Name
Neoperla brevistyla Li & Murányi sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material
1 male (CAU), China: Fujian Province, Mt. Wuyishan, Sangang, 735 m, 27°74.78'N, 117°68.31'E, light trap, 12 Jul. 2009, Li Shi and Xiaoyan Liu. Paratypes: 2 males, the same data as holotype, (CAU); 6 males, the same locality, 16 Aug. 2006, Hui Dong, (HIST).
Male
Forewing length 15.6–16.0 mm. Distance between ocelli about as wide as diameter of the ocellus. Head slightly wider than pronotum, with an obscure quadrate dark stigma on frons and a brown area covering ocelli (Fig. 1a); compound eyes black and antennae dark; maxillary palpi brown. Pronotum with obscure rugosities and dark brown anterior and lateral margins, thorax mostly brown (Fig. 1a); wing membrane subhyaline, veins brown; legs brown but distal half of femora and basal one fourth and distal one sixth of tibia dark brown, tarsi dark brown (Fig. 2d). Terminalia. The posterior margin of tergum 7 with quadrate, rounded and elevated process covered with dense sensilla basiconica (Fig. 2a). Tergum 8 with recurved tongue-like process (Figs 2a). Tergum 9 without sensilla basiconica. Hemitergal processes of tergum 10 with enlarged base and beak-like apex (Figs 1b and 2b). Aedeagal tube strongly sclerotized, with a pair of separate ventroapical lobes, in lateral view nipple like and triangular in shape (Figs 1c and 2c). Aedeagal sac short and gradually tapering to apex, forming nearly a right angle with tube; basal part unarmed and plump, median part with a patch of small spines and apex bearing fine spinules (Figs 1c and 2c).
Female
Unknown.
Etymology
The specific epithet refers to the short ventral lobe of aedeagal tube.
Distribution
China (Fujian).
Diagnosis and remarks
Neoperla brevistyla belongs to an informal group of species including Neoperla biprojecta Du, 2001, Neoperla duratubulata Du, 1999, Neoperla qingyuanensis Yang & Yang, 1995, Neoperla yentu Cao & Bae, 2007 that bear similar terminalia, sclerotized aedeagal tube and short sac, and a pair of separate ventral lobes of aedeagal tube (for comparison, see figs 3–4, 7 in Li et al. 2013[1], figs 25–13 in Du 1999[2], figs 75–77 in Stark and Sivec 2008[3], and Fig. 6). This species shares a pair of short ventral aedeagal lobes with Neoperla biprojecta Du, 2001 (fig. 4 in Li et al. 2013[1]), but the lobes of Neoperla brevistyla are triangular andstouter, a patch of dorsal armatures occurs at midlength of the sac (Fig. 1c) which is absent in Neoperla biprojecta.
