Planicapitus luteus Taszakowski, Kim & Herczek, 2020

Planicapitus luteus Taszakowski, Kim & Herczek, 2020: 76 , Figs. 1–5 (new species); Taszakowski et al. 2023: 185 (checklist).

Diagnosis. Distinguished from P. brunneus by the following combination of characters: bottom half of the head large Y-shaped brown macula; gena whitish yellow; pedicel subequal to than combined lengths of flagellomeres; corium brown with a pale spot medially; embolium and posterior part of cuneus yellowish, right paramere 0.56x as long as left one; apical process forms an angle of 110° with the basal process.

Description. See the original description in Taszakowski et al. (2020). Male genitalia: genital capsule impunctate, covered with long setae; aedeagus delicate; endosoma sacciform and membranous, weakly sclerotized inside, outer subapical and apical part more sclerotic, clothed with dense spinules ( Fig. 5B ); left paramere scythe-shaped, apical process long, vertically curved, slightly widened in distal part, sensory lobe slightly developed, with few setae ( Fig. 5C ); right paramere 0.56x as long as left one, with knee-shaped sensory lobe, apical process long, slightly curved at apex; apical process forms an angle of 110° with the basal process ( Fig. 5D ).

Material examined. Holotype ( ♂): ‘ Borneo, Sabah / Danum Valley / 70km W Lahad Datu / M.J. & J.P. Duffels // East Ridge Trail / 150m / 2.XII.1989 // sample Sab. 53 / understory rainforest, / at light’ ( ZMAN); ♂: ‘ BRUNEI: Ulu / Temburong ridge / ii.–iii. 1982 // M.C. Day / B.M. 1983–75.’ ( NHM).

Distribution. Brunei, Malaysia ( North Borneo) ( Fig. 3N, P ).

Biology. Unknown.
