Prochiloneurus argentinensis ( De Santis, 1964) ( Encyrtidae )

( Figs. 34–35 )

Achrysopophagus argentinensis De Santis 1964: 357–359 . Type locality: San Javier, Tucumán, Argentina. Holotype female [MLPA], photographs examined ( Noyes & Triapitsyn 2018).

Prochiloneurus sp. : Triapitsyn et al. 2014a: 178 (female from El Portezuelo, Catamarca, Argentina), 184 (illustration).

Prochiloneurus argentinensis (De Santis) : Löhr et al. 1990: 423 (list of hyperparasitoids); Noyes & Triapitsyn 2018: 14–15 (mentioned), 18 (illustrations of the female from Catamarca, Argentina), 19 (illustrations of the holotype), 21 (mentioned), 22–25 (resurrection as a valid taxon from the previous synonymy under Prochiloneurus dactylopii (Howard) , taxonomic history, redescription, diagnosis, distribution, host associations), 34 (mentioned).

Material Examined. ARGENTINA, Córdoba, near Mina Clavero, Vivero Córdoba, 31.7576°S, 64.9724°W, 1015 masl, collected 31 Mar 2017, M. B. Aguirre, S. D. Hight, G. A. Logarzo, S. V. Triapitsyn, emerged 17 to 24 Apr 2017 (from Hypogeococcus sp. on San Pedro cactus, Echinopsis pachanoi ) [2 females, UCRC].

Other Material Examined. ARGENTINA, Misiones , Loreto, 14 Jul 1935, A. A. Ogloblin (“s/ larva de Pentilia egena Musl. [sic]”) [1 female, 2 males, MLPA] .

Description. Male (previously unknown; from Loreto, Misiones, Argentina). Illustrated are its habitus ( Fig. 34 ) and antennae ( Fig. 35 ). Most of mesofemur (except basally) and metatibia dark.

Distribution. Argentina (Catamarca, Córdoba [new record], Misiones [new record] and Tucumán), Brazil, and Guyana ( De Santis 1964; Löhr et al. 1990; De Santis & Fidalgo 1994; Triapitsyn et al. 2014a [as Prochiloneurus sp. in Catamarca]; Noyes & Triapitsyn 2018).

Hosts. A hyperparasitoid of Hypogeococcus pungens s. str. on Alternanthera pungens , probably via an Anagyrus sp. primary parasitoid of this mealybug in Catamarca, Argentina ( Triapitsyn et al. 2014a [as Prochiloneurus sp. ]; Noyes & Triapitsyn 2018), and also of Hypogeococcus sp. (likely via A. quilmes in Córdoba), as well as of Phenacoccus herreni Cox & Williams ( Pseudococcidae ) ( Löhr et al. 1990; De Santis & Fidalgo 1994). The above record of this species from a larva of Pentilia egena Mulsant ( Coleoptera : Coccinel- lidae) is interesting but quite unusual, so we do not really know how trustworthy it is, even considering that A. A. Ogloblin was an experienced and very knowledgeable entomologist.
