Two new species of Chaerilus from southern Asia

 

Frantisek Kovarik and co-workers have recently published an article describing two new species of Chaerilus Simon, 1877 (Chaerilidae) from Laos and Thailand.

Chaerilus kautti Kovarik, Lowe, Stockmann & Stahlavsky, 2020 (Thailand)

Chaerilus pulcherrimus Kovarik, Lowe, Stockmann & Stahlavsky, 2020 (Laos)

Abstract:
Chaerilus kautti sp. n. from Thailand and C. pulcherrimus sp. n. from Laos are described and fully illustrated with color photographs of live and preserved specimens. C. kautti sp. n. is characterized by the unique combination of two characters: movable finger of pedipalp with 11 imbricated rows of granules; and pedipalp chela length/width ratio in male 4.55. C. pulcherrimus sp. n. is characterized by the unique combination of four characters: movable finger of pedipalp with 8 imbricated rows of granules; total length 16–19 mm; pedipalp chela length/width ratio in male 2.57, in female 2.69; and sternite VII smooth. In addition to analysis of external morphology and hemispermatophores, we also specify the number of chromosomes of both species: C. kautti sp. n. (2n=118) and C. pulcherrimus sp. n. (2n=102).
