Larinia phosop new species 
(Thai name: Mangmoom-phosop).

Diagnosis. Larinia phosop n. sp. resembles L. fusiformis (Thorell 1877), but can be distinguished by following features. Male: 1) median apophysis V-shaped in ventral view (Figs. 4, 10, MA) vs. J-shaped (Fig. 18, MA); 2) conductor with finger-shaped chitinized projection (Figs. 4–5, 10–11, CD) vs. minute projection (Fig. 18, CD); 3) tegulum with small projection in retro-lateral view (Figs. 3, 9, a) vs. none (Fig. 17); 4) embolus almost hidden in retro-lateral view ...

Etymology. The specific epithet is derived from the Thai word “pho-sop”, which means the rice goddess in Thailand (Saenkattiyarat 2020); name in apposition.
