Lemodes (Lagriomorpha) triplehorni , NEW SPECIES

( Figs. 23–25 )

Description. Length 5.1–5.3 mm (n=3). Dorsal and ventral surfaces, legs, and antennae moderately covered with short, mostly semierect setae, dorsum and elytra also with a few, longer, semierect to erect setae.

Adult female (Dorsal habitus: Fig. 23 ). Head and mouthparts yellowish-brown to ferrugineous. Dorsal cranial surface ( Fig. 24 ) coarsely, nearly rugosely punctate, lateral and ventral aspects with punctures somewhat less coarse; cranial neck coarsely, closely punctate. Compound eyes reduced, somewhat coarsely-faceted, scarcely protruding. Tempora ( Fig. 24 ) well-developed, approximately 5/6 the dorso-longitudinal length of compound eye, acutely produced posteriorly. Antennae with segments 1–2 rufotestaceous, antennomeres 3–5 gradually darker, antennomere 5 rufopiceous, antennomeres 6–10 black, antennomere 11 piceous to black in basal 1/2, apex creamy yellowish; antennae densely covered with stout, semierect and erect setae, the latter scattered along length of terminal antennomere but more confined to subapical aspects of remaining antennomeres; antennomeres 6–10 subclavate; 11th antennomere slightly less than 1/2 again as long as antennomere 10, bluntly, but acuminately produced distally. Terminal maxillary palpomere somewhat expanded apically, broadly rounded, apical width about 2X basal width. Thorax yellowish-brown to ferrugineous; pronotum ( Fig. 25 ) strongly hourglass-shaped, widest anterad the middle, covered with ferrugineous setae, coarsely, closely, confusedly punctate, with broad, shallow, mesal depression; prothoracic coxal cavities widely open externally; scutellum yellowish-brown to ferrugineous, quadrate, densely clothed in retrorse, yellowish setae; mesosternum, metasternum and mesothoracic episterna with scattered, large, shallow punctures; mesothoracic episterna meeting anteromesad the mesosternum. Legs yellowish-brown to ferrugineous, paired, dorsal tibial carinae clearly evident, tibial spurs exceedingly short (very difficult to see); penultimate tarsomere slightly dilated, bilobed; tarsal claws simple. Elytra piceous to black with distinct greenish-purple to purplish-blue hue, dense patches of grayish-white setae forming two transverse bands: a broad, diagonally slanting band near posterior aspect of basal 1/2 and a second, narrower, preapical band; elytral apices suffused with yellowish-brown (more obvious in paratype); elytra elongate, 2.3X longer than width across sub-basal humeral area, covering abdomen, margins subparallel along much of length; elytral surface rather coarsely, confusedly punctate, surface between punctures smooth to sparsely punctulate. Metathoracic wings fully developed. Abdomen yellowish-brown to ferrugineous, ventrites often suffused with darker pigmentation; apical margin of 6th ventrite (= 8th sternite) entire.

Adult male. Unknown.

Distribution. As detailed above, L. triplehorni is presently known only from the area between the coastal city of Manokwari and the Anggi Lakes area in the Arfak Mountains, SSW of Manokwari, Province of West Papua, Indonesian New Guinea.

Diagnosis. The small size and acutely produced genae are diagnostic for three species within the subgenus: L. triplehorni ( Fig. 24 ), L. bellstedti ( Telnov 2009: Fig. 1 ) and L. jayawijaya ( Telnov 2009: Fig. 10 ). The head and pronotum, like the elytra, are metallic blue-black in L. jayawijaya ; they are orange to red-orange in L. triplehorni ( Fig. 23 ) and L. bellstedti . The legs of L. triplehorni are unicolorous, yellowish-brown; those of L. bellstedti are distinctly bicolored. The well-developed, grayish-white elytral setal bands on the mid-discal areas of the elytra of L. triplehorni are also diagnostic. The elytra of L. bellstedti have but a few, indistinct whitish setae near each middiscal lateral margin, not forming bands or defined patches.

Etymology. The specific epithet, triplehorni , is a patronym based on the family name, “Triplehorn.” I am pleased to name this species in honor of mentor, long time friend, colleague, and fellow coleopterist, Dr. Charles A. Triplehorn of The Ohio State University.
