Identification
Huang and Zhong (2023) - This species is similar to Aphaenogaster exasperata, but in this new species, sides of pronotum longitudinally rugose, mesopleura mostly smooth, dorsum of propodeum smooth, propodeal spines about 1.2 times as long as its basal width, and body bicolored; while in A. exasperata, sides of pronotum smooth and shiny, mesopleura and metapleura finely reticulate, dorsum of propodeum with transverse rugae, and body unicolored.

Worker
Holotype TL 5.8, HL 1.27, HW 1.00, CI 79, SL 1.56, SI 156, ED 0.23, PW0.76, WL 1.89, PL 0.57, PH 0.34, DPW 0.26, PPL 0.42, PPH 0.37, PPW 0.36. Paratype workers (n = 5). TL 5.6–5.9 (5.7), HL 1.12–1.22 (1.17), HW 0.94–1.01 (0.98), CI 82–84 (83), SL 1.41–1.52 (1.48), SI 149–157 (152), ED 0.20–0.23 (0.21), PW 0.71–0.76 (0.73), WL 1.76–1.87 (1.81), PL 0.46–0.56 (0.52), PH 0.29–0.35 (0.32), DPW 0.24–0.27 (0.26), PPL 0.41–0.43 (0.42), PPH 0.32–0.37 (0.36), PPW 0.33–0.38 (0.36); mean values in parentheses.
In full-face view, head nearly rectangular and weakly elongate posteriorly, longer than broad, posterior margin straight, posterior corners broadly rounded, lateral margins moderately convex. Mandibles triangular, masticatory margin with three apical teeth followed by five small denticles. Dorsum of clypeus weakly convex, anterior margin moderately convex. Frontal carinae relatively short, reaching to eye level. Frontal lobes relatively large and suberect, concealing half of antennal socket. Antennae long, 12-segmented, apex of scape surpassing posterior head margin by 1/3 of its length, flagella filiform, antennal club 4-segmented. Eyes convex, located at midpoint of lateral head margin and occupying 1/6 of lateral margin.
In lateral view head weakly elongate and narrowing posteriorly. Promesonotum high, dorsum of pronotum weakly convex, promesonotal suture slightly impressed. Dorsum of mesonotum nearly straight and sloping down posteriorly, anterodorsal corner convex and bluntly angled. Metanotal groove deeply impressed. Propodeum low, dorsum straight and horizontal, propodeal spines short and acute, posterodorsally pointing, slightly longer than its basal width; declivity moderately concave, about half length of dorsum; propodeal lobes small and rounded apically; propodeal spiracle high on the side, close to dorsal margin. Anterior peduncle about as long as petiolar node; petiolar node roughly conical and erect, dorsum narrowly rounded, anterior and posterior margins nearly straight; ventral margin of petiole weakly concave. Postpetiole slightly higher than petiole, the node roughly triangular and slightly inclined posteriorly, dorsum narrowly rounded, anterior margin gently sloping, posterior margin steeply sloping, ventral margin weakly concave. Gaster nearly elliptical.
In dorsal view, pronotum broadest, lateral margins moderately convex, humeral corners broadly rounded. Promesonotal suture distinct. Mesothorax significantly constricting and narrow, mesonotum roughly triangular and narrowing posteriorly. Metanotal groove distinctly impressed. Propodeum nearly trapezoidal and widening posteriorly, lateral margins almost straight; propodeal spines acute, posterolaterally pointing. Petiolar peduncle narrower than the node, the node roughly elliptical. Postpetiole about 1.4 times as wide as petiole, distinctly widening posteriorly and roughly trapezoidal, lateral margins almost straight, posterolateral corners bluntly angled. Gaster oval.
Mandibles longitudinally striated. Head loosely reticulate, interface smooth. Mesosoma longitudinally rugose, longitudinal central strip of promesonotum, most part of mesopleura, most part of metapleural and dorsum of propodeum smooth and shiny. Petiole, postpetiole and gaster smooth and shiny. Body dorsum with abundant suberect to subdecumbent hairs and abundant decumbent short pubescence. Scapes with dense decumbent hairs and dense depressing pubescence, tibiae with dense depressing pubescence. Body color brownish red, head and gaster black, antennae blackish brown.
Paratypes same as holotype, but sometimes with shallower transverse rugose sculpture on pronotum, more smooth and shining; with narrower and longer propodeal spines; and with smaller body.
Type Material
- Holotype. Worker, China, Yunnan, Lijiang City, Yongsheng County, Huangniaba Baobao Mountain, 26°54′14″N, 100°30′06″E, 3000 m alt., 20-V-2022, Yuhua GU leg., KIZ0132774 (KIZ).
- Paratypes. 5 workers, with same data as holotype, KIZ0132775, KIZ0132776, KIZ0132777, KIZ0132778, KIZ0132779 (KIZ).
Etymology
The Latin specific epithet “bicolor" is composed of “bi-” (= twice) + “color” and refers to the bicolored body.
