Tomoplagia punctata, new species 



Figures 100,m-p; 102,t,u; Plate 25, figure 23 



This median-sized species is similar to stonei in having unusually 

 large, shining dark brown insertion points of the dorsocentral and 

 prescutellar bristles on the mesonotum, but is easily distinguished 

 from stonei by the characters given in the key. 



Male: Length 4.5 mm.; wing 4.4 mm. long and 1.8 mm. broad, 

 2.4 times as long as broad. 



Head 0.68 mm. long, 1.43 mm. wide and 1.16 mm. high, pale ochra- 

 ceous yellow except for the testaceous yellow frontal vitta; ocellar, 

 genovertical, parafacial, and mesofacial plates with fine white pruin- 

 osity but no distinct vittae on frons. Antennae and maxillary palpi 

 ochraceous yellow, labella yellowish brown. Ocellar plate consider- 

 ably raised; oral margin of mesofacial plate raised and prominent. 

 Inferior region of cerebral plate slightly raised. Maxillary palpi 

 broad-oval, not curved, with widely rounded apex. Postpedicel very 

 broad-oval, 0.21 mm. long and 0.18 mm. wide, about 1.1 times as 

 long as wide. Seta bare, shining black except for the testaceous 

 yellow, thickened third, almost three times as long as postpedicel. 

 Eyes in profile 0.91 mm. high and 0.54 mm. wide, nearly 1.7 times as 

 high as wide. Inferior region of postcranium in profile 0.20 and genae 

 below eyes 0.14 mm. wide. 



Cephalic bristles pale brownish yellow; the usual garniture present 

 and the relation in length among them is the same as in reimoseri, 

 only the genal bristle is distinct. 



Thorax with scutellum 2.1 mm. long and only 1.3 mm. wide, pre- 

 dominantly ochraceous yellow; mesonotum with the same pruinose 

 pattern as in heringi: densely covered with silky whitish dusting and, 

 except for the shining narrow hind margin, rather thick short whitish 

 hairs; in the whitish pruinosity three light golden yellow vittae, 

 slightly wider than in heringi, one on median line and two in lines of 

 dorsocentral pair, on both sides of mesonotum before transverse suture 

 a broad and short vitta reaching to insertion point of the presutural 

 bristles. The chitin insertion circlets at base of dorsocentral and pre- 

 scutellar bristles unusually large and shining dark brown, which is a 

 distinct character of this species. The usual pair of black oval spots 

 present on hind region of mesonotum, and the usual black dot behind 

 (and beneath) wing base. Pleura shining except for the mesopleuron 

 and "hypopleura" (katepimeron), and marked with the same three 

 spots as in reimoseri. Scutellum shining ochraceous yellow, with some 

 dark brown scattered hairs on sides. The larger median part of post- 

 scutellum yellow, whitish pruinose, lateral parts black. Mediotergite 

 shining testaceous yellow. 



Thoracic bristles pale brownish yellow, somewhat flattened; in- 

 ferior mesopleural bristle only slightly shorter than superior; posterior
