Name
Cladobethylus Kieffer, 1922 – Wikispecies link – Pensoft Profile
- Cladobethylus Kieffer, 1922: 67. Type species: Cladobethyluscruciger Kieffer, 1922:69. Original designation.
Diagnosis
The most distinctive feature of the genus Cladobethylus is the impunctate welt that extends along the midline of the vertex from near the midocellus to the occipital carina. This feature is only shared with species of Magdalium Kimsey and Senesega Kimsey, although it is less well developed in these genera. Cladobethylus can be distinguished from those genera by the lack of an omaulus on the mesopleuron and the usually biangulate genal area, which is evenly curved in Magdalium and Senesega. In addition, Cladobethylus species have at most a weakly defined scrobal sulcus. The scrobal sulcus in Magdalium and Senesega is well defined.
Description
Vertex with low impunctate welt along midline from midocellus to occiput; eye with short sparse setulae; scapal basin usually with at least some cross-ridging; malar space with vertical sulcus extending from ventral eye margin to mandibular articulation; occipital carina present; posterior margin of head behind eye usually biangulate in side view; male flagellum elongate and cylindrical; female flagellum short, fusiform and usually flattened on one surface; pronotum with narrow posteromedial groove; mesopleuron without scrobal sulcus or omaulus; scutum with notauli and parapsides; both sexes fully winged, forewing Rs extended by evenly curved dark streak, costal cell widest medially, stigma large and broad, R1 not indicated, medial vein arising before cu-a; propodeum with long dorsal surface and abrupt posterior declivity, lateral propodeal angle undeveloped; hindcoxa with dorsobasal carina; tarsal claws edentate in females, with one small subbasal tooth and subbasal angle in males.
Distribution
(Fig. 1). Tropical Asia: Sri Lanka, New Guinea, Malaysia, Vietnam, Sarawak, Philippines, Indonesia (Sumatra), Borneo, South Korea and Japan.
Hosts
Cladobethylusinsularis was reared from eggs of the oil palm stick insect, Eurycanthainsularis Lucas (Phasmatodea: Phasmatidae), in Papua New Guinea (Kimsey et al. 2012[1]).
