Name
Schoenlandella diaphaniae (Marsh, 1986) – Wikispecies link – Pensoft Profile
- Cardiochiles diaphaniae Marsh, 1986 (Marsh 1986[1])
- Schoenlandella diaphaniae (Marsh, 1986) (Dangerfield et al. 1999[2])
Material examined
Non-type specimen: Trinidad and Tobago • 1♀; Curepe, Trinidad and Tobago; 21 Jul. 1978. Malaise Trap. Deposited in INHS.
Diagnosis
Members of S. diaphaniae are distinguished from members of S. gloriosa by having shorter lower face and malar space (Fig. 1C); basally hyaline forewing (Fig. 1A); stigma entirely melanic (Fig. 1A).
Description
Marsh (1986)[1] described color of the species and some morphological characters in his species description. Here, the species is re-described based on a specimen collected in Trinidad and Tobago.
Body length 4.5–5.8 mm (Marsh 1986[1]). Antenna length: ~4.2 mm. Forewing length: ~5.5 mm. Head: Antenna 34-segmented. Eye length ~0.45 × longer than its height (40:89). Dorsal width of lower face as long as its height (81:81); Malar space ~0.40 × longer than height of eye in anterior view (32:80), ~2.13 × longer than basal width of mandible (32:15) (Fig. 1C). Clypeus ~1.53 × longer than its width (49:32); clypeal tubercles with sharp margins (Fig. 1C). Galea as long as malar length in lateral view (32:32), with curved apical margin (Fig. 1A). Mesosoma: Scutellar sulcus with five to six crenulae. Postscutellar depression present. Propodeum rugulose; median areola of propodeum diamond-shaped, median length as long as its width; propodeum with median transverse carina reaching lateral margin. Pronotum mostly smooth with incomplete posteroventral carina reaching posterior margin. Mesopleuron mostly smooth and polished; precoxal sulcus medially present with five crenulae. Metapleuron rugulose. Mesosternal sulcus crenulate. Legs: Basal spur on mid tibia ~0.83 × mid-basitarsus (49:59). Hind femur medially ~0.33 × broader than its length (45:137). Basal spur on hind tibia ~0.66 × longer than hind basitarsus (60:90). Hind basitarsus cylindrical. Hind tarsal claw pectinate with five teeth; apical tooth basally rounded and apically angled; basal four teeth sharp. Wings: Forewing second submarginal cell its maximum width ~2.87 × longer than its maximum length (89:31); 3r absent; Rs broken basally and angled at a basal sixth; stigma about ~3.44 × longer than width medially (93:27). Hind wing 2–1A present at basal third (Fig. 1A). Metasoma: Medial length of T1 ~2.59 × longer than medial length of T2 (75:29). Medial length of T2 ~0.22 × longer than its apical width (29:129). T3 about ~1.66 × longer than T2 medially (48:29). Hypopygium entirely sclerotized, medially with shallow area, without median longitudinal fold (Fig. 1D). Ovipositor moderately downcurved. Protruded ovipositor sheath moderately downcurved, ~0.57 × longer than hind tibia (101:176), slightly broadened apically, anterior 2/5 depilous and posterior 3/5 pilose apically with long setae.
Color
Body mostly bright yellow; the following areas melanic: flagellomeres, pedicel mostly, outer scape; ocellary field and frons dorsally, labrum, apical mandible, galea mostly, mid tibia apically, hind coxa apically, hind trochanter and trochantellus, hind femur basally and apically, hind tibia apically, hind tarsomeres apically, entire ovipositor sheath. T4–T6 medially (Fig. 1E). Wings basally hyaline and apically infuscate, C+SC+R vein in forewing mostly melanic, stigma mostly melanic.
Male
See Marsh (1986)[1].
Hosts
Diaphania nitidalis (Stall) and D. hyalinata (L.) (Marsh 1986[1]).
Distribution
Colombia, Venezuela, and Trinidad and Tobago.
