Diagnosis. Tricorythodes carare differs from the others species by the following combination of characteristics: maxillary palp 3-segmented, with apical setae ( Fig. 4E View FIGURE 4 and 7B View FIGURE 7 ); dorsal surface of median and hind femora with a longitudinal row of 5 to 9 chalazae serrated in the apex ( Figs. 5C–D View FIGURE 5 ); tarsal claws with 4 or 5 marginal denticles and with 1–3 submarginal denticles near apex ( Figs. 5A View FIGURE 5 and 6B–D View FIGURE 6 ) and median and hind tarsal claws with one submarginal denticle ( Figs. 6E–F View FIGURE 6 ); posterior margin of the abdominal terga with chalazae serrated in the apex ( Figs. 7C–D View FIGURE 7 ).

Holotype mature male nymph: Length of male, 5.0– 5.4 mm; body (without filaments), 2.9–3.3 mm; caudal filaments, 2.0–3.0 mm; length of female, 5.9–6.8 mm; body (without filaments), 3.2–3.5 mm; caudal filaments, 2.6–3.3 mm (n=6). General coloration whitish, with diffuse gray ( Fig. 3A View FIGURE 3 ). Head. Genal projection little developed. Head whitish with occipital region shaded with gray ( Figs. 3A View FIGURE 3 ). Antennae translucent. Mouthparts yellowish ( Fig. 4 View FIGURE 4 ); maxillary palp 3-segmented with an apical seta ( Fig. 4E View FIGURE 4 and 7B View FIGURE 7 ). Thorax. General coloration whitish shaded gray ( Figs. 3A View FIGURE 3 ). Pronotum shaded with gray, except by the lateral margin of pronotum not pigmented; anterior margin of pronotum with simple, thin, scattered setae. Mesonotum whitish shaded with gray, except midline and the inner margin of the wing pads; wing pads whitish, shaded with gray, with veins and external margin dark gray. Metanotum whitish and shaded with gray. Legs ( Figs. 5B–D View FIGURE 5 and 6A View FIGURE 6 ): general coloration pale with diffuse gray. Femora relatively wide with total length/ maximum width ratio forelegs = 1.5–1.7 and mid and hind legs = 1.9–2.2. Fore femur with a submedian transverse row of 6 to 13 chalazae, and with a longitudinal row of 2 to 5 chalazae, inner margin with acuminate and simple setae, outer margin with chalazae and acuminate setae ( Fig. 5B View FIGURE 5 ). All chalazae present serrated apex. Middle and hind femora with a transverse row of 4 to 8 chalazae and acuminate setae in the basal region; dorsal surface with a longitudinal row with 5 to 9 chalazae; inner and outer margin with chalazae and acuminate setae ( Figs. 5C–D View FIGURE 5 ). Tibia: pale with a darker gray band in the middle; dorsal surface with a longitudinal row of 4 to 6 acuminate setae ( Figs. 5B–D View FIGURE 5 and 6A View FIGURE 6 ), apex with branched pectinate setae; inner and outer margins with simple and acuminate setae. Tarsi: pale coloration, with a gray band in the middle; apex with branched setae; inner and outer margins with simple setae ( Figs. 5B–D View FIGURE 5 ). Claw ( Figs. 5A View FIGURE 5 and 6B–F View FIGURE 6 ): pale yellow coloration, with dark apex; 4 to 6 marginal denticles; apex with a small and simple seta ( Figs. 5A View FIGURE 5 and 6C View FIGURE 6 ). Fore claw: with 1–3 subapical denticles ( Figs. 5A View FIGURE 5 and 6B–D View FIGURE 6 ). Middle and hind claw: with one subapical denticle ( Figs. 6E–F View FIGURE 6 ). Thoracic pleurae and sterna pale shaded lightly with grey. Abdomen. General coloration whitish shaded with gray, except on lateral margins and midline of the tergites VII–IX ( Figs. 3A–B View FIGURE 3 ). Dorsal surface of the terga with small chalazae and numerous small setae ( Fig. 7C– F View FIGURE 7 ). Posterior margins of abdominal terga with numerous spines and small chalazae ( Figs. 7C–D View FIGURE 7 ). Tergum I elevated in middle region, tergum II– VI with less marked median elevation. Terga II–IX laterally expanded, with posterolateral projections present on segments VI –IX ( Figs. 3A–B View FIGURE 3 ). Abdominal sterna pale, with slight grayish tinge, with a dark submedian longitudinal band in sterna I–VIII. Opercular gill subtriangular, pale, with extensive diffuse gray marks. Caudal filaments pale with dark yellow base, posterior margin of each joint with simple and acuminate setae.

Note. Some specimens are shaded with reddish instead of gray ( Fig. 3B View FIGURE 3 ).

Adults. Unknown.
