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
