Isodromus Howard 1887 

Hosts. Neuroptera  : Chrysopidae  , Hemerobiidae 

iceryae Howard 1887: 488 

Type. USNM

Distribution. W (Alameda, Contra Costa, Los Angeles, Marin, Napa, Orange, Riverside, San Bernardino, San Diego, San Luis Obispo, Santa Clara, Sonoma, Ventura)

Host/habitat. Ceraeochrysa cubana  , C  . lateralis, C  . sanchezi, C. valida  , Chrysoperla ploribunda  , C. rufilabris  , Leucochrysa floridana  , Sympherobius angustus  , Sympherobius californicus  ; NEW: Chrysopa nigricornis  ( EMEC)

Remarks. Icerya purchasi  and Saissetia oleae  were erroneously reported as hosts by several authors—these reports are attributable to parasitized Chrysopa  larvae, which pupated within the hollow shell of a dead scale ( Clancy 1946 a). Similarly, I consider the host report of Coccus hesperidum ( De Santis & Monetti 2008)  to be in error. Clancy (1946 a) also questioned the validity of hemerobiid host records, but noted that I. iceryae  would reproduce on Eremochrysa punctinervis  in the lab. A series of specimens was reared from galls of Heteroecus dasydactyli (Ashmead)  ( Hymenoptera  : Cynipidae  ) in San Bernardino County ( UCRC). Harrisina brillans  ( Lepidoptera  : Zygaenidae  ) is noted as the host for one specimen ( UCRC), but this is undoubtedly erroneous.

niger Ashmead 1900: 379 

Type. USNM

Distribution. W (Alameda, Los Angeles, Santa Clara, Solano, Ventura)

Host/habitat. Chrysopa nigricornis  , C  . oculata, C  . pallens, C. sp., Chrysoperla carnea  , Sympherobius angustus  , Hemerobiidae  sp.

Remarks. Clancy (1946 a) considered the only valid host records for this species were for the two closely related species, Chrysopa nigricorns  (= C. majuscula  ) and C. oculata  . Host records for Chilocorus similis  and Lymantria dispar (Linnaeus)  are clearly erroneous, while records for “ Chrysopa  ” may equally refer to Chrysoperla  .

puncticeps ( Howard 1885: 14)  ( Encyrtus  )

Type. USNM

Distribution. W (Stanislaus, Yolo) Host/habitat. Chrysopa  sp.

spp.

Remarks. A specimen determined as “sp. nr. axillaris ” ( Timberlake 1919 c), was recorded from Chrysopa nigricornis  in Contra Costa County ( EMEC), and what appear to be undescribed species near atriventris ( Ashmead 1900) were collected on aphid-infested Pinus sabiniana  in Calaveras County and Liriodendron tulipifera  ( Magnoliaceae  ) in Stanislaus County (both RLZC).
