Yasunaga, Tomohide, Yamada, Kazutaka & Artchawakom, Taksin, 2015, First Indochinese records of the plant bug genus Hypseloecus Reuter (Hemiptera: Heteroptera: Miridae: Phylinae: Pilophorini), with descriptions of eight new species from Thailand, Zootaxa 3925 (1), pp. 75-93 : 82-83

Hypseloecus katrinae sp. nov.

( Figs. 2 D, 4, 5–7)

Diagnosis. Externally very similar to the preceding species, but this new species can be distinguished by its carmine basic coloration; different color pattern of coxae ( Fig. 6 , Table 1 ); and widely reddish femora. The dorsal scalelike setae of all available specimens were probably rubbed off after capture.

Description. Male. COLORATION AND VESTITURE: Body generally carmine or reddish brown. Head reddish maroon, rather shining, with yellow lateral margins along eyes. Antenna uniformly pale or yellowish brown, slender; apex of segment I sometimes tinged with red; segments III and IV dark brown; the former with whitish extreme base. Labium shiny reddish brown. Pronotum carmine, usually widely infuscate; scutellum pale reddish maroon; pleura as in Fig. 6 ; ostiolar peritreme yellowish white. Hemelytron carmine with a broad dark stripe each on corium and clavus; membrane grayish brown, with pale reddish veins and irregular, pale, semitransparent portion at middle. Coxae as in Table 1 . All femora reddish brown, each speckled with pale maculae; all tibiae with rather clear, reddish brown annulations; protibia with an orange-red stripe anteriorly. Abdomen reddish brown or darker. STRUCTURE: As in generic description (see Schuh & Menard, 2011). Genitalia ( Fig. 4 ): Right paramere bulbous. Endosoma J-shaped, long, slender, with a bifurcate process at apical 1/ 3 portion. Female. Similar coloration and structure to male.

Measurements. ♂/♀: Total body length 2.0−2.2/ 2.3−2.5; length from apex of clypeus to cuneal fracture 1.71−1.73/ 1.88−1.90; width of head across eyes 0.85−0.87/ 0.91−0.93; head height 0.52−0.57/ 0.56−0.57; width of vertex 0.46−0.47/ 0.48−0.50; lengths of antennal segments I −IV 0.19−0.20, 0.68−0.70, 0.36−0.38, 0.48−0.50/ 0.20−0.21, 0.69−0.75, 0.38−0.40, 0.48−0.50; basal width of pronotum 0.99−1.00/ 1.05−1.08; maximum width across hemelytron 1.20−1.22/ 1.38−1.43; and length of metatibia 1.14−1.17/ 1.21−1.26.

Etymology. Named after Katrina Menard who greatly contributed to clarification of our knowledge of Hypseloecus , and also supported the present study.

Biology. All available specimens were collected from Scurrula species growing from Homonoia riparia Lour. Holotype. ♂, THAILAND: Nakhon Nayok: Sarika near Sarika Waterfall, 14˚18'32”N 101˚15'20”E ~ 14˚18'09”N 101˚15'38”E, on Scurrula sp., 22 Mar 2010, T. Yasunaga, K. Yamada (AMNH_PBI 00380233) (DOA). Paratypes. THAILAND: 9♂ 5♀, same data as for holotype (AMNH_PBI 00380234–00380242) (AMNH, TYCN).
