RHYNONIRMUS 



Rhynonirmus Thompson, 1935. Parasitology, 27: 281. 

 Type species: Lipeurus infuscatus Osborn, 1896. 



Head variable in shape; strongly thickened along clypeal edge; 

 signature indefinite though an irregular transverse clypeal suture is 

 present; mouth parts unmodified; oral fossa remote, transverse, round- 

 ed, oblong. Trabeculae distinct, not exceeding the 1st antennal joint, 

 generally much shorter. Antennae variable in shape. Occipital edge 

 nearly straight. Metathorax very wide angled posteriorly. First 

 abdominal tergite with sides divergent; tergites transversely con- 

 tinuous, transparent near spiracles. Tergites II-VI meniscus shaped, 

 and the intertergal membrane becomes strongly chitinized in fully 

 adult specimens. Pleurites simple. Chaetotaxy, 1 dorsal and 1 ventral 

 row. Male genitalia. Basal plate widest posteriorly. Mesosome 

 triangular, shortly produced posteriorly; parameres excessively thin 

 towards inner edge, and closely fitting the mesosome. The latter 

 bears 1 pair of minute bristles on the wider portion, and 3 pairs 

 apically .

Rhynonirmus parsonae Clay, 1961. Bull. Brit. Mus . (N. H.), Ent., 



11: 50, figs. 9-11, and plate 1, figs. 2, 5 and 6. 

 Type host: Philohela minor (Gmelin) — American Woodcock. 



Male with tergite II completely separated and with 2 terminal and 

 2 subterminal setae on distal end of "penis". Female with tergites II- 

 V or VI deeply indented medially and VI or VII and sometimes VIII with
