Cryptoxilos
Viereck, 1911
Cryptoxilos is a of in the Braconidae, Euphorinae, established by Henry Lorenz Viereck in 1911 with C. dichromorphus as the type . The genus contains eight described species distributed across multiple continents. Members are known to parasitize bark beetles (Scolytinae, Coleoptera), with documented associations including Chaetoptelius mundulus in New Zealand and Hypothenemus species in Fiji.

Identification
The was historically divided into subgenera, but this system has been abandoned due to inconsistent application; subgenus Cryptoxiloides is now treated as a junior synonym. -level identification requires examination of morphological characters, with some species not easily assignable to the former subgeneric categories.
Distribution
Documented from New Zealand, Fiji, Europe (Poland), East Asia (China, Korea, Japan region), and North America. The has been described as likely .
Host Associations
- Scolytinae (Coleoptera) - bark beetles. Specific documented include Chaetoptelius mundulus on dead Pittosporum trees in New Zealand, and Hypothenemus curtipennis and H. dorsosignatus in Commersonia bartramia in Fiji.
Behavior
females parasitize adult bark beetles. The C. thorpei has been observed associated with scolytine beetles on dead Pittosporum trees, and C. beaveri with cryphaline ambrosia beetles.
Ecological Role
agent of bark beetles (Scolytinae), potentially regulating of these forest pests.
Human Relevance
Potential interest for of bark beetle pests in forestry and agriculture. Documented associations with economically significant groups including ambrosia beetles.

Taxonomic revision
The subgenus classification system for Cryptoxilos has been abandoned; Cryptoxiloides is now treated as a junior synonym. This revision was prompted by the inability to assign newly described (C. thorpei, C. beaveri) to existing subgenera based on consistent character states.
Type species
Cryptoxilos dichromorphus Viereck, 1911 was designated as the type by the original describer.
