Cagayanacoris menardi sp. nov.

( Figs.1–5 )

Etymology. This interesting new taxon is dedicated to Katrina Menard, Sam Noble Oklahoma Museum of Natural History who collected this specimen from a berlaise sample and made available for study this material and recognizing her very appreciated activities as co-editor of Zootaxa.

Type material: Holotype (micropterous male) labelled: Philippines: Prov. Cagayan / Valley. Gattaran Munc. Nancin / Forest Station . Malaise trap leg./ 17.96967N 121.65390E 166m / 27.V.2017 Berlaise / Siler Brachymeles Expedition 4 // Catalog No. / 66733 //( OMNH) . Paratypes: 3♂, 1♀ collected with holotype, Catalog No. 66729, 26731, 66734 and 66732 ( OMNH, 2♂♂ CEHI) which are designated and labelled accordingly. One L 5 (Catalog No. 66730 in OMNH) belongs to the same taxon .

Description. Head: Distinctly wider than long (1.15/0.85); clypeus as long as antenniferous lobes; genae thin as long as clypeus contiguous at apex; antennae about 1.7times as width of head (1.95/1.15), segment I thickest and bent, II shortest and III longest are thinner, IV fusiform; length of antennal segments I/II/III/IV = 0.5/0.35/0.7/0.4; eyes stalked; postocular lobes roundly converging to constricted neck; vertex raised and beset with stiff, apically curved yellowish hairs; rostrum arising from a slit-like atrium in a transverse basal ridge with shiny knob-like tubercles at both ends, rostral groove wide and open posteriorly without carinate borders; rostrum with a single long stiff erect bristle at half of its length.

Pronotum: Strongly transverse, consisting of a deeply punctured anterior disk with triangulate flat anterolateral expansions and two median tubercles and a smooth transverse ridge delimited posteriorly by a deep furrow separating pronotum from mesonotum.

Mesonotum with triangular scutellum, raised and longitudinally carinate at middle; rudimentary lateral wing pads reaching ½ of scutellum; metanotum consisting of oval sclerites lateral of scutellum, posteriorly fused to mtg I+II, the latter marked by sinuate carinae.

Abdomen: Tergal plate separated from fused mtg I+II by a conical suture, slightly raised along midline; deltg II+III fused, lateral margins of deltg III–V straight, VI+VII slightly concave. Male pygophore about 1.5 times wider than long, rounded posteriorly, ptg VIII triangular shorter than pygophore bearing spiracle VIII.

Venter: Metathoracic scent gland opening widening toward lateral margin; median part of meso- and metasternum fused to sternum II, sterna III–VII separated by deep transverse furrows; sternite VII of male smooth and glabrous at middle with a deep median pit, rugose elsewhere ( Fig.5 ).

Female: Basically as male, but of larger size and more rounded abdomen; tergite VIII consisting of triangular ptg VIII bearing spiracle VIII connected by a narrow bridge.

Measurements: Holotype: Length 4.6mm; width of abdomen across tergite III = 2.25; scutellum length / width 0.7/1.35; Paratype female: Length 5.6mm; head l/ w 0.9 /1.25; l/w pronotum 0.75/2.0; l/w scutellum 0.85/1.7; length of antennal segments I/II/III/IV = 0.55/0.35/0.75/0.4; width of abdomen across tergite III = 3.0.

Discussion. Apterous and micropterous Aradidae predominantly occur and are recorded from stable environments present in undisturbed tropical or subtropical rainforests. They have a very limited range of movement and distribution; hence they are mostly regarded as endemic to the region or locality where they were collected.
