Lef paramere smaller than right, curved; basal process narrow; body straight or with slight constriction before apical process; apical process tapering. Right paramere curved, wider than lef; basal process narrow; body wide, in some species with projections; apical process reduced to well developed. Aedeagus small and simple; phallotheca sclerotized; seminal duct widened basally, not folded, sclerotized posterior to its distal curvature, ataining at least apex of phallotheca; endosoma completely sclerotized or only on distal half.

Distribution: Argentina, Brazil, Ecuador, and Venezuela ( Fig. 8).

Etomologo: Te generic name refers to the punctate collar and it is formed by the combination of the Latin words ‘ puncti ’ (points) and ‘ collus ’ (neck). Te gender is masculine.

Discussion: Puncticollus gen. nov. includes two species transferred from Neella , N. anduzeei and N. rondonia , and a new as yet undescribed species. In our analysis it is recovered as the sister-group of Neoneella and is supported by 15 synapomorphies: six continuous characters:the total length (0:0.473) and the relations, clypeus length/head height (3: 0.039 –0.041), labial segment I length/vertex width (8: 0.077 –0.096), labial segment II/total labial length (9:0.025), cuneus length/anterior cuneal margin width (15: 0.147 –0.148), and female subgenital plate length/anterior margin width (19: 0.172 –0.213); and nine discrete contradictory synapomorphies: upper margin of eyes achieving the head dorsal margin (20:0), frons globose (30:1), antennal segment I with one type of setae (35:1), labium ataining mesocoxae (40:1), humeral angles separated from posterior pronotal lobe by a deep longitudinal depression (52:1), metafemora expanded at base (86:1), genital capsule with a reduced opening (110:1), phallotheca completely sclerotized (145:2), and female subgenital plate truncate (153:2). Te GC frequencies indicate a high support due to low contradictory information ( Fig. 7).

Puncticollus gen. nov. runs to the couplet 8 in the key to the Neotropical eccritotarsine genera ( Carvalho and Ferreira 1995), where Hesperolabops and Aztecarina are identified. Puncticollus gen. nov. can be distinguished from the two aforementioned genera by the slightly stylate eyes, the pronotum not strongly narrowed or constricted anteriorly and with the posterior margin straight, and the hemelytra impunctate and yellowish white to orange.

Tope species: Tomasomiris setosus Mingheti et al., 2024 . By monotypy and original designation.

Tomasomiris Mingheti et al., 2024: 2–4 (original description; figs).

Discussion: Tis genus was recently described to include the type species from Panama. Tomasomiris is recovered at the base of the clade including Caulotops, Pachopoda , Proneella , Naelle gen. nov., Neella , Laterocavocoris gen. nov., Lelena gen. nov., Egerocoris , Puncticollus gen. nov., and Neoneella . It is supported by 16 synapomorphies. Seven continuous characters: the total length (0: 0.655 –0.666), and the relations: labrum length/labial segment I length (4: 0.018 –0.030), antennal segment I, length/ antennal segment II (6: 0.438 –0.453), scutellum, anterior margin width/scutellum length (12: 0.119 –0.126), corium, medial fracture length/corium length (14: 0.008 –0.009), cuneus length/anterior cuneal margin width (15: 0.096 –0.100) and female subgenital plate length/anterior margin width (19: 0.026 – 0.055); and nine discrete contradictory synapomorphic characters: eyes projected anteriorly (24:2), posterior margin of pronotum convex (51:0), hemelytra with erect setae (62:2), membrane cell with medial angle acute (77:1) and with its posterior margin slightly concave (79:1), calli of pronotum of different coloration than posterior pronotal lobe (154:0), hemelytra with a black central spot (156:1), cuneus with laterals and/or posterior margins brown to black (157:1) and distal extreme of femora with a brown to black dorsal spot (159:1).
