About Tylorida ventralis (Thorell, 1877)
Tylorida ventralis shows considerable intraspecific variation in coloration, with two recognized main color morphs (Silver and Yellow) plus three distinct varieties. In Thorell's original description, females have a body length of approximately 7 millimeters, while males reach around 4.75 millimeters.
The female cephalothorax is pale testaceous, with darkened lateral margins and a median longitudinal band on the thoracic portion. When viewed from the side, the female abdomen is oblong, with a broadly truncated posterior end and the upper-posterior angle raised into a small tubercle or cone. The abdomen is sub-testaceous or greyish, with scattered white and black spots across its surface. On the ventral side, two large sub-rectangular black spots run along the midline, with irregular black spots on each side.
Males are longer and narrower in body shape than females, and have longer legs. Male chelicerae are distinctive: they are narrower and slightly longer than female chelicerae, with a strong tooth on the inner side. Male palps are long and slender, with a large, thick, shortly sub-ovate bulb.
Tylorida ventralis has been recorded in Pakistan, India, China, Myanmar, Thailand, Laos, Japan, Taiwan, and New Guinea. This species has a wide distribution across tropical and subtropical Asia, with records extending from the Indian subcontinent through Southeast Asia to the Western Pacific.
