Name
Antrocephalus validicornis (Holmgren, 1868) – Wikispecies link – Pensoft Profile
- Haltichella validicornis Holmgren, 1868: 438 (♂, Java (NHRM); lectotype designated by Narendran 1989[1]).
- Antrocephalus validicornis; Narendran 1989[1]: 45.
Material
1 ♀ (RMNH), “Vietnam: Ninh Thuân, Núi Chúa N. P., northeast part, Mal[aise] traps, 90–150 m, 23–30.v.2007, C. v. Achterberg & R. de Vries, RMNH’07”.
Diagnosis
Antrocephalus validicornis comes near Antrocephalus phaeospilus Waterston in the key to species provided by Narendran (1989)[1], but differs from it in having: 1) hind femur more than twice as long as wide (in Antrocephalus phaeospilus less than twice as long as wide); 2) hind femur black with base and apex red (in Antrocephalus phaeospilus completely red); 3) apex of scutellum only emarginate; not bi-lobed (in Antrocephalus phaeospilus apex of scutellum bi-lobed) and 4) eyes bare (in Antrocephalus phaeospilus eyes setose). Antrocephalus validicornis superficially resembles Antrocephalus atulyus Narendran (Narendran, 1989), but differs from it in having: 1) comb of teeth on ventral margin of hind femur starting near middle length of femur to apex (in Antrocephalus atulyus comb of teeth starts well before middle length of femur); 2) interstices of pronotum and of anterior part of mesoscutum rugose and somewhat carinate (in Antrocephalus atulyus interstices mostly smooth and shiny); 3) apex of scutellum emarginate (in Antrocephalus atulyus apex of scutellum bi-lobed) and 4) fore wing without any brown or black infuscation (in Antrocephalus atulyus fore wing with brownish infuscation adjoining MV). Among Vietnamese species of Antrocephalus, Antrocephalus validicornis comes near Antrocephalus nasutus (Holmgren) in having PMV distinctly longer than MV, but differs from it in having: 1) hind femur with ventral comb of teeth starting from middle length of hind femur, occupying 0.5 × length of femur (in Antrocephalus nasutus comb of teeth starts well before middle length of hind femur, occupying 0.7 × length of femur); 2) apex of scutellum shallowly emarginate (in Antrocephalus nasutus apex of scutellum deeply incised) and 3) hind femur black with base and apex red (in Antrocephalus nasutus hind femur red).
Description
♀♂. Head with post-orbital carinae indistinct or absent; geno-temporal furrow distinct; eyes bare; interstices of pronotum and anterior part of mesoscutum rugose and somewhat carinate; apex of scutellum carinate; fore wing without black or brown infuscation; PMV distinctly longer than MV; hind femur black with base and apex red, its length more than twice its maximum width; hind femur without an inner basal tooth; metasoma with two carinae on T1, carinae much shorter than 1.25 × T1.
Host
Unknown.
Distribution
Vietnam (new record), Indonesia (Java), Malaysia (Narendran 1989[1]).
