Nothoaspis reddelli Keirans and Clifford, 1975 , was described from 3 males collected in Grutas de Xtacumbilxunaán, Campeche, Mexico, although females have remained undescribed for 37 yr. Recently adult females of this species were collected from Cueva de Villa Luz ( = Cueva de las Sardinas, Cueva del Azufre), in Tapijulapa, Tabasco, Mexico. Here we present a morphological description of the female stage, together with 16S rDNA sequences that confirm the conspecificity of our female, male, and nymphal specimens. The female integument of the anterior portion of the dorsal surface is smooth (nothoaspis), appearing to consist of 3 large "subunits," 1 anterior and 2 posterior, each with a small sublateral "subunit" on either side. The remaining dorsal covered integument is a cell-like configuration. The hood is large and bluntly rounded, and visible dorsally. The spiracular plate is oval. It possesses 1 pair of posthypostomal setae. The palpal trochanter has 1 pair of setae and a 5/5 hypostome decreasing to 4/4 at the apex. There is a single central pore at the base of the hypostome.
红氏诺托蜱（Nothoaspis reddelli）由凯兰斯（Keirans）和克利福德（Clifford）于1975年描述，模式标本采自墨西哥坎佩切州的Xtacumbilxunaán洞穴中的3只雄性蜱虫，然而其雌性蜱虫在长达37年的时间里一直未被描述。最近，该物种的成年雌性蜱虫在墨西哥塔巴斯科州塔皮胡拉帕市的Villa Luz洞穴（即Cueva de las Sardinas洞穴、Cueva del Azufre洞穴）中被采集到。在此，我们给出该物种雌性阶段的形态学描述，并提供16S核糖体DNA序列，以证实我们所采集的雌性、雄性和若虫标本为同一物种。雌性蜱虫背面的前部体表光滑（诺托蜱属），似乎由3个大的“亚单位”组成，1个位于前部，2个位于后部，每侧各有1个小的亚外侧“亚单位”。其余被覆的背部体表呈细胞状结构。头罩大且钝圆，在背面可见。气门板呈椭圆形。有1对口下后刚毛。触肢转节有1对刚毛，口下板为5/5排列，顶端逐渐变为4/4排列。口下板基部有1个中央小孔。
