Lemodes (Lagriomorpha) rugosa , NEW SPECIES

( Figs. 8–10 )

Description. Length 4.3 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 male (Dorsal habitus: Fig. 8 ). Head and mouthparts rusty orange–brown; mandibles rufopiceous, at least in part. Dorsal surface of head ( Fig. 9 ) confusedly, deeply, densely, coarsely punctate, lateral and ventral aspects with sculpturing less coarse and deep; cranial neck coarsely, closely punctate. Compound eyes small, somewhat coarsely-faceted, slightly protruding. Tempora well-developed, approximately 3/4 the dorso-longitudinal length of compound eye, broadly rounded, but not produced, posteriorly. Antennae with segments 1–3 amber to yellowishorange, antennomeres 4–10 black, antennomere 11 creamy yellowish; antennae densely covered with stout, semierect and erect setae; antennomeres 6–10 each gradually wider distally, 7–10 most conspicuously so; 11th antennomere 1/2 again as long as antennomere 10, bluntly, but acuminately produced distally. Terminal segment of maxillary palpus ( Fig. 9 ) but slightly expanded distally.

Thorax with pronotum ( Fig. 10 ) rusty orange-brown; thoracic venter orange to orange-brown; pronotum hourglass-shaped, widest anterad the middle, densely covered with coppery-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 coppery, yellow-orange, femora suffused with darker pigmentation; paired, dorsal tibial carinae welldeveloped; tibial spurs very short, stout; penultimate tarsomere slightly dilated, bilobed; tarsal claws simple. Elytra coppery-orange in basal 1/3, remainder metallic blue-violet except for small, coppery-orange, subapical, sutural spot, with anterior margin of dark pigmentation advancing angulately across elytra toward the suture; elytra elongate, 2.8X longer than width across sub-basal humeral area, covering abdomen, margins subparallel along much of length; elytral surface rather coarsely, densely, confusedly, moderately deeply punctate, surface between punctures punctulate. Ventral surface of abdomen unicolorous, orange.

Adult female. Unknown.

Types. Holotype (ɗ, 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)// rugosa // Young.

Distribution. As detailed above, L. rugosa is presently known solely 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 distinctly bicolored elytra of L. rugosa with coppery-orange pigmentation restricted to the basal 1/4 to 1/2 ( Fig. 8 ) is similar to L. albertisi ( Fig. 26 ), L. bicolora (Fig. 28), L. elegans ( Figs. 1–2 ), L. finisterrensis ( Fig. 29 ), L. semicoerulea ( Fig. 30), and L. sulcata ( Fig. 17 ). The small size (4.3 mm), distinctly hourglassshaped pronotum, and relatively dense, coarse dorsal punctation of the head, pronotum, and elytra will easily separate L. rugosa from these species. In terms of size and surface sculpturing, L. rugosa is similar to L. punctata and L.

telnovi . However, L. rugosa has bicolored elytra while the elytra of L. punctata and L. telnovi are unicolorous: coppery-orange ( L. telnovi : Fig. 20 ) to orange-brown ( L. punctata : Fig. 5 ).

Etymology. The dense, coarse, dorsal surface punctures of the head and pronotum suggest a nearly “wrinkled” surface. The specific epithet, rugosa , is formed from the Latin root “ rugosa- ” meaning “a wrinkle or wrinkled.”
