Leon, Stephanie & Weirauch, Christiane, 2016, Scratching the surface? Taxonomic revision of the subgenus Schizoptera (Odontorhagus) reveals vast undocumented biodiversity in the largest litter bug genus Schizoptera Fieber (Hemiptera: Dipsocoromorpha), Zootaxa 4184 (2), pp. 255-284 : 273

Schizoptera (Odontorhagus) monstrosa , n. sp.

( Figs 3 , 6 and 7)

Diagnosis. Distinguished among species of Schizoptera (Odontorhagus) by the rounded head, the distinctly asymmetrical subgenital plate, with a small slit-like lateral incision and a triangular caudal incision, the broad and lobe-shaped process of the subgenital plate, the bifurcating process of the right paramere, trifurcating right conjunctival appendage, the short, serrated and forking vesica, and the dorsal hump of the anophore.

Holotype: PANAMA: Cocle: Antón District Co.: Panama: Cocle Rio Indio Lodge , N El Valle, 8.6008 ° N 80.1303 ° W, 24 Feb 2012 – 27 Feb 2012, 1Ƌ (00091615) (FSCA) (microscopic slide mount).

Description. Male: length: 1.46 mm; body broadly ovate; COLORATION: general coloration light brown; fuscous patch absent; Sc+C distinctly lighter than remainder of hemelytron ( Fig. 3 ). SURFACE AND VESTITURE: as in subgeneric description. STRUCTURE: HEAD: slightly rounded in ventral view ( Fig. 3 ); eyes about 1/2 as wide as synthlipsis. THORAX: as in subgeneric description; hemelytron as in subgeneric description; M2 vein distinctly curving anteriorly toward wing margin, anterior membranal cell wedge-shaped. ABDOMEN: as in subgeneric description; stVI without process on posterior margin; subgenital plate distinctly asymmetrical, with a small lateral and large caudal incisions ( Fig. 6N ) forming the process of subgenital plate; process of subgenital plate broad and round; tVII rectangular; tVIII weakly trapezoidal and sclerotized; length of tVIII about 1/2 length of tVII. GENITALIA: py as in subgeneric description; rp as in subgeneric description with a long, tapering stem; lp as in subgeneric description, with two lobate dorsal processes; rca narrow and thin with a serrated base; lca small, about 1/4 length of rca and spatulate with a toothed tip ( Fig. 6N ); vesica short and serrated with a forked apex, anophore as in subgeneric description, with a dorsal hump ( Fig. 6N ).

Female: Unknown.

Distribution. Known only from the type locality.

Etymology. Named after the monstrous morphology of the subgenital plate and the uniquely forked vesica and bifurcating process of the right paramere. From the Latin “monstrosus” meaning monstrous.
