Proamblia Bergroth

( Figs. 2 A–D, 7, 8)

Proamblia Bergroth 1910: 236 (n. n. for Modigliania , n. praeoc. by Modigliania Perugia, 1893 —Pisces), type species: Modigliania cunealis Poppius, 1909 (original designation); Proamblia: Bergroth 1920: 73 ; Carvalho 1952: 50, 1955a: 22, 1957: 32; Schuh 1995: 35; Gorczyca 2000: 50, Gorczyca 2006: 72

Modigliania Poppius 1909: 2 , 3, 43, type species: Modigliania cunealis Poppius, 1909

1909 (original designation); Modigliania Poppius 1909: 2 , 3, 43; Modigliania: Reuter 1910: 155 ; Carvalho 1952: 50, 1957: 33; Schuh 1995: 35

Diagnosis. Recognized by having the following set of characters: body elongate-oval ( Fig. 2 A–D); head declivous; maxillary and mandibular plates broad; labrum without any spines ( Fig. 7 A); pronotum shining, covered with sparse, decumbent setae ( Figs. 2 A–D, 7A, C); posterior lobe of pronotum densely and coarsely punctate ( Figs. 2 A–D, 7A, C); hemelytron dark brown with yellow patches ( Fig. 2 A–D); endosoma elongate, strongly membranous, with single, long, relatively broad sclerite ( Fig. 8 A, B, F, G). Proamblia is most closely related to Mycetocylapus but can be easily distinguished by the punctation of the pronotum and hemelytron, and by the body shape.

Redescription. COLORATION ( Fig. 2 A–D). Dorsum dark brown with yellow and brownish areas. Head. Antennal segment II always dark brown to black apically; segments III and IV dark brown, segment III with narrow, pale annulation basally; labial segment IV always brownish, pale yellow apically. Thorax. Mesoscutum and scutellum. Mesoscutum varying from dark brown to almost black; scutellum yellowish brown with more or less distinctly marked, dark brown patch medially. Hemelytron. Dark brown with yellow areas; clavus yellowish medially; corium slightly yellowish basally, with distinct, yellow patch medially, and with two yellow patches apically, one of which situated at inner angle, and borders clavus apically, second situated at extreme apex of corium; embolium yellow; inner angle of cuneus yellow; membrane dark brown with yellowish patches. Legs. Coxae pale yellowish; forecoxa slightly darker than meso- and metacoxae; remaining segments dull yellowish. STRUCTURE AND VESTITURE ( Figs. 2 A–D, 7). Dorsum shining, covered with short, decumbent setae. Head. Declivous, broad in frontal view, covered with fine, short, decumbent setae; gula covered with several long, protruding, thick setae; vertex slightly rounded; longitudinal sulcus in medially of vertex shallow; frons rounded; maxillary and mandibular plates broad; clypeus almost vertical, not visible in dorsal view, slightly narrowed basally, somewhat more protruding apically; labrum horizontal; eye rounded, relatively small, somewhat protruding, slightly removed from pronotal collar, not reaching gula; antenniferous tubercle almost contiguous with margin of eye; antennal segment I, covered with moderately dense, semidecumbent, relatively thick setae, slightly narrowed basally, then cylindrical; segment II somewhat thickened apically, shining, sparsely covered with fine, almost decumbent setae, apex matte, covered with dense, thick, dark, almost black, semidecumbent and decumbent setae; segments III and IV covered with relatively long, semidecumbent, thick setae; rostrum relatively thin, long, reaching distinctly beyond metacoxae; labial segment IV short. Thorax. Pronotum. Pronotal collar matte, rounded, devoid of setae; posterior lobe covered with fine, short, decumbent setae; thin, transverse, punctate depression between pronotal collar and anterior lobe; anterior lobe with thin, shallow longitudinal sulcus; posterior lobe coarsely and deeply punctate; lateral margins rounded laterally, not carinate or with hardly visible, indistinct carina. Mesoscutum and scutellum. Mesoscutum raised; scutellum covered with sparse, fine setae; with a distinct, transverse depression between mesoscutum and scutellum; scutellum rather convex, rugose. Hemelytron. Slightly rounded laterally, covered with fine, decumbent, pale setae; suture on clavus swollen; embolium impunctate, slightly elevated basally; membrane with major cell triangular; minor cell clearly present. Thoracic pleura. Propleuron glabrous, shining, impunctate anteriorly, deeply and coarsely punctate posteriorly; remaining pleura rugose. Legs. Relatively long, covered with moderately dense, decumbent and semidecumbent setae; claw not toothed subapically.

Male genitalia ( Fig. 8 ). Aedeagus elongated, distinctly membranous; ductus seminis with sclerotized portion within endosoma relatively long; endosoma with single, longitudinal sclerite.

Female genitalia. Not examined.
