Abstract. Four new species of the genus Caccothryptus (Coleoptera: Limnichidae) are described: C.
taiwanus from Taiwan; C. orion from Okinawa; C. tibetanus and C. chayuensis from Tibet. All the
species belong to the testudo species group ( sensu Hernando & Ribera 2014). Additional specimen
data and an updated species list are also given, and C. testudo Champion, 1923 is newly recorded from
Thailand.
Key words. Limnichidae, taxonomy, distribution, new species.

Introduction
The family Limnichidae, minute marsh-loving beetles, is aquatic and semiaquatic, and represented by
about 400 species belonging to 37 genera (Spangler et al. 2001; Hernando & Ribera 2005b). The species
diversity of this family is high in the Neotropical and the Oriental Regions (Hernando & Ribera 2005b),
but the Oriental fauna of this family has not been well studied.
The Oriental genus Caccothryptus Sharp, 1902 was recently revised (Hernando & Ribera 2014), and 20
species subdivided into 5 species groups were recognized. In the present paper, I describe 4 additional
new species from Okinawa, Taiwan and Tibet.
Materials and methods
General observations and dissections were made under aLeicaMZ95 stereo microscope. Microstructures
of dissected parts were studied in pure glycerine under an Olympus BH-2 compound microscope. After
observation, the dissected parts were mounted on the same card as the specimen. Photographs were
taken under a Leica MZ95, using a microscopy camera system (Nikon DS-Fil-L2), and combined with
automontage software Combine ZM (Alan Hadley, UK).
The specimens examined are preserved in the following museums:

Hernando & Ribera, 2005, Mandersia Sharp, 1902 and Euthryptus Sharp, 1902. It is also similar to

Discussion
Including the species described in this paper, it is now established that 24 species of the genus
Caccothryptus are distributed in Japan (Okinawa), Taiwan, China, Tibet, Vietnam, Thailand, Nepal,
Cambodia, India, the Philippines, Malaysia and Indonesia (see also appendix). The distribution of
Caccothryptus tibetanus sp. nov. and C. chayuensis sp. nov. in Tibet is the northernmost record of the
genus.
