Oh, Minsuk, Yasunaga, Tomohide & Lee, Seunghwan, 2015, First record of the plant bug genus Paramiridius Miyamoto & Yasunaga (Heteroptera, Miridae, Mirinae) from Indochina, with descriptions of two new species from Laos, ZooKeys 546, pp. 51-59 : 52-53

Taxon classification Animalia Hemiptera Miridae

Paramiridius indochinensis sp. n. Figs 1, 2, 3, 4

Diagnosis.

Recognized by the characters given in the key, and the tapered hypophysis of the right paramere (Fig. 2), the developed, curved endosomal spicule (Fig. 3), and the wide, squared interramal lobe (Fig. 2). Most closely related to Paramiridius tigrinus , from which this new species can be distinguished by the preceeding diagnostic characters.

Description.

Coloration: Body generally yellow; dorsum with black-striped patterns (Fig. 1). Head yellow, medially black; eye margin black. Antenna almost entirely dark brown without pale portions. Labium shiny yellowish brown; segment IV darkened. Pronotum yellow, with three pairs of black stripes (each pair fused together posteriorly); and with narrowly yellow posterior margin. Mesoscutum wholly black. Scutellum medially black; lateral part and apex yellow. Hemelytron widely blackish brown, with three pairs of yellow stripes each along claval vein, claval suture and R+M vein (Fig. 1); posterior half of clavus, anterior quarter to half part of corium, anterior two-third of embolium and entire cuneus yellow. Coxa pale yellow; leg yellow; each femur with more or less darkened apical part; each tibia yellow, with a dark, subbasal annulation and darkened apex; all tarsi brown.

Structure and vestiture: As in generic description provided by Miyamoto and Yasunaga (1992). Body elongate, parallel-sided; dorsal vestiture generally short, simple, and only sparsely distributed. Head vertical; vertex apparently wider than an eye in dorsal view. Labium reaching middle part of metacoxa.

Male genitalia (Figs 2, 3): Similar to type species of the genus, Paramiridius tigrinus . Left paramere with a sharp, triangular subbasal protuberance; hypophysis of right paramere developed, claw-like (Fig. 2). Endosomal spicule broad, curved at basal one third, somewhat flattened apically (Fig. 3).

Female genitalia (Figs 2, 4): Bursa copulatrix as in Fig. 4; dorsal labiate plate ventro-medially produced. Interramal lobe wide and squared; interramal sclerite narrowed (Fig. 2).

Measurements ♂/♀: Total body length 5.88/ 6.42-7.02; head width across eyes 1.09/ 1.13-1.17; vertex width 0.49/ 0.50-0.52; lengths of antennal segment I–IV 1.25, 3.43, 1.32,?/ 1.24-1.26, 2.67-2.81, 1.71-1.76, 0.42-0.44; labial length 2.10/ 2.18-2.34; mesal pronotal length including collar 1.23/ 1.29-1.40; basal pronotal width 1.96/ 2.09-2.25; width across hemelytron 2.06/ 2.21-2.43; cuneal length 1.13/ 1.18-1.22; cuneal width 0.72/ 0.81-0.92; lengths of metafemur, tibia and tarsus 3.06, 4.21, 0.75/ 3.08-3.19, 4.38-4.56, 0.73-0.77.
