Vibrissina

Rondani, 1861

Vibrissina is a of tachinid flies (Diptera: Tachinidae) comprising approximately 50 described distributed across the Holarctic and Neotropical regions. Species in this genus are of larvae (Hymenoptera: ), particularly members of Argidae, Tenthredinidae, and Diprionidae. The genus has been subject to recent taxonomic revision with five new species described from Rica in 2017. Vibrissina turrita, the type species, has been recorded as a parasitoid of rose sawfly (Arge ochropus) in Turkey.

Habitat

Tropical and temperate terrestrial environments associated with . In the Neotropics, occur in tropical rain forest and tropical dry forest up to 3 meters above ground level. In the Palearctic, species are associated with Rosa canina and other host plants of sawfly larvae.

Distribution

Holarctic and Neotropical regions. Documented from: Rica (Area de Conservación Guanacaste), Turkey (Bartın province), Mexico, and Scandinavian countries (Denmark, Norway, Sweden). Distribution likely broader but undersampled in many regions.

Host Associations

Arge ochropus - rose sawfly (Argidae), recorded in Turkey
Monoctenus sanchezi - Diprionidae, recorded in Mexico
Sericoceros krugii - seagrape (Argidae), recorded in Puerto Rico
Argidae (unspecified) - multiple reared from wild-caught larvae in Rica
Tenthredinidae (unspecified) - multiple reared from wild-caught larvae in Rica
Diprionidae (unspecified) - recorded

Life Cycle

development within larvae. flies eclose from pupae or mature larvae. Specific developmental stages and duration not documented in available sources.

Behavior

females parasitize larvae. specificity patterns suggest specialization on sawfly hosts (Hymenoptera: ) rather than lepidopteran caterpillars. Five Rican show minimal overlap with national museum collections, suggesting localized or -specific distributions.

Ecological Role

regulating . Part of the diverse tachinid fauna associated with caterpillar and sawfly in tropical and temperate forests. In Rica, the broader tachinid inventory suggests approximately 2,200+ may be present in Area de Conservación Guanacaste alone.

Human Relevance

Potential agent for pests. Vibrissina turrita has been identified as a of Arge ochropus, a significant pest of cultivated and wild roses in Turkey. The Rican inventory demonstrates utility of reared parasitoid collections for documenting tropical biodiversity.

Taxonomic activity

Recent descriptions of V. danmartini, V. hallwachsorum, V. randycurtisi, V. randyjonesi, and V. robertwellsi from Rica in 2017 represent significant expansion of known diversity. (CO1) has been employed for delimitation in this .

Sampling methodology

Most records derive from rearing programs collecting wild larvae and monitoring for rather than direct field observation of oviposition .
