description: <b> <i>Chrysso hyoshidai</i> Barrion, Barrion-Dupo &amp; Heong, new species</b> [Figure 38 A-E] <i>FEMALE.</i> Holotype female, total length 2.50 mm. Cephalothorax length 0.90 mm, width 0.70 mm. Abdomen length 1.45 mm, width 0.95 mm. Paratype female, total length 3.20 mm. <i>Carapace.</i> Yellow with a red median U-band and eye margins, 1.3 x longer than wide. AME black. Chelicerae yellow with a short yellowish brown and sharply pointed fang. Promargin bears a bifurcate tooth. Retromargin toothless. Pedipalps yellow with a single claw on tarsus. Maxillae yellow, longer than wide, converge apically. Labium dark yellow with a truncate apical margin. Sternum yellow, longer than wide with rounded posterior end. <i>Eyes.</i> In two rows of four each, strongly recurved AER slightly shorter than procurved PER. Eye diameter (mm): AME (0.10)&gt; PME (0.09)&gt; ALE=PLE (0.06). Eye separation (mm): AME-AME (0.09)&gt; PME-PME (.07)&gt; PME-PLE (0.06)&gt; AME- ALE (0.023). Clypeus height 1.43 x AME diameter. <i>Legs.</i> Yellow, relatively long and slender with few black, long and spatulate spines. Femur I has eight small dotted transverse gray bands ventrally and femur II with one subapicoventral band. Tibiae with two subapical ring gray bands. Anterior tips of metatarsi I-IV black. Tibia I and II with two dorsal spines each, III and IV each with one. Dorsal spines on patella I apical and basal in II, III and IV. Femur I as long as metatarsus I. Leg formula 1423. <i>Abdomen.</i> White dorsally with a black bottlelike median band and three reddish black transverse bands along cardiac area, basal two of three transverse bands formed transverse U-shaped anterolateral process attached to the black median band. Posterior hump-like and bulbous, bears two pairs of long spatulate spines posterolaterally. Abdomen triangular laterally, white with two black spots apically and yellow basally. Venter uniformly yellow. Epigynum with a pair of black sickle-shaped bands facing each other and slightly visible rounded spermathecae in uncleared state. Spermathecae rounded with insemination ducts arise slightly midanterolaterally of spermathecae and loops C-shaped posteriorly developing two to three coils prior to the fertilization duct. <i>MALE.</i> Unknown. <i>Material Examined</i>. Holotype female (coll. no. Da 2010 - 4), CHINA, Hainan Island, Danzhou, 9- 13 August 2010, ATBarrion and SCVillareal, and one paratype female (coll. no. Da 5), 4 April 2011, ATBarrion, JLACatindig and SCVillareal; Haiko, one paratype female (coll. no. a 2011 - 9) 9 April 2011, ATBarrion, JLACatindig and SCVillareal. <i>Diagnostic Features.</i> This species closely resembles <i>Chrysso spiniventris</i> (O. P.-Cambridge, 1869) and <i>C. lingchuanensis</i> Zhu, and Zhang, 1992 but differs from both taxa in the following features, namely, (1) more truncated posterior end of abdomen, (2) presence of a red U-band on carapace, (3) only two pairs of abdominal spines posterolaterally, (4) slightly midanterolateral origin of insemination ducts from spermathecae, (5) femur I as long as metatarsus I, and (6) presence of a "bottle-like" black dorsal band on midabdomen. <i>Etymology.</i> Patronym, in honor of Dr. Hajime Yoshida’s magnificent contributions in the systematic of Japanese Theridiidae and nearby countries.
