Contribution to our knowledge of the whitefly genus Aleuroclava Singh (Hemiptera: Aleyrodidae) in China, including Taiwan and Hong Kong, with descriptions of two new species Author Wang, Ji-Rui Author Du, Yu-Zhou text Zootaxa 2016 4138 2 332 348 journal article 10.11646/zootaxa.4138.2.6 2f8f4d43-64ef-422e-8f6f-97a9cfbfb6dc 1175-5326 263038 5569CE06-D1FE-4D4C-BFBF-6D98525F2B47 Aleuroclava rosae Wang & Du , sp. nov. ( Figs. 4–6 ) Puparium. Body white, elliptical, 0.914–1.15mm long, 0.786–0.998mm wide, broadest at the first abdominal segment region. Specimens were found 10–13 per leaf, centrally on the under surface of leaves. Margin. Smooth, emarginated at the both side of posterior margin. Crenulate, 22–24 crenulations in 0.1 mm . Paired anterior and posterior marginal setae about 5.6 µm and 6.2 µm long, respectively. Thoracic tracheal pore area protruded while caudal tracheal pore area emarginated. Dorsal surface. Submargin demarcated from dorsal disc not clearly. Submargin with a row of tuberculate papillae. Longitudinal and transverse molting suture reaching the margin. Cephalic setae 10–12 µm, first abdominal setae 8–10 µm, eighth abdominal setae 5–6 µm and caudal setae 36–38 µm long. Median tubercles present on abdominal segments III–V. Median length of abdominal segments VII shorter than VI. Some tubercles evident on sublateral part of abdomen and cephalo-thorax. Geminate pores present on dorsum. Vasiform orifice. Subcircular, slightly wider than long, 38.4 µm long, 49.2 µm wide, notched at the base; operculum subcircular, covering about full of the orifice, 28.8 µm long, 29.3 µm wide, concealing lingual. Caudal furrow distinct, about 153 µm long, 14.6 µm wide, with some papillae. FIGURE 4. Aleuroclava rosae sp. nov. , slide mounted specimen: (A) puparium; (B) margin; and. (C) median tubercles on abdominal segments, vasiform orifice and caudal furrow. Venter. A pair of ventral abdominal setae 4.6 µm long, 18 µm apart. Antennae extending near the base of prolegs. Adhesive pads present at apex of legs. Thoracic tracheal folds indiscernible, caudal tracheal folds indicated with many granulate. Host plants. Stranvaesia sp. ( Rosales : Rosaceae ) Distribution. China (Gaungxi). Material examined. HOLOTYPE : China , Guangxi, Maoer Mountain, 1 puparium on slide, on Stranvaesia sp., 22.vii.2015 , J. R. Wang ( YZU ). Paratypes : twenty paratypes , same data as the holotype , 20 puparia on 15 slides ( YZU , BMNH , USNM , TARI , MNHN ). Numerous dry puparia on Stranvaesia sp. with above collection data available at Yangzhou University. Etymology. The new species name refers to the family name of the host plant. Remarks. The new species differs from other species of Aleuroclava by the presence of the median tubercles on abdominal segments III–V. This species resembles A. tianmuensis Wang & Dubey in the overall shape but can be easily distinguished by the color, median tubercles of A. tianmuensis are present on abdominal segments II–VI; thoracic tracheal pore area protruded while that of A. tianmuensis emarginated. It is also resembles resembles A. takahashii (David & Subramaniam) but differs in the number of median tubercles and without a row of papillae along the submargin.
