Wings transparent, veins pale amber. Legs pale brown. Male. Forewing length 5.5 - 7 mm. Epiproct narrow at base and enlarged at midlength to form an apically bifid bulbous process; protruding from notch is an apically divided, slender fork-like process (the apparent extension of the ventral sclerite) which extends beyond the anterior margin of tergum 10 (Fig. 1); lateral aspect of bulbous portion of epiproct apex without obvious spine row (Fig. 3), but fine spicules occur along midventral margin of projecting mesal processes. Tergum 10 bears a sparse field of fine spinules beneath epiproct tip. Sclerite of tergum 9 strongly narrowed on midline and bearing a few long setae and patches of fine spinules. Paraproct inner lobe a short triangular sclerite (Fig. 2), outer lobe an inconspicuous slender sclerite closely appressed to mesal lobe; mesal lobe broad at apex in caudal aspect, and subdivided into two small lobes, each bearing one or two strong bristles (Fig. 2); in dorsal aspect, the apical section of paraproct mesal lobe bears a pair of apical bristles and a basal sclerotized thumb-like projection.

039D7860FFDAFFF7FEECF98BFC66DDF4.taxon	diagnosis	Diagnosis. The epiproct of this species is generally similar to that of A. gressitti which Kawai (1969) described from a Dalat, Vietnam specimen. In our specimen of A. gressitti from Thua Thien-Hue Province, the projecting apical process appears as a single, upwardly curved hook-like structure, although Kawai (1969) shows it as a pair of closely appressed processes. In addition the lateral aspect of the bulbous portion of the epiproct of A. gressitti bears a short row of fine spines. The paraprocts of A. bifurcata and A. gressitti also differ (compare Figs. 2 and 14).	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

039D7860FFDAFFF5FC07F8FBFF38DD22.taxon	diagnosis	Diagnosis. The epiproct of this species is generally similar to that of A. leigong Wang & Du in sharing the presence of a pair of strongly sclerotized, slender, spine-like lateral sclerites. That species also has a strong, anteriorly directed mesal sclerite with a subapical spine tuft which is absent in A. caoae. In addition a distinctive sclerite and a pair of spiny knobs are located on the surface of tergum 10 in A. caoae but not in A. leigong (Wang et al. 2006). Details of paraproct shape and armature also differ for the two species. The epiproct of this species is also similar to those of A. divergens, A. giay and A. viet (all described below) and several Chinese species identified in the diagnosis for A. divergens, but the specific details of the epiproct and paraprocts differ significantly among these species. Amphinemura caoae is the only one of these species in which there is a wide, toothed structure lying between the divergent and apically toothed lateral arms of the epiproct. In other species the mesal toothed structure is about as wide as the lateral arms and in some other species the mesal structure, or the lateral arms are without teeth.	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

This species was previously known from the holotype male and although there are differences in the genitalia of our specimen and the figures provided by Kawai (1969) they are in essential agreement in head and pronotal pigment pattern, dorsal and lateral epiproct shape and in having at least one very long, dark seta near the paraproct apex. Kawai shows a pair of fine, parallel processes projecting from the base of the median process of the epiproct, but in our specimen this process appears to be single. The holotype will need to be examined in order to resolve the status of our specimen. We present Figs. 13 - 15 to help in recognition of this species.	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

This species is one of the most widely distributed Asian members of the genus with populations now reported from Inner Mongolia to Hainan (Li & Yang 2008 c) and northern Vietnam. Males are easily recognized by virtue of the notched inner paraproct lobes and especially by the posterior margin of tergum 10 being divided into a pair of upturned, falcate processes. The female has a distinctive, triangular but deeply divided subgenital plate (Li & Yang 2008 c).	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

The combination of a long, apically pointed mesal lobe and a pair of short, apically armed lateral lobes of the epiproct is apparently unique to this species.	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

039D7860FFD3FFFFFE8CFF3AFD10D9D1.taxon	etymology	Etymology. The species name honors the indigenous Viet people, and is used as a noun in apposition.	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

039D7860FFD3FFFFFE8CFF3AFD10D9D1.taxon	diagnosis	Diagnosis. The epiproct of this species appears generally similar to the deeply divided, trilobed structures of A. fleurdelia (Wu), A. nanlingensis Yang, Li & Sivec and A. elongata Li, Yang & Sivec (Li et al. 2005; Li & Yang 2007; Yang et al. 2005) but this species differs from all these in having the lateral processes of the epiproct subapically swollen.	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

039D7860FFD2FFFFFEA1FCDFFE34DEFC.taxon	discussion	Remarks The distinctive pronotal color pattern of these specimens has not been found among Vietnamese male specimens.

Pronotum pale brown over most of disk, paler along median suture. Wings pale brown, veins dark brown. Femora brown, tibiae dark proximally at knee and pale elsewhere. Female. Forewing length 7.5 mm. Subgenital plate lobes meet near midline; posterior margins form a broadly U-shaped notch; inner basal margins poorly sclerotized (Fig. 29). Sternum 9 entirely sclerotized; anteromedian margin slightly projecting. Median area of sternum 7 projects over base of subgenital plate.	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.

039D7860FFD2FFFFFEA3F9F3FB16D9A5.taxon	discussion	Remarks. No males with dark spots near the antennal bases were found among our samples. The pale area on the inner basal margin of the subgenital plate lobe appears to be distinctive, at least for the Vietnamese species we have seen.	en	Stark, Bill P., Sivec, Ignac (2010): Eight New Species Of Amphinemura (Plecoptera: Nemouridae) From Vietnam.
