CHIRONOMID MIDGES OF CALIFORNIA — SUBLETTE 89 



identified as P. carnea (Fabricius) . However, the wings and genitalia 

 of this species are distinctly different from those illustrated by 

 Goetghebuer (1936a, pi. 2, fig. 18; 1936b, pi. 5, fig. 71) for P. carnea 

 (Fabricius), and so I am considering it as new. I have not examined 

 Johannsen's material identified as P. carnea.

Pentaneiira (JPentaneurd) goniodes, new species 



Figure Ic 



Holotype male: USNM 65504, Berkeley, Oct. 3, 1947, W. 



Head yellow; antennal pedicel and flagellum brown; mouthparts 

 blackish. Eyes with long narrow dorsal extension. Antennal 

 ratio 2.00. 



Thorax stramineous, including legs; pollinose on prescutellar area 

 and on dorsolateral bristle row. Vittae orange-yellow. Prealar 

 bristles 14; dorsomedial bristles in staggered single row, which divides 

 around tubercle, then extends laterally as row on each side of pre- 

 scutellar area to join single dorsolateral row, thus forming cluster of 

 bristles on either side of midline just in front of scutellum. Sterno- 

 pleuron reddish-brown. 



Fore leg proportions: 75:92:70:35:25:16:8. Fore leg ratio 0.76; 

 middle leg ratio 0.50; hind leg ratio 0.65. Sparse hairs on fore tarsus 

 3 times as long as tarsal diameter. 



Wings hyaline, weakly haired on basal half. Ratio of arculus to 

 m-cu:m-cu to wing tip 0.46. Ri distal to CU2; R2+3 proximal to 

 Cui; R4+5 distal to Cu.. Squama well haired with small triangular 

 spot on distal margin. Wing length 3.29 mm.; venarum ratio 0.91. 



Abdomen with middorsal brown stripe. Segments II to V with 

 basal brown fascia; remainder of segments yellow. 



Female: Unknown. 



Paratype: Collected with holotype. Wing length 3.03 mm.; fore 

 leg ratio 0.71; middle leg ratio 0.54; hind leg ratio 0.65; antennal 

 ratio 2.00; venarum ratio 0.87; ratio of arculus to m-cu:m-cu to 

 wing tip 0.42. Both hind legs slide mounted. Both spurs sinuate; 

 longer spur with 5 lateral spines; shorter spur with 6 lateral spines, 

 ratio 42:70; comb of 7 long pale bristles. 



This species falls in Edwards' Group D of Pentaneura and in the 

 restricted group which Fittkau (1957) erected as genus Conchapelopia. 

 It closely resembles P.flavifrons Johannsen, P. alba Roback, P. rurika 

 Roback, and P. vitellina Johannsen, not Kieffer.^ 



2 Fittkau (1957, p. 320) clarified the status of vitellina Kieffer and pointed out that Johannsen (1946) had 

 misidentified the species. Fittkau then proceeded to propose anew name americana for vitellina Johannsen, 

 not Kieffer, based on Johannsen's figure 13. The propriety of Fittkau's action Is questionable since, accord- 

 ing to my understanding of the rules of nomenclature, a new name is to be proposed only in the case of 

 homonomy.
