Tegulinus gen. nov.

Type species: Tegulinus sumatranus sp. nov.

Etymology: The generic name is derived from the Latin “tegulum”, the shape of which is a main character of the genus; the gender is masculine.

Diagnosis: The new genus belongs to the subfamily Erigoninae and is characterized by the following combination of characters: Rather large-sized spiders, total length 1.90-2.25. Chaetotaxy formula 2.2.1.1, all metatarsi with a trichobothrium. Carapace and palpal tibia of males modified; sulci and mastidion absent. Tegulum strongly protruded downwards; distal suprategular apophysis well-developed, long, narrow; embolus small; convector present, simple.

Species included: Tegulinus sumatranus sp. nov. and T. bifurcatus sp. nov.

Taxonomic remarks:

The taxonomic position of

this new genus is unclear, especially as the female is unknown. The conformation of the embolic division, namely the shape of the small embolus and the structure of the convector , somewhat resembles that of some Oriental species of Oedothorax Bertkau in Förster & Bertkau, 1883 , e.g., O. meghalaya Tanasevitch, 2015 or O. stylus Tanasevitch, 2015 . The discovery of congeneric females and/or other representatives of Tegulinus gen. nov. should clarify the position of the genus among the Erigoninae .

Distribution: Known only from Sumatra Island, Indonesia.
