Paulianidia valohoaka Janák & Baňař , sp. nov.

( Figs. 31–37 , 121 )

Type locality. Madagascar, Ranomafana , Valohoaka

Type material. Holotype ♂: MADAGASCAR: “RNF/ Sept. 2012 /10 MADAGASCAR, RANOMAFANA N. P.; 6.x.2012 S21°17’51.8” E47°26’35.1”; 1008m VALOHOAKA, sifting litter, Winkler app. extr. L.S. Rahanitriniaina lgt.” // “HOLOTYPUS Paulianidia valohoaka sp. nov., Janák & Baňař det. 2023” ( MMBC).

Description: Body length 5.1 mm, forebody length 3.0 mm. Reddish brown, abdomen, mouthparts and antennomeres reddish, legs yellow ( Fig. 31 ).

Head ( Fig. 32 ) moderately convex, slightly longer than wide (L/W = 1.06). Surface with moderately coarse and very dense umbilicate punctures, interstices smaller than diameter of punctures. Eyes small, temples on average about 1.4 times as long as eyes (R = 1.39), slightly roundly narrowed posteriorly. Antennae long and slender, fifth antennomere about 1.4 times as long as wide (L/W = 1.37), tenth antennomere transverse (L/W = 0.73).

Pronotum ( Fig. 32 ) egg-shaped, moderately convex, with shallow basal impressions, about 1.2 times as long as wide (L/W = 1.17) and slightly narrower than head (PW/HW = 0.94). Sides slightly roundly widened posteriorly. Surface with moderately coarse and sparse punctures, interstices shining, without microsculpture, about as large or larger than diameter of punctures, punctation more coarse and less dense than that on head and less dense along moderately narrow unpunctured middline; middline enlarged in anterior and basal part of pronotum.

Elytra ( Fig. 32 ) subrectangular, with very slightly rounded sides and shallow depression along suture in first quarter behind scutellum, about 1.1 times longer than wide (R = 1.12). Surface moderately coarsely and densely punctured. Interstices mostly as large as diameter of punctures, shining, without microscupture.

Abdomen ( Fig. 31 ) slightly widened to segment V, very finely and densely punctured. Interstices shining, without microsculpture. Tergite VII with distinct membranous fringe apically.

Female unknown.

Differential diagnosis. The new species is similar to P. vicina Jarrige, 1978 , known only by a female holotype, but differs by the missing microsculpture between punctures on tergites, unpunctured midline on pronotum visible both in anterior and basal parts and shorter and wider elytra (R = 1.12, cf. Fig. 32 in P. valohoaka and R> 1.12, Fig. 115 in P. vicina ).

Etymology. The name is related to the type locality.

Distribution. Paulianidia valohoaka Janák & Baňař , sp. nov. is currently recorded only from Valohoaka, a part of the Ranomafana National Park in the southern eastern part of Madagascar ( Fig. 121 ).

Bionomics. The type specimen was sifted from forest litter.
