Nineteen new genera and 82 new species of Cremnorrhinina from Australia, including analyses of host relationships and distributions (Insecta: Hemiptera: Miridae: Phylininae: Cremnorrhinini) Author Randall T.

Schwartz text Bulletin of the American Museum of Natural History 2016 401 1 279 journal article 39161 10.5281/zenodo.269465 4e88a985-9cb4-4912-9b10-71db96ba36f5 http://hdl.handle.net/2246/6649 269465 Myrtophylus calytrix , new species Figures 60, 61, map 17, table 1, plates 20, 21, 50 DIAGNOSIS: Recognized by relatively large body size and endosoma with two subequallength apical spines, a straight subapical, ventrally directed lateral spine, and faint plate near secondary gonopore (fig. 61, pl. 21). Distinguished from its congeners by the larger size and apical endosomal spines of subequal length. DESCRIPTION: MALE : Elongate, slender; mean total length 4.26, mean pronotum width 1.00. COLORATION (pl. 20): Bright yellow, including all appendages (in preserved specimens); membrane weakly fumose, veins pale with a diffuse dark spot at apex of cells. SUR- FACE AND VESTITURE (fig. 60A, B, pl. 20): As in generic description. STRUCTURE (pl. 20): Elongate, nearly parallel sided. Head (fig. 60A, pl. 20): As in generic description; frons and clypeus projecting beyond anterior margin of eye in dorsal view; eye occupying slightly less than one-half height of head in lateral view; antenna inserted above ventral margin of eye by about diameter of antennal fossa, eye rather strongly emarginate at insertion; antennal segment 2 relatively long (1.43), 1.90 times width of head; labium length variable, reaching from apex of mesocoxa to well onto abdomen. Thorax (pl. 20): Pronotum as in generic description; mesoscutum broadly exposed. Metathoracic pleuron as in figure 60C. Pretarsus as in figure 60D. Hemelytron : As in generic description. GENI- TALIA (fig. 61, pl. 21): As in generic description but with the following details. Endosoma: Ventral strap with pair of equal-length, narrow spines, one distad and one laterad of secondary gonopore; dorsal strap distad of secondary gonopore long, subapically bifid, terminating in two sharp spines, with faint, broad plate adjacent to secondary gonopore. Phallotheca: Crest moderately large. FEMALE (pl. 20): Coloration as in male; differing from male as in generic description; mean total length 4.01, mean pronotum width 1.11. GENITALIA as in plate 50. ETYMOLOGY: Named after the myrtaceous genus Calytrix , host of many of the known specimens; a noun in apposition. HOSTS: Recorded from Calytrix angulata (pl. 34B), and C. brevifolia (Myrtaceae) ; also recorded Aluta aspera (pl. 34A), Baeckea sp., Darwinia diosmoides (pl. 34D), Leptospermum fastigiatum , and Thryptomene urceolaris (pl. 34F) ( Myrtaceae ). The record from Ricinocarpos velutinus (Euphorbiaceae) is almost certainly not a breeding host. DISTRIBUTION (map 17): Known from the Goldfields-Kalbarri regions of Western Australia. DISCUSSION: Specimens we place in this taxon show some variation in male genitalic structure, notably the fine details of the apical endosomal spines, as well as variation in the length of the labium. We, however, have been unable to recognize a pattern in this variation and therefore treat all specimens as belonging to a single species.
