Young, Daniel K., 2011, Eight new species of Lemodes (Lagriomorpha) (Coleoptera: Anthicidae: Lemodinae) from Indonesian New Guinea, with a revised key to the species, Zootaxa 2824, pp. 1-20 : 7-8

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 1 st segment amber to coppery-orange, distal bulb of 1 st 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 2 X 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, 2.5 X 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 6 th ventrite (= 8 th 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.
