拟平腹蛛科迄今为止已记述了77属905种,主要分布于非洲、澳大利亚和亚洲(Platnick,2009).我国记述了5属26种.赫拉蛛属HeradionDankittipakul&Jocqué,2004全球共记述9种,分布于马来西亚、越南和泰国,我国尚未见记述(Song,Zhu&Chen,1999;Dankittipakul&Jocqué,2004;Ono,2004;Chami-Kranon&Ono,2007).

在整理采自云南的标本时,鉴定出越南赫拉蛛Herad ion paradiseum(Ono,2004).该属和种在我国属首次记录.观察标本保存在河北大学博物馆.文中测量单位为mm.

观察标本：1♂,云南省丽江,1993-07-01,宋大祥采.

1雄蛛体长5.51：头胸部长3.06,宽2.04;腹部长2.35,宽1.63.背甲深棕色,仅额前具几根黑色长毛.8眼2列,2眼列均轻微后凹,后眼列比前眼列宽.每眼基部具黑色环斑.前侧眼＞前中眼=后中眼=后侧眼(0.10∶0.09∶0.09∶0.09);前中眼间距小于前中、侧眼间距(0.04∶0.08),后中眼间距小于后中、侧眼间距(0.06∶0.15).中眼域前边小于后边(0.19∶0.21),长大于宽(0.24∶0.21).额高0.51.螯肢前后齿堤无齿,红褐色,末端黄褐色并具浓密黑色毛簇.颚叶红褐色,末端黄褐色并具浓密黑色毛簇.下唇长大于宽(0.27∶0.26),红褐色,末端黄褐色.胸板长小于宽(1.12∶1.22),红褐色并具稀疏的黑毛,后缘分为2叉.步足的基节、转节和腿节红褐色,其余各节黄褐色.步足测量：Ⅰ8.05(2.24+0.61+2.04+1.73+1.43);Ⅱ6.63(1.94+0.51+1.43+1.53+1.22);Ⅲ6.53(1.73+0.61+1.33+1.84+1.02);Ⅳ9.07(2.14+0.61+2.14+2.65+1.53).足式：4123.腹部梨形.背面黑褐色,前半部中央具1棕色纵斑,两侧各具3对白斑,后半部中央具1列纵向排列的白斑.腹部黄白色,具纵行和斜行的黑斑.纺器黄褐色.

图1 越南赫拉蛛 Heradion paradiseum(Ono,2004)

触肢胫节突指状,轻微骨化.末梢的盾片突较宽.中突2分叉,基部的分支部分骨化并向外弯曲,上面的分支镰刀状并向内弯.插入器鞭状.

分布：中国(云南);越南.

讨论：本观察标本与模式标本具有以下不同：1)盾片突形状不同;2)腹部背面的斑纹有区别.但是模式标本采自越南的北方,本观察标本采自云南省,其地理位置接近越南的北方.并且其他部位的特征如：中突、跗舟沟、步足等相类似,因此笔者认为是同一种.
