description: <i>CITROGRAMMA PINYTON</i> MENGUAL SP. NOV. <i>Description</i> See description of <i>C. pintada</i> above. Morphologically, <i>C. pinyton</i> and <i>C. pintada</i> are identical, with the same variation in males and females. The only differences between them are the male genitalia (see Figs 155, 156) and that specimens of <i>C. pinyton</i> have more black hairs on anepisternum than those of <i>C. pintada</i>. <i>Length (N = 5):</i> Body, 9.2–10.1 (9.7) mm; wing, 8.9–9.3 (9.0) mm. <i>Geographical distribution:</i> New Guinea. <i>Etymology:</i> The specific epithet is derived from the Greek <i>pinytos</i> meaning discreet, cautious (Brown, 1956: 457). Species epithet to be treated as neuter adjective. <i>Differential diagnosis:</i> As mentioned above, <i>C. pinyton</i> and C. <i>pintada</i> belong to the same species group, but they can only be separated by male genitalia. The females of <i>C. pinyton</i> were separated based on the locality and dates because of the lack of morphological differences with females of <i>C. pintada</i>. The three males of <i>C. pinyton</i> were collected in Bome (Goilala District, Central Province, PNG) during March and April with other three females. The males of <i>C. pintada</i> were collected in Wau and surroundings (Bulolo District, Morobe Province, PNG) from June to December, mainly in October. The localities of Wau and Bome are located at each side of Owen Stanley Range, which divides the south-eastern part of PNG in two slopes facing Coral Sea south and Solomon Sea north. This central mountain-chain has several high mounts, such as Mount Victoria (4072 m), Mount Chapman (3376 m), and Mount Albert Edward (3990 m). In some way, Owen Stanley Range might have separated these two species in the past so that they share adult morphology but not male genitalia. Holotype male deposited in the Bernice P. Bishop Museum (Honolulu, Hawaii, USA) and labelled: ‘NEW GUINEA: PAPUA/Owen Stanley Range/ Goilala: Bome, 1950 m / III–16–31–1958 ’ ‘W.W.
