Entedonomphale boccaccioi View in CoL sp. n.

Figs 10–14 View Figs 10–12 View Figs 13, 14

Etymology: This species is named after Giovanni Boccaccio.

Diagnosis: This species is defined based on the unique combination of the following morphological features: male antenna with a 2-segmented funicle and a solid clava (the only species of Entedonomphale known to have an undivided clava of the male antenna); female antenna with a slender scape and relatively small funicle segments, their combined length much less than length of clava (F1 without sensilla); both sexes: forewing disc hyaline, with setae very short and inconspicuous, marginal setae short; apex of hind wing broadly rounded. Morphologically, the female of E. boccaccioi sp. n. is somewhat similar to the much darker (black) female of another North American species, E. nubilipennis , which has a narrower forewing (about 3.0 x as long as wide) with a medial cloud on the disc and relatively longer marginal setae.

Description: Female ( holotype and paratype). Body and appendages brown to dark brown except F1 light brown.

Head normal, not compressed dorso-ventrally; vertexal suture faint but distinct. Antenna ( Fig. 10 View Figs 10–12 ) with scape slender, about 3.0 x as long as wide; F1 a little longer than wide and without sensilla, F2 a little wider than long and with 1 sensillum; clava much longer than funicle, about 2.3 x as long as wide, with numerous sensilla.

Mesosoma shorter than metasoma, almost smooth. Midlobe of mesoscutum with 2 pairs of setae; anterior margin of scutellum almost straight. Forewing ( Fig. 11 View Figs 10–12 ) about 2.7 x as long as wide; longest marginal setae about 0.28 x maximal forewing width; disc hyaline, more or less evenly setose in apical half of forewing (setae very short, inconspicuous). Hind wing ( Fig. 12 View Figs 10–12 ) about 6 x as long as wide, with broadly rounded apex; disc relatively wide, with several rows of setae, more or less evenly covered with short, inconspicuous setae; longest marginal setae about 3/4 maximal width of hind wing. Coxae lightly sculptured.

Figs 15, 16. Entedonomphale bicolorata , female ( paralectotype of Thripoctenoides gaussi ): (15) antenna, (16) forewing. Scale lines = 0.1 mm.

Petiole conspicuous, longer than wide (length/width ratio about 1.5:1). Ovipositor relatively short, occupying a little less than 1/2 length of gaster, not exserted; ovipositor length/metatibia length ratio about 1.3:1.

Measurements (n=1, holotype). Body: 1661. Antenna: scape: 203; pedicel: 64; F1: 38; F2: 36; clava: 139. Forewing: 923/339; longest marginal seta: 97. Hind wing: 824/136; longest marginal seta: 96. Ovipositor: 358.

Male ( paratype). Body length 1292. Generally similar to female except for colouration of antenna (all segments brown) and normal sexually dimorphic features such as antenna and genitalia. Vertexal suture indistinct. Antenna ( Fig. 13 View Figs 13, 14 ) with a 2-segmented funicle and a solid clava; flagellar segments with numerous long setae. Petiole a little shorter than in female. Genitalia as in Fig. 14 View Figs 13, 14 .
