Paraethus lisi n. sp.

Type material: Holotype, Ƌ [ Australie], Collection NOUALHIER ( MNHN) ; Paratype, 1 Ƌ, same data as holotype ( MNHN) (both dissected, genitalia in microvials on the same pin as the specimens) .

Description

Body elongate, shiny, coloration black and brown. Head ( fig. 1): Genae punctate, clypeus and middle part of frons less punctate; in addition to the two primary setae, three setae and eight peg-like setae on the margin of juga; clypeus inclosed in the paraclypei, subapically without setigerous punctures; eyes yellowish to brownish, each with an apical spine; ocelli large, light yellowish-brown; antennae ligth brown, 2 nd and 3 rd segments subequal, smaller than 4 th by about 20 %, last longer (0.39, 0.38, 0.47 and 0.55 mm, respectively); rostrum pale brown, long, reaching hind coxae, second segment strongly curved ventrad.

Thorax: Pronotum about 1.8 times broader than long, black, umbones not swollen; pronotal disc densely, almost evenly punctured (except callal areas); each lateral margin with about 12 submarginal setigerous punctures bearing hair-like setae. Scutellum black, its disc densely and evenly punctured, punctures of same size as those on pronotum. Hemelytra yellowish-brown, clavus with one complete and two partial rows of punctures; mesocorium with two rows of punctures, parallel to clavo-corial suture, mesocorial disc with dense punctation, punctures smaller than those on scutellum; exocorium weakly punctured; costa with 1 (♀) or 5 ( Ƌ) setigerous punctures; membrane semihyaline, light yellowish, distinctly surpassing tip of abdomen. Propleuron with a few punctures in depression; evaporative areas ( fig. 2) large, on metapleuron with wedge-shaped polished band running to apex of vestibulum, which is fitted with a claw-like tooth posteriorly ( fig. 3). Legs light brown; fore tibia ( fig. 13) apically broadened and compressed, its apex slightly prolonged forming a short process similar to that found in the subgenus Eolactistes LINNAVUORI of the genus Lactistes SCHIØDTE , dorsal margin of fore tibia with 11 short stout spines, tarsus yellowish-brown, not inserted at the apex; middle tibia slightly flattened; posterior tibia conspicuously compressed and somewhat broadened, margins with many long spines.

Abdomen: Sternites brown or dark brown, lateral fourths with many distinct punctures, especially along hind margin.

Male genitalia: Paramere ( fig. 17), penis nearly straight ( fig. 18), upper conjuctival process spatulate ( fig. 19).

Female genitalia: Spermatheca ( fig. 26), receptacle and translucent dilation of the duct of about the same size; intermediate part slightly swollen; triangular fold of the vaginal wall of about the same width as the posterior part of the duct, very lightly sclerotized on the outside.

Measurements: Total length Ƌ 6.4 mm – ♀ 7.0 mm, width Ƌ 3.4 mm – ♀ 3.6 mm, ocular index 3.1, interocellar index 3.0-4.1.

Derivation nominis: It is a pleasure for me to dedicate this species to my colleague JERZY LIS, in recognition of his great contribution to the knowledge of Cydnidae .

Distribution: Australia (without precise locality). Discussion

Due to its peculiar fore tibiae, P. lisi can be compared only to P. jani LIS, 1995 . The two species are very similar, but can be easily distinguished by a set of characters (table 1).
