Cryptanura

Brullé, 1846

Species Guides

Cryptanura is a of ichneumonid wasps in the Cryptinae, containing at least 38 in North America. These are of other insects, with documented including longhorn beetles (Cerambycidae). The genus includes species that serve as models for by phytophagous . At least 30 species occur in Mexico, with the genus distributed from North America through Central America to South America.

Identification

Distinguished from similar Cryptinae by combination of: dark body with white spots on and ; entirely red ; long with black and white banding; legs with yellow and red colouration. For North American , consult the key in Zoosystematica Rossica (2006). Distinguished from its mimic Holymenia clavigera by wing structure (membranous wings with venation vs. ), antennae spanning movements during foraging, and presence of ovipositor .

Images

Appearance

Medium-sized ichneumonid wasps with long (approximately 87% of body length in observed specimens). Dark body with white spots on and ; entirely red. Antennae with black and white colouration. Legs with yellow and red colouration. Prominent ovipositor (3.2 mm in measured specimen). Hyaline wings with salient nervures.

Habitat

Seasonal secondary forest (semideciduous seasonal forest); native forest fragments. Forages near leaf litter on forest floor. Associated with fallen trunks of woody plants including Lacmella panamensis.

Distribution

North America (38+ ), Mexico (30 species), Panama, and Brazil (Minas Gerais State).

Seasonality

Peak foraging activity observed from 09:00 to 12:00 in Brazilian .

Host Associations

Taeniotes scalatus - New record; Cerambycidae: Lamiinae larvae in fallen trunk of Lacmella panamensis

Behavior

Solitary forager on forest floor, searching in and above leaf litter. Remains resting on substrate (fresh or dry leaves and branches) for approximately 7.00 ± 2.30 seconds on average. Performs spanning movements of during foraging. More abundant than its mimic Holymenia clavigera in observed (18 vs. 4 specimens).

Ecological Role

of wood-boring larvae; contributes to biocontrol of timber and agricultural pests. Serves as model for by phytophagous , providing protective signaling to mimics.

Human Relevance

Potential biocontrol agent for suppression of cerambycid pests damaging timber crops and agriculture. Subject of mimicry research due to role as model for coreid mimicry.

Taxonomic diversity

The is taxonomically diverse with 10 new described from Mexico in 2006. Two synonymies established: Cryptanura ectypa (Cresson, 1873) = C. vallis Porter, 1977; and C. nitidiuscula Cameron, 1886 = C. bicarinata Cushman, 1945.

Mimicry system

Strong morphological and behavioural convergence with Holymenia clavigera represents one of few documented cases of involving phytophagous and ichneumonid wasps. Similarities include colour pattern, size, foraging behaviour, and sympatric distribution.
