Specimens preserved in alcohol for 64 years light brown, patternless ( Fig. 3 G). Head. Antennae relatively short, 0.83x as long as head. Subapical sense organ of Ant. 4 not seen. Sense organ of Ant. 3 with normal rods. Eyes 3+3, eyes; only eyes A, B and C remain ( Fig. 20 A). Eye valley with 1 ciliate chaeta. Head dorsally with 2 anterior (A0, A2) and 2 posterior (Pa5, Pm3) macrochaetae. Pre-labral chaetae ciliate. Distal margin of labrum smooth, without denticles. Labial triangle with M1M2rEL1L2A1–5: anterior chaetae smooth; r stout and smooth, all other posterior chaetae ciliate. Post-labial field with 5–6 chaetae between columns I and O . Body. Body macrochaeta formula 60/0243+0+4. Mesothorax with 1 anterior (a5) and 5 posterior (p3 complex) macrochaetae ( Fig. 20 B) Metathorax without macrochaetae. Abd. 1 chaeta a6 absent. Abd. 3 S-microchaeta d2 almost reaching bothriotrix m5 ( Fig. 20 E). Abd. 4 ( Fig. 20 F) with pseudopore in field posterior to T4; with inner macrochaetae A3, A5, B5; A 3 in field between T2 and T4; A5 closer to B5 than to pseudopore; lateral macrochaetae D3, E2, E3 and F1 present. Abd. 4 posterior chaetae 10+10. Legs. Trochanteral organ V-shaped, with up to 14 chaetae. Metathoracic claw complex as in Fig 20 C; tenent hair acuminate, 0.56x as long as unguiculus; with 3 inner teeth, all keel- to weakly lunate-shaped, one paired tooth larger than other, longest tooth almost reaching unpaired tooth; all teeth originating around middle quarter of inner edge, teeth spread as 42%, 47%, 57%. Unguiculus weakly truncate and basally swollen, posterior edge smooth. Furcula. Dens with 2 rows of ciliate spines: inner and outer rows with 15 and 12 spines respectively. Mucro with 4 teeth, basal teeth paired ( Fig. 20 D); mucro rectangular, 3.0x as long as wide, and 1.4x as long as inner margin of metathoracic unguis. Remarks . Trogolaphysa trioculata sp. nov. is the only Neotropical member of the genus with 3+3 eyes, acuminate tenent hair and 4 large lateral macrochaetae on Abd. 4. Five other species have reduced number of eye: T. alleni Yoshii, 1988 and T. millsi Arlé, 1939 with 2 eyes, T. tijuacana Arlé & Guimarães, 1979 with 4 eyes and T. strinatii Yoshii, 1988 with 5 eyes. Descriptions for all the species mentioned above are incomplete, but details of characters distinguishing them are presented in Table 5 .
