description: Decomia Poppius, 1915 (7 spp.)
Decomia anthophila Yasunaga & Duwal, 2015 (Figs 1 A, 4J, 5)—Laos* (Bolikhamsai), Thailand (Nakhon Nayok, Nakhon Ratchasima). Note: This decomiine bug was recently described from central Thailand, comparing with D. indochinensis Schuh as the closest sister taxon (Yasunaga & Duwal, 2015). However, D. anthophila Yasunaga and Duwal could be more easily confused with D. malayensis Schuh, from which it can be distinguished by the darkened apical 1/6–1/5 of the light brown antennal segment II; in the latter species, recorded from Malay Peninsula and possible occurrence in Indochina, the apical half of antennal segment is infuscate (Schuh, 1984).
Decomia chiangdaoensis Schuh, 1984 (Figs 1 B, 3, 4H, 5)—North, northeastern and central Thailand; Nepal. Note: This species is in most cases collected together with D. indochinensis, using UV light traps or sweeping inflorescences of broadleaf angiosperms.
Decomia indochinensis Schuh, 1984 (Figs 1 C–D, 3, 4I, 5)— Cambodia, Laos * (Xiang Khoang), North and central Thailand, Vietnam, Philippines (Visayas) and Peninsular Malaysia (Perak).
Decomia ishikawai Yasunaga, Duwal & Lee, n. sp. (Figs 3, 4 A–C, 5)—Laos (Xiang Khoang); Thailand (Chiang Mai).
Decomia nigrissima Yasunaga, 2010 (Figs 1 E, 4D–E, 5)— Thailand (Nakhon Ratchasima). Note: The male is for the first time documented here, and is basically similar in overall appearance to the female described by Yasunaga (2010). The male genitalia are rather modified, with the left paramere narrow, not distinctly sprayedout (Fig. 4 D) and endosoma significantly slender (Fig. 4 E); total body length 2.00; width of head across eyes 0.64; lengths of antennal segments I–IV 0.11, 0.49, 0.21, 0.21; basal width of pronotum 0.86; maximum width across hemelytron 1.01; and lengths of metafemur, tibia and tarsus 0.75, 1.03, 0.37. This species was described only on a female holotype; recent field investigation at the type locality produced two more materials: Nakhon Ratchasima, Wang Nam Khieo, Sakaerat Environmental Research Station, N14.507530, E101.927640, UV light trap, 12–14 Dec 2015, T. Yasunaga, 1 male, 1 female (TYCN).
Decomia schuhi Yasunaga, 2010 (Figs 1 F, 4F, 5)—Thailand (Nakhon Ratchasima).
Decomia taksini Yasunaga, 2010 (Figs 1 G, 4G, 5)—Thailand (Nakhon Nayok, Nakhon Ratchasima).
Decomioides Schuh, 1984 (3 spp.)
Decomioides kazutakai Yasunaga, 2010 (Fig. 2 C)—Thailand (Nakhon Nayok & Nakhon Ratchasima). Note: All three congeners listed here are known to be associated with Macaranga spp. (Euphorbiaceae).
Decomioides schneirlai Schuh, 1984 (Fig. 2 A)— Thailand (Nakhon Ratchasima), China (Hong Kong), Japan (Ryukyus), Papua New Guinea, Philippines, Taiwan.
Decomioides verecundus Yasunaga, 2010 (Fig. 2 B)—Thailand (Nakhon Nayok & Nakhon Ratchasima).
Malaysiamiris Schuh, 1984 (2 spp.)
Malaysiamiris nigrescens Yasunaga & Duwal, 2015 (Fig. 2 D)— Thailand (Nakhon Ratchasima). Malaysiamiris rufobadius Yasunaga, 2010 (Fig. 2 E) — Thailand (Nakhon Ratchasima).
Rubrocuneocoris Schuh, 1984 (2 spp.)
Rubrocuneocoris anandros Yasunaga & Duwal, 2015 (Fig. 2 F)—Thailand (Nakhon Ratchasima).
Rubrocuneocoris nigriceps Duwal, Yasunaga & Lee, 2010 (Figs. 2 G; 4K–M)— Laos * (Xiang Khoang: Kham District), Nepal (Kaski, Kathmandu Valley). Note: Although a recent work (Yasunaga & Duwal, 2015) documented R. anandros from central Thailand, the present congener collected in Laos undoubtedly corresponds to R. nigriceps originally described from warm temperate zone in Nepal, on the basis of a close examination on the male genitalic structure (Fig. 4 K–M). Duwal et al. (2010) suggested its breeding host as Castanopsis sp. (Fagaceae), but the plant association in Laos remains unknown.
