Description
Female ( Figure 3a View Figure 3 ). Body length 1.10 mm, sparsely setose. Head, mesosoma and metasoma dark brown. Antenna, mandibles, wing venation and legs yellowish brown.
Head ( Figure 3b View Figure 3 ). Lateral and inferior area of face smooth, densely setose; in frontal view without ridge adjacent to torulus. Malar sulci simple. Occiput striated. Vertex smooth. Antenna with 13 articles, filiform; F1 longer than F2; F2–F11 subequal in length; F4–F11 with rhinaria. Compound eyes glabrous. Pronotum. Pronotal plate smooth. Medial bridge of pronotal plate narrow, with lateral foveae open and deep. Dorsal margin of pronotal plate slightly emarginated. Pronotal carina absent. Sides of pronotum slightly striated and sparsely setose behind genae.
Mesoscutum ( Figure 3a,c View Figure 3 ). Smooth and shining. Notauli absent. Parapsidal hair line present. Parascutal impression conspicuous.
Mesoscutellum. Scutellar foveae at base sculptured, broader than long. Lateral bars of scutellum smooth with a fovea beneath. Dorsal surface of scutellum ( Figure 3c View Figure 3 ) sculptured, areolate-rugose; posterior margin round. Scutellar plate ( Figure 3c View Figure 3 ) flat and smooth, not elevated above the scutellum, drop-shaped, covers 1/2 of scutellum in dorsal view; surface smooth without glandular pit; without a dark impression on the entire edge of scutellar plate.
Mesopectum. Mesopleuron slightly striated; with mesopleural carina and precoxal carina conspicuous, without subalar pit.
Metapectal-propodeal complex. Metapleuron strongly striated; anteroventral cavity conspicuous; posterior margin raised and hairy. Propodeum elongate, setose with sparse hairs between the carinae; lateral propodeal carinae subparallel.
Wings. Fore wings highly setose, hyaline, apical marginal with hair fringes quite long. Hairless towards the base of wing. Marginal cell ( Figure 3a View Figure 3 ) completely open, elongate, twice times as long as wide.
Legs. Mid- and hind coxae with a patch of hairs dorsolateral and posterodorsal, respectively.
Metasoma ( Figure 3a View Figure 3 )
Smooth and shining. Hairy ring at base of syntergum complete dorsally, with a weak row of long setae on each side posteriorly; distally smooth.
Variation: Body length 1.10–1.50 mm. Marginal cell twice or three times as long as wide.
Male. Unknown.
Etymology. In reference to weak striation of head, sides of pronotum and mesopleura.
Biology. Host unknown. Obtained on crop squash type Butternut ‘Anco’ ( Cucurbita moschata ).
Distribution. ( Figure 4 View Figure 4 ). Argentina. It is known only from La Plata, Buenos Aires province. This distribution belongs to Pampean province (Chacoan subregion).
Comments. Hydrelliaeucoila nonstriata sp. nov. differs from the other two species known from Argentina by presenting the following combination of characters: head and mesosoma dark brown (black in H. egeria ; reddish brown in H. rufa sp. nov.); lateral and inferior area of face smooth (striated in H. egeria ); head in frontal view without ridge adjacent to torulus (present in H. egeria and H. rufa sp. nov.); medial bridge of pronotal plate narrow (broad in H. egeria ); without a dark impression on the entire edge of scutellar plate (with a dark impression on the entire edge in H. rufa sp. nov.).
