1978] Thayer & Newton — Revision of Genus Glypholoma 53 
Male: Spatulate setae in pairs on protarsus, number unknown, 
singly on first two or three segments of mesotarsus, number 
unknown; genital segment and aedeagus as in figs. 68, 69, 80, 81. 
Distribution: See map (fig. 50). 
Holotype ( 6 ): CHILE: Malleco Prov., 20 km E Manzanar, 1100 
m, 19-25. XII. 1976, S. Peck, malaise trap [MCZ]. 
Paratype ( 9 ): Same data as holotype [CNC]. 
Habitat: Both specimens were collected in a malaise trap at the 
edge of moist Nothofagus forest (S. B. Peck, pers. comm.), but this 
species was absent from dung and carrion traps at the same locality 
which produced over 100 pustuliferum and one temporale. 
Etymology: This species is named after Dr. Stewart B. Peck, who 
collected both types as well as most of the other specimens used in 
this study. 
Glypholoma tenuicorne, new species 
With the characters of the genus as described above. 
Slightly convex dorsally, shape as in fig. 4, unicolorous light 
reddish-brown, head and pronotum dorsally with a few scattered 
setae, elytra glabrous except for macrosetae, tibiae and tarsi less 
densely setose than in other species. Length: 3 mm; width: 1.2 mm 
(one specimen seen). 
Head capsule generally similar to that of pustuliferum (fig. 58), 
but epistomal suture arcuate and lacking median stem. Antennal 
length about 2.2 times head width, first four antennal segments 
without dense pubescence, club lacking (see fig. 56). Ocellar di- 
ameter about 0.11 times head width. Labrum rectangular (anterior 
margin straight). Maxillary palp with fourth segment about 3.5 
times as long as third, the two subequal in width. 
Pronotum as in fig. 4, with shallow median and anterolateral 
depressions, lateral margins acute anteriorly, explanate posteriorly. 
Prosternum minutely rugose and sparsely punctate, without median 
longitudinal carina; pleural-sternal articulation possibly absent. 
Mesosternum with dense microsculpture, cavities for reception of 
procoxae about two-fifths the length of the mesosternum, meso- 
sternal process similar to that of pustuliferum (figs. 34, 36), 
extending half the distance between mesocoxae; mesosternal-pleural
