Abstract
The first part of a Conopid faunal review for Costa Rica presents data for 25 species from the Conopinae (tribes Tropidomyiini and Conopini). Two hundred and eighty-five specimens have been examined and identified. Physocephala herrerai spec. nov. and Physoconops zumbadoi spec. nov. are new to science. Sixteen species are reported the first time for
the country. We introduce the following taxonomic changes: Physoconops (Gyroconops) ocellatus (Giglio-Tos, 1892) is
a valid species [status rev.]; Physoconops rufipennis (Macquart, 1844) belongs to the subgenus Pachyconops Camras,
1955 [status rev.]; Physoconops gracilianus Camras, 1955 is a junior synonym of Physoconops pallifrons (Coquillett,
1904) [syn. nov.]. Keys for the species of the genera Physocephala Schiner, 1861 and Physoconops Szilady, 1926 are
presented. Most species are illustrated with photo plates.
Key words: Diptera, Conopidae, Conopinae, Conopini, Tropidomyiini, fauna, Costa Rica. spec. nov., syn. nov., status

Introduction
Kröber (1937) was the first to compile a species list of Costa Rica´s Conopidae. Since then, some species have
been published as new for the country and many new specimens have been collected but there hasn’t been a
second attempt to summarise the knowledge. The aim of this work is to update Kröber´s list by collecting the
newly published faunistic data and by adding new records of Conopidae. To make the work easier for research
in the future we add determination keys for the species and illustrate most of the species with photographs.
This is the first of three parts of this project. We present the Conopinae now. The second part will deal with
Myopinae and the third part with Stylogastrinae.
Materials & methods
For determination to subgenus, the key of Thompson et al. (in press) is used. A key is presented for each subgenus or genus with more than one species recorded in Costa Rica. Synonyms used in older literature follow
Thompson et al. (in press). Literature citing faunistic records of Conopidae from Costa Rica is listed for each
species. The genera, subgenera and species are presented in alphabetical order. Unless otherwise stated, the
material has been determined by using the original description, using the keys of Camras (1955, 1957a, 1996)
and comparing the material with specimens determined by Camras. Material was used from the following collections:

The characters given by Camras (1957a, 1996) to separate Physocephala bipunctata and Physocephala
inhabilis cannot be used and we have seen specimens determined by Camras that don’t fit the characters given
in his keys. The characters in our key are suitable to distinguish two closely related forms occurring in Costa
Rica but don't work for material from other Neotropical regions. Further studies are required to discover if
Physocephala bipunctata and Physocephala inhabilis are conspecific.

Some of the female specimens listed here have been determined by Camras as Physocephala aurifrons
(Walker, 1849). Using the information of Camras (1996) these species can be separated by the pubescence and
the form of the male abdomen. We cannot see any differences in the material available and therefore the status
of aurifrons as well as its occurrence in Costa Rica remains doubtful.

Description of the holotype (female)
Head 3.5 mm high. Eye brown, facets a little bit larger in the centre near the face. Hind margin of eye
slightly concave in the middle. Antenna completely orange, with black bristles at the top of the scape and
mainly dorsally on the pedicel. Ventral flagellum membrane-like. Second segment of the style as long as the
third segment, the third segment slightly blackish at the tip. Head mainly yellow, gena black with clear yellow
centre, upper parts of frons black, vertex and ptilinal fissure light brown. Obvious pubescence only bordering
the eyes with the exception of the frons, pubescence golden at the postcranium and grey at the gena. A less
obvious pubescence can be seen when looking at a suitable angle at the gena and the postcranium. Vertex and
postcranium (with the exception of the postgena) with long black hairs. Proboscis orange.
Thorax black. Only a few hard-to-find black hairs at the dorsal posterior part of the katepisternum and the
whole mesoscutum with scutellum and postpronotum covered with short black hairs. Thorax completely covered with a less obvious grey pubescence, the dorsal posterior part of the katepisternum with more obvious silver pubescence.
Legs orange brown with the exception of the hind femur, the apical part of the hind tibia and the top of the
claws that are all blackish. Legs covered with black hairs with these exceptions: anteroventral side of fore
tibia with short dense golden hairs, fore and middle tibia posterior at the apical part with dense golden pubescence, hind tibia apically covered with dense golden hairs, ventral and posterior part of the femora without
hairs. Coxa densely silver to golden pubescent, femora less obvious silver dusted.
Length of wing 12 mm (measured from the top of the wing to the tegula). Wing completely covered with
microtrichia with the exception of the alula, the anal lobe and the basal part of the posterior cubital cell cup.
Venation and colouration as shown on figure 21. Haltere yellow with a black basis and a black apex; 5–6 black
bristles at the stem. Calypters yellow brown with a slightly darker border and small golden hairs on the thicker
border.
Abdomen completely black to dark brown; covered with silver grey pubescence with the exception of
tergite 5, syntergite 6, and partly the lateral margins of tergite 2. Abdomen completely covered with black
hairs that are smaller and less dense at the base of tergite 1. Form of the tergites as shown in figures 16 and 18.
The elongated syntergite 6 and the rounded tergite 5 are distinctive. Theca very broad and completely covered
with black bristles that are arranged in small regular lines with about 6–12 bristles in each line.
Etymology
The species is named after Alvaro Herrera (INBIO; Santo Domingo, Heredia) who was very helpful when
we visited the INBIO collection in Costa Rica.
Diagnosis
The first couplet in Camras (1996) doesn’t work when identifying this species because the frons is about
half black and yellow. Following couplet 1 "Frons mainly or entirely dark" will lead to couplet 14 with the
species Physocephala carbonaria and Physocephala aurifrons. The distinction of Physocephala herrerai and
Physocephala carbonaria is given in our key. As stated above, the status of Physocephala aurifrons remains
doubtful and cannot be separated. Following couplet 1' "Frons mainly or entirely pale" will lead to couplet 30
where both species offered don´t fit Physocephala herrerai (i.e. it is not a rufous species and does not have a
pollinose pleural stripe).

Literature: Kröber (1937, as "Physocephala testacea v. d. Wulp").
There is no known Costa Rican material of this species available and we can only accept the record of
Kröber (l. c.) who knew the species from several locations in the Neotropical region.

Physoconops (Aconops) longistylus (Kröber)
Conops longistylus Kröber 1916: 149.
Literature: Kröber (1937, as "Conops longistylus Kröb.").
The four nominal species of Aconops belong to three valid species. These three species of the subgenus
Aconops cannot be determined using existing keys. The characters used by Camras (1955) are not suitable to
distinguish the species. We haven't seen any specimens of this subgenus from Costa Rica and therefore the
occurrence of Physoconops longistylus in Costa Rica remains questionable, because it is possible that Kröber
confused his "Conops longistylus" with other similar species.

The identity of this species is based on the original description. The black tibiae are yellow at the base, fitting the Giglio-Tos description of Gyroconops occellatus: "tibiis omnibus medietate basali flavis".
Thompson et al. (in press) list Physoconops ocellatus as a junior synonym of Physoconops parvus. Based
on the characters given in the key, Physoconops ocellatus is a distinct species and should be accepted as valid
(status rev.).

Description of the holotype (female)
Head 2.2 mm high. Eye brown, facets a little bit larger in the centre near the face. Prominent triangular
mark on the posterior margin of the eye. Ocelli orange; ocellar triangle large, reaching about the middle of the
frons. Antenna black with lighter orange brown areas ventral at the scape and more obvious basally at the ventral side of the flagellum. Form of the antenna as shown in figures 64 and 66: Flagellum broader and longer
than pedicel. Black bristles apical and basoventral at the scape and dorsal and ventral at the pedicel. Frons
black; face mainly yellow with slightly darkened areas in the antennal groove and at the gena; postcranium
black. Face, frons and postcranium completely silver pubescent with the exception of the glabrous border of
the antennal groove at the ptilinal fissure. Vertex and postcranium with black hairs. Proboscis black to dark
brown.
Thorax black. Two black bristles at the dorsal posterior part of the katepisternum and one black bristle
ventrally at the propleuron. Mesoscutum with scattered black hairs, two obvious submedial lines of black
hairs, several notopleural bristles, one pair of supraalar bristles, two pairs of postalar bristles, one pair of prescutellar bristles, two pairs of scutellar bristles and several bristles on the postpronotum. Thorax completely
covered with a less obvious grey pubescence, there are no areas with obvious pubescence.

Legs black with orange-brown bases of tibia and orange yellow pulvilli and empodia. Legs covered with
black hairs with these exceptions: posterior side of femora, anterior side of middle and hind femur, the posterior apical part of the fore and middle tibia that is densely covered with silver pubescence, the posterior apical
part of the hind tibia that is covered with dense short black bristles. Coxae densely silver dusted, femora less
obvious silver dusted. Each trochanter with one black bristles. Tarsi as figure 67.
Wing length 6.8 mm (measured from the top of the wing to the tegula). Wing mainly covered with microtrichia with the exception of the alula, the anal lobe and the basal part of the posterior cubital cell cup, the basal
radial cell br, the basal medial cell bm and the basal part of the discal medial cell dm. Venation and colouration
as shown in figure 69. Haltere yellow with a black base; several black bristles at the knob of haltere. Calypter
brown with a white border at the upper calypter.
Abdomen mainly black, tergite 2 and tergite 3 brownish black, with an obvious small yellow band at the
border of tergites 2 and 3. Tergites 1 and 2 with a less obvious grey pubescence, the remaining abdomen with
denser golden pubescence that is most obvious at the hind margin of tergites 3 and 4 and on the whole of tergites 5 and 6, the apical part of tergite 7 and tip of the abdomen shiny. Abdomen completely covered with black
hairs that are smaller and less dense at the base of tergite 1. Tergites as shown in figures 63 and 68. Theca
quite small as shown in figure 68.
Description of the male
One of the three males has a completely black face. Other than this, males only differ from females in the
typical differences in the postabdomen.
Etymology
The species is named after Manuel Zumbado (INBIO; Santo Domingo, Heredia) who facilitated our work
when we visited the INBIO collection in Costa Rica.
Diagnosis
The species is very distinctive. Because of the long pedicel it looks like a species of the Physoconops subgenus Pachyconops. The key of Camras (1955) places it in this subgenus. However, the small frons, two pairs
of scutellar bristles, one pair of prescutellar bristles, two submedial rows of bristles and the prominent triangular mark on the posterior margin of the eye are characters of Physoconops s. str. This combination of characters is not known from any other Physoconops. The species resembles Physoconops nigromarginatus, and one
paratype of P. zumbadoi was determined as nigromarginatus by Camras. The distinction of the two species is
given in the key above.

Camras (1955) separates Physoconops gracilianus from Physoconops pallifrons only by the colouration
of the cheek (Coquillett, 1904). The material from Costa Rica shows that this character is variable and not
suitable to distinguish the two species. Therefore we propose that Physoconops (Pachyconops) gracilianus
Camras, 1955 is a junior synonym of Physoconops pallifrons (Coquillett, 1904) [syn. nov.].

Physoconops (Pachyconops) rufipennis (Macquart) [comb. nov.]
Conops rufipennis Macquart 1844: 167.
Literature: Camras (1955, record from Costa Rica marked with a "?"); Kröber (1937).
The type of Conops rufipennis Macquart, 1844 was examined. The specimen does not fit in the concept of
the subgenus Kroeberoconops Camras, 1955 because the flagellum is longer than the pedicel. The specimen
belongs in the subgenus Pachyconops (comb. nov.).
We haven’t seen Costa Rican specimens of this species so the occurrence of Physoconops rufipennis in
Costa Rica remains doubtful.
The subgenus Kroeberoconops now only includes two species – Physoconops (Kroeberoconops) hermanni (Kröber, 1915) and Physoconops (Kroeberoconops) argentinus Camras, 2004. The distribution of this
subgenus is restricted to Argentina and it is unlikely that Kroeberoconops occurs in Costa Rica.
