This will key to couplet 3 in my 1958 paper along with P. bakeri Cook 
and P. discata Cook. The genitalia, however, have stout, uncurved 
gonocoxites and a median ventral process not evident in those 
species. 
Rhegmoclemina (Neoirlhegmoclemma) acrolophia, new species 
Male.—Length about 2.5 mm; dark blackish brown, head and thorax shining, abdomen 
dull, all concolorous. Antenna with 10 flagellomeres, each with a single whorl of about 19 
long setae as well as microtrichia and campaniform sensilla; maxillary palpi short (0.075 
mm), ovate; cardo-stipites indistinct, fused mesally, with 13 setae on each side; rostrum 
short, less than head capsule height; occiput setose with long setae, microtrichiose 
posteriorly; eyes with setae between facets. Spiracular sclerite triangular; supraalar setae 
14; preepisternals 18; anepisternals 14; upper episternals 9; subalars 11; subspiraculars 7 
(2 large); lower epimerals 0; pedicellars 0. Wing length about 2.5 mm, wing dull, densely 
microtrichiose; a few setae dorsally on Cu 1(> ; section 2 of costal margin short, shorter than 
R 3 . Abdominal terga 1-6 sparsely setose, setae more abundant on posterior segments; 
sternum 1 absent; sterna 2-6 like terga, with longer more numerous setae; tergum 7 short, 
with deep, rounded posterior emargination; sternum 7 (Fig. 6) shieldshaped, apodemes 
well separated; all sclerites with short, dense microtrichia; spiracles present on segments 
1-7. Genitalia (Figs. 7 and 8) similar to those of the African species R. chaetophora Cook 
and R. divergens Cook. Genital capsule produced ventrally as 2 long, slender, setose 
processes; the processes tipped by 2 or 3 setae and a blunt spiniform seta; penis valves 
dark, elongate, heavily sclerotized and assymetrical, each with few setae and/or campani¬ 
form sensilla apically; gonocoxites dark, heavily setose; penis stout, expanded apically, 
apex assymetrical.

(Schlinger and Ross). In collection of California Academy of Sciences. 
The only other described southern South American species is 
Rhegmoclemina constricta (Duda) from Chile. R. acrolophia has very 
different genitalia from those illustrated by Edwards in which there 
seems to be but a single pair of posteriorly directed appendages. 
Swammerdamelia glocHiis, new species 
Male.—Length 0.90 mm; blackish brown, dull, unicolorous except tarsi pale yellowish- 
white; halteres dark. Antennae damaged in the only specimen; maxillary palpi large, 0.10 
mm long; cardo-stipites with 3 setae on each side, microtrichiose; occiput sparsely 
setose, microtrichiose. Supraalar setae 10; preepisternals 3; anepisternals 10; upper 
episternals 5; subalars 6; subspiraculars 2; lower epimerals 0; pedicellars 1. Wings 
damaged on only available specimen. Abdominal terga and sterna sparsely setose, micro¬ 
trichiose; segment 7 largely concealed in segment 6; tergum 6 longer than preceding 
terga, without evident microtrichia except near anterior margin; segment 7 (Fig. 9) similar 
to that of S. pusilla, no specialized seta groups; genital vesica and apodemes 0.20 mm 
long. Genitalia (Fig. 10) with triangular gonocoxite; penis valves small, rounded lobes 
with few setae; aedeagal plate bluntly pointed, wider than long. 
Female.—Total length 1.05 mm, wing length 0.99 mm with typical venation, colored like 
male; maxillary palpi 0.11 mm long; cardo-stipites with 6 setae on each side; head other¬ 
wise as in male. Supraalar setae 9; preepisternals 2; anepisternals 9; upper episternals 5; 
subalars 4; subspiraculars 1-2, lower epimerals 0; pedicellars 1. Seven abdominal seg-
