Name
Mononeuron Fischer – Wikispecies link – Pensoft Profile
- Mononeuron Fischer, 1981: 47–51 (original description); Marsh 1997[1]: 214 (Key); Yu et al. 2005[2] (catalogue).
Type species
Mononeuron duguetiae Fischer
Diagnosis
Mononeuron may be distinguished from the remaining doryctine genera by having the following combination of features: frons excavated; occipital carina meeting hypostomal carina; propodeum with semicircular or subtriangular shaped basal median areas (Fig. 2C); fore wing vein r-m present (Fig. 3C); first subdiscal cell of fore wing open at apex (Fig. 3C); hind wing vein SC+R absent (Fig. 3D); hind wing vein cu-a absent or spectral (Fig. 3D); hind wing vein 1A incomplete (Fig. 3D); hind wing vein M+CU equal to or slightly greater than vein 1M (Fig. 3D); hind wing vein m-cu slightly curved toward wing apex or straight to wing margin but never angled toward wing base (Fig. 3D); hind coxa with a distinct baso-ventral tubercle; basal sternal plate of first metasomal tergum less than 0,25 length of tergum; metasoma sculptured on first three terga (Fig. 2C); ovipositor apex strongly sclerotized and with a single nodus (Fig. 2D). Mononueuron is morphologically similar to Allorhogas, but it can be distinguished from members of this genus by having the vertex at least partially striate (Fig. 2B) (coriaceous in all described species of Allorhogas); hind wing vein SC+R absent (present in all described species of Allorhogas except Allorhogas ingavera Marsh); hind wing vein cu-a absent or spectral (sclerotized or nebulose in most described species of Allorhogas, only spectral in Allorhogas argentinus Brèthes and Allorhogas shawi Marsh); hind wing vein 1A incomplete (always reaching vein cu-a in other described species of Allorhogas); ovipositor long, about 1.5 times length of metasoma (Fig. 3B) (generally shorter than metasoma in most of the described species of Allorhogas, longer than metasoma in Allorhogas gallicola Gahan).
