FLIES OF THE GENUS OGCODES — SCHLINGER 267 



Ogcodes {Ogcodes) philippinensis, new species 



Plate figures 37, 99 



Species of group v. This species is closely related to orientalis, 

 new species, from which it differs as follows: 



Male: Length of entire specimen 6.30 mm., wing length 5.25 mm. 



Head black, only eyes dark brown; antenna somewhat shorter, 

 oral area more U-shaped behind. 



Thorax with mesonotal margin dark brown, entire mesonotum 

 nearly black, postalar callus dark brown; venation as in plate 4, 

 figure 20, except M4 more gently curved at junction of m-cu crossvein; 

 squama a darker brown. 



Abdomen with dorsal spots yellow, larger, and with distinct dark 

 brown spiracular spots on tergites ii-iv, tergites 11 and in without 

 medial swellings, dorsal pile all about equal length; venter yellow 

 instead of white. 



Genitalia with wing of equal width throughout, somewhat broadened 

 at apex, median plate only about 1.15 times wingspread, its basal 

 cell more triangular (pi. 13, fig. 99); aedeagus somewhat more swollen 

 apically (pi. 7, fig. 37). 



Female: Unknown. 



Holotype: Male, Sibuyan Island, Philippine Islands (C. F. Baker, 

 USNM 64441). 



Remarks: This is apparently the fu'st recorded species of Ogcodes 

 from the Philippine Islands. Its closest relative is orientalis, as 

 discussed above. Both show a relationship to basalis (Walker) from 

 Australia, which suggests a Malay a-Australia-Philippines distribution. 



Ogcodes species of Palaearctic subregion 



Since Pleske (1930) and Sack (1936) have reviewed the Palaearctic 

 species, only pertinent notes and synonymy of those species seen will 

 be given here. The key presented by Sack (1936, p. 16) is quite 

 usable. The 13 species included in his review are as follows: etruscus 

 GrifRni, formosus Loew, fumatus Erichson, gibbosus (Linnaeus), 

 guttatus Costa, hirtus Sack, jacutensis Pleske, nigripes (Zetterstedt), 

 nigritarsis Shiraki, imllipes Latreille, trijasciatus Shiraki, varius 

 Latreille, and zonatus Erichson. Species not included in this work 

 are limbatus Bigot and varius var. siberiensis Brunetti, as well as three 

 subsequently described species, nigritarsis var. obusensis Ouchi, 

 esakii Ouchi (1942), and reginae Trojan (1956). This makes a total 

 of 18 species now known for this region. 



0. trijasciatus Shiraki (1932) is preoccupied by trijasciatus Meijere 

 (1915), and I propose shirakii, new name, for trijasciatus Shiraki at 

 this time. (See also data in list of species, p. 316.)
