Holotype with left wing mounted on microslide with Canada balsam. Left antenna and terminalia were placed in a microvial with glycerin, both pinned along the specimen.

Diagnosis. Trochanters yellow; femora mostly brown, yellow on proximal half; tibiae yellow; hind tibia with erect setae medially. Abdomen brown, tergite 1 entirely gray pruinose and tergites 2–5 gray pruinose posterolaterally. Surstyli subsymmetrical, both with tips inward directed and inner margin with lobes that converge apically. Apex of phallic guide stout, long, with distinct translucent lobes dorsally and ventrally. Phallus trifid, long, with apex of ejaculatory ducts coiled.

LW/MWW = 3.3; LTC/LFC = 2.6. Membrane faintly brown infuscated; third section costal longer than the length of fourth; vein r-m located after the basal third of the upper section of the cell dm; vein M 2 long; dm-m/M 2 = 1.8; section between cell dm and vein M 2 greater than vein dm-m; vein dm-m slightly curved. Halter stem and knob beige, except the base of stem slightly light brown. Legs (Fig. 72). Coxae brown, gray pruinose; trochanters yellow; femora mostly brown, yellow on proximal half, with a row of long and fine yellow setae posterolaterally; tibiae yellow, hind tibia with erect setae medially; tarsomeres 1–4 yellow, 5 brown; pulvilli yellow. Abdomen (Figs 72–73, 77). Brown, tergite 1 gray pruinose, with four stout brown setae laterally; tergites 2–5 gray pruinose posterolaterally; tergites and sternites 6 and 7 as in Fig. 78. Syntergosternite 8 brown, brown pruinose, shorter than tergite 5, with membranous area large, dividing the syntergosternite 8 and reaching epandrium (Figs 77, 79). Terminalia (Figs 78–84). Epandrium light brown and surstyli yellow (Figs 79–80). Surstyli (Figs 80–82) subsymmetrical, equal in length to epandrium, completely setose; both surstyli with tips inward directed and inner margin with irregularly shaped lobes that converge apically; when seen in lateral view right surstylus strong and long, both surstyli with tips slightly downward directed (Figs 81–82). Apex of phallic guide stout, long, with distinct translucent lobes dorsally and ventrally, extreme tip acute and downward directed (Fig. 83). Ejaculatory apodeme funnel-shaped narrowed (Fig. 84). Phallus trifid, long, with apex of ejaculatory ducts coiled (Fig. 83).

FEMALE. Unknown.

Geographical distribution. Colombia (Caquetá) (Fig. 130).

Etymology. The specific epithet is nominated in honor of Paola Andrea Vargas Triviño. She is the wife of the first author, in gratitude to approximately 21 years of accompaniment, time in which she has been a support to travel this long path called ‘life’.

Habitat. The specimens were collected with Malaise traps at ground level, where the vegetation is composed of cloud Andean forests of the Eastern Piedmont of the Cordillera of the Southwest region of Colombia.

Taxonomic notes. Neocephalosphaera paolae sp. nov. runs to N. semispiralis Rafael & Rosa 1991 in the couplet 5 of the key presented by Souza & Ale-Rocha (2009). It differs from N. semispiralis by having the antenna with scape and pedicel dark brown (Fig. 74) (versus antenna with scape and pedicel dark yellow in N. semispiralis); scutellum brown (Figs 73, 75) (versus scutellum yellow); all coxae brown (versus fore and mid coxae yellow, hind coxa black); all trochanters yellow (Fig. 72) (versus fore and hind trochanters yellow, mid trochanter black); both surstyli with straight ventral margins when seen in lateral view (Figs 81–82) [versus both surstyli with two ventral lobes when seen in lateral view, figures 9–10, presented by Rafael & Rosa (1991)]; phallus trifid, long, with the apex of ejaculatory ducts coiled (Fig. 83) (versus phallus bifid, with ejaculatory ducts long and thin, apparently covered by a membrane with spines apically, in original description).
