INSECTA MUNDI, Vol. 13, No. 3-4, September-December, 1999 235 A new species of Cydistomyia (Diptera, Tabanidae) from Papua New Guinea James T. Goodwin Jarvis Christian College P.O.Box 1470 Hawkins, TX 75765-9989 Abstract. A new species, Cydistotnyia katnialielzsis, is  described from specimens collected in the  Kamiali Wildlife Management Area of  Morobe Province, Papua New Guinea. Introduction Mackerras (1964) included the tabanid fauna of Papua New Guinea in his coverage of the fauna of the Papuan (New Guinea) Subregion, an  area en- compassing the entire island of New Guinea as well a s  the smaller islands lying approximately between 0" and 12" S. latitude and 129" and 155". longitude. Additional information on the tabanids of the subre- gion appeared in two shorter papers (Mackerras 1971, 1972). A few subsequent papers covering the fauna of other parts of the Australasian and Ocean- ian Regions were found, and some included taxo- nomic changes affecting generic and subgeneric names of species found in the Papuan Subregion. These changes were summarized by Daniels (1989) who provided the most current faunal list of Taban- idae for the Australasian and Oceanian Regions. In  addition, Chainey (1988), which was not mentioned by Daniels (1989), included the description on a new species, Lilaea (Cyanolilaea) ismayi Chainey, from Papua New Guinea as  well a s  revisionary changes affecting names of other species from the Subre- gion. The new species described below is named for the Kamiali Wildlife Management Area in Morobe Province, Papua New Guinea. Commonly referred to as just Kamiali, the wildlife management area, has a marine and land surface area of a t  least 342 km"possib1y as  much as 434 km 2, within the boundaries of the Lababia Village land area. It is located approximately 60 lcm SSE down the Huon Gulf coast from the provincial capitol of Lae. The land area of 269 km2 is covered by predominantly pristine coastal rain forest on the surfaces of moun- tains and ridges ranging from sea level to a little above 2,000 m. The people of Lababia and the smaller villages of the Kamiali have made the deci- sion to set aside most of the area as a wildlife management area rather than sell timber rights to private companies. They hope in this way not only to conserve their forest holdings for their descen- dants but also to derive income from activities for which the Kamiali will be the attracting force. Activities planned include hosting training work- shops, supporting visiting scientists interested in studies of the biota of the area, and ecotourism. They have been assisted in these endeavors by the Village Development Trust (VDT), a non-govern- mental organization with offices in Lae. Guest hous- ing, dining facilities, and a training center have been constructed, and the first training courses were carried out in late 1997. In addition, in early 1997, VDT entered into an  agreement with the Environmental Research and Management Centre (ERMC) of the Papua New Guinea University of Technology in Lae to initiate an  inventory of the biodiversity of the Kamiali and to train some of the villagers to work with visiting scientists and to serve as guides. I was fortunate to be one of the scientists asked to participate in these studies. I was warmly received by the villagers and received extremely good support during all my vis- its, an  extremely important parameter for field research in Papua New Guinea. Unlike most other countries of the world, close to 95% of the land resources of the country are tribally held, but own- ership is never a clear matter. Obtaining permis- sion to collect in an  area is difficult a t  best, and security for oneself and one's equipment is far from guaranteed. As a consequence, being not only invit- ed to collect in the Kamiali, but also being given tremendous support while collecting, will always be rememberedwith pleasure. I t  is for this reason that  I have elected to name the species described herein in honor of the area, its history, and its people. I also recommend to others interested in the biota of Papua New Guinea that  they consider the Kamiali as an  area for investigation. Information can be obtained and/or arrangements made by con- 236 Volume 13, No. 3-4, September-December,  1999, INSECTA MUNDI Figure  1.

Cydistomyia kamialiensis n e w  species Description: Holotype female: A vivid golden-yel- low and black species with emerald green eyes and wings intensely and darkly infuscated except along posterior border. Length 11 mm; wing 10.5 mm long. Head: Eyes unicolorous dark, emerald green; frons (Figure 1) nearly parallel-sided, golden yellow pollinose with scattered blackish brown hairs throughout except for the large shining callus; cal- lus narrowly separated from eyes by pollinose re- gion, extending from subcallus to just above mid- point of frons, widest basally and progressively narrowed dorsally over basal two-thirds and then sharply constricted to pointed apex; callus dark blackish brown over upper three-fourths to four- fifths, orange-brown below; subcallus bare and shin- ing orange-brown, a little lighter in color than basal area of callus; parafacials and face golden yellow pollinose with rather sparse black and golden hairs, the black hairs more prevalent near eyes; antennae (Figure 2) orange-brown, thinly pollinose, scape and pedicel with moderately abundant short black hairs, Figures 2-3.

Diagram of palp of female holotype. third segment with a tuft of short black hairs on tooth and scattered black hairs on annuli; dorsal excision of plate rather shallow; palpi (Figure 3) sub-shiny, black, with dense black hair, hairs shorter on second versus basal segment; second palpal segment about equal in length to entire antenna. Thorax: Ground color of thoracic dorsum, in- cluding scutellum, shiny blackish-brown, but dark color entirely obscured by dense golden yellow pol- linosity (NOTE: ground color based on color of shiny non-pollinose areas in middle and a t  tip of scutel- lum due to rubbing in the killjar; entire dorsum of thorax and scutellum of type pollinose a t  time of collection); dorsum with a mixture of scattered, elongate golden and black hairs; upper half of pleu- ra  concolorous with dorsum, with rather dense tufts of long golden hairs below wing bases anteriorly and posteriorly; lower half of pleura and venter shiny blackish-brown; legs shiny blackish-brown with black hairs, the only slightly paler areas being the joints a t  the proximal and distal ends of the tibiae and the pulvilli. Wing (Figure 4; wing of paratype used so as  to leave holotype intact ) intensely infus- cated dark brown to blackish throughout except for clear posterior zone originating in cell r, where it occupies most of the apical half of the cell (but not reaching anteriorly to vein R,) and extends towards body in a progressively narrowing strip through cua, and then abruptly expands to include much of the anal area. Abdomen: Ground color dorsally primarily or- ange brown; first tergite entirely orange brown but very slightly darkened posterolaterally; orange brown area progressively narrower on tergites 11-V and confined to a small median basal area on tergite VI; remaining areas of dorsum shiny dark brown to INSECTA MUNDI, Vol. 13, No. 3-4, September-December, 1999 237 black; hairs mostly dark regardless of ground color; laterally on the first sternite just behind the halter- es, there is a conspicuous golden-yellow pollinose and golden haired extension from the similarly colored band occupying the upper half of the pleura; ground color ventrally a brighter orange brown than dorsally, occupying the middle halves of ster- nites I-IV, middle third of sternite V, and less of sternite VI; remaining areas shiny dark brown to black; hairs generally concolorous with ground col- or. Variation: Three female specimens were collected. Observed variations as  follows: one paratype is approximately 0.5 mm shorter than the holotype, the other less than 0.5 mm 1onger;the orange brown of the venter of the abdomen of the holotype is more sharply delimited by the dark lateral areas than in the paratypes; otherwise all three specimens are similar.

Goodwin (1) and Mountain rain forest, 50-250 m.,l-3 km W of Laba- bia, Morobe Pr., Papua New Guinea, 12-14 VI 1997, J. T. Goodwin (1). Identification: Although Mackerras (1971, 1972) include descriptions of species of Cydistomyia Tay- lor, none is closely similar to the species described here. Consequently, Mackerras (1964) includes the most recent key to the fauna of the New Guinea Subregion. In  the initial key to Cydistomyia in Mackerras (1964, p. 112), the genus is separated into three species groups. One, the basifasciata group, has  been returned to generic status as  the genus Chasmia Enderlein (Daniels 1989). Of the two remaining species groups, C. kamialiensis would key to the albithorax group. In the key to the albithoraxgroup (p. 131), i t  would key to C. imitans Oldroyd in couplet 1. In the description of C. inzitans Oldroyd provid- ed by Mackerras (1964, p. 136), he makes reference to a New Caledonian species, C. colasbelcouri Mack- erras and Rageau, noting that  C. imitans is distin- Figure 4.

Examination of specimens of both C. ilnitans and C. colasbelcouri confirmed these differ- ences. Cydistomyia kalnialiensis differs from C. inzi- tans and C. colasbelcouri as follows: the pleura are densely golden pollinose and concolorous with the mesonotum, there are distinct tufts of long golden hairs below the wing bases anteriorly and posterior- ly, and the lateral margins of tergite one are densely golden pillinose and concolorous with the pleura, whereas, in C. imitans and C. colasbelcouri, the pleura are dark brown and contrasting with the golden colored mesonotum, the hair tufts below the wing bases are predominantly brownish, and the lateral areas of the first tergite are dark brown.

Abstract. A new species, Cydistotnyia katnialielzsis, is  described from specimens collected in the  Kamiali 
Wildlife Management Area of  Morobe Province, Papua New Guinea. 
Introduction 
Mackerras (1964) included the tabanid fauna of 
Papua New Guinea in his coverage of the fauna of 
the Papuan (New Guinea) Subregion, an  area en- 
compassing the entire island of New Guinea as well 
a s  the smaller islands lying approximately between 
0" and 12" S. latitude and 129" and 155". longitude. 
Additional information on the tabanids of the subre- 
gion appeared in two shorter papers (Mackerras 
1971, 1972). A few subsequent papers covering the 
fauna of other parts of the Australasian and Ocean- 
ian Regions were found, and some included taxo- 
nomic changes affecting generic and subgeneric 
names of species found in the Papuan Subregion. 
These changes were summarized by Daniels (1989) 
who provided the most current faunal list of Taban- 
idae for the Australasian and Oceanian Regions. In  
addition, Chainey (1988), which was not mentioned 
by Daniels (1989), included the description on a new 
species, Lilaea (Cyanolilaea) ismayi Chainey, from 
Papua New Guinea as  well a s  revisionary changes 
affecting names of other species from the Subre- 
gion. 
The new species described below is named for 
the Kamiali Wildlife Management Area in Morobe 
Province, Papua New Guinea. Commonly referred 
to as just Kamiali, the wildlife management area, 
has a marine and land surface area of a t  least 342 
km"possib1y as  much as 434 km 2, within the 
boundaries of the Lababia Village land area. It is 
located approximately 60 lcm SSE down the Huon 
Gulf coast from the provincial capitol of Lae. The 
land area of 269 km2 is covered by predominantly 
pristine coastal rain forest on the surfaces of moun- 
tains and ridges ranging from sea level to a little 
above 2,000 m. The people of Lababia and the 
smaller villages of the Kamiali have made the deci- 
sion to set aside most of the area as a wildlife 
management area rather than sell timber rights to 
private companies. They hope in this way not only 
to conserve their forest holdings for their descen- 
dants but also to derive income from activities for 
which the Kamiali will be the attracting force. 
Activities planned include hosting training work- 
shops, supporting visiting scientists interested in 
studies of the biota of the area, and ecotourism. 
They have been assisted in these endeavors by the 
Village Development Trust (VDT), a non-govern- 
mental organization with offices in Lae. Guest hous- 
ing, dining facilities, and a training center have 
been constructed, and the first training courses 
were carried out in late 1997. 
In addition, in early 1997, VDT entered into an  
agreement with the Environmental Research and 
Management Centre (ERMC) of the Papua New

an  inventory of the biodiversity of the Kamiali and 
to train some of the villagers to work with visiting 
scientists and to serve as guides. I was fortunate to

studies. I was warmly received by the villagers and

Identification: Although Mackerras (1971, 1972) 
include descriptions of species of Cydistomyia Tay- 
lor, none is closely similar to the species described 
here. Consequently, Mackerras (1964) includes the 
most recent key to the fauna of the New Guinea 
Subregion. In  the initial key to Cydistomyia in 
Mackerras (1964, p. 112), the genus is separated 
into three species groups. One, the basifasciata 
group, has  been returned to generic status as  the 
genus Chasmia Enderlein (Daniels 1989). Of the 
two remaining species groups, C. kamialiensis would 
key to the albithorax group. In the key to the 
albithoraxgroup (p. 131), i t  would key to C. imitans 
Oldroyd in couplet 1. 
In the description of C. inzitans Oldroyd provid- 
ed by Mackerras (1964, p. 136), he makes reference 
to a New Caledonian species, C. colasbelcouri Mack- 
erras and Rageau, noting that  C. imitans is distin-

a shining subcallus, orange antenna1 segment 3,  and 
brown abdomen. Examination of specimens of both C. 
ilnitans and C. colasbelcouri confirmed these differ- 
ences. 
Cydistomyia kalnialiensis differs from C. inzi- 
tans and C. colasbelcouri as follows: the pleura are 
densely golden pollinose and concolorous with the 
mesonotum, there are distinct tufts of long golden 
hairs below the wing bases anteriorly and posterior- 
ly, and the lateral margins of tergite one are densely 
golden pillinose and concolorous with the pleura, 
whereas, in C. imitans and C. colasbelcouri, the 
pleura are dark brown and contrasting with the 
golden colored mesonotum, the hair tufts below the 
wing bases are predominantly brownish, and the 
lateral areas of the first tergite are dark brown.
