Etymology. The epithet honors Clarence J. Goodnight, who collected many of the species described in the present study.
Material examined. Holotype in preparation, MEXICO, Veracruz, Volcan San Martin, 1067 m, 14.vii.1953, C.J. Goodnight coll.; 1 paratype in preparation and 7 in alcohol.
Description. Size up to 3.0 mm.
Color pattern. Fifty years old ethanol preserved specimens (Fig. 3 E) display a reddish brown background color, with ill defined blue dots scattered throughout head, body and legs to femora; antennae and tibiotarsi solid light blue.
Head. Antennae up to 2.6x as long as head diagonal. Subapical sense organ of Ant. 4 minute, not nearly reaching upper margin of pit; guard sensillum normally large. Main sensilla on sense organ of Ant. 3 normal rods. Eyes apparently 6+6, eyes G and H unclear, maybe absent; eye valley with 4 ciliate chaetae (Fig. 11 B). Head dorsally (Fig. 11 A) with 5 anterior (A0, A2, A3, M2, S3) and 2 posterior (Pa5, Pm3) macrochaetae. Pre-labral chaetae weakly ciliate. Spines on distal margin of labrum absent. Labial triangle as M1M2rEL1L2A1-5: anterior chaetae smooth; chaeta r short, thick and smooth, all other posterior chaetae long and ciliate. Post-labial field with 6–7 chaetae between columns I and O.
Body. Body macrochaetae formula 73/0244+0+6. Mesothorax with 1 anterior (a5) and 6 posterior (p3 complex) macrochaetae (Fig. 11 C). Metathorax with 3 macrochaetae forming a triangle (Fig. 11 C). Abd. 1 chaeta a6 present. Abd. 4 (Fig. 11 F) with pseudopore in field between bothriotricha T2 and T4; inner macrochaetae A3, A5, B4 and B5 present; A3 well anterior to T2; A5 closer to pseudopore than B5; B4 closer to B5 than A5; laterally with 6 macrochaetae. Abd. 4 posterior chaetae up to 20+20.
Legs. Trochanteral organ square, with up to 38 chaetae. Metathoracic claw complex as in Fig 11 D: tenent hair spatulate; proportion tenent hair to unguiculus as 0.87. Unguis with 3 inner teeth; one inner basal tooth slightly longer; inner teeth spread as 34%, 35%, 62%; unpaired tooth as long or shorter than shortest basal tooth. Dorsal tooth absent; lateral teeth short, ending in basal fourth of outer edge of claw. Unguiculus lanceolate and smooth (Figs 11 D–E).
Furcula. Dens with 2 rows of ciliate spines: inner row with 30 spines; outer row with 24 spines. Mucro with 4 short sequential teeth (Fig. 11 G); 2.0x as long as width of tip of dens and ≈0.80x as long as hind claw.
Remarks. Trogolaphysa clarencei sp. nov. is the only species with 6–8 eyes, 5 anterior head macrochaetae in the combination A0, A2, A3, M2, S3, metathorax with 3 macrochaetae, Abd. 4 with 4 macrochaetae (A3, A5, B4, B5) with B4 inserted closer to B5 than A5, and distal margin of labrum without spine-like projections. Trogolpahysa clarencei sp. nov. is most similar to females of T. dimorphica sp. nov., the differences between the two forms are discussed in the remarks to the latter. Differences between T. clarencei sp. nov. and other species with 5 anterior macrochaetae are listed in Table 1.
