Figs. 1, 2, 3A–B, 4A–C

Holotype. China: Male, Yunnan, Er’yuan, Niuguidan Village, 5.VII.2021, Libin Ma & Wei Yuan coll. Paratypes. 4 males and 4 females, the same data as the holotype; 2 males & 1 female, Yunnan, Lijiang, Gucheng County, Sheshan Park, 5.VIII.2021, Zhixin He & Ning Wang coll. (SNNU).

Description. Male (Figs. 2A and 3A). Body size small. Head small and pubescent, slightly wider than the anterior margin of pronotum. Frontal rostrum twice broader than antennal scape. Eyes large. Apical three joints of maxillary palpi distinctly elongated and the 5th joint apically truncated and shaped as horseshoe shaped. Pronotum transverse, both anterior and posterior margins straight and the posterior wider than the anterior. Tegmen short; dorsal field bearing four longitudinal veins and lateral field with four Sc branches. Tympana absent. Hind tibia bears three dorsal external spurs and four internal spurs, and apical spurs comprising two outside and three inside.

Genitalia (Figs. 3A–C). Epiphallus relatively short (confined to the basal half of the genitalia complex) and ectoparamere very large (almost similar to epiphallus). Median part of the epiphallus shaped as a bridge and very thin. Ectoparameres clip-shaped (viewed laterally) with an upper branch (large, curved, proximally expanded and apically acute) and lower branch (short and nearly straight).

Female (Figs. 2B, 3B). Resemble male. Body size slightly larger than male. Ovipositor needle-like and slightly shorter than cercus.

Coloration. Body blackish brown. Four brown longitudinal stripes at the dorsal area of the head. Legs dark brown.

Measurements. Male (n=7). BL 4.22±1.29, PL 1.08±0.24, TL 1.27±0.83, HFL 2.79±0.62; Female (n=5). BL 4.45±1.10, PL 1.03±0.14, TL 1.03±0.56, OL 2.42±0.43.

Etymology. The name refers to the species’ short tegmen.

Distribution (Fig. 1). China (Yunnan).

Remarks. This species is similar to Homonemobius curifolis Zhang et al., 2020 in color,but differin the shape of epiphallus. Of the known species, H. curifolis has a short and thick clip-like ectoparamere, which this structure is long and thin on H. brevipennis sp. nov. This new species also resembles Homonemobius amare He & Ma, 2021. The differences are: shorter tegmen, and more acute lower branch of the ectoparameres. It differs from Homonemobius nigrus Li et al., 2010 in ectoparameres (bifurcated vs. not bifurcated), and differs from H. monomorphus in coloration of body (dark brown vs. yellowish brown) and tegmen’s length (reached the 3 rd vs. 6 th segment of abdomen).
