Coeliniaspis Fischer, 2010 (Braconidae, Alysiinae, Dacnusini) is recorded from China and Russia for the first time. Coeliniaspis insularis (Tobias, 1998) is reported from China (Fujian), redescribed and illustrated. A key to the species of the genus Coeliniaspis Fischer is added. Coeliniaspis insularis (Tobias, 1998) and C. rufiventris (Tobias, 1998) are new combinations.


Taxonomy, parasitoids, new combination, Oriental, China, Fujian, Russia, Dacnusini , Coeliniaspis insularis


The genus Coeliniaspis Fischer, 2010 (Hymenoptera, Braconidae, Alysiinae, Dacnusini) is a monotypic genus described from Cambodia, with C. kohkongensis Fischer, 2010, as type species. According to Griffith’s (1964) diagnosis, this genus belongs to the Coelinius genus-group. Its biology is unknown, but related genera contain (ovo-)larval parasitoids of Chloropidae (Diptera).

Coeliniaspis is reported here for the first time from China and Far Eastern Russia; it is also the first record outside Cambodia. The species found in China, C. insularis comb. n., is redescribed and illustrated. Keys to the genera of Coelinius genus-group and the species of Coeliniaspis Fischer are provided.

Material and methods

The Chinese specimens were collected in Fujian (southeast China) by sweep-netting in August 2001. For the terminology of morphological features and sculpture, measurements and wing venation nomenclature, see van Achterberg (1988, 1993). The morphological characters were examined and photographed using a Leica M205C digital stereomicroscope. The specimens are deposited in the Beneficial Insects Institute, Fujian Agriculture and Forestry University (Fuzhou, China).


Coeliniaspis Fischer, 2010

Coeliniaspis Fischer, 2010: 646. Type species (by original designation): Coeliniaspis kohkongensis Fischer, 2010 (examined).


Flagellomeres of antenna densely setose; clypeus flattened, with ventral lamella or more or less depressed medially and sublaterally protruding (Fig. 7; see arrow); mandible with four teeth, additional (= fourth) tooth dorso-basally on middle tooth (Fig. 10); vein r of fore wing arising from or before middle of pterostigma (Fig. 1); second metasomal tergite coarsely sclerotized, distinctly sculptured and with complete sharp lateral crease.


Coeliniaspis is included in the Coelinius genus-group because of the presence of the longitudinal sculpture on the second metasomal tergite, similar to that of the first tergite, the mandible with an additional tooth between first and second teeth, the metapleuron with rugose sculpture and sparsely pubescent, and the first subdiscal cell of fore wing elongate (Fig. 1). For the differences within the Coelinius genus-group, see the key below.

The redescription by Fischer (2001) clearly stated that the clypeus is ventrally indented (“eingedellt”) and is similar to the type species of the genus Coeliniaspis Fischer, 2010. Therefore, we transfer this species (only known from Far Eastern Russia) to the latter genus; the genus is new for Russia.
