description: Brazitrypa maroniensis (Chopard, 1930) n. comb.
(Fig. 17)
Tafalisca maroniensis Chopard, 1930: 530.
TYPE LOCALITY. — French Guiana, Maroni.
TYPE MATERIAL. — Holotype. French Guiana • ♀; Maroni, Guyane; MNHN-EO-ENSIF6596; MNHN.
EMENDED DIAGNOSIS. — This species is separated from the other species of Brazitrypa by the following characters: HWs as long as FWs in dorsal view. TIII subapical spurs with two spines between each inner and outer pair of successive spurs, the first one the longest; four spines above inner and outer subapical spurs. Female genitalia: copulatory straight in lateral view; anterior margin convex in dorsal view and pointed in ventral view.
REDESCRIPTION
General morphology
Body. Medium size, general coloration medium to light brown, body covered by bristles, except FWs and HWs (Fig. 17 A-C).
Head. Occiput and vertex with bristles, medium brown. Fastigium as long as wide, pubescent, medium brown. Frons light brown, with dark brown band under the eyes (Fig. 17D). Eyes longer than wide in lateral view, ommatids black (Fig. 17B). Antennal scape almost as long as wide, light brown; antennomeres medium brown. Gena light brown in frontal and lateral views. Mandibles medium brown, with dorsal maculae dark brown in frontal view. Epistomal suture light brown; clypeus medium brown; labrum medium brown, darker ventrally (Fig. 17D).
Pronotum. DD longer than wide, pubescent, medium to dark brown, DD cephalic margin slightly concave with yellowish bristles; caudal margin convex, with yellowish bristles (Fig. 17A). LL ventro-cephalic angle rounded, light brown; ventro-caudal angle gradually ascendant, medium brown in lateral view (Fig. 17B).
Wings. FWs covering entire abdomen; FWs somewhat translucent, light brown, with veins medium brown (Fig. 17A). HWs as long as FWs in dorsal and lateral views.
Legs. Legs I and II with yellowish bristles. FI and FII light brown. TI and TII light brown. TI with three apical spurs: two ventral same-sized; one dorsal, inner, longer than ventral ones. FIII longer than TIII, light brown, apex dark brown (Fig. 17B). TIII dark brown, with yellowish bristles. TIII subapical spurs 5/4, with two spines between them, the first one the longest; four spines above inner and outer subapical spurs. TIII apical spurs 3/3, longer on inner side; inner apical spurs: dorsal longest (iad), median shorter than dorsal (iam), ventral smallest (iav) (iad>iam>iav); outer apical spurs: median longest (oam), dorsal slightly shorter (oad), ventral almost same size of dorsal (oav) (oam>oad>oav). TIII subapical spurs and spines and apical spurs dark brown (Fig. 17A, B). Basitarsus dorsal spines 3/2, apical spine the longest; inner and outer apical spurs shorter than basitarsus. Basitarsus dark brown.
Abdomen. Tergites slightly pubescent, medium to dark brown. Cerci pubescent, medium brown, with light brown setae.
Female
Morphology. Subgenital plate wider than long, posterior margin slightly concave; medium to dark brown, covered by bristles (Fig. 17C). Ovipositor upcurved, dark brown (Fig. 17B).
Female genitalia (Fig. 17 E-G). Copulatory papilla straight in lateral view, without ventral aperture; posterior margin acuminated. Anterior margin convex in dorsal view and pointed in ventral view.
Male
Unknown.
Measurements (mm)
Female (n = 1, holotype). HW, 4; IOD, 2; PL, 4.8; PW, 4.2; FWL, 15; FWW, 3.6; HWL, 15; LFIII, 11.6; WFIII, 3.4; LTIII, 8; LBtarsIII, 2; OL, 11.2.
REMARKS
This species has the following characters that are characteristics to Brazitrypa and differ from Tafalisca: ocelli absent, absence of small protuberances on dorsal side of fore and mid tibias, ovipositor apex pointed, copulatory papilla triangular and flattened dorso-ventrally. The male of Brazitrypa maroniensis n. comb. is unknown, however, the features above mentioned are enough to transfer this species to Brazitrypa.
