Treatment

Tarsostenus antehelvis OPITZ , nov.sp. ( Figs 14 View Figs 2-21 , 42 View Figs 41-43 , 65 View Figs 63-66 , 85 View Figs 83-88 , 91 View Fig )

Holotype: Ƌ. PAPUA NEW GUINEA, Western Highlands, Jimi River , 4700 ft., 16.7- 21.9.1961, W. W. Brandt ( ANIC).

Paratypes: One specimen from the same locality as the holotype ( ANIC).

D i a g n o s i s: The elytral disc is predominantly black. It has a narrow dim white fascia at the middle. The elytral asetiferous punctations are present throughout the elytral disc, and the capitulum is elongate. These characteristics will distinguish the members of this species from congeners.

D e s c r i p t i o n: Size: Length 4.0 mm; width 1.2 mm. Form: As in Fig. 65 View Figs 63-66 . Integument: Forebody testaceous, pterothorax black, legs brown, except profemur half testaceous, abdomen black, elytron bicolored, predominantly black, with dim white fascia at middle. Head: Cranium coarsely punctate, frons wider than width of eye (FW/EW-23/18); antennal funicular antennomeres subfiliform, 9 th and 10 th antennomeres triagonal, 11 th oval ( Fig. 14 View Figs 2-21 ). Thorax: Pronotum coarsely punctate, with slightly developed lateral tubercle and with three glabrous elevations near base ( Fig. 42 View Figs 41-43 ) ( PL /PW- 60/57); elytral disc with prominent asetiferous punctations that extend to elytral apex, with 1° and 2° ( EL /EW- 210/40). Abdomen: Male pygidium not incised at middle of anterior margin; phallobase slightly sclerotized ventrally, lobes very small, fimbriate, phallobasic rod very long, phallobasic struts not contiguous with phallobasic apodeme, phallic apex triagonal, phallic plates narrow, spicular apodemes fused ( Fig. 85 View Figs 83-88 ).

V a r i a t i o n: The two specimens before me are quite homogeneous.

N a t u r a l H i s t o r y: The two available specimens were collected during a time period from July 16 through September 21, at 1433 m.

D i s t r i b u t i o n ( Fig. 91 View Fig ): This species is known only from Papua New Guinea.

E t y m o l o g y: The specific epithet antehelvis is a Latin compound name derived from ante (= before) and helvus (= yellow). The name refers to the coloration of the forebody.
