Lemodes (Lagriomorpha) punctata , NEW SPECIES

( Figs. 5–7 )

Description. Length 4.4 mm (n=1). Dorsal and ventral surfaces, legs, and antennae moderately densely covered with short, mostly decumbent setae, dorsum and elytra also with numerous, longer, semierect to erect setae.

Adult (sex undetermined) (Dorsal habitus: Fig. 5 ). Head and mouthparts rusty orange-brown; mandibles rufopiceous, at least in part. Dorsal surface of head ( Fig. 6 ) confusedly, moderately deeply, densely, coarsely punctate, cranial neck coarsely, closely punctate. Compound eyes small, somewhat coarsely-faceted, slightly protruding. Tempora well-developed, length subequal to that of dorso-longitudinal length of compound eye, obtusely produced posteriorly. Antennae with segments 1–2 orangish-brown, antennomere 3 rufopiceous proximally, darker distally, antennomeres 4–9 black, antennomeres 10–11 creamy yellowish-orange; antennae densely covered with stout, semierect and erect setae; antennomeres 4–10 submoniliform; 11th antennomere more than 1/2 again as long as antennomere 10, slightly acuminate distally. Terminal segment of maxillary palpus somewhat expanded distally. Visible dorsal and ventral surfaces of thorax rusty orange-brown; pronotum ( Fig. 7 ) hourglass-shaped, widest anterad the middle, densely covered with rust-orange setae, coarsely, densely, moderately deeply punctate; prothoracic coxal cavities widely open externally; scutellum rusty orange-brown, shield-shaped, distally rounded, bearing retrorsely decumbent, coppery-orange setae; mesosternum, metasternum and mesothoracic episterna with scattered, large, shallow punctures; mesothoracic episterna meeting anteromesad the mesosternum. Legs orangishbrown; paired, dorsal tibial carinae present; tibial spurs very short, stout; penultimate tarsomere slightly dilated, bilobed; tarsal claws simple. Elytra rusty orangish-brown, elongate, 2.6X longer than width across sub-basal humeral area, covering abdomen, margins subparallel along basal 1/3 of length, slightly wider in distal 1/3; elytral surface rather coarsely, densely, confusedly, moderately deeply punctate, surface between punctures smooth to punctulate. Metathoracic wings fully developed. Ventral surface of abdomen unicolorous, orangish-brown.

Types. Holotype (sex undetermined, SMNS) [card-mounted] [First label]: [NEW GUINEA] IRIAN JAYA: Anggi; Tetaho// Iranmcba 1500–1700m // 25.III.1993 // leg. A. RIEDEL; [Second label]: Auto-Montaged// digital image(s)// per D. K. Young; [Third label]: HOLOTYPE:// Lemodes // (Lagriomorpha)// punctata // Young.

Distribution. As detailed above, L. punctata is presently known only from the holotype and type locality near the Anggi Lakes: Gigi (- 1.366743° S, 133.894701° E) and Gita (- 1.393074° S, 133.957869° E), in the mountains at the eastern end of the Yogelkop Peninsula, 60 km SSW of Manokwari, Province of West Papua, Indonesian New Guinea.

Diagnosis. The small size (4.4 mm) and unicolorous, rust-orange elytra easily separate this species from all other members of the subgenus Lagriomorpha with the exception of L. telnovi . The tempora of L. punctata are more produced ( Fig. 6 ), the dorsal, cranial ( Fig. 6 ) and pronotal ( Fig. 7 ) punctures are also deeper and coarser. The scutellum of L. telnovi is subquadrate (relatively more shield-shaped and distally rounded in L punctata ).

Etymology. The specific epithet, punctata , is formed from the Latin root “ punctat- ” meaning “marked with pricks or punctures.” It was chosen in reference to the strongly, densely, coarsely punctate dorsal surface sculpturing of the head, pronotum, and elytra exhibited by L. punctata .
