Material examined. Holotype: ( NHMUK 1924.3.1.231) by monotypy. The type locality is State of Phatthalung, Malay Peninsula, without any further specification.
Diagnosis. Medium-sized, length 160 mm with 118 segments. Male pores in copulatory pouches, these with transversely slit-like, conspicuous openings, in XVIII. No genital markings. Spermathecal pores paired at 6/7–8/9, spermathecal ampullae inverted pear-shaped, diverticulum slender and greatly coiled towards distal end. No nephridia on the spermathecal ducts. Holandric, intestinal caeca simple, first dorsal pore in 12/13. Prostate glands large.

Remarks. This species is known only from one specimen. The detailed descriptions of Beddard (1900) and Stephenson (1932) were without illustrations, a line drawing of the spermatheca excepted ( Stephenson 1932: 229, Fig. 8 View FIGURE 8 ). In this study, we present illustrations of both the external ventral and internal dorsal view, including important features like the male genital characters and the prostate glands.
Metaphire perichaeta was first recorded from the State of Phatthalung (previously spelled Patalung), Malay Peninsula, but the locality is actually in Thailand, and M. khaoluangensis sp. n. is also found in Phatthalung. Differences of M. perichaeta are as follows: last oesophageal hearts in XII; spermathecae inverted pear-shaped; prostate glands and intestinal caeca smaller than those of the two new species with prostate glands situated on three segments in XVII–XIX (more than three segments in the new species) and intestinal caeca in XXVII– XXIV(XXVII–XXII in the new species). Moreover, M. perichaeta has a narrow mid-dorsal interruption in the ring of setae, while M. khaochamao has a mid-ventral interruption, and in M. khaoluangensis the ring of setae is continuous.
