Background color in alcohol preserved specimens light brown; Ant. 2–4 blue, internatennal and postocular fields with scattered dark blue pigment; lateral margin of Th. 2–Abd. 2 and subcoxae on middle and hind legs blackish blue, tibiotarsi light blue, Abd. 4 with a characteristic transversal band and short paired, latero-posterior stripes. Head. Antennae up to 2.6x head diagonal. Subapical sense organ with guard sensillum robust and apically acuminate, sensillar pit present but sensillum not seen. Sensilla of Ant. 3 sense organ normal rods. Eyes 6–8 ( Fig. 15 B), eyes G and H reduced, seen only in largest individuals, eye valley with 4 ciliate chaetae. Head dorsally ( Fig. 15 A) with 3 anterior (A0, A2, S3) and 2 posterior (Pa5, Pm3) macrochaetae. Pre-labral chaetae serrate rather than ciliate. Labral chaetae smooth. Denticles on distal margin of labrum relatively long and separated ( Fig. 15 C). Labial triangle with M1M2rEL1L2A1–5; r stout and smooth all other posterior chaetae ciliate. Post-labial field with 6 chaetae between columns I and O . Body. Body macrochaetae 70/0243+0+ 6. Mesothorax with 1 anterior (a5) and 6 posterior (p3 complex) macrochaetae ( Fig. 15 F). Metathorax without macrochaetae. Abd. 1 chaeta a6 present. Abd. 3 S-microchaeta d2 inserted posterior to macrochaeta pm6 ( Fig. 15 I). Abd. 4 ( Fig. 15 H) pseudopore inserted in field posterior to bothriotrix T4; inner macrochaetae A3, A5, and B5 present; macrochaeta A3 anterior to T2; A5 closer to pseudopore than to macrochaeta B5; 6 lateral macrochaetae present. Posterior chaetae 12–13+12–13. Legs. Trochanteral organ with 22 chaetae. Metathoracic claw complex as in Figs. 15 D–E: tenent hair spatulate on all legs, 1.3X as long as unguiculus; claws with 4 inner teeth, one basal tooth slightly larger than other, proximal unpaired tooth prominent, as long as shortest basal tooth; inner teeth spread as 42%, 45%, 69%, 85%. Dorsal and lateral teeth ending on basal quarter of unguis. Unguiculus lanceolate, narrow ( Fig. 15 E) or weakly truncate ( Fig. 15 D). Furcula. Dens with 2 rows of ciliate spines: inner row with 32–33 spines; outer row with 21 spines. Mucro with 4 teeth, basal teeth paired ( Fig. 15 G); mucro square in shape, 1.8x as long as width of distal end of dens; females with mucro 0.77 x as long as inner margin of metathoracic unguis; male mucro 1.0x metathoracic unguis.

Remarks. Trogolaphysa balteata sp. nov. is unique among Neotropical species with 6–8 eyes in having 3 head macrochaetae in the particular combination A0, A2, S3, and a transversal band on Abd. 4. The color pattern of the new species is most similar to that of some individuals of T. geminata from Puerto Rico ( Mari Mutt 1987 ), but that species carries 4 dorsal head macrochaeta. Trogolaphysa giordanoae and T. sauron Soto-Adames, Jordana & Baquero, 2014 also have three dorsal head macrochaetae, but instead of S3 these species carry M2. In addition, T. giordanoae has three macrochaetae on Th. 3 (none in T. balteata sp. nov. ) and 4 macrochaetae on Abd. 4 ( 3 in T. balteata sp. nov. ), whereas T. sauron carries 3 macrochaetae on Th. 2 and the unguiculus is truncate (lanceolate in T. balteata sp. nov. ). Table 3 lists diagnostic characters for species with 3 anterior head macrochaetae.
