Diagnosis

NYMPH. Characterized by a combination of the following characters: 1) labrum rectangular with rounded distolateral margins, distal medial margin with three protuberances; dorsal surface with 4 short and simple medial spine-like setae near distal margin; ventral surface with short medial spine-like setae near distal margin ( Fig. 10A, C View Fig ); 2) hypopharynx with lingua subquadrangular, elongated, with apical tuft of setae, subequal in length to superlingua ( Fig. 10G View Fig ); 3) maxillary palp long 2.0 × length of galea-lacinia; segment II without apical constriction ( Fig. 10H View Fig ); 4) labial palp with segment II with robust triangular distomedial projection, apically rounded, laterally directed; segment III triangular ( Fig. 10I View Fig ); 5) foreleg with anterior surface of femur with one row of 4 to 5 minute blunt setae, on basal half, near dorsal margin; claw I 0.6× length of tarsus I, with two row of denticles on basal third; 6) posterior margin of tergum IV with triangular spines, wider than long ( Fig. 11D View Fig ); 7) paraproct with several marginal spines, posterolateral extension with minute spines ( Fig. 11F View Fig ).

Etymology

The species name is a tribute to Dr Luana Araújo. She spoke out vehemently against the ineffective drugs used to treat COVID- 19 in the testimony to the CPI organized by the Brazilian Federal Senate in 2021.

Labrum ( Fig. 10A–C View Fig ): length 0.6× maximum width; rounded distolateral margins; distal medial margin with three protuberances; dorsal surface with 4 short and simple medial spine-like setae near distal margin, with one row of long, thin and simple setae near distal margin; dorsal surface covered with long, thin and simple setae; ventral surface with one row of robust spine-like setae near distolateral and distal margins; short medial spine-like setae near distal margin. Left mandible ( Fig. 10D–E View Fig ): incisors not fused; outer and inner set of incisors with 4 and 3 denticles, respectively; prostheca slender, bifurcated at apical middle; margin between prostheca and mola concave; subtriangular process wide with small protuberance on distal margin and 3 short spine-like setae at base; tuft of setae at base of subtriangular process; denticles of mola not constricted, with 4 prominent denticles in irregular sizes; lateral margin convex. Right mandible ( Fig. 10F View Fig ): incisors not fused; outer and inner set of incisors with 3 and 2 denticles, respectively; prostheca slender, bifurcated at apex; margin between prostheca and mola concave; tuft of setae at base of mola absent; denticles of mola not constricted; lateral margin convex. Hypopharynx ( Fig. 10G View Fig ): lingua subquadrangular, longitudinally elongated, apex covered with short setae, subequal to superlingua; superlingua oval, longitudinally elongated, with thin setae of different sizes on distolateral and distal margins. Maxilla ( Fig. 10H View Fig ): maxillary palp long 2.0 × length of galea-lacinia; segment I subequal to galea-lacinia; segment II with narrow base and apex, with thin and simple setae scattered on surface, without apical constriction; medial margin of galea-lacinia with 2 spine-like setae. Labium ( Fig. 10I View Fig ): glossa subtriangular, longer than paraglossa; dorsal surface with one longitudinal row of 8 short spine-like setae on apical ⅔ near inner margin; 1 robust spine-like seta on apex; longitudinal row of 5 robust spine-like setae on apical middle near outer margin; ventral surface covered with long, thin and simple setae. Paraglossa curved inward; dorsal surface with 1 long and robust spine-like seta on apex; longitudinal row of 9 long spine-like setae on apical ⅔ near outer margin and longitudinal row of 3 long and robust spine-like setae on apical middle near inner margin. Labial palp with segment I 0.6× length of segments II and III combined, covered with micropores (not illustrated); segment II with outer margin covered by thin, long and simple setae, inner margin bare; segment II with robust triangular distomedial projection, apically rounded, laterally directed; ventral surface of distomedial projection with tuft thin, long and simple setae; segment III triangular, length subequal to width, covered by thin, long and simple setae on outer margin, dorsally with one row of 8 robust spine-like setae near inner margin, ventrally with one row of 5 robust spine-like setae in near distal margin.

THORAX. Holotype pigment ( Fig. 9A–B View Fig ): light yellow; femur without mark. Legs ( Fig. 10A–C View Fig ). Femur: anterior surface with one row of 4 to 5 minute blunt setae, on basal half, near dorsal margin; ventral margin with one row of 3 to 4 elongated spine-like setae on basal third. Tibia: dorsal margin bare; ventral margin with one row of 6 to 7 spine-like setae. Patella-tibial suture present, from dorsal margin to ventral margin. Tarsus: dorsal margin bare; ventral margin with one row of 10 to 11 spine-like setae; tarsus I 1.2× length of tibia I; tarsi II and III length subequal to tibiae II and III.
