Type
species:
Tarodes lineatus
Pocock, 1899
, by monotypy.
Diagnosis.
In general appearance,
Tarodes
resembles
Udvardya
, but it can be distinguished by the absence of mastidia on male chelicerae, embolus robust and short, epigyne with copulatory openings located posteriorly, copulatory ducts narrow, spermathecae two-chambered, with primary spermathecae enlarged and secondary ones markedly smaller, bean-shaped.
Description
. Cephalothorax of rectangular shape, longer than wide and relatively low, with posterior thoracic slope starting at two thirds of thoracic length (
Figs 1‒3
). Eye tubercles relatively small (
Fig. 2
). Clypeus very narrow (about 10% of AME diameter). Chelicerae inclined forwards, flat-fronted, with sclerotized lateral margins and transverse furrows on anterior surface; cheliceral dentition of fissident pattern, with two promarginal and one bicuspid retromarginal tooth (
Figs 3‒4
). Fangs relatively short. Endites divergent, without modifications. Labium subtriangular, longer than wide. Sternum narrow (
Fig. 5
), with anterior margin equal to labium width.
Male
abdomen cylindrical, not constricted (
Fig. 1
), with anterior hair tuft and dorsal and ventral scuta. Spinnerets of medium length, posterior ones slightly longer than anterior and median ones. First legs the longest and more robust than the others; femora I swollen and flattened laterally; tibiae I longer than femora, with ventral fringe of sparse setae and armed with two rows of ventral spines; metatarsi I with 3 pairs of ventral spines (
Fig. 1
). Leg formula: I- IV-II-III. Palpal organ: embolus (E) located apically at bulb, bent counterclockwise, retrolateral sperm duct loop (RSDL) S-shaped, retrolateral tibial apophysis (RTA) broad (
Figs 6‒7
). Epigyne as in diagnosis.
Remark.
The
type
species of
Tarodes
is known from New
Britain
. Prószyński (see in: "Monograph of (
Araneae
)
Salticidae
of the World
1995‒2015
”) shows illustrations of
Tarodes
specimens (of both sexes) collected from the
Solomon islands
archipelago (Guadalcanal and Vella Lavella) identified as
T. lineatus
. Those specimens probably belong to a new species, as their pedipalps vary in details from those observed in the
holotype
of
T. lineatus
. In this study they are depicted as
Tarodes
sp. (orange squares on the map,
Fig. 52
). The current diagnosis of the genus (see above) has been supplemented with the features of female genitalia, based on the drawings by Jerzy Prószyński.
Distribution.
Known from New
Britain
(
Papua New Guinea
) and
