Nothotragopus zimmermani Setliff , new species

( Figs. 6–7 , 12 , 22–25 )

Diagnosis. This species differs from its congeners by the combination of its larger size (length 9.5 mm, greatest width 4.1 mm), unmodified ventral apex of the female rostrum ( Fig. 12 ), pronotum and elytra with densely matted squamae interrupted by symmetrical glabrate patches ( Fig. 7 ), and the apex of the female tergite VIII strongly emarginated, smooth, and set with short, stout setae on either side of medial indentation ( Fig. 24 ).

Description. Adult habitus. Length 9.5 mm, width 4.1 mm. Integument black, antennae and tarsi reddish-brown; dorsum covered in small, densely distributed, circular, prostrate scales; scales flocculent, closely appressed into dense mats that obscure cuticle except in glabrate patches. Dorsum with occasional iridescent green scales, very sparsely distributed, mostly obscured by brownish squamae, can only be seen under high magnification. Vestiture patchy; pronotal disk with pair of large glabrate patches on posterior margin, irregular circular patch on lateral sides of pronotum; elytra with median basal patch extending almost to elytral declivity, irregular circular patch on lateral anapleural margin of elytra. Pleura, legs, and venter densely clothed in brown, semierect elliptical scales, interspersed with longer, pale, semierect scales on legs. Head. Rostrum arcuate, as long as pronotum. Antennae inserted slightly beyond middle of rostrum; scape not reaching eye; club ovate, shorter than funicular articles 1 and 2 combined. Thorax. Pronotum slightly broader than long; fine medial carina visible at anterior margin and again at middle of pronotal disk; arrangement of shiny granules on lateral sides of pronotum confused. Ceiling of prosternal canal and mesosternal receptacle glabrous, lateral margins and sides of canal squamose. Mesosternal receptacle widely open. Scutellum small, subcordate, strongly protruding. Elytra and pronotum strongly convex in lateral view; granules on elytra irregular, each bearing one long, decumbent seta; humeri slightly produced but elytra not significantly wider than pronotum; elytral punctures large, shallow, mostly obscured by squamae except in patchy areas. Interval 3 with multiple rows of granules, elevated above other intervals at a short distance from base and terminating at elytral declivity; interval 2 likewise slightly raised and granulate, but to lesser extent than interval 3, elevated more toward midline. Protibia with long, erect, hair-like setae on ventral margin. Hind femur exceeding well beyond elytral apices. Female terminalia. Tergite VIII longer than broad, moderately curved ventrad, apex smooth, strongly emarginate at center, set with short stout setae arising submarginally on ventral and dorsal surface on either side of indentation ( Fig. 24 ).

Type material examined. Holotype: 1 ♀. [formerly a syntype of Cyamobolus tragopoides Heller ]: ‘‘ Mt. Guntur Garoet , West Java 1,350 m., Overbeck leg/1934, 8/ Syntypus’ ’ [ SMTD].

Dubious material. Males provisionally determined: 1 Oi. [formerly a syntype of Cyamobolus tragopoides Heller ]: ‘‘Leg. H. Lucht, K. O. Blawan [Plawan in Heller 1940: 103], Idjen-Plateau, Java, 900–1,500 m., I. IX. 1934 /Hell FCD 50/1939, 16/ Syntypus’’ [ SMTD]. 1 Oi. ‘‘E. Java, SW Madiun, Gn. Lawu, Sarangan, Cemara Sewa/ 1,800 –2,200 m. 11–12. VII. 2003 leg A. Riedel’’ [ MZB]. 1 Oi. ‘‘Bremi, 900– 1,900 m. 16. VII. 2003, leg. A. Riedel/E. Java, SE Probolinggo, Gn. Argopuro’’ [ ARC]. 1 Oi. ‘‘12/9/20, Tengger, U. D. v. L [?], Voogi [?] [label illegible] /[ DEI]. I tentatively assign these males to N. zimmermani based on the similarity of the patchy dorsal vestiture and robust facies; male specimens are excluded from the type series.

Etymology. The specific epithet is a patronym honoring the late E. C. Zimmerman, expert on Oceanic and Australian Curculionoidea and author of Nothotragopus .
