(Figs. 92–96, 117, 144)
Diagnosis. Male: only species of Neotropical Forcipomyia (Metaforcipomyia) with an aedeagus with a short apicomedial prong, and parameres present. Female: unknown.
Description. Male. Head. Brown. Eyes abutting medially for length of two-three ommatidia. Antenna (Fig. 92) pale brown with plume setae well developed, flagellomere 10 1.43–1.63 (1.50, n = 4) X longer than flagellomere 11, flagellomeres 10–13 elongate; flagellomere 13 with apical nipple not constricted basally; AR 1.04–1.08 (1.06, n = 4). Palpus (Fig. 93) brown; segment 3 slender, with shallow sensory pit opening at midlength; PR 2.30–2.89 (2.63, n = 5). Labrum tapering apically.
Thorax. Uniformly brown. Legs uniformly brown; apex of hind tibia with 4 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 2.75–3.00 (2.83, n = 5), midleg TR 1.89–2.22 (2.07, n = 5), hind leg TR 2.00–2.33 (2.14, n = 5); claws curved, moderately stout. Wing (Figs. 94, 117) with pattern of pigmented membrane, with dark patch on its anterior margin and at the apices of M2, CuA1 and CuA2; distribution of macrotrichia showing two distinct light spots in r3, one behind of second radial cell, one subapical, faint distal light spots in m1, m2, distinct light spots in cua1 and anal cell; M2 only visible at wing margin; first radial cell obliterated; second radial cell well-formed; fork of cubitus situated slightly proximad to level of end of costa; wing length 0.80–0.92 (0.85, n = 5) mm; breadth 0.26–0.32 (0.28, n = 5) mm; CR 0.44–0.46 (0.45, n = 5). Halter whitish.
Abdomen. Tergites brown. Genitalia (Fig. 95): Dark brown except gonostyli pale. Tergite 9 short, extending to 2/5 the length of gonocoxite; posterior margin broadly rounded; cercus lobe-like, slightly produced beyond midlength of gonocoxite; sternite 9 broad, posterior margin nearly straight. Gonocoxite stout, 2.15 X longer than greatest breadth; gonostylus 0.75 length of gonocoxite, almost straight, tip pointed. Parameres represented by a pointed, posteromesally directed projection, gonocoxal apodemes slightly concave. Aedeagus (Fig. 96) stout, lateral margins sclerotized, slightly narrowed to broad, rounded tip, apex with short prong; basal arch extending to 1/4 of total length; lateral arms extending laterally.
Female. Unknown.
Distribution. This species is known only from the lowlands of western Costa Rica, from 100–750 meters (Fig. 144).
Taxonomic discussion. The male of this species is readily distinguished from other Neotropical species of the subgenus by the shape of the apex of aedeagus which bears a short prong.
Type material. Holotype male on microscope slide, labeled “ HOLOTYPE Forcipomyia (Metaforcipomyia) germinata Spinelli, Marino and Borkent, Costa Rica, 2 km NE Tárcoles, 17-XII-1993, Borkent, CD 1710” (CNCI). Paratypes, 4 males as follows: Costa Rica, Puntarenas prov., Pto. Osa, Est. Agujas, 300 m, 15/VII-15/VIII-1999, J. A. Azofeifa, CD 5089, 1 male (MLPA). Costa Rica, Puntarenas prov., Golfito, Corcovado NP, Est. Agujas, Los Charcos, 600 m, 15-V / 15-VI-1999, J. Azofeifa, Malaise tp., CD 5176, 1 male (INBC). Same data except C. Rincón, 745 m, 15-VI / 15-VII-1999, CD 5354, 1 male (INBC). Costa Rica, San José prov., San Isidro, 740 m, 17-XI- 1999, A. Picado, CD 5048, 1 male (INBC).
Derivation of specific epithet. The name germinata – germen (bud, sprout) refers to the small, apical protrusion at the apex of the aedeagus.
