Hexacnemus Timberlake 1926 

Hosts. Neuroptera  : Hemerobiidae 

armitagei Timberlake 1926: 15 

Type. USNM

Distribution. N (Lake, Ventura)

Host/habitat. Sympherobius californicus  , S. sp.

Remarks. Gordh (1979) noted that H. armitagei  has also been reported to parasitize mealybugs on citrus, probably based on a specimen from Florida ( USNM) that has “Mealybug, citrus” on the collecting label. Sympherobius  is predacious on mealybugs, and I suspect this is a mistaken host record, and the true host was an unrecognized hemerobiid. Noyes (2001) reported that a record of the genus from South America  (where it putatively attacked Aleurothrixus floccosus  and Planococcus citri  ) was in error. In fact, Parker et al. (1953) reported an Argentinean Hexacnemus  sp. “ex material” of these two species, noting that the parasites were reared “in grosso modo” from lots of material, and that the precise role of the parasite is not available. I have seen a male specimen ( USNM) of this parasitoid from Argentina  , and it is definitely a Hexacnemus  species, although I am unable to determine if it is conspecific with H. armitagei  . Additionally, the USNM has a female and male Hexacnemus  sp., reared in association with nymphs of Phenacoccus gossypii  , apparently from Columbia (CIAT- Palmira), that appear to represent an undescribed species of this genus.
