Abstract

The genus Trichochloritis (family Camaenidae) was established by Pilsbry in 1891 based on the type species T. breviseta (Pfeiffer, 1862), with a distribution range extending from southern China down to the Indochina peninsula and extending to the Philippines. To date, 26 nominal Trichochloritis species have been recognized in the world. T. breviseta was discovered in Cat Tien National Park in May 2024, and this result is the first record for the fauna of Vietnam, its distribution range includes Thailand, Malaysia, and South Vietnam. This discovery has increased the number of nominal Trichochloritis species in Vietnam to nine. T. breviseta is characterized by its large size, depressed globular shell with a low, dome-shaped spiral; uniform color, yellow or yellowish brown, but lacking decorative color bands; the surface of the teleoconch is covered with soft, dense hair, along with many fine, granular ridges. The peristome is thick, wide, curved, and discontinuous. The umbilicus is wide, deep, funnel-shaped. The data in the study contribute to clarifying the zoogeography, phylogeny, distribution patterns, and phylogenetic relationships of the family Camaenidae in little-known regions such as Southern Vietnam.
