- Euplectrus leucotrophis Howard, 1885: 26. Lectotype ♂ (USNM), designated here, examined.
Material
Type material: 3♂ syntypes of Euplectrus leucotrophis, one of which is selected lectotype here (USNM).
Diagnosis
Entire lower face white with median part yellowish-white (Fig. 700); scape slightly expanded and widest in apical part, 3.6× as long as wide (Fig. 700), sensory pores confined to apico-ventral part, sensory area with same colour as scape; legs white; petiole 0.6× as long as wide, with posterior margin strongly curved forwards (Fig. 702); gaster with anterior ½ yellowish-white with anterolateral margins dark brown, margin broken medially by white stripe, posterior ½ dark brown (Fig. 701).
Description
Male. Length of body 1.3 mm. Antenna with scape white, pedicel yellowish-white, flagellomeres missing in type specimens; scape slightly expanded and widest in apical part (Fig. 700), sensory pores confined to apico-ventral part, sensory area with same colour as scape. Mandibles and palpi white. Head dark reddish-brown and shiny, entire lower face white with median part yellowish-white (Fig. 700). Frons close to eyes with a row of setae and with some setae parallel to this row. Vertex smooth. Occipital margin with a weak carina behind ocellar triangle.
Mesosoma dark reddish-brown (Fig. 699). Each sidelobe of mesoscutum with eight setae. Scutellum 1.1× as long as wide; with very weak engraved reticulation, with posterior margin smooth. Dorsellum anteriorly without a groove or foveae. Propodeum smooth; anteromedially with a transverse semicircular cup; propodeal callus with six setae. Legs white (Fig. 699). Fore wing: costal cell with two rows of setae on ventral surface, and margin with four setae close to marginal vein; with 12 admarginal setae, in one row.
Gaster with anterior ½ yellowish-white with anterolateral margins dark brown, margin broken medially by white stripe, posterior ½ dark brown (Fig. 701).
Ratios. HE/MS/WM = 2.5/1.0/1.5; POL/OOL/POO = 5.3/2.0/1.0; OOL/DO = 0.8; WE/WF/WH/HH = 1.0/2.4/4.7/3.6; LC/WS = 3.6; WH/WT = 1.3; PM/ST = 1.2; TS1/TS2/LT/LT1/LT2/LT3/LT4 = 2.7/1.5/5.0/1.4/1.2/1.0/1.3; LP/WP = 0.6; MM/LG = 1.7.
Female. Unknown.
Hosts and biology
Recorded as “Arctiidae indet.” (Howard 1885[1]), but highly unlikely to be the host. Arctiidae is nowadays classifed as a subfamily (Arctiinae) in Erebidae.
Distribution
USA (Florida) (Howard 1885[1]).
Remarks
The syntype series consists of three males. One male is on a strongly corroded pin and this specimen lacks the head. Two males are glued to the same card, specimen to the left lacks entire left antenna and pedicel+flagellum on the right antenna, the right hindwing, hind legs, tarsus on right midleg; specimen to the right lacks the flagellum on the left antenna and pedicel+flagellum on the right antenna, tarsus on right fore and mid legs, and right wing-pair. The lectotype is the male to the right of the two males glue to the same card. Labels on the pin: “No.647.a. July 19.80 [1880]”, “Type No. 2654 U.S.N.M.”, “Euplectrus leuctrophis How. ms.”. All specimens have a pale appearance which might be due to bleaching by light.
