Lemodes (Lagriomorpha) latangaiensis , new species

( Figs. 10–12 )

Description. Length 6.0 mm (n=1). Dorsal and ventral surfaces, legs, and antennae moderately densely covered with short, mostly decumbent setae, dorsum and elytra also with a few longer, semierect to erect setae.

Adult male (Dorsal habitus: Fig. 10 ). Y Head and mouthparts coppery-orange; mandibles rufopiceous, at least in part. Dorsal surface of head ( Fig. 11 ) confusedly, conspicuously, closely, coarsely punctate, lateral and ventral aspects with punctures less coarse, cranial neck coarsely punctate. Compound eyes small, somewhat coarsely faceted, slightly protruding. Tempora (measured from cranial neck constriction anteriorly to posterior rim of compound eye) 0.68X dorso-longitudinal length of compound eye. Antennae with antennomere 1 amber, antennomeres 2–4 a bit darker, 5–10 rufopiceous, antennomere 11 creamy yellowish-orange; antennae densely covered with stout, semierect and erect setae; antennomeres 5–10 each gradually wider distally; 11th antennomere nearly 2X length of 10th, tapering, bluntly acuminate distally. Terminal segment of maxillary palpus securiform. Visible dorsal and ventral surfaces of thorax coppery-orange; pronotum ( Fig. 12 ) campanulate, widest anterad the middle, densely covered with coppery-orange setae, coarsely punctate with surface finely punctate between larger punctures; prothoracic coxal cavities widely open externally; scutellum flat, quadrate, densely punctate, densely clothed in retrorsely decumbent, orange to coppery-orange setae; mesosternum, metasternum and mesothoracic episterna with scattered, large, shallow punctures; mesothoracic episterna meeting anteromesad the mesosternum. Legs yellowish-testaceous ( Fig. 10 ); paired, dorsal tibial carinae well-developed, conspicuous; tibial spurs short, stout; penultimate tarsomere slightly dilated, bilobed; tarsal claws simple. Elytra coppery-orange in basal 1/3 and distal 2/5, remainder forming medial, metallic blue-violet vitta, with anterior margin of dark pigmentation conspicuously receding along elytral sutures; elytra elongate, 2.5X longer than width across sub-basal humeral area, covering abdomen, margins subparallel along much of length, slightly wider in apical 3/5; elytral surface rather coarsely, somewhat deeply, confusedly punctate, surface between punctures finely punctulate. Metathoracic wings fully developed. Ventral surface of abdomen yellowish-amber.

Type. Holotype (3, minuten double-mounted): [First label]: [ NEW GUINEA] NEW IRELAND // Kandan// 1.I. 1960; [Second label]: W. W. Brandt// Collector//BISHOP; [Third label]: Auto-Montaged// digital image(s)// per D. K. Young; [Fourth label]: HOLOTYPE:// Lemodes // (Lagriomorpha)// latangaiensis // Young. ( BPBM).

Distribution. As detailed above, L. latangaiensis is presently known only from the type locality, Kandan along the northern coastline of New Ireland, Papua New Guinea; near

- 3.218038° S, 151.943642° E.

Diagnosis. The cinnamoneous-orange elytra with a medial, transverse, blue-violet vitta expressed by L. latangaiensis is most similar to the pattern seen in L. isatabua (Fig. 19). The head and pronotum of L. latangaiensis are more coarsely punctate than those of L. isatabua . Among other differences, antennomeres 1–3 are amber in L. isatabua (antennomeres 1–4 in L. latangaiensis ), and the metallic, blue-violet elytral vitta is visibly narrower in L. latangaiensis ( Fig. 10 ) than is the broad elytral vitta of L. isatabua (Fig. 19).

Etymology. The specific epithet, latangaiensis , is derived from the root, “ latangai ” in reference to the local, geographic name-place: Latangai Island (= New Ireland), Papua, New Guinea, in combination with the Latin “- ensis ” (= of, or belonging to).
