Trigonuropoda latipilis species group Hirschmann, 1975 d : 55 . Type species. Trigonuropoda latipilis Hirschmann, 1975 g : 80, by original designation. Subgenus diagnosis. Species of the subgenus Latipilitrigon are easy to separate from the other species of Trigonuropoda on the basis of the following combination of characteristics: (1) the inner margin of the marginal shield is undulate, (2) anterior pit is absent on the dorsal idiosoma, and (3) caudal area is elevated from the neighbouring regions of the dorsal shield with 4–6 setae of a different type . The shape of the idiosoma oval, posterior margin rounded. The number of dorsal setae, excluding the marginal setae, is about 40. Varied types of setae, although most often are simple. Ornamentation of genital shield foveate or reticulate. Peritreme Mshaped, the anterior loop of the peritreme facing the front part of the idiosoma. Conspicuous characters are Y-shaped first hypostomal h1 , usually several times longer than h2 . Setae h3 simple, several times longer than h2 . Corniculi short, horn-like. Chelicera – the fixed digit is noticeably longer than the movable digit, and the nodus is also visible.
