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.
