Figs 1-5</p><p>Material.</p><p>Holotype. ♂ (RMBR), Vietnam, Lào Cai Province, Sa Pa Valley. Baited with cow dung at forest edge next to a small cascade alongside highway, ca. 850m along the road westward of the Thác bạc (Silver Waterfall) tourist attraction [22°23'23.90"N; 103°44'50.32"E, elevation 2600m above sea level, ASL]. Collected 16.VII.2010 (Ang Y). Paratypes. 2 ♂ (RMBR), collected from same locality and time as holotype.</p><p>Etymology.</p><p>The specific epithet refers to the shape of the main scleral plate for the 4th sternite, which resembles a cuirass or breastplate armor.</p><p>Diagnosis.</p><p>Adult male Perochaeta cuirassa is very similar to Perochaeta lobo and can only be reliably distinguished from the latter based on the 4th sternite [cf. Perochaeta cuirassa (Fig. 1) and Sepsis lobo (Fig. 6)]: The sternite in Perochaeta cuirassa lacks distinct lobes on the posterior end of the 4th sternite, while the sternite brush is thick and squat (as opposed to long and thin in Perochaeta lobo), and the main scleral plate is much broader (long as wide) than in Perochaeta lobo (twice long as wide). The hypopygium [cf. Perochaeta cuirassa (Figs 2-4) and Perochaeta lobo (Figs 7-9)] is also distinct, with Perochaeta cuirassa bearing a large median, decussating protrusion on the dorsal side of the surstylus, while Perochaeta lobo has a sub-median protrusion on the ventral side of the surstylus. Perochaeta cuirassa is also readily distinguished from all other Perochaeta species based on the morphology of the 4th sternite and hypopygium: The sternites brush of Perochaeta cuirassa (Fig. 1) has significantly more bristles (&gt;40 per brush) than either Perochaeta hennigi Ozerov, 1992 (Fig. 10) or Perochaeta dikowi (Fig. 12), both of which have only 5-6 large bristles in addition to a few weaker bristles. Perochaeta cuirassa also has strong bristles lining the distal margin of the sternite, which are not found in Perochaeta dikowi or Perochaeta hennigi . The surstylus of Perochaeta cuirassa (Fig. 2) resembles that of Perochaeta hennigi (Fig. 11), but can be distinguished by the large median surstylus projection, which is long and curved in Perochaeta cuirassa but short and broadly triangular in Perochaeta hennigi . Both Perochaeta dikowi (Fig. 13) and Perochaeta orientalis (De Meijere, 1913) (Fig. 14) lack large median projections. Perochaeta cuirassa can further be distinguished by the radial-medial cross-vein dividing the discal-medial cell which is in a ratio of 3: 1 in Perochaeta cuirassa, 2.5: 1 in Perochaeta dikowi, 2: 1 in Perochaeta hennigi and 1: 1 in Perochaeta orientalis .</p><p>Description (male).</p><p>Colour. Head capsule mostly black except for thin yellow strip along subgena and parafacial area. Lunule, facial carina and antennae light brown; antennal groove dark brown. Proboscis brown.

A Y-shaped apodeme extends underneath and anterior to the 4th sternite.</p><p>Hypopygium (Figs 2-4). Cercal plate with two very weak lobes; distal margin of each lobe covered with numerous setae.

The structure of the hypopygium (Figs 7-9) is also diagnostic given that it is the only Perochaeta with a surstylus that has a dorsal flap along its length and a long distal-pointing projection sub-basally.

(2) The basal lamina-like projection on the fore tibia of Sepsis spura (Figs 25, 27) merges back with the tibia gently, but ends off with a distinct lobe in Sepsis nitens (Fig. 22). The short spines found posteriorly on the projection are also much weaker than those found in Sepsis nitens . (3) Sepsis spura (Figs 25, 27) has only one anterior lamina-like protrusion on the distal portion of the fore tibia, while Sepsis nitens (Fig. 22) has such protrusions on both anterior and posterior sides. (4) The surstylus of Sepsis nitens (Fig. 23) has a rather angular basal swelling and is relatively straight, curved only at the terminus, while the surstyli of Sepsis spura (Figs 30, 31) has a rounded basal swelling and is medially curved for the entirety of the surstylus.
