Holotype: CHINA: f’, labeled “China: Fujian Province (ự×省), Sanming City (三m市), Sha County (沙县), Fenggang (-Hĸae), Dongtianyan Reservoir (洞g岩水库), right area of the dam, 26º23’25.3718” N, 117º4351.5750” E, in nest of Nasutitermes sp. , 1 m under ground, Tai-Ping Huang, Shui-Ming Yin, Guo-Chao Yin, Jin-Wei Qiu, Zhao Huang, Quan-Ming Feng, Cui-Lin Lei, Xue-You He, Hai-Tian Song leg.” ( MHBU) ; Paratypes: CHINA: 2 ♀ ♀, same label data as the holotype (1 ♀, MYNU; 1 f, FAFS) .

Diagnosis. As for the genus (vide supra).

Description. Body ( Fig. 1A View FIGURE 1 ) reddish brown, surface shiny and finely covered with short thin hairs.

Head ( Figs 1B–C View FIGURE 1 ) hypognathous, surface covered with sparse, differently sized round punctures and short thin setae. Compound eyes comparatively large, nephroid, well separated on frons, not contacting each other medially, width between compound eyes on frons about 5× as long as a single ommatidial diameter. Area below compound eyes with large, irregularly spaced punctures. Epistoma relatively large, surface finely covered with large punctures and short setae, apical margin slightly curved medially. Apical margin of labrum nearly straight, surface finely covered with short setae and much longer setae on apical quarter. Mandibles ( Fig. 1C View FIGURE 1 ) apically bifid, apices acute. Antennal tubercles of frons weakly raised. Antenna ( Fig. 2A View FIGURE 2 ) with 11 antennomeres, scape expanded near apex; pedicel globular, about as long as wide; antennomere III longer than wide, slightly expanded apically; antennomeres IV–VI similar, nearly trapezoidal, widest apically; antennomeres VII–X similar, apically rounded; antennomere XI oblong. Relative length of antennomeres II–XI (mm): 0.13: 0.21: 0.21:0.19: 0.20: 0.22: 0.22: 0.22: 0.23: 0.32; relative width of antennomeres II–XI (mm): 0.12: 0.13: 0.17: 0.19: 0.19: 0.18: 0.18: 0.17: 0.17: 0.16.

Pronotum ( Fig. 2B View FIGURE 2 ) slightly wider than long, widest medially, disc strongly convex, surface finely covered with large punctures and short erect setae; anterior margin slightly rounded, lateral margins flexuose, posterior margin distinctly rounded; anterior and posterior angles distinctly raised, with anterior angles rounded and posterior angles acutely projecting. Prosternum ( Fig. 2C View FIGURE 2 ) distinctly raised before procoxae; apex of prosternal process ( Fig. 2C View FIGURE 2 ) nearly triangular. Surface of prothoracic hypomera covered with large punctures and sparse short setae.

Mesoscutellum semicircular, covered with sparse small punctures and short setae.

Elytra nearly parallel-sided, about twice as long as wide, surface shiny and finely covered with short, thin, erect setae; each elytron with nine distinct intervals, only interval I extending from elytral base to apex, other intervals not connected at elytral apex; intervals IV–VI distinctly shorter than others, interval IX not visible in dorsal view (only in oblique dorsal or profile); punctures of interval striae large and round, space between punctures on average wider than a puncture diameter.

Metaventrite ( Fig. 2D View FIGURE 2 ) finely covered with short thin setae and small punctures; mediolongitudinal sulcus distinct, extending from anterior margin to ca. 2/3 of metaventrite length; surface of mesoventrite ( Fig. 2D View FIGURE 2 ) covered with sparse small punctures and short thin setae, mesoventral intercoxal process connected to metaventrite. Mesepimeron covered with sparse small punctures and thin setae, mesepimeral line shallow. Metepimeron slender, surface covered with sparse punctures and short thin setae.

Profemur ( Fig. 3A View FIGURE 3 ) strongly expanded in apical 1/4 and armed with a triangular tooth on inner surface. Protibia ( Fig. 3B View FIGURE 3 ) simple, inner surface modified with dense short setae, apex with two small teeth. Meso- ( Fig. 3C View FIGURE 3 ) and metafemora ( Fig. 3E View FIGURE 3 ) slightly expanded distad midlength. Meso- ( Fig. 3D View FIGURE 3 ) and metatibiae ( Fig. 3F View FIGURE 3 ) slightly narrowed on inner surface in apical half.

Abdomen ( Fig. 2E View FIGURE 2 ) finely covered with large punctures and short setae, anterior margin of abdominal ventrites III and IV distinctly concave, ventrite V longest, about as long as combined lengths of ventrites III and IV. Inner sternite VIII ( Fig. 3G View FIGURE 3 ) semicircular, deeply emarginate on posterior margin and covered with dense long setae. Spiculum ventrale ( Fig. 3G View FIGURE 3 ) tortuous, thin and strongly elongate. Paraproct ( Fig. 3H View FIGURE 3 ) thin and long, baculi sclerotized and curved. Ovipositor ( Figs 3H–I View FIGURE 3 ) weakly sclerotized, apex ( Figs 3H–I View FIGURE 3 ) with several setae of variable lengths. Coxites I and II subequal in length, with sclerotized lateral margins; lateral margins curved on coxite I and nearly straight on coxite II; coxite III slighter longer than combined lengths of coxites I and II, and with only anterior part of lateral margin sclerotized; coxite IV about as long as coxite III, covered with several setae of variable lengths. Styli ( Fig. 3I View FIGURE 3 ) sclerotized, apex with several setae of variable lengths.

Measurements. BL 4.57–4.69 mm, HW 0.80–0.88 mm, PL 1.20–1.23 mm, PW 1.35–1.43 mm, EL 3.37–3.46 mm, EW 2.03–2.05 mm.

Male, unknown.

Distribution. China: Fujian Province.

Biology. All individuals of the new species were collected from a healthy nest of the termite genus Nasutitermes ( Figs 4–5 View FIGURE 4 View FIGURE 5 ), together with a species of Coenochilus Schaum, 1841 ( Scarabaeidae : Cetoniinae ) and a species of Leiodinae Fleming, 1821 (Leiodidae) ( Fig. 4A View FIGURE 4 ).

Etymology. The species epithet honors Mr. Tai-Ping Huang (Fujian, China), ( Fig. 5B View FIGURE 5 left), who is in charge of Fuzhou Malt Termite Control Co., Ltd., and who guided us in the field and collected the host termite nest. We are grateful for his support and collegial collaboration in the field.
