Protoneura peramans Calvert in Skinner, 1902: 231 (brief description of ♂ and ♀ from Guatemala in society proceedings);— Calvert (1903: 140, 141, pl. 5, Figs. 48–49; in key, redescription of ♂, description of ♀, illustrations of ♂ S10 and ♀ mesothorax);— Calvert (1907: 395; in key, Guatemala);— Kimmins (1970: 177 –178; designation of ♂ illustrated by Calvert in 1903 as ‘holotype’);— Paulson (1982: 252; Guatemala);— Maes et al. (1988: 32);— González-Soriano (1992: 491–493, Figs. 5–8; diagnosis from P. rojiza, illustrations of ♂ S10 and ♀ thorax and mesostigmal plate);— Boomsma & Dunkle (1996: 25; Belize);— Garrison et al. (2010: 379, 380, fig. 2509; illustration ♀ wings).
Primary types. Syntypes ♂ and ♀. Guatemala, Vera Paz, Panima, [G.C.] Champion leg. [BMNH]. No type designation was made in Calvert’s brief original description on the proceedings of a society meeting, in which only one male and one female in copula were mentioned. In his 1903 redescription Calvert listed 4 ♂ and 2 ♀, including the pair in copula mentioned in 1902, without any indication as to whether the male illustrated in figure 49 was the one collected in copula. In his 1970 catalog, Kimmins considered the specimen illustrated by Calvert in 1903 as holotype. At our request, Benjamin Price kindly checked the specimens deposited at the BMNH, and the male illustrated by Calvert in 1903 with a holotype label from Kimmins was not taken in copula, for which reason it cannot constitute a type since it was not included in the original description. Therefore we here designate the male taken in copula mentioned in Calvert’s (1902) original description (with a paratype label from Kimmins) as lectotype.

[USNM]; 1 ♂ 1 ♀ (in copula), same data but 24–25 viii 1968, T.W. Donnelly leg. [RWG]; Alta Verapaz Dept.: 1 ♂ 1 ♀, Cacao {15°28' N, 90°23' W}, 4 xii 1906, H.S. Barber leg. [USNM]; HONDURAS, Cortés Dept.: 1 ♂ 1 ♀ (in copula), Santo Tomás Camp, camp, river, upstream, 100 m from large swimming pool, Cusuco National Park (15°33'39'' N, 88°17'53'' W, 520 m), 16 vii 2011, M. Jocque leg. [RWG]; NICARAGUA, Matagalpa Dept.: 1 ♂ 1 ♀ (in copula), stream 10 km SE San Ramón {12°54' N, 85°48' W, 700 m}, 18–20 vi 1974, T.W. Donnelly leg. [FSCA].
Characterization. Male: Epicranium black, dorsum of thorax black with orange antehumeral stripe, dorsum of abdomen mostly orange, with black dorsum of S1, small distal spots on S3–4, distal portion of S6–7, distal 3/4 of S8, most of S10; pale colors orange, with yellow limited to venter of thorax (Fig. 14). Pronotum black with orange spots on middle lobe and lateral margins of hind lobe. Mesepisternum black with orange antehumeral stripe extending along basal 3/4 of sclerite; mesepimeron black with orange humeral stripe along distal 3/4 of sclerite, separated from a small distal orange spot; metepisternum black; metepimeron anterior half orange and posterior half black. Coxa dark brown, trochanter and base of femur yellowish brown, remainder of leg dark brown; tibial spurs shorter than twice intervening spaces. Genital ligula lacking lateral lobes, with a v-shaped distal margin, and laterodistal corners projected anteroventrally and pointed (Fig. 84). Cercus shorter than S10 length, about two thirds as long as paraproct, about as long as wide, medially concave and directed lateroposteriorly, semicircular in dorsal view (Fig. 110c), with a pointed ventrobasal tooth directed medially and two apical teeth, a pointed one on ventrodistal margin and a blunt globose one on mediodorsal surface (Figs. 110b, c). Paraproct slightly longer than S10 length, cylindrical, and narrowing to half its basal width at midlength (Fig. 110a). TL 49–53.5; Hw 21.5–22.5. Female: As male but dark colors black with metallic green to copper reflections and pale colors yellow; pronotum anterior lobe with a yellow lateral spot; antehumeral stripe narrow and extending along basal 1/3–1/2 of mesepisternum; humeral stripe narrow and extending along distal 1/2–2/3 of mesepimeron; metepisternum black with a medial yellow stripe across entire height; metepimeron yellow with a black spot on anterodorsal margin; coxa, trochanter, and base of femur yellow or brown margined in yellow, remainder of leg brown; S1–10 black dorsally; pale lateral area of S9 extended dorsally medially to about 1/2 of segment height (Fig. 38). Middle lobe of pronotum lacking pronounced lateral depressions; posterior lobe directed anteriorly and trilobed, with medial lobe bilobed with sides smoothly convex (Fig. 60b). Mesostigmal plate upright and semicircular, at medioposterior corner adjacent to a mesepisternal horn directed anterodorsally (Figs. 60a, c); no depressions behind mesostigmal plates. TL 42.5–45; Hw 23.5–27.
Diagnosis. Male cercus medially concave, directed lateroposteriorly, and semicircular in dorsal view is only shared with P. rojiza (Figs. 110–111). However, in P. rojiza the ventrobasal tooth directed medially is blunt, and both apical teeth are cylindrical and subequal (Figs. 111b, c), rather than pointed and globose and pointed as in P. peramans (Figs. 110b, c), and dorsum of S10 is orange (Fig. 15), not black with orange spots as in P. peramans (Fig. 14). Posteromedial corner of female mesostigmal plate adjacent to a mesepisternal horn directed anteriorly (Fig. 60) is only shared with P. amatoria, but in P. amatoria mesostigmal plate is unmodified (Fig. 48), not upright and semicircular as in P. peramans (Fig. 60). Posterior lobe of female pronotum directed anteriorly and trilobed, with medial lobe bilobed with sides smoothly convex is only shared with P. rojiza (as in Fig. 60), but in P. rojiza the mesepisternal projection adjacent to posteromedial margin of mesostigmal plate is laminar, ventrally appressed against mesanepisternum (Fig. 61) rather than forming a free cylindrical horn as in P. peramans (Fig. 60).
Habitat and biology. Inhabiting creeks and rivers in forested areas. Distribution. Belize south to Nicaragua (Fig. 122).
