Type
species
Phalangodus anacosmetus
Gervais, 1842
, by monotypy.
Diagnosis
Large (DSL 9.0–13.4) cranaine. Outline of dorsal scutum
type
alpha, with lateral borders smooth or with few granules (densely granulate in
P. palpiconus
). Ocularium high (
P. briareos
sp. nov.
,
P. cottus
sp. nov.
,
P. gyes
sp. nov.
and
P. palpiconus
) or low (
P. anacosmetus
and
P. kuryi
sp. nov.
). Scutal area I divided into two halves; II invading scutal area I; III with a pair of enlarged tubercles or moderately high spines (absent in
P. kuryi
sp. nov.
); IV entire (except in
P. palpiconus
) in left and right halves. Stigmatic area with a ventral pair of groups of granules (except in
P. kuryi
sp. nov.
). Pedipalp: Femur convex dorsally, with a dorsal row of enlarged tubercles; ventrally with a few tubercles restricted to medial region, bearing an enlarged basal apophysis; claw of the males conspicuously thickened (
P. anacosmetus
,
P. briareos
sp. nov.
and
P. palpiconus
). Metatarsus I of males not distally swollen. Femur IV of the males straight (
P. briareos
sp. nov.
,
P. gyes
sp. nov.
,
P. palpiconus
and
P. kuryi
sp. nov.
) to slightly curved (
P. anacosmetus
and
P. cottus
sp. nov.
), with a retrolateral distal/subdistal conical, enlarged tubercle (absent in
P. gyes
sp. nov.
and
P. kuryi
sp. nov.
). Penis: Ventral plate slightly longer than wide, with convex lateral borders, wide and shallow cleft on distal border. Setae on ventral plate organized in distal (9–12 pairs of MS C/D) and basal sets (4–5 pairs of MS A/B) or placed continuously (as a single set). Microsetae of the ventral plate present. Glans inflated medially. Stylus straight, surpassing distally the ventral plate (sligtlhy curved in
P. kuryi
sp. nov.
), distal tip widened and rounded, with erythrocytric-like stylar caps stylar caps.
