Hyperexpanded ovipositor withfour apical valves and a patch of smal1 basolateralspines.Range.- Known from southwestern Oregon tosouthern California and southern New Mexico tocentral Texas.Texella Goodnight and GoodnightThe bifurcata GroupDiagnosis.-The presence of at least 9 pairs ofAT (Fig. 9) separates this group from the others.The males may be further distinguished by thefol1owing combination of characters: ventral surfaceof TrIV with tubercles, lacking spur (Fig. 11); POPabsent (Fig. 1); PSL2 present, mesal1y directed; Scompressed, basal1y unmodified, lacking SA; PSLlong, ribbon-like, apical1y bifurcate; apex of VPPwith ventral notch; AS long (2.5 times VP width)(Figs. 6, 12-15). The females appear to be unique inhaving a bent ovipositor (Fig. 18).Range.-Known from southwestern Oregon andnorthwestern California.Texella bifurcata (Briggs),New CombinationFigs. 1,6, 8-21Sitalcina bifurcata Briggs, 1968:29, figs. 31, 61,92, and 105 (male holotype from near westentrance of Castle Crags State Park, ShastaCounty, California, in CAS, examined).Diagnosis.-Males of this species are most easilydistinguished from other Texella by the presence oftransversely (rather than 10ngitudinal1y) directedPSL2 (Figs. 6, 15). Females have an ovipositor,possibly unique in the genus, which is bent (ratherthan straight) when ful1y extended (Fig. 18). Also,T. bifurcata differs from other species in the highernumber of AT (9-12 pairs, compared to 8-0 pairs inother Texella) which are arranged in two rows (abiserial arrangement is also found in T. kokoweef,jungi, brevistyla, reddelli, and diplospina) (Fig. 9).174
