description
Description: Male (holotype). Total length 1.80. Carapace 0.85 long, 0.60 wide, pale greyish brown. Cephalic part of carapace somewhat elevated and protruded forward as shown in Fig. 1. Eyes slightly enlarged. Chelicerae 0.33 long, unmodified. Legs pale brown. Leg I 3.46 long (0.93 + 0.25 + 0.85 + 0.78 + 0.65), IV 3.22 long (0.88 + 0.23 + 0.83 + 0.80 + 0.48). Chaetotaxy 2.2.1.1, length of spines about 1.5 times diameter of segment. All metatarsi with a trichobothrium. TmI 0.63. Palp (Figs 2 - 7): Tibia carrying a wide dorsal apophysis with a small invagination apically and two small tubercles retrolaterally. Paracymbium somewhat L-shaped. Distal surface of tegulum membranous. Distal suprategular apophysis short, wide, rounded distally. Embolus very short, radix relatively large, cylindrical, with a fold on its exterior surface. Convector with a wide lateral extention and a short, pointed distal apophysis. Main body of convector long, tapering posteriorly. Abdomen 1.15 long, 0.63 wide, dorsally pale, with an indistinct grey herring-bone pattern. Female. Unknown. Taxonomic remarks: Oedothorax khasi sp. nov. is similar to another Oriental species, O. myanmar, recently described from mountains of the Chin State in Myanmar (Tanasevitch, 2017). The new species is clearly distinguished by the shape of the dorsal apophysis on the palpal tibia, as well as by the relatively large and not curved radix.
diagnosis
Diagnosis: The new species is characterized by an essentially unmodified carapace, by the shape of the dorsal apophysis of the palpal tibia, as well as by a relatively large, cylindrical radix and by a very short embolus.
distribution
Distribution: Only known from the type locality in northern India.
etymology
Etymology: The specific name is a noun in apposition referring to the mountain range in which lies the type locality.
