Figures 127-130 

 Ichthyobelus Melichar, 1925a:360. Type-species: /. bellicosus Melichar, by 

 original designation and monotypy. 



Length 12-14 mm. 



Head strongly produced, the apex extended anteriorly into a process 

 which is elongate and troughlike or shorter and spoonlike, median 

 length exceeding transocular width, anterior margin carinate, ocelli 

 located on or slightly behind a line between anterior angles of eyes, 

 each slightly closer to midline than to adjacent eye angle, without a 

 median M -shaped elevation bordering posterior margin, with narrow 

 median fovea which broadens gready at base of median process, without 

 a longitudinal carina laterad of each ocellus, disc finely pubescent; 

 antennal ledges each with a longitudinal fovea in dorsal aspect, in 

 lateral aspect carinate dorsally, anterior margins steeply declivous; 

 clypeus concave medially, the concavity extending dorsally to anterior 

 margin of apical process, muscle impressions distinct; transclypeal 

 suture obsolete; face finely pubescent below; clypellus protuberant and 

 rounded, contour of its lower margin not continuing profile of clypeus. 



Thorax with pronotum slightly narrower than transocular width of 

 head, lateral margins subparallel, occasionally slightly concave at mid- 

 length, almost entire surface deeply punctate, the punctures each 

 bearing a short seta, posterior margin concave, with complete dorso- 

 pleural carinae, each of which is arched slighdy downward at mid- 

 length; scutellum transversely striate in posterior half. 



Forewing with membrane including all of apical cells, veins not very 

 distinct except at apex, basal half of clavus punctate, clavus and corium 

 coriaceous, with only four apical cells, the relative positions of bases of 

 the third and fourth somewhat variable, without an anteapical plexus 

 of veins on corium, usually with a few anteapical veins to costal margin, 

 wings of female at rest exceeding ovipositor. Hindwing extending almost 

 as far posteriorly as forewing; vein R2+3 obsolete. Hindlegs with, setal 

 formula 2:0:0 or 2:1 :0; first tarsomere with length less than combined 

 length of second and third. 



Male genitalia: Pygofer variable in form and chaetotaxy, with or 

 without a terminal process. Plates fused basally, extending farther 

 posteriorly than apex of pygofer, triangular, with numerous dispersed 

 microsetae or small macrosetae. Style elongate, slender, extending much 

 farther posteriorly than apex of connective, without preapical lobe, 

 rounded apically, with a few lateral microsetae in apical third. Con- 

 nective Y-shaped, with or without a median keel. Aedeagus symmetrical 

 or not, curved gradually posteriorly and dorsally, with various ante- 

 apical and apical processes. Paraphyses absent.
