Macrotylus henryi, Salas, Ruth & Schuh, Randall T., 2018

Salas, Ruth & Schuh, Randall T., 2018, Macrotylushenryi, a new species of Pelargonium-feeding Cremnorrhinina from South Africa (Hemiptera, Miridae, Phylinae, Cremnorrhinini), ZooKeys 796, pp. 267-280 : 267

Macrotylus henryi sp. n. Figures 1, 2, 3, 4, 5, 6, Tables 1, 2

Diagnosis.

Placed in Macrotylus Fieber based on the following characteristics: The projecting clypeus, the sparsely distributed, reclining dark common setae on the dorsum (Figs 1, 2A), the pretarsus with deep tarsal claw base and long, apically free pulvillus (Fig. 2F), and the male genitalia with an elongate right paramere, deep left paramere, and the structure of endosoma (Fig. 3). Recognized among Macrotylus spp. by relatively large size; coloration variable, ranging from completely reddish or brownish, to a combination of brownish and reddish or yellow green and reddish, to completely yellow green; moderately projecting face; relatively narrow head, wide pronotum, long second antennal segment, and large eyes (Table 1, Figs 1, 2A); C-shaped endosoma with two sclerotized straps along margins, apical denticles, and subapical secondary gonopore (Fig. 3 A–B).

Distinguished from other South African Macrotylus species by its larger size, vestiture type, and the structure of endosoma. Macrotylus niger mostly black; M. hemizygiae , although often yellow green as in some M. henryi specimens, with shining woolly setae as well as densely placed dark setae on dorsum. These two previously described South African species apparently lacking denticles seen on apex of endosoma in M. henryi (Fig. 3 A–B, Schuh 1974: figs 264, 266). Similar to Denticulophallus Schuh, the other genus of Cremnorrhinina known from South Africa, based on the prominent clypeus, the enlarged free pulvilli, and the structure of endosoma (twisted, sclerotized straps, and apex with several teeth). However, Denticulophallus with a U-shaped endosoma with longer attenuated teeth, medial secondary gonopore, almost totally black coloration, and use of Rutaceae species as hosts ( Schuh 1974, Salas in prep.).

Description.

Male. Relatively large, total length 4.85-6.26, pronotum width 1.20-1.56 (Table 1). Coloration (Fig. 1): Overall coloration mostly reddish, brownish, or yellow green, including appendages, or a combination of yellow green and reddish or brownish and reddish; antennae and legs similar in coloration to dorsum; membrane smoky brown.

Surface and vestiture (Figs 1, 2): Body surface generally with reclining common setae, broadly distributed, scattered on pronotum and scutellum, dark on hemelytra; head, pronotum, scutellum, and clavus anteriorly with sericeous woolly setae; legs also with some erect spine-like setae and tibial spines.

Structure (Figs 1, 2 A–D, Table 1): Head: Moderately elongate and projecting anteriorly, relatively narrow; eyes brownish and relatively large; second antennal segment relatively long, about twice width of head; frons slightly protruding; clypeus relatively elongate and visible from above; labium surpassing hind coxae, but never reaching pygophore.

Thorax: Pronotum wider than long, slightly campanulate, posterior lobe weakly elevated; thoracic pleuron with sericeous setae and scattered common setae, metathoracic scent-gland evaporatory area triangular (Fig. 2D).

Genitalia: Pygophore (Fig. 2E): Occupying about 30% of abdominal length, conical, with ventral and dorsal simple and sericeous setae. Endosoma (Fig. 3 A–B): C-shaped, with dorsal and ventral sclerotized straps seemingly adherent terminally, ventral strap wider than dorsal one; secondary gonopore subapical, moderately large relative to size of endosoma; dorsal strap with 6-9 denticles between midpoint of secondary gonopore and apex of strap; apex of ventral strap serrate and bifid, wider and extending beyond apex of dorsal one. Phallotheca (Figs 2E, 3C): Apical portion conical, dorsal crest well developed. Parameres (Figs 2E, 3 D–E): Relatively large, protruding from genital aperture, with prominent setae; left paramere with posterior process long, apicoventrally serrate, and anterior process short and conical; right paramere elongate, apex blunt.

Female. Coloration, surface, and vestiture (Fig. 1): As in male, but with darker eyes. Structure (Fig. 1, Table 1): As in male, with similar size and body proportions. Genitalia: As in Fig. 4.

Etymology.

Named for Thomas J. Henry.
