Dicerapanorpa luojishana sp. nov. is distinguished by basal and mesal branches of paramere nearly reaching median tooth of gonostylus, lateral branch reaching basal tooth, and aedeagus exceeding apex of gonocoxite in male, and main plate of medigynium pear-shaped, twice as long as the posterior arm in female. The new discovery enriches the diversity of Dicerapanorpa and increases the species number to fifteen.记述分布于中国四川的双角蝎蛉属Dicerapanorpa Zhong&Hua,2013二新种。义君双角蝎蛉Dicerapanorpa yijunae sp. nov.的鉴别特征为雄虫阳基侧突基枝的基部内弯、端部平行,中枝和侧枝的端部向内弯曲,伸达生殖刺突的基齿;雌虫的生殖主板中部加阔,约与后臂等长。螺髻山双角蝎蛉Dicerapanorpa luojishana sp. nov.的鉴别特征是雄虫阳基侧突的基枝和中枝伸达中齿,侧枝伸达基齿,阳茎长度超过生殖基节顶端;雌虫的生殖主板梨形,长度约为后臂的2倍。双角蝎蛉属(Dicerapanorpa)物种数目增加至15种。
