Yasunaga, Tomohide & Duwal, Ram Keshari, 2017, A new species of the phyline plant bug genus Chimairacoris from central Sulawesi, Indonesia (Hemiptera: Heteroptera: Miridae: Phylinae), Zootaxa 4282 (3), pp. 593-599 : 595-597

Chimairacoris prodigiosus Yasunaga & Duwal , n. sp.

( Figs. 1 A–G, 2A–F, 3B–E)

Diagnosis. Distinguished readily from other phyline including its congener C. lakshmiae , by its noticeably elongate large body, longer and more slender antenna; smooth pro- and metafemora; and greatly elongate phallotheca and endosoma. Principal differences between these two congeners are summarized in Table 1.

Description. Male. Surface and vestiture: Body surface, including head and thoracic pleura, weakly shining, with densely distributed, short, reclining setae; tibial spines short, sparse; male genital segment with uniformly distributed, long, stiff setae. Coloration: Body, including antenna and legs, fuscous, almost concolorous. Labium shiny castaneous. Forewing membrane pale smoky brown, semitransparent, with brown veins. All tarsal segments brown. Structure: As summarized in Table 1. Head wider than long in dorsal view; eye small, produced laterally. Antenna linear; segments I and II somewhat thickened. Labium short, slender, not reaching apex of procoxa. Pronotum shallowly and roughly punctate, not carinate laterally; scutellum flat. Hemelytron generally flat, as wide as abdomen. All femora not thickened, without any spines; tibial spines short. Male genitalia ( Figs. 2 A–E, 3B–E): Pygophore trapezoidal, elongate; phallotheca very long, slightly longer than pygophore; endosoma with a narrow, apically pointed process; secondary gonopore thick-rimmed. Female: Unknown.

Measurements. Holotype male: Total body length 5.4; width of head across eyes 1.29; head length 0.60; width of vertex 0.76; lengths of antennal segments ĪIV 0.36, 1.14, 0.57, 0.53; mesal length of pronotum 0.95; basal width of pronotum 1.60; maximum width across hemelytron 1.77; and lengths of metafemur, tibia and tarsus 1.33, 1.50, 0.39.

Etymology. From Latin, prodigiosus (= extraordinary, strange, wonderful), referring to its strange habitus like deraeocorine and unexpected occurrence in Sulawesi; an adjective.

Biology. Unknown; a single male was collected by sweep-netting of broadleaf or herb microhabitat in a tropical rain forest.

Distribution. Indonesia (Central Sulawesi).

Holotype: Male, INDONESIA: Central Sulawesi, Palu–Palolo , 1°13'S, 120°03'E, sweep-netting, 25 Apr 1988, T. Yasunaga ( AMNH _PBI 00380568) ( AMNH).
