromarginal setae. Mesonotum and metanotum with dense striae and wrinkles. Forewing first vein setal row complete, second vein with 2 distal setae.

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

Male unknown.

Measurements of holotype female in microns: Body length 1140. Head dorsum length 64. Pronotum length 108, width 184, blotch median length 32. Forewing length 760. Antennal segments I–VII (L/W): 20/28, 40/24, 76/16, 68/12, 52/12, 64/16, 28/4.

Specimens examined: Holotype female: TAIWAN, Nantou, Hui-Sun Forest Station , on Murraya paniculata , 3-viii-1993.

Remarks: Though known only from one female, the clear body structures suggest that this is a valid species. Meriposa means butterfly, and describes the shape of the pronotal blotch of this species.
