Metrichia camposnovos sp nov.
( Figs 3A View FIGURE 3 –4D)
Diagnosis. This new species can be assigned to the Metrichia aberrans Group Flint (1972) due to absence of internal pouches in abdominal segments. Metrichia camposnovos sp nov. resembles Metrichia aberrans Flint 1972 due to the shapes of sternum IX, the dorsal hook, and the inferior appendages, in lateral view. The new species can be distinguished from M. aberrans by the inferior appendages, in lateral view, subtrapezoidal, with their apicoventral margins nearly straight in the new species (apicoventral margins sinuous in M. aberrans ). Additionally, the phallus of the new species has a median process that is absent in M. aberrans . For further information and illustrations of M. aberrans , see Flint (1972).
Description. Adult male. Forewing length 2.1 mm (Holotype), ranging from 1.9–2.1 mm (n = 2). General color (in alcohol) dark brown. Head without modifications, with three ocelli; dorsally with two pairs of setal warts; ocellar pair appressed on midline, each subtriangular; occipital pair large, ellipsoid. Antennae unmodified, 18- articulated. Maxillary palpi each 5-articulated; labial palpi 3-articulated. Mesoscutellum broadly subtriangular and with transverse suture. Wing venation reduced in both wings. Tibial spur formula 1-3-4. Abdominal segments without modifications. Sternum VII with ventromesal process. Segment VIII shorter ventrally than dorsally.
Male genitalia. Segment IX membranous dorsally; in lateral view ( Fig. 3A View FIGURE 3 ) tapering anteriorly; in ventral view ( Fig. 3B View FIGURE 3 ), ogival and apically round anteriorly, recessed and irregular posteriorly; in dorsal view ( Fig. 3C View FIGURE 3 ), with round posterior margin. Inferior appendages covered by long setae; in lateral view ( Fig. 3A View FIGURE 3 ), subtrapezoidal, with dorsal, ventral, and apicoventral margins nearly straight, apicodorsal apex acute; in ventral and dorsal views ( Figs 3B, 3C View FIGURE 3 ), subtrapezoidal, with acute apicomesal and apicodorsal apices. Dorsal hook about as long as inferior appendages ( Fig. 3B View FIGURE 3 ); in lateral view ( Fig. 3A View FIGURE 3 ), downturned apically. Preanal appendages, in lateral and dorsal views ( Figs 3A, 3C View FIGURE 3 ), round and bearing very long setae. Subgenital plate apparently absent. Tergum X membranous and ogival ( Fig. 3C View FIGURE 3 ). Phallus tubular, elongate, slender, constricted near mid-length, with median process arising in constriction; with two curved subapical spines arising at nearly same level, one curved to left, other curved to right; apex truncate and membranous; ejaculatory duct sinuous, sclerotized, and not protruding apically ( Fig. 3D View FIGURE 3 ).
