( Figs. 107–111View FIGURES 107 – 111, 119View FIGURES 116 – 119, 145View FIGURES 144 – 145)

Diagnosis. Male: only species of Neotropical Forcipomyia (Metaforcipomyia)  with a tarsal ratio of 2.11–2.57, wing with a dark patch on its anterior margin and at the apices of M 2, CuA 1 and CuA 2, hind leg with tarsomeres 1–2 brown, contrasting with pale tarsomeres 3–5, parameres present and the aedeagus bearing stout, laterally directed, subapical, heavily sclerotized projections. Female: unknown.

Description. Male. Head. Brown. Eyes abutting medially for length of two-three ommatidia. Antenna ( Fig. 107View FIGURES 107 – 111) pale brown with plume setae well-developed, flagellomere 10 1.30–1.66 (1.42, n = 12) X longer than flagellomere 11, flagellomeres 10–13 elongate; flagellomere 13 with apical nipple slightly constricted basally; AR 0.99–1.12 (1.05, n = 12). Palpus ( Fig. 108View FIGURES 107 – 111) with segment 3 short, slightly swollen proximally, with shallow sensory pit opening at midlength; PR 1.70 –2.00 (1.87, n = 12). Labrum tapering apically.

Thorax. Brown; scutellum with 6 strong setae, and several minor ones. Legs uniformly pale brown; apex of hind tibia with 4–5 spines; tarsomeres with pectinate scales; tarsomere 1 of foreleg with row of dozen spine-like bristles, tarsomere 1 of hind leg with two rows of thick setae, tarsomeres 3–5 slightly paler; foreleg TR 2.38 –3.00 (2.81, n = 12), midleg TR 2.10–2.43 (2.26, n = 10), hind leg TR 2.11–2.57 (2.31, n = 12); claws curved, moderately stout. Wing ( Figs. 109View FIGURES 107 – 111, 119View FIGURES 116 – 119) with pattern of pigmented membrane, with dark patch on its anterior margin and at apices of M 2, CuA 1 and CuA 2; intercalary vein not visible; radial cells closed; fork of cubitus situated proximad to level of apex of costa; wing length 0.66–1.02 (0.80, n = 12) mm; breadth 0.22–0.34 (0.27, n = 12) mm; CR 0.42–0.45 (0.44, n = 12). Halter whitish.

Abdomen. Tergites uniformly brown. Genitalia ( Fig. 110View FIGURES 107 – 111): Dark brown except gonostyli pale. Tergite 9 short, extending to 1 / 5 length of gonocoxite; posterior margin broadly rounded; cercus lobe-like, slightly produced beyond midlength of gonocoxite; sternite 9 broad, posterior margin nearly straight. Gonocoxite moderately stout, two X longer than greatest breadth; gonostylus 0.9 length of gonocoxite, nearly straight, narrowed to tip. Parameres represented by a pointed, posteromesally directed projection, gonocoxal apodemes deeply concave. Aedeagus ( Fig. 111View FIGURES 107 – 111) shield-shaped, with subapical, heavily sclerotized projections directed laterally, apex concave; basal arch extending to 0.25 of total length.

Female. Unknown.

Distribution. This species is known only from Costa Rica, from 100–2250 meters ( Fig. 145View FIGURES 144 – 145).

Taxonomic discussion. The male of this species is readily distinguished from that of other Neotropical species of the subgenus except F. grandiseta  by the presence of an aedeagus with stout, subapical, heavily sclerotized, laterally directed projections. However, the male of F. grandiseta  has thick, reinforced setae on foretarsomere 2.

Derivation of specific epithet. This species is named after our good friend and colleague María Marcela Ronderos, from the Museo de La Plata, Argentina, who has contributed so much to our understanding of both adult and immature Neotropical Ceratopogonidae  .
