DESCRIPTIONS AND RECORDS OF
NEOTROPICAL CONOPIDAE (DIPTERA)
Chicago, Illinois
The first part of this paper may be considered an ad- dendum to my work on New World Conops and allies (1955, Proc. U.S. Nat. Mus., 105, 155-187). A number of other apparently new forms have been seen; but I am awaiting more material, or the opportunity for a revisional study in the case of Zodion.
Diconops, subgen. nov.
Belonging to the genus Conops, but having a relatively long and narrow second abdominal segment. Second ab- dominal segment (female) dorsally, about three times as long as wide, sides parallel. Third segment about three- fourths as long as second, apex nearly two times as wide as base. One propleural bristle on the type species, none on the other species. Posterior margin of eye more con- cave than usual. Polished triangular area at posterior margin of eye nearly absent.
Type: Conops trichus, sp. nov.
This subgenus could be placed in Physoconops, as a group lacking the ocellar tubercle; but I consider the absence of the ocellar tubercle more characteristic of the genus Conops than the wide abdomen.
The male is as yet unknown.
Conops (Diconops) trichus, sp. nov.
Holotype 9 : Brazil: Nova Teutonia, Santa Catarina, Nov. 1952, F. Plaumann (author's collection). Vertex yellow, rounded anteriorly, black laterally. Front yellow with black "T" pattern. Face and upper grooves yellow. Lower face and grooves, and cheeks black. Facial grooves and orbital yellow pollinose. Occiput black. Anten-

na mainly black. Reddish yellow on third segment medially and on the first segment. First antenna1 segment four times as long as wide. Second segment nearly twice as long as first. Third segment about three-fourths as long as second. Arista three segmented, without lateral process on the second segment. Proboscis nearly twice as long as head; black, with yellow on apical ventral half. Thorax black. Gold pollinose faintly on dorsum, with distinct areas medial to the humeri, at base of wings, and at the scutellum. Pleura with distinct yellow pollinose stripe. Legs brownish yellow, partly black on coxae, apical tarsal segments, and most of claws. Wings yellowish hyaline, with brownish yellow pattern between first vein and third vein and vena spuria. Yellow in costal, sub- costal, and first basal cells. Calypters and halteres brown- ish yellow.
Abdomen black, yellow at fused junction of second and third segments. Apical margin of third segment, fourth, fifth, and sixth segments yellow pollinose, more distinct at distal margin. The hairs on the third to sixth segments more distinct than usual. Theca and genital segments shining black. Subapical genital segment mainly reddish. Theca as long as wide, and relatively thin. Size: 14% mm. (without antenna).
Paratype Q : same data, Dee. 1952.
Similar to the holotype. Posterior femora darker at basal half. Theca yellowish anteriorly.
Size: 15% mm.
This species keys to Physoconops gracilior (Camras, 1955, Proc. U. S. N. M., 105:186) but differs in the color of the vertex, facial grooves, cheeks, etc., in addition to the generic difference.
Conops (Diconops) geminatus, sp. nov.
Holotype Q : Peru: Monson Valley, Tingo Maria, Dec. 11, 1954, E. I. Schlinger and E. S. Ross (California Acad- emy of Sciences, San Francisco).
Vertex yellow, black on each side forming a velvety black triangular mark on each side of the front with the black "T" pattern of the front. Remainder of front, face,

19571 Carnras - Neotropical Conopidae 11 and upper facial grooves yellow. Cheeks and remainder of facial grooves black. Facial grooves, orbitals and inter- rupted post-vertical stripe gold pollinose. Occiput black. Antenna black. First antenna1 segment four times as long as wide. Second segment nearly two times as long as first. Third segment one and one-half times length of first. Arista three segmented. Lateral process on second segment in- distinct. Proboscis two times length of head, black with yellow on about distal ventral half.
Thorax black, with considerable gold pollen on dorsum covering it completely in certain views. In other views, there are three black stripes on the dorsum. A distinct gold pollinose pleural stripe is connected with the gold pollen of the dorsum. Legs yellow; blackish partly on coxae, base of hind femora, tarsi, except base of first tarsus, and claws. Wings hyaline, brownish pattern be- tween costa, and third vein and vena spura. The dark pattern in the first posterior cell is confined to less than the anterior half. Calypters dark yellow. Halteres bright lemon yellow, brown at base of stem.
Abdomen black, yellowish at junction of second and third segments. Gold pollinose at junction of first and second, second and third, and distal margins of remain- ing segments. Fifth, sixth, and base of seventh segments gold pollinose. Genital segments and theca dark reddish yellow. Theca as long as wide.
Size: 8% mm. (without antenna).
This species is similar to trichus but differs mainly in the color of the front, thorax, and wings. Although very different in appearance, they are probably geographical representatives. This species keys to Physoconops anten- natus (Camras, 1955, Proc. U. S. N. M. 105:186) but differs in generic and color characters. Physoconops parsonsi Camras
1955, Proc. U. S. Nat. Mus., 105, 171.
The types of this species had been erroneously placed in the U.S. National Museum Collection. P. J. Darlington, Jr., called our attention to this, and the types have been returned to the Museum of Comparative Zoology.

Physoconops pictus (Fabricius)
In the above mentioned paper (p. 166), the specimens from Havana, Cuba, and Manneville, Haiti, recorded from the U.S. National Museum, likewise belonged to the Museum of Comparative Zoology, and have been returned to that collection.
Physoconops (Shannonoconops) apicalis Camras 1955, Proc. U.S. Nat. Mus. 105, 172.
This distinctive form was described from a male from Mato Grosso, Brazil, and a female from Peru. Since then, I have received a male and a female from Nova Teutonia, Santa Catarina, Brazil, collected by F. Plaumann. Physoconops analis (Fabricius)
This name replaces Physoconops angustifrons (Willis- ton) in my review (1955, Proc. U.S. Nat. Mus. 105, 178). This important change of names has been made in my paper on New World Physocephala (1957, Ann. Ent. Soc. Am. 50, 217), but is repeated here as it is apt to be over- looked.
Zodion rossi, sp. nov.
Holotype 8 : Mexico: San Luis Potosi ; 40-50 miles N. W. C. del Maiz, Nov. 20, 1948, E. S. Ross (California Academy of Sciences, San Francisco).
Head pale yellow. Sides of upper front and vertex dark reddish. Center of ocellar tubercle black. Upper occiput blackish, lower occiput yellow. Antenna deep yellow, somewhat orange on third segment. First segment very short, shorter than wide. Third segment slightly longer than second. Arista black. Proboscis one and one-half times length of head; black, brownish at base. Palpi slightly longer than width of proboscis at base. Thorax yellow. Dorsum black with grayish yellow pol- linose submedian and sublateral lines. These lines joining posteriorly. The sublateral line is interrupted in the middle by the transverse suture. Humeri, light yellow. Scutel- lum deeper yellow, with a large tuft of black hairs on each side. Apical margin of scutellum slightly concave.

Camras - Neotropical Conopidae 13
Pleura mainly yellow. Sternopleura mainly black. Legs mainly yellow, dark reddish distally and dorsally on the femora. Tibiae more yellowish in the middle. Apical tarsi and apical half of claws black. Wings hyaline, yellow at base. First posterior cell long petiolate. Calypters light yellow. Halteres light yellow, dark reddish at base. Abdomen mainly deep yellow with paler yellow distal margins. Blackish red on first, basal two-thirds of second, about basal one-half of third, and basal centers of fourth and fifth segments.
Sides of second and third segments
yellow. Genital segments darker yellow.
Size: 5 mm.
Al1,otype : Same data.
Similiar to the holotype. Dorsal third of front and vertex rufous. Abdomen more predominantly dark rufous on most of the segments dorsally, yellow laterally and on distal margins. Median longitudinal yellow band on fifth, sixth and seventh segments. Genital segments black. Theca apparently as long as wide.
Size: 5% mm.
Paratype 8 : same data. (Retained in author's collec- tion).
Similiar to the holotype, but somewhat more rufous on vertex and abdomen. Size: 4% mm.
This very distinctive form differs structurally from the other species of Zodion in the scutellum and wing vena- tion, and could be placed in a separate subgenus. Scatoccemyia, gen. nov.
Similar to Occemyia, but having a markedly thickened anterior cross vein, shorter, thicker antenna, more quadrate shaped head, a fronto-facial black mark, more prominant rows of bristles on ventral surface of femora, more pol- hose (less shiny black) coloration, and more hairy ap- pearance.
Type: Scatoccemyia plaumanni, sp. nov.
This genus resembles a Scatophagid. Since the genus Occemyia has not been found in South America as yet, this genus may be replacing it on that continent.

This species keys to Curran's couplet 7, differing from the alternatives in the female by having the apical seg- ment of the ovipositor black haired proximally and apically, and white haired on about the middle third. In the male, this species differs from the alternatives at couplet 7, by having the basal three-fifths of the posterior tibia entirely black.
Named after H. de Souza Lopes in recognition of his fine work on this genus.
