Pino leg. “M4969 (1♂, IAvH) (photographed specimen) . Holotype with left wing mounted on microslide with Canada balsam. Right antenna and terminalia were placed in a microvial with glycerin, both pinned along the specimen. (hind legs lost).

Diagnosis. Coxae dark brown; trochanters yellow; femora yellow except mid femur with a small spot light brown dorsoapically; tibiae dark yellow. Abdomen dark brown, tergite 1 gray pruinose. Surstyli subsymmetrical totally covered in setae, stout basally, thin apically. Apex of phallic guide thickened at the base, thin apically, with a row of fine setae ventrally. Phallus trifid, stout, with ducts distinctly separated only in distal 1/3, somewhat coiled.

Postcranium black, brown pruinose dorsally, gray pruinose ventrally. Antenna ( Fig. 3 ) with scape dark brown, with one strong seta; pedicel dark brown with two long setae ventrally; postpedicel light yellow, with acuminate apex. LPP/WPP = 3.7. Labellum brown. Thorax ( Figs 1–2, 4 ). Postpronotal lobe brown. Scutum dark brown, yellow pruinose. Notopleuron concolorous with scutum, gray pruinose. Scutellum dark brown, yellow pruinose. Mesopleuron and mediotergite dark brown, gray pruinose. Wing ( Fig. 5 ). Length 7.5 mm. LW/MWW = 3.4; LTC/LFC = 1.3. Membrane light brown infuscated; third section costal shorter than the length of fourth; vein r-m located after the basal third of the upper section of the cell dm; vein M 2 short; dm-m/M 2 = 3.9; section between cell dm and vein M 2 greater than vein dm-m; vein dm-m slightly curved. Halter light brown. Legs ( Figs 1–2 ). Coxae dark brown; trochanters yellow; femora yellow except mid femur with small spot slightly brown dorsoapically; with a row of ventral spines and a row of long and fine yellow setae posterodorsally; tibiae dark yellow; tarsomeres 1–2 yellow, 3 and 5 slightly brown; pulvilli brown. Abdomen ( Figs 1–2, 6 ). Dark brown, tergite 1 with seven stout black setae laterally; tergites 1–5, brown pruinose laterally; tergites and sternites 6 and 7 as in Fig. 7 . Syntergosternite 8 brown, brown pruinose, shorter than tergite 5, with membranous area occupying less than half of syntergosternite 8 in dorsal view, not reaching the epandrium ( Fig. 8 ). Terminalia ( Figs 7–13 ). Epandrium brown, surstyli light brown ( Figs 8–9 ). Surstyli ( Figs 8–11 ) subsymmetrical, shorter than the length of epandrium, totally covered in setae, thickened at the base, thin apically, both surstyli with tips downward directed when seen in lateral view ( Figs 10–11 ). Apex of phallic guide stout basally, tapering apically, with a row of fine setae ventrally ( Fig. 12 ). Ejaculatory apodeme funnel-shaped ( Fig. 13 ). Phallus trifid, stout, with ducts distinctly separated only in distal 1/3, somewhat coiled ( Fig. 12 ).

FEMALE. Unknown.

Geographical distribution. Colombia (Cauca) ( Fig. 129 ).

Etymology. The specific epithet refers to the type locality, Munchique, National Natural Park, Colombia; probably the word Munchique comes from the indigenous language Chibcha which refers to the highest mountain, the mountain that holds many secrets.

Habitat. The specimen was collected with Malaise trap at ground level. The vegetation of the collection site corresponds to Andean forest of the Pacific region of Colombia.

Taxonomic notes. Cephalosphaera munchiquensis sp. nov. runs to C. guanacastensis Rafael & Menezes, 1999 in the couplet 11 of the key presented by Souza & Ale-Rocha (2009). It differs from C. guanacastensis in having all coxae dark brown (versus fore coxa yellow, mid and hind coxa brown in C. guanacastensis ); surstyli extensively covered by setae ( Figs 8–9 ) [versus surstyli bare dorsally, figure 2.F, presented by Souza & Ale-Rocha (2009)]; apex of phallic guide with a row of fine setae ventrally ( Fig. 12 ) [versus apex of phallic guide without a row of fine setae ventrally, figure 3.F, presented by Souza & Ale-Rocha (2009)]; phallus trifid, with ejaculatory ducts thin and distinctly separated only in distal 1/3, somewhat coiled ( Fig. 12 ) [versus phallus shortened stout and with two additional branches, giving the false impression of being five ejaculatory ducts, figure 3.F, presented by Souza & Ale-Rocha (2009)].
