[Entomology • 2021] Pliacanthopus (Malayamantis) visayanus, Compsogusa rheae & Theopompa schulzeorum • Three New Praying Mantises (Insecta: Mantodea) from Panay Island, Philippines

 Compsogusa rheae 
Schwarz, 2021

Three new species of praying mantids from the forest remnants of Panay Island, Philippines are described and illustrated. Pliacanthopus (Malayamantisvisayanus n. sp. extends the distribution of the genus, so far only known from Sundaland, to the Philippine archipelago. Compsogusa rheae n. gen. n. sp. and Theopompa schulzeorum n. sp. are bark mantids endemic to Panay. The ecological adaptations and the systematic and biogeographic affinities of the new taxa are discussed.

Compsogusa n. gen.
Type species: Compsogusa rheae n. sp., by monotypy.

Medium-sized, slightly depressed, relatively slender, brachypterous mantids with a disruptive color pattern related to the bark-living lifestyle.
The new genus is most closely related to the Oriental genus Compsomantis Saussure, 1872. The two genera share a largely similar body shape, the smooth pronotum with its distinct pattern of paramedian markings, and the shape and color pattern of the wings. Compsogusa is, however, more elongate than Compsomantis (ratio pronotum length/width >1.9 in Compsogusa, <1.9 in Compsomantis), has a more transverse frontal shield (about two times as wide as high in Compsomantis), and a less convex vertex with more protruding juxta-ocular bulges. In Compsomantis, the widest part of the pronotum is the prozona, while it is the supracoxal dilatation in Compsogusa. The number of postero-ventral spines on the fore-tibiae overlaps: 7–9 in Compsomantis, 9–10 in Compsogusa.

Etymology: Named for the striking resemblance to both its Oriental relative Compsomantis and the unrelated Neotropical bark-living genus Liturgusa, all of which share a similar lifestyle on the stems and branches of trees and bushes (Werner 1924, Schwarz 2003, Svenson 2014).

Compsogusa rheae n. sp.

Distribution: Panay Island, Philippines.

Etymology: named after Rhea Santillan (PhilinCon), multitasking secretary, bookkeeper, and facilitator of everything, without whose generous assistance I would not have accomplished anything in the Philippines.

Subtribus Humbertiellina Brunner de Wattenwyl, 1893

Theopompa schulzeorum n. sp.

Distribution: Panay Island, Philippines.

Etymology: named after Helga Schulze, Oldenburg, for her invaluable contributions to nature conservation in the Philippines and elsewhere, and after Tobias Schulze, Obermichelbach, for his numerous loans of Mantodea specimens to the scientific community over the years.
