Tyttholeon puerilis Adams, 1956:107 [Holotype male, Palm Springs, Riverside County, California, 27.vi.1939, E. Linsley Coll., Type Nº 7210 (CAS)]. – Stange, 1970: 50, 157, 180, 183 [redescription, taxonomy, distribution,illustrations].– Martins Neto and Vulcano,1989: 379 [forewing illustration]. – Stange and Miller 1990: 159 [larva head photograph]. – Stange, 1994: 111, 113, 114, 117 [illustrations, larva photograph]. –

Penny et al., 1997: 86 [taxonomy, distribution]. – Oswald et al., 2002: 581 [distribution]. – Stange, 2004: 252 [taxonomy, type, distribution].

Distribution. Mexico (BC), USA (AZ, CA, NV).

Diagnosis. Clypeolabrum height more than half eye width; narrow wings with sparse wing venation; hind basitarsus shorter than distal tarsomere; male ectoproct without postventral lobes; paramere teeth broad, short, oblong, straight and pointing posterodorsally, very basad to paramere plates; lateral gonapophysis with short digging setae; posterior gonapophysis with long hairlike setae.

Larvae. In Stange (1994).

Remarks. This species was firstly registered from Baja California by Oswald et al. (2002). It can be readily differentiated from T. froehlichi n. sp. by the sparser wing venation, the male ectoproct without postventral lobes and the hindleg basitarsus shorter than the distal tarsomere. The type specimen is covered in pollen ( Fig. 12 ), which is interesting as the gut content of this species was previously reported as containing solely aphids ( Stange, 1970).

Material examined. (1♂, 1♀) United States – California: Lassen Co., 11 km N Doyle on Hackstaff Rd; 0º06’59.4”N, 120º07’20.1”W, 1266 m; 08-24.vii.2019; 1♂, 1♀; Malaise with Artimesia tridentata on sand; ME Irwin, GR Ballmer ( CNIN) .
