Stirellus catalinus ( Beamer & Tuthill, 1934)   n. rec.

( Figs 3–6 View FIGURE 3 View FIGURE 4 View FIGURE 5 View FIGURE 6 )

Penestirellus catalinus Beamer & Tuthill, 1934: 22   .

Penestirellus   to Stirellus   ; Emeljanov, 1962: 393 [comb. not given]. Description. Length. Male: 2.9–3.2mm; female: 3.2–3.9mm.

Coloration. Overall color varying from ochraceous to yellow green with or without variable symmetrical fuscous marks ( Figs 3 View FIGURE 3 A–I; 5A–E). Crown usually with marks consisting of pair of apical spots, pair of preapical arcuate lines and two pairs of basal spots ( Figs 3 View FIGURE 3 A–G; 5A–D). Frontoclypeus ochraceous with fuscous arcs reaching only part way across ( Figs 3J View FIGURE 3 ; 5F View FIGURE 5 ). Forewing translucent with or without fuscous tint, veins pale ( Figs 3 View FIGURE 3 A–I; 5A–E). Femora and tibiae with dark brown marks ( Figs 3H, I View FIGURE 3 ; 5E View FIGURE 5 ). Abdominal sternites variably infused with dark brown; female sternite VII usually dark brown in contrast to pale segments more basad ( Figs 3K View FIGURE 3 ; 5G View FIGURE 5 ).

Morphology. Head subequal in width to pronotum, subconical, anterior margin rounded to face, acutely angled in dorsal and lateral view ( Figs 3 View FIGURE 3 A–I; 5A–E). Crown longer than width between eyes ( Figs 3 View FIGURE 3 A–G; 5A–D). Anteclypeus tapering to apex, extending beyond normal curve of genae ( Figs 3J View FIGURE 3 ; 5F View FIGURE 5 ). Pronotum median length shorter than median length of crown. Mesonotum and scutellum nearly as long as pronotum ( Figs 3 View FIGURE 3 A–G; 5A–D). Forewing macropterous to submacropterous, usually exposing apex of abdomen in female and sometimes in male, appendix weakly developed, R branches not reflexed ( Figs 3 View FIGURE 3 A–I; 5A–E).

Male genitalia. Pygofer side with few macrosetae dorsally, dorsal margin weakly concave, posterior margin nearly truncate ( Figs 4A, B View FIGURE 4 ; 6A, B View FIGURE 6 ). Subgenital plate distinctly concave laterally in distal half, macrosetae uniseriate, well separated from lateral margin ( Figs 4 View FIGURE 4 D–F; 6D). Style apophysis digitate, relatively robust, laterallylaterally curved, outer margin serrate ( Figs 4G View FIGURE 4 ; 6E View FIGURE 6 ). ConnectiveConnective narrowlynarrowly Y-shaped, stemstem parallelparallel sided, shortershorter thanthan armsarms ( Figs 4H View FIGURE 4 ; 6F View FIGURE 6 ). Aedeagal shaft bent near base but divergent from base throughout length, long, very slightly expanded above bend, nearly straight through most of length, curved slightly anterad at distal fourth, apex blunt ( Figs 4 View FIGURE 4 I–L; 6G–I).

Female. Hind margin of seventh sternum shallowly concave medially, angulate laterally; nearly uniformly dark brown or black, contrasting with paler adjacent abdominal segments ( Figs 3K View FIGURE 3 ; 5G View FIGURE 5 ).

Distribution. Mexico; USA.

Remarks. This species is here recorded from Mexico for the first time. There are two more or less distinct color forms (cf. Figs 3 View FIGURE 3 and 5 View FIGURE 5 ), both of which were collected simultaneously in the same habitats at most Mexican localities listed above. Therefore, these apparently do not represent seasonal forms, as seen in the temperate North American species S. bicolor   .
