Pictipes Group 



Diagnostic characters (figs. 9, 79). — Related to the Notata 

 Group, but differs markedly in its unmarked wing and punctate legs. 

 Medium to large species, with showy ornamentation of legs, thorax, 

 and abdomen. Eyes moderately separated. Female antennae with 

 III-X pale except for dark apices which are strongly constricted, 

 XI-XIII with narrow whitish bases, XI-XV otherwise dark. Palpus 

 dark except V pale; III short and bristly, constricted on distal fourth, 

 without sensory pit, a few long sensilla scattered distally. Mandible 

 with 7-8 strong teeth, 3-4 outer serrations. Thorax produced antero- 

 dorsally in a small blunt tubercle; scutellum with 4 large bristles. 

 Legs pale, not unusually bristly, femora with narrow subapical dark 

 rings, tibiae with prominent dark speckling; female with moderately 

 long claw and short claw appearing as basal tooth, male claws sub- 

 equal; tarsomere III slightly longer than IV, V with subbasal pair of 

 stout batonnets on fore and mid legs, unarmed on hind leg. Wing 

 with IRC well formed, 2RC short and broad, vein R 4+5 thickened 

 usually from r-m crossvein onward, and with marked expansion 

 where it turns distally to meet the costa; both Ri and extreme tip of 

 R 4+5 faint at costa. Abdomen pale with conspicuous dorsal color 

 pattern; terga moderately setose and with conspicuous clumps of 

 long stout setae centrally at least on II to IV. Two sclerotized func- 

 tional spermathecae plus a rudimentary third, the second much 

 reduced in size. Male genitalia with tergum IX short and rounded 

 distally, sternum IX ribbonlike; basistyle short, mesal margin mid- 

 way with a conspicuous platelike lobe, basidorsal roots long, nearly 

 meeting mesad; dististyle long, curved and slender distally; aedeagal 

 sclerites slender, rodlike, or curving bladelike, caudomedian tips not 

 modified; parameres stout, bases knobbed and bent, curving distally 

 to bent, bluntly pointed tips.
