擬平腹蛛科迄今為止已記述了77屬905種,主要分布于非洲、澳大利亞和亞洲(Platnick,2009).我國記述了5屬26種.赫拉蛛屬HeradionDankittipakul&Jocqué,2004全球共記述9種,分布于馬來西亞、越南和泰國,我國尚未見記述(Song,Zhu&Chen,1999;Dankittipakul&Jocqué,2004;Ono,2004;Chami-Kranon&Ono,2007).

在整理采自云南的標(biāo)本時(shí),鑒定出越南赫拉蛛Herad ion paradiseum(Ono,2004).該屬和種在我國屬首次記錄.觀察標(biāo)本保存在河北大學(xué)博物館.文中測量單位為mm.

觀察標(biāo)本：1♂,云南省麗江,1993-07-01,宋大祥采.

1雄蛛體長5.51：頭胸部長3.06,寬2.04;腹部長2.35,寬1.63.背甲深棕色,僅額前具幾根黑色長毛.8眼2列,2眼列均輕微后凹,后眼列比前眼列寬.每眼基部具黑色環(huán)斑.前側(cè)眼＞前中眼=后中眼=后側(cè)眼(0.10∶0.09∶0.09∶0.09);前中眼間距小于前中、側(cè)眼間距(0.04∶0.08),后中眼間距小于后中、側(cè)眼間距(0.06∶0.15).中眼域前邊小于后邊(0.19∶0.21),長大于寬(0.24∶0.21).額高0.51.螯肢前后齒堤無齒,紅褐色,末端黃褐色并具濃密黑色毛簇.顎葉紅褐色,末端黃褐色并具濃密黑色毛簇.下唇長大于寬(0.27∶0.26),紅褐色,末端黃褐色.胸板長小于寬(1.12∶1.22),紅褐色并具稀疏的黑毛,后緣分為2叉.步足的基節(jié)、轉(zhuǎn)節(jié)和腿節(jié)紅褐色,其余各節(jié)黃褐色.步足測量：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棕色縱斑,兩側(cè)各具3對白斑,后半部中央具1列縱向排列的白斑.腹部黃白色,具縱行和斜行的黑斑.紡器黃褐色.

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

觸肢脛節(jié)突指狀,輕微骨化.末梢的盾片突較寬.中突2分叉,基部的分支部分骨化并向外彎曲,上面的分支鐮刀狀并向內(nèi)彎.插入器鞭狀.

分布：中國(云南);越南.

討論：本觀察標(biāo)本與模式標(biāo)本具有以下不同：1)盾片突形狀不同;2)腹部背面的斑紋有區(qū)別.但是模式標(biāo)本采自越南的北方,本觀察標(biāo)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、跗舟溝、步足等相類似,因此筆者認(rèn)為是同一種.
