Carineta coronida n. sp.

( Fig. 4 )

TYPE MATERIAL.— Holotype. “Balzapamba / 700 m. / 5 May 1938 // Ecuador / Collected by / Wm. Clarke – McIntyre” female ( NCSU) . Paratype. “Balzapamba / 700 m. / 4 May 1938 // Ecuador / Collected by / Wm. Clarke – McIntyre” female ( AFSC) .

REMARKS.—This is a small to medium sized species of Carineta with numerous fasciae on the prothorax and mesothorax.

ETYMOLOGY.—The name is a combination of coronida (Gr. koronis, a curved line, flourish, mark of apostrophe) in reference to the curved markings on the prothorax and mesothorax in this new species.

MEASUREMENTS (MM).—N = two females, mean (range). Length of body: 16.98 (16.95–17.00); length of fore wing: 20.23 (19.85–20.60); width of fore wing: 7.48 (7.45–7.50); length of head: 2.98 (2.95–3.00); width of head including eyes: 5.53 (5.45–5.60); width of pronotum including suprahumeral plates: 6.40 (6.25–6.55); width of mesonotum: 5.65 (5.55–5.75).

DIAGNOSIS.— Carineta coronida n. sp. is a small to medium sized species of Carineta distinguished most easily by its markings. It is similar in size and shape to C. apicalis , C. congrua Walker, 1858b , C. lichiana Boulard, 1986a , C. maracayensis Sanborn 2020a , C. matura Distant, 1882 , C. modesta Sanborn, 2011a , C. spoliata ( Walker, 1858a) , C. tingomariaensis Sanborn 2020b and C. viridicollis ( Germar, 1830) but these species lacks dorsal markings. Similarly, C. seriemaculata Sanborn 2020a lacks the pronotal and lateral sigillae markings and has additional markings on the head and across the posterior mesonotum while C. imperfecta Boulard, 1986b lacks pronotal markings and has only a few mesothoracic spots. Carineta cinara Distant, 1883a has a contrasting mesothorax, lacks the pronotal and mesonotal markings, and has smokey wings not found in the new species. Carineta cingenda Distant, 1883b , C. crocea Distant, 1883b , C. picadae Jacobi, 1907b , C. pictilis Sanborn, 2019b , C. platensis Berg, 1882 , and C. uncinata Sanborn, 2019b lack all pronotal markings found in the new species and the sigillae are piceous or darkened and there are characteristic piceous lines on the dorsal abdomen of C. cingenda not found in the new species. The piceous fascia on the postclypeus and the transverse piceous fascia on C. calida Walker, 1858a quickly distinguishes it from the new species. Carineta garleppi Jacobi, 1907a lacks the pronotal markings and has contrasting sigillae completely margined in piceous. Carineta tetraspila Jacobi, 1907a has a superficial resemblance in terms of markings but has infuscation on the apex of all wings not found in the new species.

DISTRIBUTION.—The species is known only from the type series collected Balsapamba , Bolívar province, in central Ecuador.
