description: <i>Baliomorpha cyclopsensis</i> spec. nov. (Figs 1-7) urn:lsid:zoobank.org:act: 6C3860CC-34F4-4960-A849-255D644D7A22 <b>Holotype:</b> &amp;male; MZB [Museum Zoologicum Bogoriense, Cibinong, Java, Indonesia], Indonesia, Papua, Sentani, Kab. Jayapura, S 02 o 32’04.0’’ E 140 o 30’47.5”, 14.iv.2018, light, leg. P.J.A. de Vries. <b>Diagnosis:</b> Easily distinguished from all the known species of <i>Baliomorpha</i> by its unique yellowish forewing pattern, especially by the rounded circle-shaped single eye-spot near the forewing tip. Such a beautiful yellowish forewing pattern is present at <i>Baliomorpha mariannae</i> Oláh, 2012, described from Batanta Island, Papua, Indonesia, but it has a bright yellow body, not a brown body and its forewing pattern is without the circle-shaped eyespot on the forewing subapical. <i>Baliomorpha caudicea</i> Neboiss, 1984 and <i>B. echinata</i> Neboiss, 1984, described from Papua New Guinea, also have bold yellow blotches on the forewing, but with different patterns. The structure of the male genitalia of <i>B. cyclopsensis</i> <b>spec. nov.</b> is very similar to those of <i>B. echinata</i> but with a different lateral profile of segment X as well as with different fine structures of the abbreviated, but free, and not retracted phallotremal sclerites and endothecal processes (fig. 4). <b>Description:</b> Male (in alcohol). Medium brown animal with seven yellowish light patches on forewing. Body and appendages brown, the dorsum of the mesothorax shining dark chestnut-brown. Antennae about twice as long as the forewing. Maxillary palp formula is I,II- IV-III-V. Forewing length 11 mm; Sc on the forewing with a less pigmented apical diverging fork connecting the subcosta with the costa and with radius1 apically; the nygma of the thyridial cell at about the middle of the cell; the forewing membrane is dark brown with seven yellowish patches: (1) the basal pair narrow longitudinal; (2) the middle pair with a most irregular costal patch; (3) the subapical pair with a larger costal patch; (4) a single subapical circle-shaped eye-spot. Male genitalia: Segment IX with a short ventrum and a longer humpy dorsum; the apical margin of the pleuron with a vertical row of strong setae. Segment X is short subtriangular in lateral view; diverging with narrowing apices in dorsal view; the cerci are located in the middle based on the lateral lobes and represented by setal slightly elevated rounded lobes. Vestigial paraproct emarginating segment X ventrolaterad and forming a sclerotized rodshaped phallic guide connecting the ventrobased part of segment X with phallotheca. The gonopods are undivided, no articulation discernible between coxopodite and harpago; straight, long rod-shaped in lateral view and arched in ventral view. Phallobase of the phallotheca right angled to the stem; phallic head with dorsal opening housing the phallotremal sclerites at the end of <i>ductus ejaculatoricus</i> as well as the elongated highly sclerotized endothecal processes. <b>Distribution:</b> Cyclops Mountains, the holotype is found at the lower southern slopes near Sentani, Papua, Indonesia. <b>Etymology:</b> Species epithet “cyclopsensis” refers to the type locality of the species, the Cyclops Mountains in Papua, Indonesia, as well as to its main distinguishing character of the single circle-shaped eye-spot on the forewing tips that symbolizes the single-eyed giants, the Cyclops of Greek mythology.
