Genus Capuyanus gen. nov.

urn:lsid:zoobank.org:act:0885CADA-AF23-4842-B24D-3F26826E5475

Type species

Capuyanus magwilangi gen. et sp. nov.

Etymology

The genus is named after Mr Benjamin G. Capuyan, the vice-mayor of Sagada, in acknowledgement of all his help, friendship and support during our fieldwork in Sagada.

Diagnosis

Closely related to Otraleus Günther, 1935 but easily distinguished by:

1. the strongly tapered subgenital plate in females, projecting over apex of tergum X.

2. the swollen and conical thornpads on the anal segment in males.

3. abdominal terga without well developed lobes posterolaterally.

Description

Male and female

Small and slender Necrosciinae (body length: female 47.4 mm, male 42.6 mm), apterous.

HEAD. Longer than wide, notched dorsally between antennae. Eyes circular and strongly projecting hemispherically. Antennae filiform, pedicellus shorter than scapus and round in cross section. Antennomeres narrower than pedicellus, varying in length towards apex.

THORAX. Pronotum granulose; behind anterior edge a transverse groove and a longitudinal groove not reaching the posterior margin. Posteromedially with a small granule or tubercle. Mesonotum elongated and granulose, with a tubercle posteromedially. Metanotum granulose, medially with a spinose tubercle subapically.

ABDOMEN. Median segment granulose and with a blunt tubercle or spine posteromedially. Terga II–VIII with a granule or blunt spine posteromedially. Females with subgenital plate slightly elongated and strongly tapered, projecting over apex of abdomen. Males with thornpads, strongly conically swollen and armed with spines. Vomer well developed, visible as a triangular black, flattened spine. Cerci small, round in cross section; apices rounded, projecting over apex of abdomen.

LEGS. Long compared to body, profemora compressed and curved basally. Femora and tibiae compressed laterally, with all carinae developed. Tarsomeres gradually decreasing in length. Claws small.
