Oh my goodness! Unless you are a Tree of Life developer, you really shouldn't be here. This page is part of our beta test site, where we develop new features for the ToL, often messing up a thing or two in the process. Please visit the official version of this page, which is available here.

Introduction

The subfamily was erected to accomodate a single genus with the single species described recently from Japan. The biology is unknown. Several specimens were collected in flight interception traps. Larvae unknown.

Characteristics

Body dark brown, length from 4.3 to 4.6 mm, depressed, covered with short, erect hairs. Prosternum well developed, what differs Nipponocyphon from other scirtids. Elytra with rows of punctures. Mandibles shortly triangular, apex unidentate, with well developed mola. Maxillary lacinia with distinct apical hook (uncus). Apical palpomere of maxillary palpi widened, securiform.

Discussion of Phylogenetic Relationships

Nipponocyphon forms the most basal clade of Scirtidae. It shows several similarities with Declinia, and relationships between both taxa need further studies. It seems that finding larvae of these problematic taxa may be of great importance for resolving their phylogenetic relationships and taxonomic status.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
