Prefemoral Process — There are three basic types of prefemoral 

 processes: the short projections of Selenocheir that are less than half 

 as long as the acropodites (Figs. 54-55, 60-61, 65-66); long ones, as 

 long or longer than the acropodite, that are narrowly blade-like to 

 subacicular (Figs. 35-38, 47-48, 52-53); and long ones that are expand- 

 ed, broad, and laminate (Figs. 3-7, 10-13, 16-19, 22-25, 30-31). The 

 distally expanded, trifurcate projection oi Montaphe paraphoena (Figs. 

 42-43), shorter than the acropodite, is an exception. The massive 

 structures of Chonaphe and Semionellus are especially lamellate distad. 

 In Chonaphe, the projection is upright and expands at about 1/3 length 

 into a narrow shelf or ledge on the dorsal side. The outer margin of 

 the ledge extends distad a short distance as a translucent shield; in C. 

 schizoterminalis a distal angular flap on the stem of the prefemoral 

 process overlaps the shield to form a tube; and in C. remissa the 

 shield connects to the inturned lateral margin of the stem to form a 

 continuous lamina that extends to the tip of the process. The distal 

 part of the acropodite inserts onto this shield or through the tube and 

 extends for varying lengths, emerging from behind the shield and 

 becoming visible in medial view in C. armata and evexa (Fig. 5), 

 while being obscured by the continuation of the shield and its linkage 

 with the inturned lateral margin in C. remissa (Fig. 11). Distal to the 

 shelf, there is the flap of C. schizoterminalis (Fig. 23), a low angular 

 ridge in C. evexa (Fig. 18), and a thickened, convoluted projection in 

 C. armata and remissa about halfway between the ledge and the tip 

 (Figs. 5-6, 11-12). Taxonomically, the most important aspect of the 

 prefemoral process of Chonaphe is the apical configuration, which is 

 a modification of a basically subdivided structure. In C schizoterminalis, 

 the tip is deeply divided lateral to the midline into two apical projections, 

 a narrow, lateral, dactyliform branch that is subequal in length to the 

 larger, medial branch (Figs. 22-24). The process is apically entire in 

 C. evexa, but the subterminal lateral margin turns inward for a short 

 distance to form a narrowly rounded lobe, suggesting an apical division 

 that has become subapical as the apical-medial margin has enlarged 

 and expanded (Figs. 18-19). The impression that I receive from C. 

 armata and remissa is of formerly divided apices that have rejoined, 

 with the suture line still being evident in the latter, particularly when 

 viewed in ventral perspective (Fig. 13). In both species, it is as if a 

 previous division has disappeared, leaving a vertical, coaxial flap or 

 sclerotized, marginally serrate lamella in C. remissa (Figs. 10-12), 

 and an inturned, subacuminate, transverse medial corner in C. armata
