DERIVATION
OF
SPECIES
NAME
.— The species epithet,
ocellata
, is the Latin adjective meaning having little eyes or marked with spots. The name refers to the small, faint dark spot on interval 3 within the subapical pale area of each elytron at the insertion point of the subapical discal setiferous pore.
RECOGNITION
.— Size small for genus, SBL of male and female =
9.2 mm
. Members of this species (
Fig. 23A
) key to
Eurydera mormolycoides
Coquerel (1851)
in Jeannel’s (1949) key on the basis of the following combination of features: size small; head (
Fig. 24A
) with frontal furrows deeply impressed, smooth, divergent posteriorly and without a transverse impression uniting them, posterior part of frons smooth, narrow and triangular, without lateral grooves prolonged posteriorly beyond the posterior border of the eyes; mandibles short and broad, lateral border not broadly explanate, lateral margin only slightly convex; pronotum cordate, distinctly narrowed basally, lateral margins angulate at insertions of midlateral setae; elytra short, round and black, each with a reddish subapical spot tangential to the medial suture as well as subhumeral and subapicolateral reddish areas and reddish apical spines, elytral intervals moderately convex; median lobe of male genitalia without a large, angulate projection on the ventral margin of the shaft near the base. They differ from
E. mormolycoides
members in having: dorsal surface slightly shiny (dull in
E. mormolycoides
members); pronotum with lateral explanations pale testaceous (darker in
E. mormolycoides
members), anterior angles broadly rounded (more narrowly rounded in
E. mormolycoides
members) and lateral margins with shallow but distinct sinuation anterior to hind angles (sinuation absent from or less distinct in
E. mormolycoides
members); elytra with larger but less distinct (less contrasting with rest of elytra) pale subapical macula with black eye spot on interval three (macula extended further laterally and lateroanteriorly than in
E. mormolycoides
members) and apical spine about half as long as spine in
E. mormolycoides
members. Finally, the median lobe of the male genitalia (
Figs. 24B–C
) has a thicker shaft throughout and an apex shorter and thicker in lateral view (
Fig. 24B
) and broader and straighter in dorsal view (
Fig. 24C
) than in
E. mormolycoides
males (see Jeannel 1949, Fig. 492b).

GEOGRAPHICAL
DISTRIBUTION
.— At present, known only from the
type
locality.
HABITAT
DISTRIBUTION
.— The
holotype
specimen was collected in a malaise trap in secondary montane rainforest in the Talatakely area at an elevation of
1030 m
. The
paratype
specimen was collected at ultraviolet light in secondary montane rainforest near the junction of the Namorona River and a small tributary stream.
