midpiece is apparently suppressed or weakly discrete and small: the 
sidepieces are fringed with a single row of long hyaline filaments. 
The pleurograms (chitin lines) of the prosternum are abortive, short, 
and concursive with the pleuroprosternal sutures. On the anterior 
part of the body each sternite has a large, single, posterior porefield; 
posteriorly on the body these divide in two. The anterior parunguis 
(of each pretarsus) is short and thin (not grossly hypertrophied as 
in Eucratonyx and Sogophagus) . The coxopleural pores open singly 
and freely on all parts of the coxopleuron ; they are not cavitate. The 
ultimate tarsus is bipartite; its pretarsus is strongly unguiform. The 
gonopods of both male and female are entirely separated from each 
other, and each is distinctly bipartite. Anal pores are present. 
The two species differ from each other in the following notable, 
diagnostic characteristics. 
Zelanophilus provocator: (1) Ventral porefields absent on 3-4 
sternites anterior to the ultimate. (2) Final 4-5 sternites very densely 
clothed with fine setae. (3) First maxillary lappets absent. (4) First 
pedal tergite and those following on anterior quarter of body strongly 
bisulcate; the same tergites with extensive unpigmented areas. (5) 
First 4-6 spiracles very strongly and narrowly elliptical in shape. 
(6) Ultimate tergite much longer and narrower than that of pococki. 
(7) Central labral teeth deeply pigmented and as a group usually 
slightly separated from adjacent teeth. ( 8 ) Plagulae (smooth or 
lissate areas) of anterior clypeus typically large and prominent. (9) 
Pedal segments 67-77. 
Zelanophilus pococki: (1) Ventral porefields present on all ster- 
nites except the ultimate. (2) Final 4-5 sternites’ vestiture like that of 
those preceding, not contrastingly densely clothed with fine setae. 
(3) First maxillary lappets present. (4) First pedal tergite and those 
following on anterior quarter of body not sulcate or at most only very 
weakly so; the same tergites completely or nearly completely deeply 
pigmented. (5) First 4-6 spiracles round or nearly so, at most only 
very slightly, broadly elliptical. (6) Ultimate tergite much shorter 
and wider than that of provocator. (7) Central labral teeth weakly 
or not at all pigmented; as a group not separated from adjacent teeth. 
(8) Plagulae of anterior part of clypeus typically absent or at most 
very weak, small, and fragmented. (9) Pedal segments 59-73.
