description: <b> <i>Mallinella chengjiaani</i> Barrion, Barrion-Dupo &amp; Heong, new species</b> [Figure 53 A-E] <i>FEMALE.</i> Holotype female, total length 7.30mm. Cephalothorax length 3.60mm, width 2.40mm, height 1.70mm.Abdomen length 4.25mm, width 2.85mm and height 2.10mm. <i>Carapace.</i> Reddish black with a median reddish brown band running from eye area to fovea, oblongate and 1.5 x longer than wide. Cephalic area rounded anteriorly. Chelicerae reddish brown, 1.7 x longer than wide (1.43: 0.86mm), broad base 2 x wider than its apical width. Pedipalps concolorous with brownish legs and sternum, tarsus heavily spinedretrolaterally and ventrally.Maxillae longer than wide, light reddish brown with yellow apical one -third converging.Labium triangular with yellow apex. Chilum triangular. Sternum as long as wide. <i>Eyes.</i> In three rows, ALE in the first row of two eyes, PLE and AME in second row of 4 eyes and PME in the third with 2 eyes. Both AER and PES rows strongly procurved. PLE and AMEs almost in a straight line. Eye diameter (mm): AME (0.21)&gt; ALE (0.18)&gt; PME = PLE (0.16). Eye separation (mm): PME-PLE (0.33)&gt; AME-PLE (0.14)&gt; AME-ALE (0.13)&gt; PME-PME (0.12)&gt; AME-AME (0.08)&gt; ALE-PLE (0.07). Median ocular quad wider in front than behind (0.47 mm vs 0.43 mm) and 1.19 x longer than frontal width. Clypeus height nearly 3 x AME diameter along ALE and 3.7 x AME diameter at AME area. <i>Legs.</i> Brownish red with dark reddish brown femora I-IV. Tibia I with 4 ventral spines, II with 3 retrolateral and 6 ventral spines, III with 3-6 - 4 - 3, and IV similar to III except for having 4 retrolateral spines. Femur III and metatarsus III subequal. Leg formula 4132. Leg measurements (mm): <i>Abdomen.</i> Globose, black dorsally with white longitudinal and irregular venter with two white longitudinal bands. Spinnerets uniformly yellow and relatively short. Epigynum with transverse lip-like plate and a pair of subparallelspermathecae with inner coils. <i>MALE.</i> Unknown. <i>Material Examined</i>. Holotype female, (coll. no. S0 58), CHINA, Hainan Island, Panja Town, Songtao Reservoir, 3 April 2011, AT Barrion, JLA Catindig, SC Villareal; paratype one female (coll. no. La 2), Laocheng, Hongji Village, 24 April 2012, AT Barrion, JLA Catindig, SC Villareal; paratype one female (coll. no. Ha 2012 - 1), Haiko, 9 April 2011, AT Barrion, JLA Catindig, SC Villareal. <i>Diagnostic Features.</i> <i>Mallinella chengjiaani</i> Barrion, Barrion-Dupo &amp; Heong new species is similar to <i>M. panchoi</i> (Barrion &amp; Litsinger, 1992) but differs from the latter in having (1) elongated and inner-coiled spermathecae, (2) femur III as long as metatarsus III, and (3) tibial supination. For example, tibia I-IV of female <i>M. panchoi</i> has 4 ventral spines while M. chengjiaani tibia II has 6 ventral spines. <i>Etymology.</i> Patronym, in honor of Dr. Jiaan Cheng, in recognition of his outstanding legacy in improving the ecological management of rice insect pests in China, particularly, the highly invasive rice planthoppers.
