Lemodes (Lagriomorpha) enarotadi , new species

( Figs. 4–6 )

Description. Length 5.8 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. 4 ). Head and mouthparts coppery-orange; mandibles rufopiceous, at least in part. Dorsal surface of head ( Fig. 5 ) confusedly, densely but shallowly punctate, lateral and ventral aspects with punctures less coarse, cranial neck more coarsely punctate. Compound eyes small, fine-faceted, slightly protruding. Tempora (measured from cranial neck constriction anteriorly to posterior rim of compound eye) 0.79X dorso-longitudinal length of compound eye. Antennae with antennomere 1 yellowish-orange, antennomeres 2–3 rufopiceous, 4–10 largely black, antennomere 11 creamy yellowish-orange; antennae densely covered with stout, semierect and erect setae; antennomeres 4–10 each gradually wider distally; 5–10 most conspicuously so; 11th antennomere 1/2 again as long as antennomere 10, bluntly tapering, distally. Terminal segment of maxillary palpus somewhat expanded. Visible dorsal and ventral surfaces of thorax yellow-orange; pronotum ( Fig. 6 ) campanulate, widest anterad the middle, densely covered with yellowish to coppery-orange setae, coarsely but shallowly punctate with surface finely punctulate between the larger punctures; prothoracic coxal cavities widely open externally; scutellum flat, distally rounded, shallowly punctate, densely clothed in retrorsely decumbent, yellowish-orange to orange setae; mesosternum, metasternum and mesothoracic episterna with scattered, large, shallow punctures; mesothoracic episterna meeting anteromesad the mesosternum. Legs yellowish-orange ( Fig. 4 ); paired, dorsal tibial carinae virtually absent; tibial spurs short, stout; penultimate tarsomere slightly dilated, bilobed; tarsal claws simple. Elytra cinnamoneous-orange in basal quarter, yellowish-orange in distal quarter, remainder metallic blue-violet forming a broad, medial band ( Fig. 4 ); elytra elongate, 2.6X longer than width across sub-basal humeral area, covering abdomen, margins subparallel along much of length, slightly wider in distal 3/4; elytral surface densely, but shallowly, confusedly punctate, surface between punctures finely punctulate. Metathoracic wings fully developed. Ventral surface of abdomen yellowish-orange.

Distribution. As detailed above, L. enarotadi is presently known only from the type locality, “ Enarotadi , in western Papua Province, Indonesian, New Guinea ”. In a species page for Miridae [http://www.discoverlife.org/mp/ 20l?id=AMNH_PBI00321088], Schuh listed the geo-coordinates as, - 3.91669° S, 136.35017° E. These coordinates are located in Paniai Lake, just off the shore of Enarotadi .

Diagnosis. The distinctly bicolored elytra of L. enarotadi with coppery-orange to yellowish-orange pigmentation restricted to the basal and distal quarters, and with a broad, medial, transverse metallic blue-violet fascia ( Fig. 4 ) are similar to those of Lemodes isatabua Telnov , Lemodes schawalleri Young , and Lemodes securiforma Young.

In L. schawalleri antennomeres 1–9 are largely black, 10–11 are creamy yellowish-orange, and the elytra are more coarsely and deeply punctate ( Fig. 17 ). Antennomeres 1–4 and 11 are lightly pigmented in L. securiforma the terminal maxillary palpomere is strongly securiform ( Fig. 18 ), and the abdominal venter is also black. From L. isatabua , L. enarotadi can easily be separated by the fairly straight anterior margin of the blue-violet elytral vitta (anterior margin abruptly receding along the suture in L. isatabua : Fig. 19), and by the paired, dorsal tibial carinae (well-developed in L. isatabua and virtually absent in L. enarotadi ).

Etymology. The specific epithet, enarotadi , is a direct reference to the type locality, the geographical place name, Enarotadi .
