Holotype.
China: "CHINA, Yunnan Province, Fugong Co., Lishadi town, Shibali village, roadside, 27.16520°N, 98.77980°E / 2530 m, 2004.5.5, night, Liang H-B, Li X-Y, coll., California Academy &IOZ., Chinese Acad Sci / IOZ(E) 1890507 / Holotype / Gastrocentrum gaoligongense sp. nov. Det. Yang G.Y. 2020" (IZAS, male) (Fig. 7 View Figures 1–9 ). Paratypes. CHINA: Yunnan, Gongshan, Menggaguo, 2800 m, Light, 2016.VII.8, Yu-Tang Wang leg. (CCCC, 1 male, 1 female); same but 2016.VI.30 (CCCC, 1 male); same but 2016.VI.24 (CCCC, 1 female).
Diagnosis.
The new species differs from G. zayuense sp. nov. by: elytra with a pair of wedge-shaped protuberance on inner surface; tegmen apices bulged on ventral surface (Fig. 19b View Figure 19 ); female bursa copulatrix not differentiated, merely a swollen continuation of the vagina, distal part of spermathecal capsule, long and slender, length/width ratio> 5 (Fig. 22E View Figure 22 ).
Description.
General appearance: length 13-19 mm, slenderer than all the other species, dark brown. Head: including eyes slightly broader than pronotum; eyes moderately large, distance between eyes slightly longer than the transverse diameter of eye; gular suture slightly convergent in anterior; female antennae broadly expanded laterally from 7th antennomere onwards, while male 7th antennomere less expanded (Fig. 19H View Figure 19 ); vertex and frons with dense and somewhat coarse punctations, postgenae rugose. Pronotum: oblong, length/width ratio ca. 1.6, constricted posteriorly, faintly constricted anteriorly; surface finely and densely punctate, clothed with long, yellow hairs. Elytra: oblong, sides subparallel in basal half and weekly widened in apical half, length/width ratio ca. 2.6, vested with light yellow setae; wedge-shaped protuberance present on inner surface; elytra with very few asetiferous punctations, number of PAP on each elytron ranged from 2~39 (n = 5), present on elytral basal disc in five rows in maximum, AAP absent (Fig. 10E View Figure 10 ). Legs: outer apex of protibia not extending outwards. Abdomen: intercoxal process of the first ventrite not grooved longitudinally; metacoxal abdominal depressions weekly ridged in anterior margin. Male genitalia: pygidium with posterior margin rounded (Fig. 19F View Figure 19 ); sixth ventrite arciform, width twice length, posterior margin rounded, central membranous region small, extending from the anterior margin, not reaching half-length of ventrite (Fig. 19G View Figure 19 ); tegmen tubiform, length ratio of phallobasic apodeme to phallobase ca. 1: 3.2 (Fig. 19A-C View Figure 19 ); parameres hooked, ventral surface of the hook bulged in lateral view (Fig. 19b View Figure 19 ); interphallic plate shorter than half length of phallus (Fig. 19D View Figure 19 ); phallus apex knot-like, slightly longer than wide (Fig. 19D, d View Figure 19 ). Female reproductive organs: pygidium slightly broader than long, posterior margin rounded; sixth ventrite widely trapezoidal, 2.5 × broader than long, rounded posteriorly, central membranous region broad, apical accessory membranous region absent; bursa copulatrix unclearly defined, merely swollen continuation of vagina; spermathecal gland with a top tail of medium length; spermathecal duct long and slender; spermathecal capsule feebly bifurcate in sub-apex; distal part of spermathecal capsule long and slender, length/width ratio> 5 (Fig. 22E View Figure 22 ).
Distribution.
China (Yunnan).
Etymology.
