description: Scaphobaeocera monticola sp. n. Figs 27-30   
HOLOTYPE: Ƌ, Philippines: Luzon, Baguio, Mt. Santo Thomas, ca 2150m, 14.I.80, L. Deharveng & J. Orousset leg. # 198 (MHNG).  
PARATYPES: 1 Ƌ, 1 ♀, with the same data as the holotype; 1 Ƌ, Luzon, Mountain Prov., Mount Data Lodge 2250-2300m, 23-24.XII.79, L. Deharveng & J. Orousset (MHNG).  
DESCRIPTION: Length 1.20 mm, width 0.71-0.76 mm, dorsoventral diameter 0.71-0.75 mm. Body very dark reddish-brown to almost black, apices of elytra usually lighter, apical abdominal segments, legs and antennomeres I and II lighter, reddishbrown to ochraceous, antennomeres III to XI yellowish. Thorax, elytra and abdomen microsculptured and iridescent. Microsculpture on venter of thorax conspicuously coarse. Pronotal and elytral punctation very fine, hardly visible at magnification 100x. Length ratio of antennomeres as: III 5: IV 7: V 10: VI 8: VII 10: VIII 6: IX 10: X 10: XI 13. Segments III to VI evenly narrow, segment III about 2.5 times as long as wide, segments IV well 3 times as long as wide, V about 5 times as long as wide, VI about 4 times as long as wide. Segment VII about twice as wide as segment VI and almost 3 times as long as wide. Segment VIII slightly narrower than segment VII, about twice as long as wide. Segments IX and X wider than segment VII, each about 2.5 times as long as wide. Segment XI about 3 times as long as wide and as wide as segment X. Scutellum entirely concealed. Elytra with very fine parasutural striae, sutural striae starting posterior margin of pronotal lobe, not curved at base. Hypomeron without stria. Middle part of metaventrite flat, slightly impressed apically, without stria, with moderately dense, fine punctation and very short pubescence. Sides of metaventrite extremely finely punctate, with very short pubescence. Mesocoxal lines with very fine marginal punctures not extending laterally along mesepimera; submesocoxal areas about 0.02-0.03 mm long. Metepisterna flat, with exposed portion about 0.04-0.05 mm wide, parallel-sided, with straight, deep suture. Abdomen with distinct microsculpture consisting of transverse striae. Abdominal ventrite 1 extremely finely punctate, with basal punctures fine, not elongate. Tibiae straight  
Male characters. Protarsi with segments 1 to 3 distinctly widened, narrower than protibiae. Aedeagus (Figs 27-30) 0.39-0.41 mm long.  
HABITAT: Mountain broad-leaf forest, in rotten wood and humus, in moss on log.  
DISTRIBUTION: Philippines: Luzon.  
FIGS 22-30  
 (22, 23) Scaphobaeocera excisa sp. n., aedeagus in lateral view (22), internal sac in dorsal view, enlarged (23). (24-26) Scaphobaeocera hamata sp. n., aedeagus in dorsal and lateral views, internal sac (26) enlarged. (27-30) Scaphobaeocera monticola sp. n., aedeagus in dorsal and lateral views, internal sac (29, 30) enlarged. Scale bars = 0.1 mm.   
 COMMENTS: This species is characterized by the elytra with shortened sutural striae. In addition, its comparatively coarse thoracic microsculpture is diagnostic. The aedeagus in S. monticola is similar to that in S. data, see also comments under the latter species.
