description: Lemodes (Lagriomorpha) schawalleri, NEW SPECIES
(Figs. 11–13)
Description. Length 8.2-9.0 mm (n=4). Dorsal and ventral surfaces, legs, and antennae moderately densely covered with short, mostly retrorsely decumbent setae, dorsum and elytra also with a few, longer, semierect to erect setae.
Adult female (Dorsal habitus: Fig. 11). Head and mouthparts coppery-orange; mandibles rufopiceous, at least in part. Dorsal surface of head (Fig. 12) confusedly, shallowly, moderately coarsely punctate, lateral and ventral aspects with punctures less coarse, cranial neck more coarsely punctate. Compound eyes small, finely-faceted, scarcely protruding. Tempora well-developed, approximately 1/3 again as long as the dorso-longitudinal length of compound eye, broadly rounded, but not produced, posteriorly. Antennae with basal portion of 1st segment amber to coppery-orange, distal bulb of 1st antennomere rufopiceous to black, antennomeres 2–9 black, antennomeres 10– 11 creamy yellowish; antennae densely covered with stout, semierect and erect setae, the latter scattered along length of terminal antennomere but limited to subapical aspects of remaining antennomeres. Terminal segment of maxillary palpus (Fig.12) somewhat expanded apically, weakly securiform, apical width a little more than 2X basal width. Thorax with pronotum (Fig. 13) coppery-orange; ventral surfaces of thorax orangish; pronotum hourglassshaped, slightly wider anterad the middle, densely covered with coppery-orange setae, coarsely, punctate with surface finely punctate between the larger, circular punctures; prothoracic coxal cavities widely open externally; scutellum coppery-orange, subquadrate, slightly convex, finely punctate, densely clothed in retrorsely decumbent, coppery-orange setae; mesosternum, metasternum and mesothoracic episterna with scattered, large, shallow punctures; mesothoracic episterna meeting anteromesad the mesosternum. Legs coppery-orange, tarsi slightly darker; paired, dorsal tibial carinae scarcely evident and proximally, only; tibial spurs short, stout; penultimate tarsomere slightly dilated, bilobed; tarsal claws simple. Elytra coppery-orange in basal and distal quarters, metallic blue-violet to metallic blue-green in middle half, with anterior margin of dark pigmentation nearly straight across elytra; elytra elongate, 2.5X longer than width across sub-basal humeral area, covering abdomen, margins subparallel along much of length; elytral surface rather coarsely, shallowly, confusedly punctate, surface between punctures smooth to sparsely punctulate. Metathoracic wings fully developed. Ventral surface of abdomen unicolorous, orange; abdomen with apical margin of 6th ventrite (= 8th sternite) entire.
Adult male. Unknown.

Distribution. As detailed above, L. schawalleri is presently known only from the type locality, presumably 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. Both L. schawalleri (Fig. 11) and L. securiforma (Fig. 14) have a similar metallic blue-violet to metallic blue-green elytral vitta. The terminal maxillary palpomere is weakly securiform in L. schawalleri (Fig. 12) and strongly so in L. securiforma (Fig., 15). Pronotal shape (hourglass-shaped in L. schawalleri, Fig. 13, campanulate in L. securiforma, Fig. 16), and abdominal color (orangish in L. schawalleri and black in the case of L. securiforma) also serve to easily distinguish the two species.
Within the subgenus Lagriomorpha, a somewhat similar elytral color pattern is demonstrated by Lemodes isatabua Telnov (Fig. 31), presently known solely from the Solomon Islands. Among other features, the tibial carinae, well-developed in L. isatabua (Fig. 32) and poorly so in L. schawalleri, readily separate the two species.
Etymology. The specific epithet, schawalleri, is a patronym based on the family name, “Schawaller.” I am pleased to name this species in honor of fellow coleopterist, Dr. Wolfgang Schawaller, Staatliches Museum für Naturkunde, Stuttgart, Germany.
